1 Why use Dvips?

The Dvips program has a number of features that set it apart from other PostScript drivers for TeX. This rather long section describes the advantages of using Dvips, and may be skipped if you are just interested in learning how to use the program. See Installation, for details of compilation and installation.

The Dvips driver generates excellent, standard PostScript, that can be included in other documents as figures or printed through a variety of spoolers. The generated PostScript requires very little printer memory, so very complex documents with a lot of fonts can easily be printed even on PostScript printers without much memory, such as the original Apple LaserWriter. The PostScript output is also compact, requiring less disk space to store and making it feasible as a transfer format.

Even those documents that are too complex to print in their entirety on a particular printer can be printed, since Dvips will automatically split such documents into pieces, reclaiming the printer memory between each piece.

The Dvips program supports graphics in a natural way, allowing PostScript graphics to be included and automatically scaled and positioned in a variety of ways.

Printers with any resolution are supported, even if they have different resolutions in the horizontal and vertical directions. High resolution output is supported for typesetters, including an option that compresses the bitmap fonts so that typesetter virtual memory is not exhausted. This option also significantly reduces the size of the PostScript file and decoding in the printer is very fast.

Missing fonts can be automatically generated if Metafont exists on the system, or fonts can be converted from GF to PK format on demand. If a font cannot be generated, a scaled version of the same font at a different size can be used instead, although Dvips will complain loudly about the poor aesthetics of the resulting output.

One of the most important features is the support of virtual fonts, which add an entirely new level of flexibility to TeX. Virtual fonts are used to give Dvips its excellent PostScript font support, handling all the font remapping in a natural, portable, elegant, and extensible way. Dvips even comes with its own Afm2tfm program that creates the necessary virtual fonts and TeX font metric files automatically from the Adobe font metric files.

Source is provided and freely distributable, so adding a site-specific feature is possible. Adding such features is made easier by the highly modular structure of the program.

There is really no reason to use another driver, and the more people use Dvips, the less time will be spent fighting with PostScript and the more time will be available to create beautiful documents. So if you don’t use Dvips on your system, get it today.

Tom Rokicki wrote and maintains the original Dvips program.

2 Installation

Installing Dvips is mostly the same as installing any Kpathsea-using program. Therefore, for the basic steps involved, see Installation in Kpathsea.

For solutions to common installation problems and information on how to report a bug, see the file kpathsea/BUGS (see Bugs in Kpathsea). For solutions to Dvips-specific problems, see Debug options. Also see the Dvips home page at http://www.radicaleye.com/dvips.

Dvips does require some additional installation, detailed in the sections below. Also, to configure color devices, see Color device configuration.

Next: , Up: Installation   [Contents][Index]

2.1 config.ps installation

Dvips has its own configuration files: a file config.ps for sitewide defaults, and a file config.printer for each printer (output device). Since these are site-specific, make install does not create them; you must create them yourself.

(These Dvips configuration files are independent of the Kpathsea configuration file texmf.cnf (see Config files in Kpathsea).

Dvips configuration files contents and searching are described fully in Config files. The simplest way to create a new configuration file is to copy and modify the file dvipsk/contrib/config.proto, seasoning with options to your taste from Config files. Here is config.proto for your reading pleasure:

% Prototype Dvips configuration file.  (Public domain.)

% How to print, maybe with lp instead lpr, etc.
o |lpr

% Default resolution of this device, in dots per inch.
D 600

% Metafont mode.  (This is completely different from the -M command-line
% option, which controls whether MakeTeXPK is invoked.)  Get
% ftp://ftp.tug.org/tex/modes.mf for a list of mode names.  This mode
% and the D number above must agree, or MakeTeXPK will get confused.

2.2 PostScript font installation

To use PostScript fonts with TeX and Dvips, you need both metric files (.tfm and .vf) and the outlines (.pfa or .pfb). See Font concepts. Current TeX systems come with support for 35 base PostScript fonts and many more.

If you have additional PostScript fonts, you can make them available to Dvips by (1) giving them appropriate filenames; and (2) running Afm2tfm (see Making a font available) to make TFM and VF metrics for TeX and Dvips to use. Also add them to psfonts.map (see psfonts.map); this file must contain everything available in the system. The updmap program is usually used to maintain psfonts.map; run ‘updmap --help’ for lots of information about how it works.

Next: , Previous: , Up: Installation   [Contents][Index]

2.3 Ghostscript installation

Ghostscript is a PostScript interpreter freely available to end-users, originally written by Peter Deutsch. It can read the PostScript produced by Dvips and render it on your monitor, or for another device (e.g., an Epson printer) that does not support PostScript, or in PDF format. The latest version is available via http://ghostscript.com.

The program Ghostview, originally written by Johannes Plass and Tim Theisen, provides typical previewing capabilities (next page/previous page, magnification, etc.). It requires Ghostscript to run, and files in structured Postscript, specifically with ‘%%Page’ comments (no ‘N’ in config.ps). The current version is known as GV, and is available from http://www.gnu.org/software/gv.

2.4 Diagnosing problems

You’ve gone through all the trouble of installing Dvips, carefully read all the instructions in this manual, and still can’t get something to work. The following sections provide some helpful hints if you find yourself in such a situation.

For details on effective bug reporting, common installation problems, and mktexpk problems, see Bugs in Kpathsea.

A good first debugging operation is to set the environment variable DVIPSDEBUG, which will display any configuration and map files read by Dvips. This way you can be sure it’s finding the files and settings you expect.

Next: , Up: Diagnosing problems   [Contents][Index]

2.4.1 Debug options

The ‘-d’ flag to Dvips helps in tracking down certain errors. The parameter to this flag is an integer that tells what errors are currently being tracked. To track a certain class of debug messages, specify the appropriate number given below; if you wish to track multiple classes, sum the numbers of the classes you wish to track. To track all classes, you can use -1.

You can also set the environment variable KPATHSEA_DEBUG instead of using ‘-d’. Some of these debugging options are actually provided by Kpathsea (see Debugging in Kpathsea).

The classes are:












font compression






config files


Kpathsea stat calls


Kpathsea hash table lookups


Kpathsea path element expansion


Kpathsea path searches

2.4.2 No output at all

If you are not getting any output at all, even from the simplest one-character file (for instance, ‘\ \bye’), then something is very wrong. Practically any file sent to a PostScript laser printer should generate some output, at the very least a page detailing what error occurred, if any. Talk to your system administrator about downloading a PostScript error handler. (Adobe distributes a good one called ‘ehandler.ps’.)

It is possible, especially if you are using non-Adobe PostScript, that your PostScript interpreter is broken. Even then it should generate an error message. Dvips tries to work around as many bugs as possible in common non-Adobe PostScript interpreters, but doubtless it misses a few. PowerPage Revision 1, Interpreter Version 20001.001, on a Mitsubishi Shinko CHC-S446i color thermal dye sublimation printer is known to be unable to print with any but builtin fonts.

If Dvips gives any strange error messages, or compilation on your machine generated a lot of warnings, perhaps the Dvips program itself is broken. Try using the debug options to determine where the error occurred (see Debug options).

It is possible your spooler is broken and is misinterpreting the structured comments. Try the ‘-N’ flag to turn off structured comments and see what happens.

Next: , Previous: , Up: Diagnosing problems   [Contents][Index]

2.4.3 Output too small or inverted

If some documents come out inverted or too small, probably your spooler is not supplying an end of job indicator at the end of each file. (This commonly happens on small machines that don’t have spoolers.) You can force Dvips to do this with the ‘-F’ flag (or ‘F’ config file option), but this generates files with a terminating binary character (control-D). You can also try using the ‘-s’ flag (or ‘s’ config file option) to enclose the entire job in a save/restore pair. See Command-line options, and Config files.

Next: , Previous: , Up: Diagnosing problems   [Contents][Index]

2.4.4 Error messages from printer

If your printer returns error messages, the error message gives very good information on what might be going wrong. One of the most common error messages is ‘bop undefined’. This is caused by old versions of Transcript and other spoolers that do not properly parse the setup section of the PostScript. To fix this, turn off structured comments with the ‘-N’ option, but it’d be best to get your spooling software updated.

Another error message is ‘VM exhausted’. Some printers indicate this error by locking up, others quietly reset. This is caused by Dvips thinking that the printer has more memory than it actually does, and then printing a complicated document. To fix this, try lowering the ‘m’ parameter in the configuration file; use the debug option to make sure you adjust the correct file.

Other errors may indicate you are trying to include graphics that don’t nest properly in other PostScript documents, among other things. Try the PostScript file on a QMS PS-810 or other Adobe PostScript printer if you have one, or Ghostscript (see Ghostscript installation); it might be a problem with the printer itself.

Next: , Previous: , Up: Diagnosing problems   [Contents][Index]

2.4.5 Long documents fail to print

This is usually caused by incorrectly specifying the amount of memory the printer has in the configuration file; see the previous section.

Previous: , Up: Diagnosing problems   [Contents][Index]

2.4.6 Including graphics fails

The most common problem with including graphics is an incorrect bounding box (see Bounding box). Complain to whoever wrote the software that generated the file if the bounding box is indeed incorrect.

Another possible problem is that the figure you are trying to include does not nest properly; there are certain rules PostScript applications must follow when generating files to be included. The Dvips program includes work-arounds for such errors in Adobe Illustrator and other programs, but there are certainly applications that haven’t been tested.

One possible thing to try is the ‘-K’ flag which strips the comments from an included figure. This might be necessary if the PostScript spooling software does not read the structured comments correctly. Use of this flag will break graphics from some applications, though, since some applications read the PostScript file from the input stream, looking for a particular comment.

Any application which generates graphics output containing raw binary (not ASCII hex) will probably fail with Dvips.

3 Invoking Dvips

Dvips reads a DVI file as output by (for example) TeX, and converts it to PostScript, taking care of builtin or downloaded PostScript fonts, font reencoding, color, etc. These features are described in other chapters in this document.

There many ways to control Dvips’ behavior: configuration files, environment variables, and command-line options.

Next: , Up: Invoking Dvips   [Contents][Index]

3.1 Basic usage of Dvips

To use Dvips at its simplest, simply type

dvips foo

where foo.dvi is the output of TeX that you want to print. The default output is to a corresponding file foo.ps; Dvips may also have been locally configured to output directly to a printer by default.

If you use fonts that have not been used on your system before, they may be automatically generated; this process can take a few minutes, so progress reports appear by default. The next time that document is printed, these fonts will have been saved in the proper directories, so printing will go much faster. (If Dvips tries to endlessly generate the same fonts over and over again, it hasn’t been installed properly. See Unable to generate fonts in Kpathsea.)

Many options are available (see the next section). For a brief summary of available options, just type

dvips --help

3.2 Command-line options

Dvips has a plethora of command line options. Reading through this section will give a good idea of the capabilities of the driver.

Next: , Up: Command-line options   [Contents][Index]

3.2.1 Option summary

Here is a handy summary of the options; it is printed out when you run Dvips with no arguments or with the standard ‘--help’ option.

3.2.2 Option details

Many of the parameterless options listed here can be turned off by suffixing the option with a zero (‘0’); for instance, to turn off page reversal, use ‘-r0’. Such options are marked with a trailing ‘*’.


Read additional options from standard input after processing the command line.


Print a usage message and exit.


Print the version number and exit.


Conserve memory by making three passes over the DVI file instead of two and only loading those characters actually used. Generally only useful on machines with a very limited amount of memory, like some PCs.


Print only the odd pages. This option uses TeX page numbers, not physical page numbers.

-b num

Generate num copies of each page, but duplicating the page body rather than using the ‘/#copies’ PostScript variable. This can be useful in conjunction with a header file setting ‘bop-hook’ to do color separations or other neat tricks.


Print only the even pages. This option uses TeX page numbers, not physical page numbers.

-c num

Generate num consecutive copies of every page, i.e., the output is uncollated. This merely sets the builtin PostScript variable ‘/#copies’.

-C num

Generate num copies, but collated (by replicating the data in the PostScript file). Slower than the ‘-c’ option, but easier on the hands, and faster than resubmitting the same PostScript file multiple times.

-d num

Set the debug flags, showing what Dvips (thinks it) is doing. This will work unless Dvips has been compiled without the ‘DEBUG’ option (not recommended). See Debug options, for the possible values of num. Use ‘-d -1’ as the first option for maximum output.

-D num

Set both the horizontal and vertical resolution to num, given in dpi (dots per inch). This affects the choice of bitmap fonts that are loaded and also the positioning of letters in resident PostScript fonts. Must be between 10 and 10000. This affects both the horizontal and vertical resolution. If a high resolution (something greater than 400 dpi, say) is selected, the ‘-Z’ flag should probably also be used. If you are using fonts made with Metafont, such as Computer Modern, mktexpk needs to know about the value for num that you use or Metafont will fail. See the file ftp://ftp.tug.org/tex/modes.mf for a list of resolutions and mode names for most devices.

-e num

Maximum drift in pixels of each character from its ‘true’ resolution-independent position on the page. The default value of this parameter is resolution dependent (it is the number of entries in the list [100, 200, 300, 400, 500, 600, 800, 1000, 1200, 1600, 2000, 2400, 2800, 3200, …] that are less than or equal to the resolution in dots per inch). Allowing individual characters to ‘drift’ from their correctly rounded positions by a few pixels, while regaining the true position at the beginning of each new word, improves the spacing of letters in words.


Generate an EPSF file with a tight bounding box. This only looks at marks made by characters and rules, not by any included graphics. In addition, it gets the glyph metrics from the TFM file, so characters that print outside their enclosing TFM box may confuse it. In addition, the bounding box might be a bit too loose if the character glyph has significant left or right side bearings. Nonetheless, this option works well enough for creating small EPSF files for equations or tables or the like. (Of course, Dvips output, especially when using bitmap fonts, is resolution-dependent and thus does not make very good EPSF files, especially if the images are to be scaled; use these EPSF files with care.) For multiple page input files, also specify ‘-i’ to get each page as a separate EPSF file; otherwise, all the pages are overlaid in the single output file.


