Description pavel sanda 2006-10-27 15:18:14 UTC

when i try to convert postscript file (see attachment) i get the following error:
$ pstoimg bum.ps
pstoimg V2002-2-1 (Revision 1.19, Perl 5.008008)
pstoimg: Processing bum.ps
pstoimg: Error: "/usr/bin/ppmquant 256 < /tmp/p14449.pnm | /usr/bin/pnmtopng  > bum.png" failed: Bad file descriptor

when the output from gnuplot is the same picture in 
monochromatic colors no error occurs, which is probably caused 
by the fact that ppmquant is not called.

using dev-tex/latex2html-2002.2.1_pre20041025-r1.
(i have tried both netpbm 10.36.0 and 10.34)

Comment 3 pavel sanda 2007-01-09 13:48:00 UTC

this bug shares the eroror  message with 111188 , but it is not the same error,
as bug-file for 111188 works without problems for me.
i will add patch for this bug soon

Comment 4 pavel sanda 2007-01-09 14:00:47 UTC

this bug is caused by the fact, that the intermediate .pnm file created in pstoimg
consists of two images (see pamfile -allimages).
older versions of netpbm ignored this fact and just took the first
one, however the new version check this and pnmquant fails with error.

my fix simply takes only the first image, which is then used for pnmquant.
see patch for pstoimg.

hmm you have the -multipage option for this.
admitedly the error message is weird and that patch could be useful, but then i'll need one that applies when building latex2html
