Hi Anna,
I hadn't tried gimp yet so I installed it to see. Works fine in
both gimp and Imagemagick, so I guess it's an xfig thing. I'm running
xfig 3.2.5c which is only slightly newer than yours, but maybe that
broke it.
Thanks, Dave

Friends,
I'm using GRASS 70-svn on Arch linux to generate figures for a
report. The general process is
1) GRASS - d.out.file format=png
2) xfig - import the PNG file, annotate, and export as PDF
3) TeX - import the file in a dvipdfm \special
However, I'm now having problems with non-functional PNG files
from d.out.file. Just below is a paste from my console. You can't
see the error from inside xfig, but the line just below "xfig" is
the stderr output from attempting to import demo_png.png.
******************************__******************************__***********
GRASS 7.0.svn > d.out.file out=demo_png.png format=png size=800,600
Mapset <final> in Location <beartooth>
GRASS 7.0.svn > xfig
Warning: translation table syntax error: Missing '(' while parsing

Warning: String to TranslationTable conversion encountered errors
libpng error: invalid file gamma in png_set_gamma
******************************__******************************__***********
The resulting PNG file will import into Imagemagick OK, and can
then be exported back out as a PNG file which xfig will accept, so
there is a work around, but maybe this is easily fixed? I've had a
look at Anna's python script but haven't gone into the imported modules.
I have never had any problems with exported images from GRASS.
d.out.file uses the same mechanism as when you use the toolbar button in
map display. I tried to get the png into xfig and it didn't complain
(xfig version 3.2.5b). Any other image processing tools have problems
(e.g. gimp)?
Anna
Thanks, Dave