Run as a filter. Read the DVI file from standard input and write the PostScript to standard output. The standard input must be seekable, so it cannot be a pipe. If your input must be a pipe, write a shell script that copies the pipe output to a temporary file and then points Dvips at this file. This option also disables the automatic reading of the PRINTER environment variable; use ‘-P$PRINTER’ after the ‘-f’ to read it anyway. It also turns off the automatic sending of control-D if it was turned on with the ‘-F’ option or in the configuration file; use ‘-F’ after the ‘-f’ to send it anyway.


Write control-D (ASCII code 4) as the very last character of the PostScript file. This is useful when Dvips is driving the printer directly instead of working through a spooler, as is common on personal systems. On systems shared by more than one person, this is not recommended.


Shift non-printing characters (ASCII 0-32, 127) to higher-numbered positions. This was useful to work around bugs in old versions of Adobe’s PDF reader. It’s more likely to cause problems nowadays.

-h name

Prepend name as an additional header file, or, if name is ‘-’, suppress all header files. Any definitions in the header file get added to the PostScript ‘userdict’.


Make each section be a separate file; a section is a part of the document processed independently, most often created to avoid memory overflow. The filenames are created replacing the suffix of the supplied output file name by a three-digit sequence number. This option is most often used in conjunction with the ‘-S’ option which sets the maximum section length in pages; if ‘-i’ is specified and ‘-S’ is not, each page is output as a separate file. For instance, some phototypesetters cannot print more than ten or so consecutive pages before running out of steam; these options can be used to automatically split a book into ten-page sections, each to its own file.

On the other hand, if your document uses very large fonts or very large included figures, Dvips might take it upon itself to split the output into unwanted sections, to try to avoid overflowing printer memory. See Headers and memory usage, for ways to handle this.


Download only needed characters from Type 1 fonts. This is the default in the current release. Some debugging flags trace this operation (see Debug options). You can also control partial downloading on a per-font basis (see psfonts.map).


Print crop marks. This option increases the paper size (which should be specified, either with a paper size special or with the ‘-T’ option) by a half inch in each dimension. It translates each page by a quarter inch and draws cross-style crop marks. It is mostly useful with typesetters that can set the page size automatically. This works by downloading crop.pro.


Remove comments in included PostScript graphics, font files, and headers; only necessary to get around bugs in spoolers or PostScript post-processing programs. Specifically, the ‘%%Page’ comments, when left in, often cause difficulties. Use of this flag can cause other graphics to fail, however, since the PostScript header macros from some software packages read portion the input stream line by line, searching for a particular comment.

-l [=]num

The last page printed will be the first one numbered num. Default is the last page in the document. If num is prefixed by an equals sign, then it (and the argument to the ‘-p’ option, if specified) is treated as a physical (absolute) page number, rather than a value to compare with the TeX ‘\count0’ values stored in the DVI file. Thus, using ‘-l =9’ will end with the ninth page of the document, no matter what the pages are actually numbered.


Specify manual feed, if supported by the output device.

-mode mode

Use mode as the Metafont device name for path searching and font generation. This overrides any value from configuration files. With the default paths, explicitly specifying the mode also makes the program assume the fonts are in a subdirectory named mode. See TeX directory structure in Kpathsea. If Metafont does not understand the mode name, see Unable to generate fonts in Kpathsea.


Turns off automatic font generation (mktexpk). If mktexpk, the invocation is appended to a file missfont.log (by default) in the current directory. You can then execute the log file to create the missing files after fixing the problem. If the current directory is not writable and the environment variable or configuration file value ‘TEXMFOUTPUT’ is set, its value is used. Otherwise, nothing is written. The name ‘missfont.log’ is overridden by the ‘MISSFONT_LOG’ environment variable or configuration file value.

-n num

Print at most num pages. Default is 100000.


Turns off generation of structured comments such as ‘%%Page’; this may be necessary on some systems that try to interpret PostScript comments in weird ways, or on some PostScript printers. Old versions of TranScript in particular cannot handle modern Encapsulated PostScript. Beware: This also disables page movement, etc., in PostScript viewers such as Ghostview.


Disable the use of Omega extensions when interpreting DVI files. By default, the additional opcodes ‘129’ and ‘134’ are recognized by Dvips as Omega or pTeX extensions and interpreted as requests to set 2-byte characters.


Disable the use of pTeX extensions when interpreting DVI files. By default, the additional opcodes ‘130’ and ‘135’ are recognized by Dvips as Omega extensions and interpreted as requests to set 3-byte characters, and ‘255’ as request to change the typesetting direction.

The only drawback is that the virtual font array will (at least temporarily) require 65536 or more positions instead of the default 256 positions, i.e., the memory requirements of Dvips will be somewhat larger. If you find this unacceptable or encounter another problem with the Omega or pTeX extensions, you can switch off the pTeX extension by using ‘-noptex’, or both by using ‘-noomega’ (but please do send a bug report if you find such problems, see Bugs in Kpathsea).

-o name

Send output to the file name. If ‘-o’ is specified without name (i.e., it is the last thing on the command line), the default is ‘file.ps’ where the input DVI file was ‘file.dvi’. If ‘-o’ isn’t given at all, the configuration file default is used.

If name is ‘-’, output goes to standard output. If the first character of name is ‘!’ or ‘|’, then the remainder will be used as an argument to popen; thus, specifying ‘|lpr’ as the output file will automatically queue the file for printing as usual. (The MS-DOS version will print to the local printer device PRN when name is ‘|lpr’ and a program by that name cannot be found.)

-o’ disables the automatic reading of the PRINTER environment variable, and turns off the automatic sending of control-D. See the ‘-f’ option for how to override this.

-O x-offset,y-offset

Move the origin by x-offset,y-offset, a comma-separated pair of dimensions such as ‘.1in,-.3cm’ (see papersize special). The origin of the page is shifted from the default position (of one inch down, one inch to the right from the upper left corner of the paper) by this amount. This is usually best specified in the printer-specific configuration file.

This is useful for a printer that consistently offsets output pages by a certain amount. You can use the file testpage.tex to determine the correct value for your printer. Be sure to do several runs with the same O value—some printers vary widely from run to run.

If your printer offsets every other page consistently, instead of every page, your best recourse is to use ‘bop-hook’ (see PostScript hooks).

-p [=]num

The first page printed will be the first one numbered num. Default is the first page in the document. If num is prefixed by an equals sign, then it (and the argument to the ‘-l’ option, if specified) is treated as a physical (absolute) page number, rather than a value to compare with the TeX ‘\count0’ values stored in the DVI file. Thus, using ‘-p =3’ will start with the third page of the document, no matter what the pages are actually numbered.

-pp first-last

Print pages first through last; equivalent to ‘-p first -l last’, except that multiple ‘-pp’ options accumulate, unlike ‘-p’ and ‘-l’. The ‘-’ separator can also be ‘:’.

-P printer

Read the configuration file config.printer (printer.cfg on MS-DOS), which typically sets the output name (most likely ‘o |lpr -Pprinter’), resolution, Metafont mode, and perhaps other printer-specific defaults. It works best to put sitewide defaults in the one master ‘config.ps’ file and only things that vary from printer to printer in the ‘config.printer’ files; ‘config.ps’ is read before ‘config.printer’.

A configuration file for eventual creation of Adobe PDF files is provided in ‘config.pdf’ and thus can be loaded with ‘-Ppdf’. It will try to include Type 1 outline fonts into the PostScript file (see Hypertext caveats).

If no ‘-P’ or ‘-o’ is given, the environment variable PRINTER is checked. If that variable exists, and a corresponding config.printer (printer.cfg on MS-DOS) file exists, it is read. See Configuration file searching.


Run quietly. Don’t chatter about pages converted, etc. to standard output; report no warnings (only errors) to standard error.


Output pages in reverse order. By default, page 1 is output first.


Run securely. ‘-R2’ disables both shell command execution in \special (via ‘`’, see Dynamic creation of graphics) and config files (via the ‘E’ option, see Configuration file commands) and opening of any absolute or ..-relative filenames. ‘-R1’, the default, forbids shell escapes but allows absolute filenames. ‘-R0’ allows both.


Enclose the output in a global save/restore pair. This causes the file to not be truly conformant, and is thus not recommended, but is useful if you are driving a deficient printer directly and thus don’t care too much about the portability of the output to other environments.

-S num

Set the maximum number of pages in each ‘section’. This option is most commonly used with the ‘-i’ option; see its description above for more information.

-t papertype

Set the paper type to papertype, usually defined in one of the configuration files, along with the appropriate PostScript code to select it (see Config file paper sizes).

-T hsize,vsize

Set the paper size to (hsize,vsize), a comma-separated pair of dimensions such as ‘.1in,-.3cm’ (see papersize special). It overrides any paper size special in the DVI file. Be careful, as the paper size will stick to a predefined size if there is one close enough. To disable this behavior, use ‘-tunknown’.

-u psmapfile

Set psmapfile to be the file that dvips uses for looking up PostScript font aliases. If psmapfile begins with a ‘+’ character, then the rest of the name is used as the name of the map file, and the map file is appended to the list of map files (instead of replacing the list). In either case, if the name has no extension, then ‘.map’ is added at the end.


Disable a PostScript virtual memory-saving optimization that stores the character metric information in the same string that is used to store the bitmap information. This is only necessary when driving the Xerox 4045 PostScript interpreter, which has a bug that puts garbage on the bottom of each character. Not recommended unless you must drive this printer.


Print the dvips version number and exit.


Download non-resident PostScript fonts as bitmaps. This requires use of mtpk or gsftopk or pstopk or some combination thereof to generate the required bitmap fonts; these programs are supplied with Dvips. The bitmap must be put into psfonts.map as the downloadable file for that font. This is useful only for those fonts for which you do not have real outlines, being downloaded to printers that have no resident fonts, i.e., very rarely.

-x num

Set the magnification ratio to num/1000. Overrides the magnification specified in the DVI file. Must be between 10 and 100000. It is recommended that you use standard magstep values (1095, 1200, 1440, 1728, 2074, 2488, 2986, and so on) to help reduce the total number of PK files generated. num may be a real number, not an integer, for increased precision.

-X num

Set the horizontal resolution in dots per inch to num.

-y num

Set the magnification ratio to num/1000 times the magnification specified in the DVI file. See ‘-x’ above.

-Y num

Set the vertical resolution in dots per inch to num.


Pass ‘html’ hyperdvi specials through to the output for eventual distillation into PDF. This is not enabled by default to avoid including the header files unnecessarily, and use of temporary files in creating the output. See Hypertext.


Compress bitmap fonts in the output file, thereby reducing the size of what gets downloaded. Especially useful at high resolutions or when very large fonts are used. May slow down printing, especially on early 68000-based PostScript printers. Generally recommend today, and can be enabled in the configuration file (see Configuration file commands).

3.3 Environment variables

Dvips looks for many environment variables, to define search paths and other things. The path variables are read as needed, after all configuration files are read, so they override values in the configuration files. (Except for TEXCONFIG, which defines where the configuration files themselves are found.)

See Path specifications in Kpathsea, for details of interpretation of path and other environment variables common to all Kpathsea-using programs. Only the environment variables specific to Dvips are mentioned here.


Write the absolute path names of any configuration or map files to standard output, for debugging. This isn’t done by default because these files are read even before the banner is printed. For voluminous additional debugging, set the environment variable KPATHSEA_DEBUG to ‘-1’ (see Debugging in Kpathsea). (If KPATHSEA_DEBUG is set to any value, it automatically turns on DVIPSDEBUG.)


Default path to search for all fonts. Overrides all the font path config file options and other environment variables (see Supported file formats in Kpathsea).


Default path to search for PostScript header files. Overrides the ‘H’ config file option (see Configuration file commands).


Overrides ‘mktexpk’ as the name of the program to invoke to create missing PK fonts. You can change the arguments passed to the mktexpk program with the MAKETEXPK environment variable; see MakeTeX script arguments in Kpathsea.


Specifies the name of the startup file (see Configuration file searching) which is read after config.ps but before any printer-specific configuration files.


Last-resort sizes for scaling of unfound fonts. Overrides the ‘R’ definition in config files (see Configuration file commands).


Determine the default printer configuration file. (Dvips itself does not use PRINTER to determine the output destination in any way.)


Path to search for Dvips’ config.printer configuration files, including the base config.ps. Using this single environment variable, you can override everything else. (The printer-specific configuration files are called printer.cfg on MS-DOS, but config.ps is called by that name on all platforms.)


Path to search for included graphics files. Overrides the ‘S’ config file option (see Configuration file commands). If not set, TEXINPUTS is looked for. See Supported file formats in Kpathsea.

Previous: , Up: Invoking Dvips   [Contents][Index]

3.4 Dvips configuration files

This section describes in detail the Dvips-specific config.* device configuration files (called *.cfg on MS-DOS), which override the texmf.cnf configuration files generic to Kpathsea which Dvips also reads (see Config files in Kpathsea).

For information about installing these files, including a prototype file you can copy, see config.ps installation.

Next: , Up: Config files   [Contents][Index]

3.4.1 Configuration file searching

The Dvips program loads many different configuration files, so that parameters can be set globally across the system, on a per-device basis, or individually by each user.

