GNOME Bugzilla – Bug 524618
PNM format support outdated
Last modified: 2008-10-30 20:11:45 UTC
Sample file is at http://www.logic.at/prolog/problem.ppm (this is from an Emacs user's bug report for the same problem in Emacs - the GIMP bug was noticed when I tried to view the same image in GIMP as a reference). This file appears to conform to the current PPM specification at http://netpbm.sourceforge.net/doc/ppm.html which was updated in 2000 to increase the maximum color value from 255 to 65535. But GIMP refuses to display the image, stating "PNM: Invalid maximum value".
