Subject: [tex-k] Rendering outside clipped region
Message-ID: <20120206032800.sex1q04tss0o04og@webmail.mit.edu>

Hello,

I encountered some unexpected behaviour with epstopdf today, and I think it is a
bug. I've attached a postscript file I made which has a triangular clipping
region and circles which are both inside and outside the clipping region.

When I open this file with ghostscript, it looks OK. However, when I convert it
to a pdf with

% epstopdf test.ps

the output includes the circles which show up outside the clipped region.

I have also tried using
% ps2epsi test.ps
% epstopdf test.epsi

and again, some (but not all) of the circles outside the clipped region appear.

Is there a command I should be using to avoid this type of problem?
Thank you for your help,
Chris

Try a different ghostscript version.

Hi Chris -- I echo Heiko's thought, that whatever you are seeing is a
function of the Ghostscript version.  In essence, epstopdf just runs
gs -sDEVICE=pdfwrite <more options> ...

When I run your test file using gs 9.04, the result looks right to me,
i.e., clipped.

Perhaps there are some gs options that would help wrt clipping too, but
I don't have anything specific to offer.  Sorry.

Best,
Karl

Hello all,
OK, I think the problem is solved. I have been viewing the pdfs I generate 
with

% evince attachment.pdf

which gives me the error. It's OK with gs 9.04!