  1. Dvips first reads (if it exists) config.ps; it is searched for along the path for Dvips configuration files, as described in Supported file formats in Kpathsea.
  2. A user-specific startup file is loaded, so individual users can override any options set in the global file. The environment variable DVIPSRC, if defined, is used as the specification of the startup file. If this variable is undefined, Dvips uses a platform-specific default name. On Unix Dvips looks for the default startup file under the name $HOME/.dvipsrc, which is in the user’s home directory. On MS-DOS and MS-Windows, where users generally don’t have their private directories, the startup file is called dvips.ini and it is searched for along the path for Dvips configuration files (as described in Supported file formats in Kpathsea.); users are expected to set this path as they see fit for their taste.
  3. The command line is read and parsed: if the ‘-Pdevice’ option is encountered, at that point config.device is loaded. Thus, the printer configuration file can override anything in the site-wide or user configuration file, and it can also override options in the command line up to the point that the ‘-P’ option was encountered. (On MS-DOS, the printer configuration files are called device.cfg, since DOS doesn’t allow more than 3 characters after the dot in filenames.)
  4. If no ‘-P’ option was specified, and also the ‘-o’ and ‘-f’ command line options were not used, Dvips checks the environment variable PRINTER. If it exists, then config.$PRINTER ($PRINTER.cfg on MS-DOS) is loaded (if it exists).

Because the .dvipsrc file is read before the printer-specific configuration files, individual users cannot override settings in the latter. On the other hand, the TEXCONFIG path usually includes the current directory, and can in any case be set to anything, so the users can always define their own printer-specific configuration files to be found before the system’s.

A few command-line options are treated specially, in that they are not overridden by configuration files:


As well as setting the resolution, this unsets the mode, if the mode was previously set from a configuration file. If config.$PRINTER is read, however, any ‘D’ or ‘M’ lines from there will take effect.


This overrides any mode setting (‘M’ line) in configuration files. ‘-mode’ does not affect the resolution.


This overrides any output setting (‘o’ line) in configuration files.

The purpose of these special cases is to (1) minimize the chance of having a mismatched mode and resolution (which ‘mktexpk’ cannot resolve), and (2) let command-line options override config files where possible.

Previous: , Up: Config files   [Contents][Index]

3.4.2 Configuration file commands

Most of the configuration file commands are similar to corresponding command line options, but there are a few exceptions. When they are the same, we omit the description here.

As with command line options, many may be turned off by suffixing the letter with a zero (‘0’).

Within a configuration file, empty lines, and lines starting with a space, asterisk, equal sign, percent sign, or pound sign are ignored. There is no provision for continuation lines.

@ name hsize vsize

Define paper sizes. See Config file paper sizes.


Memory conservation. Same as ‘-a’, see Option details.

b #copies

Multiple copies. Same as ‘-b’, see Option details.

c filename

Include filename as an additional configuration file, read immediately.

D dpi

Output resolution. Same as ‘-D’, see Option details.

e num

Max drift. Same as ‘-e’, see Option details.

E command

Executes the command listed with system(3); can be used to get the current date into a header file for inclusion, for instance. Possibly dangerous; this may be disabled, in which case a warning will be printed if the option is used (and warnings are not suppressed).


Run as a filter. Same as ‘-f’, see Option details.


Shift low-numbered characters; obsolete. Same as ‘-G’, see Option details.

h header

Prepend header to output. Same as ‘h-’, see Option details.

H path

Use path to search for PostScript header files. The environment variable DVIPSHEADERS overrides this.

i n

Make multiple output files. Same as ‘-i -S n’, see Option details.


Partially download Type 1 fonts. Same as ‘-j’, see Option details.


Remove comments from included PostScript files. Same as ‘-K’, see Option details.

m num

Declare num as the memory available for fonts and strings in the printer. The compile-time default is 180000, but this is typically overridden by config.ps or other configuration files. This value must be accurate if memory conservation and document splitting is to work correctly. To determine this value, send the following file to the printer:

%! Hey, we're PostScript
/Times-Roman findfont 30 scalefont setfont 144 432 moveto
vmstatus exch sub 40 string cvs show pop showpage

The number printed by this file is the total memory free; it is usually best to tell Dvips that the printer has slightly less memory, because many programs download permanent macros that can reduce the memory in the printer. Some systems or printers can dynamically increase the memory available to a PostScript interpreter, in which case this file might return a ridiculously low number; for example, the NeXT computer and Ghostscript. In these cases, a value of, say, 10 million is likely fine.

To go all out: If num is zero or negative, Dvips sets the available memory to a very large number (the maximum integer value in C), the idea being that output is not to a printer and thus no splitting of the output is desirable. The Dvips config file config.maxmem is provided to do this conveniently, namely with ‘dvips -Pmaxmem’.

M mode

Metafont mode. Same as ‘-mode’, see Option details.


Disable structured comments. Beware: This also turns off displaying page numbers or changing to specific pagenumbers in PostScript viewers. Same as ‘-N’, see Option details.

o name

Send output to name. Same as ‘-o’, see Option details. In the file config.foo, a setting like this is probably appropriate:

o |lpr -Pfoo

The MS-DOS version will emulate spooling to lpr by printing to the local printer device PRN if it doesn’t find an executable program by that name in the current directory or along the PATH.

O xoff,yoff

Origin offset. Same as ‘-O’, see Option details.

p [+]name

Examine name for PostScript font aliases. Default is psfonts.map. This option allows you to specify different resident fonts that different printers may have. If name starts with a ‘+’ character, then the rest of the name (after any leading spaces) is used as an additional map file; thus, it is possible to have local map files pointed to by local configuration files that append to the global map file. This can be used for font families.

P path

Use path to search for bitmap PK font files is path. The PKFONTS, TEXPKS, GLYPHFONTS, and TEXFONTS environment variables override this. See Supported file formats in Kpathsea.


Run quietly. Same as ‘-q’, see Option details.


Page reversal. Same as ‘-r’, see Option details.

R num1 num2 …

Define the list of default resolutions for PK fonts. If a font size actually used in a document is not available and cannot be created, Dvips will scale the font found at the closest of these resolutions to the requested size, using PostScript scaling. The resulting output may be ugly, and thus a warning is issued. To turn this last-resort scaling off, use a line with just the ‘R’ and no numbers.

The given numbers must be sorted in increasing order; any number smaller than the preceding one is ignored. This is because it is better to scale a font up than down; scaling down can obliterate small features in the character shape.

The environment and config file values ‘DVIPSSIZES’ or ‘TEXSIZES’ override this configuration file setting.

If no ‘R’ settings or environment variables are specified, a list compiled in during installation is used. This default list is defined by the Makefile variable ‘default_texsizes’, defined in the file make/paths.make.


Output global save/restore. Same as ‘-s’, see Option details.

S path

Use path to search for special illustrations (Encapsulated PostScript files or psfiles). The TEXPICTS and then TEXINPUTS environment variables override this.

T path

Use path to search for TFM files. The TFMFONTS and then TEXFONTS environment variables overrides this. This path is used for resident fonts and fonts that can’t otherwise be found.


Work around bug in Xerox 4045 printer. Same as ‘-U’, see Option details.

V path

Use path to search for virtual font files. This may be device-dependent if you use virtual fonts to simulate actual fonts on different devices.

W [string]

If string is supplied, write it to standard error after reading all the configuration files; with no string, cancel any previous ‘W’ message. This is useful in the default configuration file to remind users to specify a printer, for instance, or to notify users about special characteristics of a particular printer.

X num

Horizontal resolution. Same as ‘-X’ (see Option details).

Y num

Vertical resolution. Same as ‘-Y’ (see Option details).


Compress bitmap fonts. Same as ‘-Z’ (see Option details).


Disables execution of system commands, like ‘-R’ (see Option details). If ‘-R’ is specified on the command line, that takes precedence.

4 Paper size and landscape orientation

Most TeX documents at a particular site are designed to use the local standard paper size (letter size in the United States, A4 in Europe). The Dvips program can be customized either sitewide or for a particular printer.

But many documents are designed for other paper sizes. For instance, you may want to design a document that has the long edge of the paper horizontal. This can be useful when typesetting booklets, brochures, complex tables, or many other documents. This type of paper orientation is called landscape orientation (the default orientation is portrait). Alternatively, a document might be designed for ledger or A3 paper.

Since the intended paper size in these cases is a document design decision, not a printing decision, such information should be given in the TeX file and not on the Dvips command line. For this reason, Dvips supports a ‘papersize’ special. It is hoped that this special will become standard over time for TeX previewers and other printer drivers.

Some LaTeX packages, e.g., ‘hyperref.sty’, write a ‘papersize’ special into the DVI file. In this case, you need not and should not attempt to override it manually.

Next: , Up: Paper size and landscape   [Contents][Index]

4.1 ‘papersize’ special

The format of the ‘papersize’ special is


width is the horizontal size of the page, and height is the vertical size. The dimensions supported are the same as for TeX; namely, in (inches), cm (centimeters), mm (millimeters), pt (points), sp (scaled points), bp (big points, the same as the default PostScript unit), pc (picas), dd (didot points), and cc (ciceros).

For a US letter size landscape document, the papersize would be:


An alternate specification of landscape:


This is supported for backward compatibility, but it is hoped that reventually the papersize comment will dominate.

Of course, such a \special only informs Dvips of the desired paper size; you must also adjust \hsize and \vsize in your TeX document typeset to those dimensions.

When using the papersize special, you generally should not also specify -t on the command line (see Option details). The exception is when using a nonstandard paper size that isn’t predefined; in this case, use -t unknown.

The papersize special must occur somewhere on the first page of the document. Some packages, notably ‘hyperref’, insert this special.

Next: , Previous: , Up: Paper size and landscape   [Contents][Index]

4.2 Configuration file paper size command

The ‘@’ command in a configuration file sets the paper size defaults and options. The first ‘@’ command defines the default paper size. It has three possible parameters:

@ [name [hsize vsize]]

If ‘@’ is specified on a line by itself, with no parameters, it instructs Dvips to discard all previous paper size information (possibly from another configuration file).

If three parameters are given, with the first parameter being a name and the second and third being a dimension (as in ‘8.5in’ or ‘3.2cc’, just like in the ‘papersize’ special), then the option is interpreted as starting a new paper size description, where name is the name and hsize and vsize define the horizontal and vertical size of the sheet of paper, respectively. For example:

@ letterSize 8.5in 11in

If both hsize and vsize are zero (you must still specify units!) then any page size will match. If the ‘@’ character is immediately followed by a ‘+’ sign, then the remainder of the line (after skipping any leading blanks) is treated as PostScript code to send to the printer, presumably to select that particular paper size:

@ letter 8.5in 11in
@+ %%BeginPaperSize: Letter
@+ letter
@+ %%EndPaperSize

After all that, if the first character of the line is an exclamation point, then the line is put in the initial comments section of the final output file; else, it is put in the setup section of the output file. For example:

@ legal 8.5in 14in
@+ ! %%DocumentPaperSizes: Legal
@+ %%BeginPaperSize: Legal
@+ legal
@+ %%EndPaperSize

When Dvips has a paper format name given on the command line, it looks for a match by the name; when it has a ‘papersize’ special, it looks for a match by dimensions. The best match found (from the paper size information in the configuration file) is used. The dimensions must match within 5bp.

If nothing matches, a warning is printed and the first paper size with zero dimensions is used; this should be the unknown paper size definition mentioned below, resulting in the actual dimensions being used.

Landscape mode for all paper sizes is automatically supported.

If your printer has a command to set a special paper size, then give dimensions of ‘0in 0in’; the PostScript code that sets the paper size can refer to the dimensions the user requested as ‘hsize’ and ‘vsize’; these will be macros defined in the PostScript that return the requested size in default PostScript units. Also, some printers want ‘BeginPaperSize’ comments and paper size setting commands; others (such as the NeXT) want ‘PaperSize’ comments and they will handle setting the paper size. So paper size entries should typically specify both.

When using a paper size that is not already defined in config.ps, you probably want to say ‘-t unknown’ on the command line; the unknown paper size definition in config.ps has the requisite PostScript incantation to set the PostScript page size, as just described.

If you want no paper size information in the output at all, use ‘-t nopaper’. This is useful with multi-page output that will be processed further. If you just have a single page document, you can use ‘-E’ to get pure EPSF output.

The Perl 5 script contrib/configs/mkdvipspapers in the distribution directory may help in determining appropriate paper size definitions.

Notwithstanding the above, the default letter and a4 paper size definitions in config.ps execute the setpagedevice operator if it exists (it was defined in PostScript Level 2), or the ‘letter’ or ‘a4’ operator if they exist (they are nonstandard and thus perhaps cause failures on certain (unknown) printers). Not executing any page size definition at all confuses PostScript conversion programs such as ps2pdf, so we want to execute one if we can.

The letterSize and A4Size paper size definitions are now synonyms for letter and a4.

Previous: , Up: Paper size and landscape   [Contents][Index]

4.3 Paper trays

Some printers, such as the Hewlett-Packard HP4si, have multiple paper trays. You can set up Dvips to take advantage of this using the bop-hook PostScript variable (see PostScript hooks).

For example, suppose you have an alternate tray stocked with letterhead paper; the usual tray has the usual paper. You have a document where you want the first page printed on letterhead, and the remaining pages on the usual paper. You can create a header file, say firstletterhead.PS, with the following (PostScript) code (bop-hook is passed the current physical page number, which starts at zero):

/bop-hook { dup 0 eq { alternatetray } { normaltray } ifelse } def

where alternatetray and normaltray are the appropriate commands to select the paper trays. On the 4SI, alternatetray is ‘statusdict begin 1 setpapertray end’ and normaltray is ‘statusdict begin 0 setpapertray end’.

Then, include the file with either

5 Interaction with PostScript

Dvips supports inclusion of PostScript figure files (e.g., Encapsulated PostScript), downloading other header files (e.g., fonts), including literal PostScript code, and hypertext.

Next: , Up: Interaction with PostScript   [Contents][Index]

5.1 PostScript figures

Scaling and including PostScript graphics is a breeze—if the PostScript file is correctly formed. Even if it is not, however, the file can usually be accommodated with just a little more work.

