Note: Ubuntu 14.04 converts it right... ubuntu14$ fig2dev -L gif archoak.fig > xxx.gif ubuntu14$ I put the ubuntu output in an attachment. Created attachment 1196073 [details]
ubuntu 14.04 output file xxx.gif
Created attachment 1196074 [details]
fedora 23 output file xxx.gif
If I comment out the line in transfig/fig2dev/dev/readpng.c:
// png_set_gamma(png_ptr, 2.2, gamma);
everything works again.
Please fix!
I think it is due to the alpha transparency of the km-1635.png image. If I do: $ cd images $ convert km-1635.png xxx.png $ mv xxx.png km-1635.png it works. But the alpha transparency is gone. Ref: http://www.imagemagick.org/script/convert.php https://docs.gimp.org/en/gimp-using-web-transparency.html This does it: $ cd images $ convert -alpha Set km-1635.png km-1635.png $ convert -alpha Set 6015.png 6015.png $ convert -alpha Set hpcp1215.png hpcp1215.png $ convert -alpha Set p2014.png p2014.png $ convert -alpha Set p1505.png p1505.png $ convert -alpha Set CP1025nw.png CP1025nw.png $ cvs com $ Don't know why it does it, though. The transparency is on in both cases. When trying to reproduce I came across other issues: What I did: # dnf install transfig # fig2dev -L gif archoak.fig > xxx.gif What I got: sh: giftopnm: command not found images/1500.gif: Bad GIF format fig2dev: error while converting image. Command used: (ppmquant 256 /tmp/f2d157.ppm | ppmtogif) 2> /tmp/f2d157.err Messages resulting: sh: ppmquant: command not found sh: ppmtogif: command not found I giftopnm, ppmquant, ppmtogif should be provided by netpbm package but after doing: # dnf install netpbm I got the same result I will investigate it more deeply next week. Well after help from Hans I managed to reproduce the scenario. We discovered a missing dependency. I included it and rebuilt the package in rawhide. http://koji.fedoraproject.org/koji/taskinfo?taskID=15706267 Do you still demand fixing in F23/F24? I'm on F23, and won't be on F24 till F25 is released. About December for F24 install. transfig-3.2.6-2.fc25 has been pushed to the Fedora 25 testing repository.

Created attachment 1196049 [details] archoak.fig $ fig2dev -L gif archoak.fig > xxx.gif libpng error: invalid file gamma in png_set_gamma images/km-1635.png: Bad PNG format It was good in Fedora 9 to around 21 or 22. Now the picture of Kyocera KM-1635 is gone! $ xfig archoak.fig shows that it is there. So xfig is fine.
