Bug 32491 – Groff pic2graph bug

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Danny 2003-11-01 13:34:13 UTC]

pic2graph will fail on line 48.  It is missing ";;" at the end of line above it, 
this much is obvious.  However fixing this doesn't seem to make it work.  It 
seems to have trouble with the tmp directory.  I found a fixed version of 
pic2graph but it uses an option (-e) that isn't available in version 1.18 of 
grops.

Upgrading to Groff version 1.19 should fix the entire pic2graph problem.

Reproducible: Always
Steps to Reproduce:
1. fix pic2graph by putting ;;
2. try to run pic2graph
   for example "pic2graph < glider.pic > glider.png", if you don't have a pic to 
test with you can get the glider.pic from: http://www.catb.
org/~esr/hacker-emblem/glider.pic

Actual Results:  
you get the error:
convert: Postscript delegate failed [No such file or directory].

Expected Results:  
created the png file

Created attachment 20077 [details]
pic2graph 1.4

This is a supposedly working pic2graph script, however it seems to use a
grops
option which is not supported in 1.18.

Thanks for the bug report Danny.

I recently fixed the pic2graph script to include the extra ';;' on
line 47 (see bug #32300.) The error you are reporting looks like one
of the device parameters passed by the ImageMagick convert utility to
ghostscript is invalid. Can you try pic2graph with ImageMagick-5.5.7;
this later version changed the way in which the postscript coder calls
ghostscript.

[Comment 3 Danny 2003-11-03 08:18:01 UTC]

Ah, after upgrading to ImageMagick-5.5.7-r2 the fixed pic2graph script works.
 I don't have much experiance with ebuilds, is there some way to say that
if you have ImageMagick installed you need to have 5.5.7 or later?

Can we request the ImageMagick maintainer bumps this version to stable x86
soon?

[Comment 4 Danny 2003-11-03 09:28:36 UTC]

I just noticed my pic's seem to have their tops cut off.  I tried emerging
ImageMagick-5.5.7.11 and it's still happening.  Perhaps its just a change
in the way PICs are parsed by I can't find anything about it.  Is anyone
else noticing this?

[Comment 5 Brandy Westcott (RETIRED) 2003-11-29 22:06:36 UTC]

Danny, thanks for being patient. :)

Your cropping problem is caused by a your groff setup. pic2graph converts the
pic file into a postscript file (the page size of the ps file is determined by
your 'papersize' setting in /usr/share/groff/1.18.1/font/devps/DESC; if you're
in the US or Canada this should probably be 'papersize letter'.) Then
pic2graph uses 'convert' from ImageMagick to convert the ps file into a png
image (the pagesize defaults to US letter in ImageMagick). Since you have
'papersize a4' in DESC you're going from an A4 pagesize to a US letter
pagesize and losing part of the image in the process.

To fix this, you'll need to set 'papersize letter' in
/usr/share/groff/1.18.1/font/devps/DESC, or run pic2graph passing '-page a4'
as an argument:

	# pic2graph -page a4 < glider.pic > glider.png