Next: , Up: PostScript figures   [Contents][Index]

5.1.1 The bounding box comment

The most important feature of a good PostScript file from the standpoint of including it in another document is an accurate bounding box comment. Every well-formed PostScript file has a comment describing where on the page the graphic is located, and how big that graphic is.

This information is given as the lower left and upper right corners of the box just enclosing the graphic, and is thus referred to as the bounding box. These coordinates are given in the default PostScript units (there are precisely 72 PostScript units to the inch, like TeX big points) with respect to the lower left corner of the sheet of paper.

To see if a PostScript file has a bounding box comment, just look at the first few lines of the file. PostScript files are standard ASCII, so you can use any text editor to do this. If within the first few dozen lines there is a line like

%%BoundingBox: 25 50 400 300

(with any reasonable numbers), chances are very good that the file is Encapsulated PostScript and will work easily with Dvips. If the file contains instead a line like

%%BoundingBox: (atend)

the file is still probably Encapsulated PostScript, but the bounding box is given at the end of the file. Dvips needs it at the beginning. You can move it with that same text editor, or a simple script. (The bounding box is given in this way when the program that generated the PostScript couldn’t know the size in advance, or was too lazy to compute it.)

If the document lacks a ‘%%BoundingBox:’ altogether, you can determine one in a couple of ways. One is to use the ‘bbfig’ program distributed with Dvips in the contrib directory. This can usually find the correct bounding box automatically; it works best with Ghostscript.

If the comment looks like this:

%%BoundingBox: 0 0 612 792

the graphic claims to take up an entire sheet of paper. This is usually a symptom of a bug in the program that generated it.

The other is to do it yourself: print the file. Now, take a ruler, and make the following measurements (in PostScript units, so measure in inches and multiply by 72): From the left edge of the paper to the leftmost mark on the paper is llx, the first number. From the bottom edge of the paper to the bottommost mark on the paper is lly, the second number. From the left edge of the paper to the rightmost mark on the paper is urx, the third number. The fourth and final number, ury, is the distance from the bottom of the page to the uppermost mark on the paper.

Once you have the numbers, add a comment of the following form as the second line of the document. (The first line should already be a line starting with the two characters ‘%!’; if it is not, the file probably isn’t PostScript.)

%%BoundingBox: llx lly urx ury

Or, if you don’t want to modify the file, you can simply write these numbers down in a convenient place and give them in your TeX document when you import the graphic, as described in the next section.

If the document does not have such a bounding box, or if the bounding box is given at the end of the document, or the bounding box is wrong, please complain to the authors of the software package that generated the file.

Next: , Previous: , Up: PostScript figures   [Contents][Index]

5.1.2 The \includegraphics macro for LaTeX

Once the figure file has a bounding box comment (see the previous section) you are ready to import the graphic into a LaTeX document. For LaTeX 2e, you can use the epsf, graphics or graphicx packages, but the last is recommended—it has the most flexible syntax, and is briefly described here. Further information can be found in grfguide or epslatex, which should be included in your LaTeX distribution in DVI, PDF, or other formats. (If you are still using LaTeX 2.09, use epsf.sty).

Just put the following command into your preamble:


Depending on your system, a suitable driver setup may already be present, so that LaTeX automatically produces DVI files suitable for Dvips. In this case you can leave out the ‘[dvips]’ parameter.

Now, at the point you want to include a file foo.eps, enter a line such as:


However, it is usually best to omit the file extension and only use


because then you can process the same LaTeX file with different TeX engines or DVI converters if you also provide suitable graphics files for them, e.g., foo.pdf or foo.png.

The \includegraphics command has many options, specified in ‘key=value’ syntax, to allow you to resize, rotate or trim the included graphic—see grfguide or epslatex. If your file does not have a bounding box comment, you can supply the numbers as determined in the previous section, in the same order they would have been in a normal bounding box comment:

\includegraphics[bb=100 100 500 500]{foo.ps}

Now, save your changes and run LaTeX and Dvips; the output should have your graphic positioned at precisely the point you indicated, occupying the proper amount of space.

PostScript graphics have their origin in the lower left corner. Therefore, in TeX, a graphic will occupy a box that extends far above the line where it is put in, but has depth zero below it. Combining ‘\includegraphics’ with ‘\parbox’ commands or minipages can sometimes be confusing when this is not taken into account.

Next: , Previous: , Up: PostScript figures   [Contents][Index]

5.1.3 Using the EPSF macros

If you are using LaTeX 2e, use the ‘graphics’ or ‘graphicx’ package. See \includegraphics.

If you are using plain TeX or LaTeX 2.09, you need epsf.tex (for plain TeX) and epsf.sty (for LaTeX). For plain TeX, add a line like this near the top of your input file:

\input epsf

If you are using LaTeX 2.09, add the ‘epsf’ style option, as in:


In any case, the above only needs to be done once, no matter how many figures you plan to include.

Now, at the point you want to include a file, enter a line such as:


If you are using LaTeX, you may need to add \leavevmode immediately before the \epsffile command to get certain environments to work correctly. If your file does not have a bounding box comment, you can supply the numbers as determined in the previous section, in the same order they would have been in a normal bounding box comment:

\epsffile[100 100 500 500]{foo.ps}

Now, save your changes and run TeX and Dvips; the output should have your graphic positioned at precisely the point you indicated, occupying the proper amount of space.

The \epsffile macro typesets the figure as a TeX \vbox at the point of the page that the command is executed. By default, the graphic will have its ‘natural’ width (namely, the width of its bounding box). The TeX box will have depth zero and its natural height. By default, the graphic will be scaled by any DVI magnification in effect, just as is everything else in your document. See the next section for more information on scaling.

If you want TeX to report the size of the figure as a message on your terminal when it processes each figure, give the command:


Next: , Up: EPSF macros   [Contents][Index] EPSF scaling

Usually, you will want to scale an EPSF figure to some size appropriate for your document, since its natural size is determined by the creator of the EPS file.

The best way to do this is to assign the desired size to the TeX \epsfxsize or \epsfysize variables, whichever is more convenient for you. That is, put


right before the call to \epsffile. Then the width of the TeX box will be dimen and its height will be scaled proportionately. Similarly, you can set the vertical size with


in which case the height will be set and the width scaled proportionally.

If you set both, both will be honored, but the aspect ratio of the included graphic may necessarily be distorted, i.e., its contents stretched in one direction or the other.

You can resize graphics in a more general way by redefining the \epsfsize macro. \epsffile calls this with two parameters: the natural horizontal and vertical sizes of the PostScript graphic. \epsfsize must expand to the desired horizontal size, that is, the width of the \vbox. Schematically:


Some useful definitions of body:


This definition (the default) enables the default features listed above, by setting \epsfxsize to the same value it had before the macro was called.


Force the natural size by returning the first parameter (the original width).


A special case, equivalent to ‘#1’.


Scale to half the natural size.


Scale to the current \hsize. (In LaTeX, use \textwidth instead of \hsize.)


If the natural width is greater than the current \hsize, scale to \hsize, otherwise use the natural width.

For compatibility with other PostScript drivers, it is possible to turn off the default scaling of included figures by the DVI magnification with the following TeX command:

\special{! /magscale false def}

Use of this command is not recommended because it will make the \epsffile graphics the “wrong” size if global magnification is being used, and it will cause any PostScript graphics to appear improperly scaled and out of position if a DVI to DVI program is used to scale or otherwise modify the document.

DVI magnification is not applied to any output from code you write in ‘bop-hook’ or its ilk (see PostScript hooks),

Previous: , Up: EPSF macros   [Contents][Index] EPSF clipping

By default, clipping is disabled for included EPSF images. This is because clipping to the bounding box dimensions often cuts off a small portion of the figure, due to slightly inaccurate bounding box arguments. The problem might be subtle; lines around the boundary of the image might be half their intended width, or the tops or bottoms of some text annotations might be sliced off. If you want to turn clipping on, just use the command


and to turn clipping back off, use

5.1.4 ‘psfile’ special

The basic special for file inclusion is as follows:

\special{psfile=filename.ps [key=value] … }

This downloads the PostScript file filename.ps such that the current point will be the origin of the PostScript coordinate system. The optional key=value assignments allow you to specify transformations on the PostScript.

The possible keys are:


The horizontal offset (default 0).


The vertical offset (default 0).


The horizontal clipping size (default 612).


The vertical clipping size (default 792).


The horizontal scaling factor, as a percentage (default 100).


The vertical scaling factor, as a percentage (default 100).


The rotation, in degrees (default 0).


Enable clipping to the bounding box (default disabled).

llx, lly, urx, ury

Bounding box of the included image, just as in a %%BoundingBox comment. Values are in big points, and may be fractional.

rhi, rwi

Desired width and height of the resulting figure in the output, in tenths of big points (720 to the inch); may be fractional.

If both rwi and rhi are nonzero, the picture is scaled, possibly losing aspect ratio. If only one of rwi and rhi is nonzero, the picture is scaled, preserving aspect ratio.

The offsets and sizes are given in PostScript units (big points). Thus, for example:

\special{psfile=foo.ps hoffset=72 hscale=90 vscale=90}

will shift the graphics produced by file foo.ps right by one inch and will draw it at 0.9 times normal size. Offsets are given relative to the point of the special command, and are unaffected by scaling or rotation. Rotation is counterclockwise about the origin. The order of operations is to rotate the figure, scale it, then offset it.

For compatibility with older PostScript drivers, it is possible to change the units that ‘hscale’ and ‘vscale’ are given in. This can be done by redefining ‘@scaleunit in ‘SDict by a TeX command such as

\special{! /@scaleunit 1 def}

The ‘@scaleunit’ variable, which is by default 100, is what ‘hscale’ and ‘vscale’ are divided by to yield an absolute scale factor.

5.1.5 Dynamic creation of PostScript graphics files

PostScript is an excellent page description language—but it does tend to be rather verbose. Compressing PostScript graphics files can reduce them by factor of five or more. For this reason, if the name of an included PostScript file ends with .Z or .gz, Dvips automatically runs ‘gzip -d’. For example:

\epsffile[72 72 540 720]{foo.ps.gz}

Since the results of such a command are not accessible to TeX, if you use this facility with the epsf macros, you need to supply the bounding box parameter yourself, as shown.

More generally, if the filename parameter to one of the graphics inclusion techniques starts with a left quote (‘`’), the parameter is instead interpreted as a command to execute that will send the actual file to standard output. For example:

\special{psfile="`gnuplot foo"}

to include the file foo. Of course, the command to be executed can be anything, including using a file conversion utility such as tek2ps or whatever is appropriate. This feature can be disabled with the ‘-R’ command-line option or ‘R’ configuration option.

5.1.6 Fonts in figures

You can use any font available to TeX and Dvips within a graphics file by putting a %*Font: line in the leading commentary of the file. Schematically, this looks like:

%*Font: tfmname scaledbp designbp hex-start:hex-bitstring

Here is the meaning of each of these elements:


The TeX TFM filename, e.g., cmr10. You can give the same tfmname on more than one ‘%*Font’ line; this is useful when the number of characters from the font used needs a longer hex-bitstring (see item below) than conveniently fits on one line.


The size at which you are using the font, in PostScript points (TeX big points). 72bp = 72.27pt = 1in.


The designsize of the font, again in PostScript points. This should match the value in the TFM file tfmname. Thus, for cmr10, it should be ‘9.96265’.


The character code of the first character used from the font, specified as two ASCII hexadecimal characters, e.g., ‘4b’ or ‘4B’ for ‘K’.


An arbitrary number of ASCII hexadecimal digits specifying which characters following (and including) hex-start are used. This is treated as a bitmap. For example, if your figure used the single letter ‘K’, you would use ‘4b:8’ for hex-start and hex-bitstring. If it used ‘KLMNP’, you would use ‘4b:f4’.

MetaPost’s output figures contain lines like this for bitmap fonts used in a MetaPost label (see MetaPost in Web2c).

5.2 PostScript header files

Header files are bits of PostScript included in the output file; generally they provide support for special features, rather than producing any printed output themselves. You can explicitly request downloading header files if necessary for some figure, or to achieve some special effect.

Dvips includes some headers on its own initiative, to implement features such as PostScript font reencoding, bitmap font downloading, handling of \special’s, and so on. These standard headers are the .pro files (for “prologue”) in the installation directory ‘$(psheaderdir)’; they are created from the .lpro (“long prologue”) files in the distribution by stripping comments, squeezing blank lines, etc., for maximum efficiency. If you want to peruse one of the standard header files, read the .lpro version.

The PostScript dictionary stack will be at the ‘userdict’ level when header files are included.

Next: , Up: Header files   [Contents][Index]

5.2.1 Including headers from TeX

In order to get a particular graphic file to work, a certain font or header file might need to be sent first. The Dvips program provides support for this with the ‘header\special. For instance, to ensure that foo.ps gets downloaded:


As another example, if you have some PostScript code that uses a PostScript font not built into your printer, you must download it to the printer. If the font isn’t used elsewhere in the document, Dvips can’t know you’ve used it, so you must include it in the same way, as in:


to include the font definition file for Adobe Utopia Roman.

The header also special allows for specifying some additional code that should be inserted into the PostScript document before and after the file itself, as follows:

\special{header={foo.ps} pre={pre code} post={post code}}

This will insert pre code just before foo.ps and post code just after. It is required to use the (balanced) braces in all of the arguments, including the header, when using this extended syntax.

This allows, for instance, dynamic headers, where some of the content depends on settings from the user in (La)TeX. Another application is the inclusion of graphics inside the PostScript header, so that they can be reused throughout the document, as with logs. That avoids including the same graphic several times. This is implemented in the graphics/graphicx-psmin package.

