[texhax] \pdfoutput

[Konstantin Karapetyan]

You should use \ifnum\pdfoutput > 0. Here is the definition I use in
my style file:

\newif\ifPDF
\ifx\pdfoutput\undefined\PDFfalse
\else\ifnum\pdfoutput > 0\PDFtrue
\else\PDFfalse
\fi
\fi

Example of use:

\ifPDF
\pdfpagewidth=\paperwidth
\pdfpageheight=\paperheight
\RequirePackage[pdftex]{graphicx}
\else
\RequirePackage[dvips]{graphicx,color}
\fi

HTH.

Happy TeXing!

Konstantin.
