From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-2 i686) Description of problem: ImageMagick 5.2.7 (incl. in RH7.1) seems to have a bug in it's XPM file generation. I'm not an expert in the format, but looking at XPMs generated with RH6.1's version, one difference seems to be that convert is emitting files with 2 extra (hex) bytes per color, ie: ==> under7.1.xpm <== /* XPM */ static char *magick[] = { /* columns rows colors chars-per-pixel */ "54 54 256 2", " c #341b3840", ". c #3c3a0e40", [...] vs. ==> under6.1.xpm <== /* XPM */ static char *magick[] = { /* columns rows colors chars-per-pixel */ "54 54 256 2", " c #341b38", ". c #3c3a0e", "X c #383c18", "o c #352f12", "O c #37312a", "+ c #0e3217", [...] Use of convert's colordepth flags does not seem to have any effect on the image file emitted ("-depth 8" or "-depth 16"). How reproducible: Always Steps to Reproduce: 1. Get an image file (I've tried both GIF and JPG) 2. Under RH6.1, run "convert -geom 54x54 <image> under6.1.xpm" (optional, but can illustrate the difference..) 3. Under RH7.1, run "convert -geom 54x54 <image> under7.1.xpm" 4. Under RH7.1 try to use xpmroot (a libXpm program) to place your xpm image(s) on your X backround ("xpmroot <file>"). XPMs generated by the convert distributed with 7.1 won't be successfully read. Actual Results: % xpmroot under7.1.xpm Couldn't allocate required colors [image not displayed on X backround] The C function XpmReadFileToPixmap(..) returns -2 (XpmFileInvalid, see xpm.h). Expected Results: File displayed on X backround (xpm file generated with older convert works under RH7.1). Additional info: X is running at 15bpp (yes, fifteen.. Riva 128 card). This is a clean RH7.1 install, no LD_LIBRARY_PATH settings, etc.