This extended syntax has one additional feature. When Dvips finds the extended syntax, it will also look in the installed tex/ tree(s) for the header file (foo.ps in our example), and not only in the current directory and dvips tree as the original syntax does. This is because common graphics may well come with packages which are installed in the tex/ tree.

Next: , Previous: , Up: Header files   [Contents][Index]

5.2.2 Including headers from the command line

You can include headers when you run Dvips, as well as from your document (see the previous section). To do this, run Dvips with the option ‘-P header’; this will read the file config.header, which in turn can specify a header file to be downloaded with the ‘h’ option. See Configuration file commands. These files are called header.cfg on MS-DOS.

You can arrange for the same file to serve as a ‘-P’ config file and the downloadable header file, by starting the lines of PostScript code with a space, leaving only the ‘h’ line and any comments starting in the first column. As an example, see contrib/volker/config.* (contrib/volker/*.cfg on MS-DOS). (These files also perform useful functions: controlling duplex/simplex mode on duplex printers, and setting various screen frequencies; contrib/volker/README explains further.)

Previous: , Up: Header files   [Contents][Index]

5.2.3 Headers and memory usage

Dvips tries to avoid overflowing the printer’s memory by splitting the output files into “sections” (see the ‘-i’ option in Option details). Therefore, for all header files, Dvips debits the printer VM budget by some value. If the header file has, in its leading commentary a line of the form

%%VMusage: min max

then max is used. If there is no %%VMusage line, then the size (in bytes) of the header file is used as an approximation. If you want a file to be ignored in the sectioning calculations, use ‘%%VMusage: 0 0’.

Illustrations (figure files) are also checked for %%VMusage line.

Therefore, if your document uses very large fonts or very large included figures, Dvips might take it upon itself to split the output into unwanted sections. If this causes problems, the simplest solution is to use ‘dvips -Pmaxmem’, which reads the Dvips file config.maxmem, which sets Dvips’s idea of the memory available to a very large number. (See the ‘m’ item in Configuration file commands.)

5.3 Literal PostScript

You can include literal PostScript code in your document in several ways.

Next: , Up: Literal PS   [Contents][Index]

5.3.1 " special: Literal PostScript

For simple graphics, or just for experimentation, literal PostScript code can be included. Simply use a \special beginning with a double quote character ‘"’; there is no matching closing ‘"’.

For instance, the following (simple) graphic:

was created by typing:

\vbox to 100bp{\vss % a bp is the same as a PostScript unit
  \special{" newpath 0 0 moveto 100 100 lineto 394 0 lineto
  closepath gsave 0.8 setgray fill grestore stroke}}

You are responsible for leaving space for such literal graphics, as with the \vbox above.

Next: , Previous: , Up: Literal PS   [Contents][Index]

5.3.2 ‘ps’ special

Generally, Dvips encloses specials in a PostScript save/restore pair, guaranteeing that the special will have no effect on the rest of the document. The ‘ps’ special, however, allows you to insert literal PostScript instructions without this protective shield; you should understand what you’re doing (and you shouldn’t change the PostScript graphics state unless you are willing to take the consequences). This command can take many forms because it has had a torturous history; any of the following will work:


(with longer forms taking precedence over shorter forms, when they are present). ‘ps::’ and ‘ps::[end]’ do no positioning, so they can be used to continue PostScript literals started with ‘ps:’ or ‘ps::[begin]’.

Literal PostScript instructions after ‘ps::[nobreak]’ are not broken into lines. This feature may be used to include PostScript comments, for example.

In addition, the variant

\special{ps: plotfile filename}

inserts the contents of filename verbatim into the output (except for omitting lines that begin with %). An example of the proper use of literal specials can be found in the file rotate.tex, which makes it easy to typeset text turned in multiples of 90 degrees.

Next: , Previous: , Up: Literal PS   [Contents][Index]

5.3.3 Literal headers: ‘!\special

You can download literal PostScript header code in your TeX document, for use with (for example) literal graphics code that you include later. The text of a \special beginning with an ‘!’ is copied into the output file. A dictionary SDict will be current when this code is executed; Dvips arranges for SDict to be first on the dictionary stack when any PostScript graphic is included, whether literally (the ‘"’ special) or through macros (e.g., epsf.tex).

For example:

\special{! /reset { 0 0 moveto} def}

Next: , Previous: , Up: Literal PS   [Contents][Index]

5.3.4 PostScript hooks

Besides including literal PostScript at a particular place in your document (as described in the previous section), you can also arrange to execute arbitrary PostScript code at particular times while the PostScript is printing.

If any of the PostScript names bop-hook, eop-hook, start-hook, or end-hook are defined in userdict, they will be executed at the beginning of a page, end of a page, start of the document, and end of a document, respectively.

When these macros are executed, the default PostScript coordinate system and origin is in effect. Such macros can be defined in headers added by the ‘-h’ option or the ‘header=’ special, and might be useful for writing, for instance, ‘DRAFT’ across the entire page, or, with the aid of a shell script, dating the document. These macros are executed outside of the save/restore context of the individual pages, so it is possible for them to accumulate information, but if a document must be divided into sections because of memory constraints, such added information will be lost across section breaks.

The single argument to bop-hook is the physical page number; the first page gets zero, the second one, etc. bop-hook must leave this number on the stack. None of the other hooks are passed arguments.

As an example of what can be done, the following special will write a light grey ‘DRAFT’ across each page in the document:

\special{!userdict begin /bop-hook{gsave 200 30 translate
65 rotate /Times-Roman findfont 216 scalefont setfont
0 0 moveto 0.7 setgray (DRAFT) show grestore}def end}

Using bop-hook or eop-hook to preserve information across pages breaks compliance with the Adobe document structuring conventions, so if you use any such tricks, you may also want to use the ‘-N’ option to turn off structured comments (such as ‘%%Page’). Otherwise, programs that read your file will assume its pages are independent.

Previous: , Up: Literal PS   [Contents][Index]

5.3.5 Literal examples

To finish off this section, the following examples of literal PostScript are presented without explanation:

\def\rotninety{\special{ps:currentpoint currentpoint translate 90
rotate neg exch neg exch translate}}\font\huge=cmbx10 at 14.4truept
\setbox0=\hbox to0pt{\huge A\hss}\vskip16truept\centerline{\copy0
\vbox to 2truein{\special{ps:gsave 0.3 setgray}\hrule height 2in
\vss\special{ps:gsave 1 setgray}\vbox to 0pt{\vskip2pt
\line{\hss\hskip4pt NEAT\hss}\vss}\special{ps:0 setgray}%
\hbox{\raise2pt\line{\hss NEAT\hss}\special{ps:grestore}}\vss}

Some caveats are in order, however. Make sure that each gsave is matched with a grestore on the same page. Do not use save and restore; they can interact with the PostScript generated by Dvips if care is not taken. Try to understand what the above macros are doing before writing your own. The \rotninety macro especially has a useful trick that appears again and again.

Previous: , Up: Interaction with PostScript   [Contents][Index]

5.4 HyperTeXt

Dvips has support for producing hypertext PostScript documents. If you specify the ‘-z’ option, the html: specials described below will be converted into ‘pdfmark’ PostScript operators to specify links. Without ‘-z’, html: specials are ignored.

The resulting PostScript can then be processed by a distiller program to make a PDF file. (It can still be handled by ordinary PostScript interpreters as well.) Various versions of both PC and Unix distillers are supported; Ghostscript includes limited distiller support (see Ghostscript installation).

Macros you can use in your TeX document to insert the specials in the first place are available from CTAN:/support/hypertex. For CTAN info, see unixtex.ftp in Kpathsea.

This hypertext support (and original form of the documentation) was written by Mark Doyle and Tanmoy Bhattacharya as the ‘dvihps’ program. You can retrieve their software and additional documentation via the CTAN reference above. You may also be interested in the Java previewer IDVI, available at http://www.win.tue.nl/~dickie/idvi, and/or in http://www.emrg.com/texpdf.html, which describes the process of making PDF files from TeX files in more detail.

Mail archives for the original project are at http://math.albany.edu:8800/hm/ht/.

Next: , Up: Hypertext   [Contents][Index]

5.4.1 Hypertext caveats

If you intend to go all the way to PDF, you may want to use the standard 35 PostScript fonts exclusively, since other fonts are embedded as bitmaps by default. The Adobe PDF readers are extremely slow when dealing with bitmap fonts and the results look terrible on the screen. Printouts will probably look fine, but may not take full advantage of a high-resolution printer. Alternatively, you can have your fonts embedded as Type 1 scalable outlines. The resulting PostScript files may be larger, but can be effectively rasterized at any resolution. They can also be converted to PDF files that can be used effectively at any screen or printer resolution.

To get the TeX fonts embedded in the PostScript file as Type 1 fonts, add ‘-Ppdf’ to the dvips command line switches. The printout for a run should look something like this:

 dvips report -Ppdf -o report.ps
 This is dvips(k) 5.86 Copyright 1999 Radical Eye Software (www.radicaleye.com)
 ' TeX output 2001.06.15:0837' -> report.ps
 [1] [2<mean1.ps>] [3<bounce1-00.ps>] [4]

An entry like "<cmr10.pfb>" indicates success: dvips found the Computer Modern Roman 10 point font in a PostScript Font Binary file, translated it to an ASCII encoding, and embedded it. You can confirm this by examining the PostScript output file, looking for the section starting %%BeginFont: CMR10 followed by an entry /FontType 1 def.

The ‘-Ppdf’ option requires that the relevant outline (.pfa or .pfb) files be installed (see Font concepts). For example, the cmr10 file might be in /usr/share/texmf/fonts/type1/bluesky/cm/cmr10.pfb. Your TeX distribution may make those fonts available in a separate optional package (e.g., tetex-extra in Debian). Failing that, commercial versions of the Computer Modern fonts are available from Blue Sky; public domain versions - in particular, the lm fonts, and the cm-super fonts, are available from CTAN sites (for CTAN info, see unixtex.ftp in Kpathsea).

You can convert a PostScript file to PDF using distill, which comes with Adobe Acrobat, or ps2pdf, which comes with Ghostscript. The ps2pdf that comes with Ghostscript version 6.0 or earlier will not embed Type 1 fonts. Current recommendations are GNU Ghostscript 6.51 or Aladdin Ghostscript 7.0. You can check the fonts in a PDF file with Acrobat Reader by selecting the menu entries ‘File|Document Info|Fonts’.

Also, the Adobe distillers prior to 2.1 drop trailing space characters (character code 32) from strings. Unfortunately, the PostScript fonts use this character code for characters other than space (notably the Greek letter psi in the Symbol font), and so these characters are dropped. This bug is fixed in version 2.1.

If you can’t upgrade, One workaround is to change all the trailing blanks in strings to a character code that isn’t in the font. This works because the default behavior is to substitute a blank for a missing character, i.e., the distiller is fooled into substituting the right character. For instance, with the Blue Sky fonts, you can globally replace ‘ )’ with ‘\200)’ (with sed, for example) and get the desired result. With the public domain fonts, you will probably have to use a character code in the range 128 to 191 since these fonts duplicate the first 32 characters starting at 192 to avoid MS-DOS problems.

5.4.2 Hypertext specials

Current support for the World Wide Web in the TeX system does not involve modifying TeX itself. We need only define some specials; Arthur Smith (apsmith@aps.org), Tanmoy Bhattacharya, and Paul Ginsparg originally proposed and implemented the following:

html:<a href="xurl">
html:<a name="name">
html:<img src="xurl">
html:<base href="xurl">

Like all TeX \special’s, these produce no visible output, and are uninterpreted by TeX itself. They are instructions to DVI processors only.

Here, xurl is a standard WWW uniform resource locator (URL), possibly extended with a ‘#type.string’ construct, where type is ‘page’, ‘section’, ‘equation’, ‘reference’ (for bibliographic references), ‘figure’, ‘table’, etc. For example,

\special{html:<a href="http://www.maths.tcd.ie/~tim/ch1.dvi#equation.1.1">}

is a link to equation (1.1) in an example document by Tim Murphy.

See the URL http://www.w3.org/hypertext/WWW/Addressing/Addressing.html for a precise description of base URL’s.

Descriptions of the \special’s:


Creates links in your TeX document. For example:

\special{html:<a href="http://www.tug.org/">}\TeX\ Users

The user will be able to click on the text ‘TeX Users Group’ while running Xdvi and get to the TUG home page. (By the way, this is for illustration. In practice, you most likely want to use macros to insert the \special commands; reference above.)


Defines URL targets in your TeX documents, so links can be resolved. For example:

\special{html:<a name="paradise">}Paradise\special{html:</a>}
is exactly where you are right now.

This will resolve an ‘href="#paradise"’. You’ll also have to change the catcode of ‘#’, etc. It’s usually easiest to use existing macro packages which take care of all the details, such as hyperref for LaTeX. The HyperTeX FAQ has more information.


Links to an arbitrary external file. Interactively, a viewer is spawned to read the file according to the file extension and your mailcap file (see the Xdvi documentation).


Defines a base URL that is prepended to all the name targets. Typically unnecessary, as the name of the DVI file being read is used by default.

The ‘img’ and ‘base’ tags are not yet implemented in Dvips or the NeXTSTEP DVI viewer.

6 PostScript fonts

Dvips supports the use of PostScript fonts in TeX documents. To use a PostScript font conveniently, you need to prepare a corresponding virtual font; the program Afm2tfm, supplied with Dvips, helps with that.

All the necessary support for the standard 35 PostScript fonts (‘AvantGarde-Book’ through ‘ZapfDingbats’), plus other freely or commonly available PostScript fonts is available along with Dvips. To use these fonts, you need do nothing beyond what is mentioned in the installation procedure (see Installation). This chapter is therefore relevant only if you are installing new PostScript fonts not supplied with Dvips. (Or if you’re curious.)

Next: , Up: PostScript fonts   [Contents][Index]

6.1 Font concepts

The information needed to typeset using a particular font is contained in two files: a metric file that contains shape-independent information and a glyph file that contains the actual shapes of the font’s characters. A virtual font is an optional additional file that can specify special ways to construct the characters. TeX itself (or LaTeX) look only at the metric file, but DVI drivers such as Dvips look at all three of these files.

An encoding file defines the correspondence between the code numbers of the characters in a font and their descriptive names. Two encoding files used together can describe a reencoding that rearranges, i.e., renumbers, the characters of a font.

Next: , Up: Font concepts   [Contents][Index]

6.1.1 Metric files

A metric file describes properties of the font that are independent of what the characters actually look like. Aside from general information about the font itself, a metric file has two kinds of information: information about individual characters, organized by character code, and information about sequences of characters.

The per-character information specifies the width, height, depth, and italic correction of each character in the font. Any might be zero.

In addition to information on individual characters, the metric file specifies kerning, i.e., adding or removing space between particular character pairs. It further specifies ligature information: when a sequence of input characters should be typeset as a single (presumably different) “ligature” character. For example, it’s traditional for the input ‘fi’ to be typeset as ‘fi’, not as ‘fi’ (with the dot of the ‘i’ colliding with ‘f’). (In English, the only common ligatures are fi, fl, ff, ffi, and ffl.)

Different typesetting systems use different metric file formats:

The Afm2tfm program distributed with Dvips converts an AFM file to a TFM file and performs other useful transformations as well. See Invoking afm2tfm.

Next: , Previous: , Up: Font concepts   [Contents][Index]

6.1.2 Glyph files

Although a metric file (see the previous section) contains information about the spatial and other properties of the character at position 75, say, it contains nothing about what the character at position 75 actually looks like. The glyphs—the actual shapes of the letterforms in a font—are defined by other files, which we call glyph files. TeX itself only reads the TFM file for a font; it does not need to know character shapes.

A glyph file is a file that defines the shapes of the characters in a font. The shapes can be defined either by outlines or by bitmaps.

PostScript fonts are defined as outline fonts: Each character in the font is defined by giving the mathematical curves (lines, arcs, and splines) that define its contours. Different sizes of a character are generated by linearly scaling a single shape. For example, a 10-point ‘A’ is simply half the size of a 20-point ‘A’. Nowadays, outline fonts usually also contain hints—additional information to improve the appearance of the font at small sizes or low resolutions.

Although various kinds of PostScript outline fonts exist, by far the most common, and the only one we will consider, is called Type 1. The glyph files for Postscript Type 1 fonts typically have names ending in ‘.pfa’ (“printer font ASCII”) or ‘.pfb’ (“printer font binary”).

In contrast, glyph files for Computer Modern and the other standard TeX fonts are bitmap fonts, generated from Metafont (‘.mf’) descriptions. The Metafont program distributed with TeX generates bitmaps from these descriptions.

The glyph files for TeX bitmap fonts are usually stored in packed font (PK) files. The names of these files end in ‘.nnnpk’, where nnn is the resolution of the font in dots per inch. For example, cmr10.600pk contains the bitmaps for the ‘cmr10’ font at a resolution of 600dpi. (On DOS filesystems, it’s more likely dpi600\cmr10.pk.)

Metafont actually outputs generic font (GF) files, e.g., cmr10.600gf, but the GF files are usually converted immediately to PK format (using the gftopk utility that comes with TeX) since PK files are smaller and contain the same information. (The GF format is a historical artifact.)

Next: , Previous: , Up: Font concepts   [Contents][Index]

6.1.3 Virtual fonts

A virtual font is constructed by extracting characters from one or more existing fonts and rearranging them, or synthesizing new characters in various ways. The explanation in this manual is intended to suffice for understanding enough about virtual fonts to use them with Dvips. It isn’t a reference manual on virtual fonts. For more information: The primary document on virtual fonts is Donald E. Knuth, TUGboat 11(1), Apr. 1990, pp. 13–23, “Virtual Fonts: More Fun for Grand Wizards” (CTAN:/info/virtual-fonts.knuth; for CTAN info, see unixtex.ftp in Kpathsea). (Don’t be intimidated by the subtitle.)

A virtual font (‘.vf’) file specifies, for each character in the virtual font, a recipe for typesetting that character. A VF file, like a TFM file, is in a compressed binary format. The vftovp and vptovf programs convert a VF file to a human-readable VPL (virtual property list) format and back again. See vftovp invocation in Web2c, and vptovf invocation in Web2c.

In the case of a PostScript font f being used in a straightforward way, the recipe says: character i in the VF font is character j in font f. The font f is called a base font. For example, the VF file could remap the characters of the PostScript font to the positions where TeX expects to find them. See Encodings.

Since TeX reads only TFM files, not VF’s, each VF must have a corresponding TFM for use with TeX. This corresponding TFM is created when you run vptovf.

You can expand virtual fonts into their base fonts with DVIcopy (see dvicopy invocation in Web2c). This is useful if you are using a DVI translator that doesn’t understand vf’s itself.

Next: , Previous: , Up: Font concepts   [Contents][Index]

6.1.4 Encodings

Every font, whatever its type, has an encoding, that specifies the correspondence between “logical” characters and character codes. For example, the ASCII encoding specifies that the character numbered 65 (decimal) is an uppercase ‘A’. The encoding does not specify what the character at that position looks like; there are lots of ways to draw an ‘A’, and a glyph file (see Glyph files) tells how. Nor does it specify how much space that character occupies; that information is in a metric file (see Metric files).

TeX implicitly assumes a particular encoding for the fonts you use with it. For example, the plain TeX macro \', which typesets an acute accent over the following letter, assumes the acute accent is at position 19 (decimal). This happens to be true of standard TeX fonts such as Computer Modern, as you might expect, but it is not true of normal PostScript fonts.

It’s possible but painful to change all the macros that assume particular character positions. A better solution is to create a new font with the information for the acute accent at position 19, where TeX expects it to be. See Making a font available.

PostScript represents encodings as a sequence of 256 character names called an encoding vector. An encoding file (‘.enc’) gives such a vector, together with ligature and kerning information (with which we are not concerned at the moment). These encoding files are used by the Afm2tfm program. Encoding files are also downloaded to the PostScript interpreter in your printer if you use one of them in place of the default encoding vector for a particular PostScript font.

Examples of encodings: the dvips.enc encoding file that comes with the Fontname distribution (http://tug.org/fontname) is a good (but not perfect) approximation to the TeX encoding for TeX’s Computer Modern text fonts. This is the encoding of the fonts that originated with Dvips, such as ptmr.tfm. The distribution includes many other encoding files; for example, 8r.enc, which is the base font for the current PostScript font distribution, and three corresponding to the TeX mathematics fonts: texmext.enc for math extensions, texmital.enc for math italics, and texmsym.enc for math symbols.

6.1.5 How PostScript typesets a character

The output of Dvips is a program in the PostScript language that instructs your (presumably PostScript-capable) printer how to typeset your document by transforming it into toner on paper. Your printer, in turn, contains a PostScript interpreter that carries out the instructions in this typesetting program.

The program must include the definition of any PostScript fonts that you use in your document. Fonts built into your printer (probably the standard 35: ‘Times-Roman’, ‘ZapfDingbats’, …) are defined within the interpreter itself. Other fonts must be downloaded as pfa or pfb files (see Glyph files) from your host (the computer on which you’re running Dvips).

You may be wondering exactly how a PostScript interpreter figures out what character to typeset, with this mass of metrics, glyphs, encodings, and other information. (If you’re not wondering, skip this section …)

The basic PostScript operator for imaging characters is show. Suppose you’ve asked TeX to typeset an ‘S’. This will eventually wind up in the Dvips output as the equivalent of this PostScript operation:

(S) show

Here is how PostScript typesets the ‘S’:

  1. PostScript interpreters use ASCII; therefore ‘S’ is represented as the integer 83. (Any of the 256 possible characters representable in a standard 8-bit byte can be typeset.)
  2. A PostScript dictionary is a mapping of names to arbitrary values. A font, to the interpreter, is a dictionary which contains entries for certain names. (If these entries are missing, the interpreter refuses to do anything with that font.)

    PostScript has a notion of “the current font”—whatever font is currently being typeset in.

  3. One of the mandatory entries in a font dictionary is ‘Encoding’, which defines the encoding vector (see Encodings) for that font. This vector of 256 names maps each possible input character to a name.
  4. The interpreter retrieves the entry at position 83 of the encoding vector. This value is a PostScript name: /S.
  5. For Type 1 fonts (we’re not going to discuss anything else), the interpreter now looks up /S as a key in a dictionary named CharStrings, another mandatory entry in a font dictionary.
  6. The value of S in CharStrings is the equivalent of a series of standard PostScript commands like ‘curveto’, ‘lineto’, ‘fill’, and so on. These commands are executed to draw the character. There can also be hint information that helps adapt the character to low-resolution rasters. (See Glyph files.) The commands are actually represented in a more compact way than standard PostScript source; see the Type 1 book for details.

This method for typesetting characters is used in both Level 1 and Level 2 PostScript. See the PostScript reference manuals for more information.

6.2 Making a PostScript font available

To make a PostScript font available in a TeX document, you need to install the font on your system and then define it within the document. Once you have installed the font, of course, it is available for any document thereafter and you don’t need to reinstall it. You must have an AFM file for any font you install. Unless the font is built into your printer, you must also have a PFA or PFB file.

In the following examples, we use the font ‘Times-Roman’ to illustrate the process. But you should use the prebuilt fonts for Times and the other standard fonts, rather than rebuilding them. The prebuilt fonts are made using a more complicated process than that described here, to make them work as well as possible with TeX. So following the steps in this manual will not generate files identical to the distributed ones. See PostScript font installation, for pointers to the prebuilt fonts.

Installation of a PostScript font proceeds in three steps. See Font concepts, for descriptions of the various files involved.

  1. Run afm2tfm to create a TFM file for the original font, and the VPL form of the virtual font:
    afm2tfm Times-Roman -v ptmr rptmr
  2. Run vptovf to generate a VF and TFM file for the virtual font from the VPL file:
    vptovf ptmr.vpl ptmr.vf ptmr.tfm
  3. Insert an entry for the font in psfonts.map (see psfonts.map):
    rptmr      Times-Roman                 <ptmr8a.pfa
  4. Install the files in the standard locations, as in:
    cp ptmr.vf fontdir/vf/…
    cp *ptmr.tfm fontdir/tfm/…
    cp ptmr.afm fontdir/afm/…
    cp ptmr.pf? fontdir/type1/…

The simplest invocation of Afm2tfm to make virtual fonts goes something like this:

afm2tfm Times-Roman -v ptmr rptmr

This reads the file Times-Roman.afm, and produces two files as output, namely the virtual property list’file ptmr.vpl, and the “raw” font metric file rptmr.tfm. To use the font in TeX, you first run

vptovf ptmr.vpl ptmr.vf ptmr.tfm

You should then install the virtual font file ptmr.vf where Dvips will see it and install ptmr.tfm and rptmr.tfm where TeX and Dvips will see them.

Using these raw fonts is not recommended; there are no raw fonts in the prebuilt PostScript fonts distributed along with Dvips. But nevertheless, that’s how Afm2tfm presently operates, so that’s what we document here. The ‘r’ prefix convention is likewise historical accident.

You can also make more complex virtual fonts by editing ptmr.vpl before running ‘vptovf’; such editing might add the uppercase Greek characters in the standard TeX positions, for instance. (This has already been done for the prebuilt fonts.)

Once the files have been installed, you’re all set. You can now do things like this in TeX:

\font\myfont = ptmr at 12pt
\myfont Hello, I am being typeset in 12-point Times-Roman.

Thus, we have two fonts, one actual (‘rptmr’, which is analogous to the font in the printer) and one virtual (‘ptmr’, which has been remapped to the standard TeX encoding (almost)), and has typesetting know-how added. You could also say

\font\raw = rptmr at 10pt

and typeset directly with that, but then you would have no ligatures or kerning, and you would have to use Adobe character positions for special letters like The virtual font ‘ptmr’ not only has ligatures and kerning, and most of the standard accent conventions of TeX, it also has a few additional features not present in the Computer Modern fonts. For example, it includes all the Adobe characters (such as the Polish ogonek and the French guillemots). The only things you lose from ordinary TeX text fonts are the dotless ‘j’ (which can be hacked into the VPL file with literal PostScript specials if you have the patience) and uppercase Greek letters (which just don’t exist unless you buy them separately). See Reencoding with Afm2tfm.

As a final step you need to record information about both the virtual font and the original font (if you ever might want to use it) in the psfonts.map file (see psfonts.map). For our example, you’d insert the following into psfonts.map:

rptmr      Times-Roman                 <ptmr8a.pfa

Of course, Times-Roman is already built in to most every printer, so there’s no need to download any Type 1 file for it. But if you are actually following these instructions for new fonts, most likely they are not built in to the printer.

These PostScript fonts can be scaled to any size. Go wild! Using PostScript fonts, however, does use up a great deal of the printer’s memory and it does take time. You may find downloading bitmap fonts (possibly compressed, with the ‘Z’ option) to be faster than using the built-in PostScript fonts.

6.3 Invoking Afm2tfm

The Afm2tfm program converts an AFM file for a PostScript font to a TFM file and a VPL file for a corresponding virtual font (or, in its simplest form, to a TFM file for the PostScript font itself). The results of the conversion are affected by the command-line options and especially by the reencodings you can specify with those options. You can also obtain special effects such as an oblique font.

An alternative to Afm2tfm for creating virtual fonts is Alan Jeffrey’s fontinst program, available from CTAN:fonts/utilities/fontinst (for CTAN info, see unixtex.ftp in Kpathsea).

6.3.1 Changing font encodings

Afm2tfm allows you to specify a different encoding for a PostScript font (for a general introduction to encodings, see Encodings). The ‘-t’ option changes the TeX encoding, ‘-p’ changes the PostScript encoding, and ‘-T’ changes both simultaneously, as detailed in the sections below.

Next: , Up: Changing font encodings   [Contents][Index] ‘-t’: Changing TeX encodings

To build a virtual font with Afm2tfm, you specify the ‘-v’ or ‘-V’ option. You can then specify an encoding for that virtual font with ‘-t tex-enc’. (‘-t’ is ignored if neither ‘-v’ nor ‘-V’ is present.) Any ligature and kerning information you specify in tex-enc will be used in the VPL, in addition to the ligature and kerning information from the AFM file.

If the AFM file has no entry for a character specified in tex-enc, that character will be omitted from the output VPL.

The ‘-t’ option is likely to be needed when you have a PostScript font corresponding to a TeX font other than a normal text font such as Computer Modern. For instance, if you have a PostScript font that contains math symbols, you’d probably want to use the encoding in the texmsym.enc file supplied with Dvips. (For a start; to actually get usable math fonts, you have to define much more than just an encoding.)

Next: , Previous: , Up: Changing font encodings   [Contents][Index] ‘-p’: Changing PostScript encodings

By default, Afm2tfm uses the encoding it finds in the AFM file. You can specify a different PostScript encoding with ‘-p ps-enc’. This makes the raw TFM file (the one output by Afm2tfm) have the encoding specified in the encoding file ps-enc. Any ligature or kern information specified in ps-enc is ignored by Afm2tfm, since ligkern info is always omitted from the raw TFM.

If you use this option, you must also arrange to download ps-enc as part of any document that uses this font. You do this by adding a line like the following one to psfonts.map (see psfonts.map):

zpopr Optima "MyEncoding ReEncodeFont" <myenc.enc

Using ‘-p’ is the only way to access characters in a PostScript font that are neither encoded in the AFM file nor constructed from other characters. For instance, Adobe’s ‘Times-Roman’ font contains the extra characters ‘trademark’ and ‘registered’ (among others); these can only be accessed through such a PostScript reencoding.

The ‘8r’ base encoding used for the current PostScript font distribution does do this reencoding, for precisely this reason.

Next: , Previous: , Up: Changing font encodings   [Contents][Index] ‘-T’: Changing both TeX and PostScript encodings

The option ‘-T enc-file’ is equivalent to ‘-p enc-file -t enc-file’. If you make regular use of a private non-standard reencoding ‘-T’ is usually a better idea than the individual options, to avoid unexpected inconsistencies in mapping otherwise. An example of when you might use this option is a dingbats font: when you have a TeX encoding that is designed to be used with a particular PostScript font.

Next: , Previous: , Up: Changing font encodings   [Contents][Index] Reencoding with Afm2tfm

The Afm2tfm program creates the TFM and VF files for the virtual font corresponding to a PostScript font by reencoding the PostScript font. Afm2tfm generates these files from two encodings: one for TeX and one for PostScript. The TeX encoding is used to map character numbers to character names while the PostScript encoding is used to map each character name to a possibly different number. In combination, you can get access to any character of a PostScript font at any position for TeX typesetting.

In the default case, when you specify none of the -t, -p, or -T options, Afm2tfm uses a default TeX encoding (which mostly corresponds to the Computer Modern text fonts) and the PostScript encoding found in the AFM file being read. The reencoding is also sometimes called a remapping.

For example, the default encodings reencode the acute accent in two steps: first the default TeX encoding maps the number 19 to the character name ‘acute’; then the default PostScript encoding, as found in the AFM file for an ordinary PostScript font, maps the character name ‘acute’ to the number 194. (The PostScript encoding works in reverse, by looking in the encoding vector for the name and then yielding the corresponding number.) The combined mapping of 19 to 194 shows up explicitly in the VF file and also implicitly in the fact that the properties of PostScript character 194 appear in position 19 of the TFM file for the virtual font.

The default encoding of the distributed fonts (e.g., ptmr.tfm) mostly follows plain TeX conventions for accents. The exceptions: the Hungarian umlaut (which is at position 0x7D in ‘cmr10’, but position 0xCD in ‘ptmr’); the dot accent (at positions 0x5F and 0xC7, respectively); and the Scandinavian A ring \AA, whose definition needs different tweaking. In order to use these accents with PostScript fonts or in math mode when \textfont0 is a PostScript font, you will need to use the following definitions. These definitions will not work with the Computer Modern fonts for the relevant accents. They are already part of the distributed psfonts.sty for use with LaTeX.

\def\H#1{{\accent"CD #1}}
\def\.#1{{\accent"C7 #1}}
\def\dot{\mathaccent"70C7 }
  \hbox to \wd0{\hss\char'27\hss}}A}

As a kind of summary, here are the ‘CODINGSCHEME’s that result from the various possible choices for reencoding.

default encoding
(CODINGSCHEME TeX text + AdobeStandardEncoding)
-p dc.enc
(CODINGSCHEME TeX text + DCEncoding)
-t dc.enc
(CODINGSCHEME DCEncoding + AdobeStandardEncoding)
-T dc.enc
(CODINGSCHEME DCEncoding + DCEncoding)

The ‘CODINGSCHEME’ line appears in the VPL file but is ignored by Dvips.

Previous: , Up: Changing font encodings   [Contents][Index] Encoding file format

Afm2tfm’s encoding files have the same format as an encoding vector in a PostScript font. Here is a skeletal example:

% Comments are ignored, unless the first word after the percent sign
% is ‘LIGKERN’; see below.
/MyEncoding [ % exactly 256 entries follow, each with a leading ‘/
  /Alpha /Beta /Gamma /Delta …
  /A /B … /Z 
  …  /.notdef /xfooaccent /yfooaccent /zfooaccent
] def

These encoding files are downloaded as part of changing the encoding at the PostScript level (see the previous section).

Comments, which start with a percent sign and continue until the end of the line, are ignored unless they start with ‘LIGKERN’ (see below).

The first non-comment word of the file must start with a forward slash ‘/’ (i.e., a PostScript literal name) and defines the name of the encoding. The next word must be an left bracket ‘[’. Following that must be precisely 256 character names; use ‘/.notdef’ for any that you want to leave undefined. Then there must be a matching right bracket ]. A final ‘def’ token is optional. All names are case-sensitive.

Any ligature or kern information is given as a comment. If the first word after the ‘%’ is ‘LIGKERN’, then the entire rest of the line is parsed for ligature and kern information. This ligature and kern information is given in groups of words: each group is terminated by a space and a semicolon and (unless the semicolon is at the end of a line) another space.

In these LIGKERN statements, three types of information may be specified. These three types are ligature pairs, kerns to ignore, and the character value of this font’s boundary character.

Throughout a LIGKERN statement, the boundary character is specified as ‘||’. To set the font’s boundary character value for TeX:

% LIGKERN || = 39 ;

To indicate a kern to remove, give the names of the two characters (without the leading slash) separated by ‘{}’, as in ‘one {} one ;’. This is intended to be reminiscent of the way you might use ‘{}’ in a TeX file to turn off ligatures or kerns at a particular location. Either or both of the character names can be given as ‘*’, which is a wild card matching any character; thus, all kerns can be removed with ‘* {} * ;’.

To specify a ligature, specify the names of the pair of characters, followed by the ligature operation (as in Metafont), followed by the replacing character name. Either (but not both) of the first two characters can be ‘||’ to indicate a word boundary.

The most common operation is ‘=:’ meaning that both characters are removed and replaced by the third character, but by adding the ‘|’ character on either side of the ‘=:’, you can retain either or both of the two leading characters. In addition, by suffixing the ligature operation with one or two ‘>’ signs, you can make the ligature scanning operation skip that many resulting characters before proceeding. This works just like in Metafont. For example, the ‘fi’ ligature is specified with ‘f i =: fi ;. A more convoluted ligature is ‘one one |=:|>> exclam ;’ which separates a pair of adjacent 1’s with an exclamation point, and then skips over two of the resulting characters before continuing searching for ligatures and kerns. You cannot give more >’s than |’s in an ligature operation, so there are a total of eight possibilities:

=: |=: |=:> =:| =:|> |=:| |=:|> |=:|>>

The default set of ligatures and kerns built in to Afm2tfm is:

% LIGKERN question quoteleft =: questiondown ;
% LIGKERN exclam quoteleft =: exclamdown ;
% LIGKERN hyphen hyphen =: endash ; endash hyphen =: emdash ;
% LIGKERN quoteleft quoteleft =: quotedblleft ;
% LIGKERN quoteright quoteright =: quotedblright ;
% LIGKERN space {} * ; * {} space ; 0 {} * ; * {} 0 ;
% LIGKERN 1 {} * ; * {} 1 ; 2 {} * ; * {} 2 ; 3 {} * ; * {} 3 ;
% LIGKERN 4 {} * ; * {} 4 ; 5 {} * ; * {} 5 ; 6 {} * ; * {} 6 ;
% LIGKERN 7 {} * ; * {} 7 ; 8 {} * ; * {} 8 ; 9 {} * ; * {} 9 ;

6.3.2 Special font effects

Besides the reencodings described in the previous section, Afm2tfm can do other manipulations. (Again, it’s best to use the prebuilt fonts rather than attempting to remake them.)

-s slant’ makes an obliqued variant, as in:

afm2tfm Times-Roman -s .167 -v ptmro rptmro

This creates ptmro.vpl and rptmro.tfm. To use this font, put the line

rptmro Times-Roman ".167 SlantFont"

into psfonts.map. Then ‘rptmro’ (our name for the obliqued Times) will act as if it were a resident font, although it is actually constructed from Times-Roman via the PostScript routine SlantFont (which will slant everything 1/6 to the right, in this case).

Similarly, you can get an expanded font with

afm2tfm Times-Roman -e 1.2 -v ptmrre rptmrre

and by recording the pseudo-resident font

rptmrre Times-Roman "1.2 ExtendFont"

in psfonts.map.

You can also create a small caps font with a command such as

afm2tfm Times-Roman -V ptmrc rptmrc

This will generate a set of pseudo-small caps mapped into the usual lowercase positions and scaled down to 0.8 of the normal cap dimensions. You can also specify the scaling as something other than the default 0.8:

afm2tfm Times-Roman -c 0.7 -V ptmrc rptmrc

It is unfortunately not possible to increase the width of the small caps independently of the rest of the font. If you want a really professional looking set of small caps, you need to acquire a small caps font.

To change the PaintType in a font from filled (0) to outlined (2), you can add "/PaintType 2 store" to psfonts.map, as in the following:

rphvrl   Helvetica "/PaintType 2 store"

Afm2tfm writes to standard output the line you need to add to psfonts.map to use that font, assuming the font is resident in the printer; if the font is not resident, you must add the ‘<filename’ command to download the font. Each identical line only needs to be specified once in the ‘psfonts.map’ file, even though many different fonts (small caps variants, or ones with different output encodings) may be based on it.

Previous: , Up: Invoking afm2tfm   [Contents][Index]

6.3.3 Afm2tfm options


afm2tfm [option]… afmfile[.afm] [tfmfile[.tfm]]

Afm2tfm reads afmfile and writes a corresponding (but raw) TFM file. If tfmfile is not supplied, the base name of the AFM file is extended with ‘.tfm’ to get the output filename.

The simplest example:

afm2tfm Times-Roman rptmr

The TFM file thus created is raw because it omits ligature and kern information, and does no character remapping; it simply contains the character information in the AFM file in TFM form, which is the form that TeX understands. The characters have the same code in the TFM file as in the AFM file. For text fonts, this means printable ASCII characters will work ok, but little else, because standard PostScript fonts have a different encoding scheme than the one that plain TeX expects (see Encodings). Although both schemes agree for the printable ASCII characters, other characters such as ligatures and accents vary. Thus, in practice, it’s almost always desirable to create a virtual font as well with the ‘-v’ or ‘-V’ option. See Making a font available.

The command line options to Afm2tfm:

-c ratio

See ‘-V’; overrides the default ratio of 0.8 for the scaling of small caps.

-e ratio

Stretch characters horizontally by ratio; if less than 1.0, you get a condensed font.


Output all character codes in the ‘vpl’ file as octal numbers, not names; this is useful for symbol or other special-purpose fonts where character names such as ‘A’ have no meaning.

-p ps-enc

Use ps-enc for the destination (PostScript) encoding of the font; ps-enc must be mentioned as a header file for the font in ‘psfonts.map’. See Changing PostScript encodings.

-s slant

Slant characters to the right by slant. If slant is negative, the letters slope to the left (or they might be upright if you start with an italic font).

-t tex-enc

Use tex-enc for the target (TeX) encoding of the font. Ligature and kern information may also be specified in file. file is not mentioned in psfonts.map.

-T ps-tex-enc

Use ps-tex-enc for both the PostScript and target TeX encodings of the font. Equivalent to ‘-p file -t file’.


Use only those characters specified in the TeX encoding, and no others. By default, Afm2tfm tries to include all characters in the input font, even those not present in the TeX encoding (it puts them into otherwise-unused positions, arbitrarily).

-v vpl-file

Output a VPL (virtual property list) file, as well as a TFM file.

-V vpl-file

Same as ‘-v’, but the virtual font generated is a pseudo small caps font obtained by scaling uppercase letters by 0.8 to typeset lowercase. This font handles accented letters and retains proper kerning.

Previous: , Up: PostScript fonts   [Contents][Index]

6.4 psfonts.map: PostScript font catalog

The psfonts.map file associates a PostScript font with related files and constructs. Each line has the format:

filename PostScript-name options

For example, the line

rpstrn StoneInformal <StoneInformal.pfb

causes Dvips to download StoneInformal.pfb (just as if it were a header file, see Header files) if the DVI file (or a virtual font, see Virtual fonts) references the TFM file ‘rpstrn’. The PostScript /FontName of the font defined inside the ‘pfb’ file should be StoneInformal.

You can generate transformed fonts with a line like this:

rpstrc StoneInformal <StoneInformal.pfb ".8 ExtendFont"

See Special font effects, for a complete list of font effects.

You can change the encoding of the Type 1 font at the PostScript level with a ‘ReEncodeFont’ instruction, plus the name of the encoding file. This allows you access to characters that may be present in the Type 1 font file, but not encoded by default—most of the preaccented characters, for example. An example:

pstrn8r StoneInformal "TeXBase1Encoding ReEncodeFont" <8r.enc <pstrn8a.pfb

The ‘8r’ encoding mentioned here has been designed to serve as a base for all downloadable fonts; it allows access to all the characters commonly present in a Type 1 font. For more details, see the 8r.enc source file that comes with (and is installed with) Dvips.

You may notice that the same syntax is used for downloading encoding vectors and Type 1 font files. To make your intentions clear, you can also use ‘<[’ to explicitly indicate you are downloading an encoding vector, as in:

pstrn8r StoneInformal "TeXBase1Encoding ReEncodeFont" <[8r.enc <pstrn8a.pfb

If the filename of your encoding vector does not end in ‘.enc’, and you are using partial font downloading, you must use the ‘<[’ syntax, or Dvips will not download the font properly.

Similarly, the name of the Type 1 font file itself must have extension .pfa or .pfb for partial downloading to work properly.

When using PFB files, Dvips is smart enough to unpack the binary PFB format into printable ASCII so there is no need to perform this conversion yourself. In addition, Dvips scans the font to determine its memory usage, just as it does for other header files (see Header files).

If the ‘j’ config file or command-line option is enabled (as it is by default), StoneInformal.pfb will be partially downloaded—only those characters your document actually uses will be extracted and downloaded, and the remainder discarded. See Option details.

Adobe Multiple Master fonts, such as Minion, cannot be partially downloaded. To partially download in general, but avoid partial downloading for individual fonts, use ‘<<’ instead ‘<’:

pmnr8r Minion <<Minion.pfb

Here is a brief summary of how psfonts.map is read:

  1. If a line is empty or begins with a space, percent, asterisk, semicolon, or hash mark, it is ignored.
  2. Otherwise, the line is separated into words, where words are separated by spaces or tabs, except that if a word begins with a double quote, it extends until the next double quote or the end of the line.
  3. If a word starts with ‘<<’, it is taken as a font file to be wholly downloaded. Use this to avoid partial downloading, as described above.
  4. If a word starts with ‘<[’, it is taken as an encoding file to be downloaded. Use this if the name of the encoding file does end in ‘.enc’, also as described above.
  5. If a word starts with a ‘<’ character, it is treated as a header file that needs to be downloaded. If the name ends in ‘.pfa’ or ‘.pfb’, it is taken as Type 1 font file that will be partially downloaded if the ‘j’ option is in effect. There can be more than one such header for a given font. If a ‘<’ is a word by itself, the next word is taken as the name of the header file.
  6. If a word starts with a ‘"’ character, it is taken as PostScript code used in generating that font, and is inserted into the output verbatim at the appropriate point. (And the double quotes beginning and ending the word are removed.)
  7. Otherwise the word is a name. The first such name is the TFM file, that either a DVI file or a virtual font file can refer to. If there is a second name, it is used as the PostScript name and should match what is defined in the downloaded file; if there is only one name, it is used for both the TeX name and the PostScript name.

7 Color

Dvips supports one-pass multi-color printing of TeX documents on any color PostScript device. Initially added by Jim Hafner, IBM Research, hafner@almaden.ibm.com, the color support has gone through many changes by Tomas Rokicki. Besides the source code support itself, there are additional TeX macro files: ‘colordvi.tex’ and ‘blackdvi.tex’, and corresponding ‘.sty’ versions for use with LaTeX.

In this section we describe the use of color from the document preparer’s point of view and then add some instructions on installation for the TeX administrator.

Next: , Up: Color   [Contents][Index]

7.1 Color macro files

All the color macro commands are defined in ‘colordvi.tex’ (or ‘colordvi.sty’). To access these macros simply add to the top of your plain TeX file the command:

\input colordvi

For (the obsolete) LaTeX 2.09, add the ‘colordvi’ style option as in:


For LaTeX 2e, these examples are not applicable. Instead, please see the documentation for the graphics package, available from CTAN:doc/latex/graphics/. See also CTAN:doc/epslatex.ps.

These macros provide two basic kinds of color macros: ones for local color changes (a few words, a single symbol) and one for global color changes (the whole document). All the color names use a mixed case scheme to avoid conflicts with other macros. There are 68 predefined colors, with names taken primarily from the Crayola crayon box of 64 colors, and one pair of macros for the user to set his own color pattern (see User-definable colors). You can browse the file ‘colordvi.tex’ for a list of the predefined colors. The comments in this file also show a rough correspondence between the crayon names and Pantones.

A local color command has the form

\ColorName{this is the color ColorName}

where ColorName is the name of a predefined color, e.g., ‘Blue’. As shown, these macros take one argument, the text to print in the specified color. This can be used for nested color changes since it restores the original color state when it completes. For example:

This text is normal but here we are \Red{switching to red,
\Blue{nesting blue}, recovering the red} and back to original.

The color nesting level has no hard limit, but it is not advisable to nest too deeply lest you and the reader lose track of the color history.

The global color command has the form


These macros take no arguments and changes the default color from that point on to ColorName. This of course can be overridden globally by another such command or locally by local color commands. For example, expanding on the example above, we might have

This text is green but here we are \Red{switching to red, 
\Blue{nesting blue}, recovering the red} and back to 
original green.
The text from here on will be cyan until
\Yellow{locally changed to yellow}. Now we are back to cyan.

The color commands will even work in math mode and across math mode boundaries. This means that if you have a color before going into math mode, the mathematics will be set in that color as well. In alignment environments like \halign, ‘tabular’ or ‘eqnarray’, local color commands cannot extend beyond the alignment characters.

Because local color commands respect only some environment and delimiter changes besides their own, care must be taken in setting their scope. It is best not to have them stretch too far.

At the present time there are no macros for color environments in LaTeX which might have a larger range. This is primarily to keep the TeX and LaTeX use compatible.

Next: , Previous: , Up: Color   [Contents][Index]

7.2 User-definable colors

There are two ways for the user to specify colors not already defined. For local changes, there is the command \Color which takes two arguments. The first argument is four numbers between zero and one and specifies the intensity of cyan, magenta, yellow and black (CMYK) in that order. The second argument is the text that should appear in the given color. For example, suppose you want the words “this color is pretty” to appear in a color which is 50% cyan, 85% magenta, 40% yellow and 20% black. You would use the command

\Color{.5 .85 .4 .2}{this color is pretty}

For global color changes, there is a command \textColor which takes one argument, the CMYK quadruple of relative color intensities. For example, if you want the default color to be as above, then the command

\textColor{.5 .85 .4 .2}
The text from now on will be this pretty color

will do the trick.

Making a global color change in the midst of nested local colors is highly discouraged. Consequently, Dvips will give you warning message and do its best to recover by discarding the current color history.

7.3 Color subtleties

Color macros are defined via \special keywords. As such, they are put in the ‘.dvi’ file only as explicit message strings to the driver. The (unpleasant) result is that certain unprotected regions of the text can have unwanted color side effects. For example, if a color region is split by TeX across a page boundary, then the footers of the current page (e.g., the page number) and the headers of the next page can inherit that color. To avoid this effect globally, users should make sure that these special regions of the text are defined with their own local color commands. For example, to protect the header and footer in plain TeX, use

\headline{\Black{My Header}}

This warning also applies to figures and other insertions, so be careful!

Of course, in LaTeX, this is much more difficult to do because of the complexity of the macros that control these regions. This is unfortunate but inevitable, because TeX and LaTeX were not written with color in mind.

Even when writing your own macros, much care must be taken. The macros that ‘colorize’ a portion of the text work prefix the text work by outputting one \special command to turn the color on before the text, and outputting another \special command afterwards to restore the original color. It is often useful to ensure that TeX is in horizontal mode before the first special command is issued; this can be done by prefixing the color command with \leavevmode.

7.4 Printing in black/white after colorizing

If you have a TeX or LaTeX document written with color macros and you want to print it in black and white there are two options. On all (good) PostScript devices, printing a color file will print in corresponding gray levels. This is useful to get a rough idea of the colors without using expensive color printing devices. The second option is to replace the call to input colordvi.tex with ‘blackdvi.tex’ (and similarly for the ‘.sty’ files). So in the above example, replacing the word ‘colordvi’ with ‘blackdvi’ suffices. blackdvi.tex defines the color macros as no-ops, and so will produce normal black/white printing. By this simple mechanism, the user can switch to all black/white printing without having to ferret out the color commands. Also, some device drivers, particularly non-PostScript ones like screen previewers, will simply ignore the color commands and so print in black/white. Hopefully, in the future screen previewers for color displays will be compatible with some form of color support.

7.5 Color device configuration

To configure Dvips for a particular color device you need to fine tune the color parameters to match your device’s color rendition. To do this, you will need a Pantone chart for your device. The header file ‘color.lpro’ shows a (rough) correspondence between the Crayola crayon names and the Pantone numbers and also defines default CMYK values for each of the colors. Note that these colors must be defined in CMYK terms and not RGB, as Dvips outputs PostScript color commands in CMYK. This header file also defines (if they are not known to the interpreter) the PostScript commands ‘setcmykcolor’ and ‘currentcmykcolor’ in terms of a RGB equivalent so if your device only understands RGB, there should be no problem.

The parameters set in this file were determined by comparing the Pantone chart of a Tektronix Phaser printer with the actual Crayola Crayons. Because these were defined for a particular device, the actual color rendition on your device may be very different. There are two ways to adjust this. One is to use the PAntone chart for your device to rewrite ‘color.lpro’ prior to compilation and installation. A better alternative, which supports multiple devices, is to add a header file option in the configuration file (see Configuration file commands) for each device that defines, in ‘userdict’, the color parameters for those colors that need redefining.

For example, if you need to change the parameters defining ‘Goldenrod’ (approximately Pantone 109 on the Phaser) for your device ‘mycolordev’, do the following. In the Pantone chart for your device, find the CMYK values for Pantone 109. Let’s say they are ‘{\ 0 0.10 0.75 0.03 }’. Then create a header file named ‘mycolordev.pro’ with the commands

userdict begin 
/Goldenrod { 0 0.10 0.75 0.03 setcmykcolor} bind def

Finally, in ‘config.mycolordev’ add the line

h mycolordev.pro

This will then define ‘Goldenrod’ in your device’s CMYK values in userdict which is checked before defining it in TeXdict by color.pro. (On MS-DOS, you will have to call this file mycolordev.cfg.)

This mechanism, together with additions to colordvi.tex and blackdvi.tex (and the ‘.sty’ files), can also be used to predefine other colors for your users.

7.6 Color support details

To support color, Dvips recognizes a certain set of specials. These specials start with the keyword ‘color’ or the keyword ‘background’, followed by a color specification.

Next: , Up: Color support details   [Contents][Index]

7.6.1 Color specifications

What is a color specification? One of three things. First, it might be a PostScript procedure as defined in a PostScript header file. The color.pro file defines 64 of these, including ‘Maroon’. This PostScript procedure must set the current color to be some value; in this case, ‘Maroon’ is defined as ‘0 0.87 0.68 0.32 setcmykcolor’.

The second possibility is the name of a color model (initially, one of ‘rgb’, ‘hsb’, ‘cmyk’, or ‘gray’) followed by the appropriate number of parameters. When Dvips encounters such a macro, it sends out the parameters first, followed by the string created by prefixing ‘TeXcolor’ to the color model. Thus, the color specification ‘rgb 0.3 0.4 0.5’ would generate the PostScript code ‘0.3 0.4 0.5 TeXrgbcolor’. Note that the case of zero arguments is disallowed, as that is handled by the single keyword case (‘Maroon’) above, where no changes to the name are made before it is sent to the PostScript file.

The third and final type of color specification is a double quote followed by any sequence of PostScript. The double quote is stripped from the output. For instance, the color specification ‘"AggiePattern setpattern’ will set the ‘color’ to the Aggie logo pattern (assuming such exists.)

Previous: , Up: Color support details   [Contents][Index]

7.6.2 Color specials

We will describe ‘background’ first, since it is the simplest. The ‘background’ keyword must be followed by a color specification. That color specification is used as a fill color for the background. The last ‘background’ special on a page is the one that gets issued, and it gets issued at the very beginning of the page, before any text or specials are sent. (This is possible because the prescan phase of Dvips notices all of the color specials so that the appropriate information can be written out during the second phase.)

The ‘color’ special itself has three forms. The first is just ‘color’ followed by a color specification. In this case, the current global color is set to that color; the color stack must be empty when such a command is executed.

The second form is ‘color push’ followed by a color specification. This saves the current color on the color stack and sets the color to be that given by the color specification. This is the most common way to set a color.

The final version of the ‘color’ special is just ‘color pop’, with no color specification; this says to pop the color last pushed on the color stack from the color stack and set the current color to be that color.

Dvips correctly handles these color specials across pages, even when the pages are repeated or reversed.

These color specials can be used for things such as patterns or screens as well as simple colors. However, note that in the PostScript, only one color specification can be active at a time. For instance, at the beginning of a page, only the bottommost entry on the color stack is sent; also, when a color is popped, all that is done is that the color specification from the previous stack entry is sent. No ‘gsave’ or ‘grestore’ is used. This means that you cannot easily mix usage of the ‘color’ specials for screens and colors, just one or the other. This may be addressed in the future by adding support for different categories of color-like state.
