Created attachment 400717 [details] patch based on upstream Description of problem: xwdtopnm produces incorrect ppm output for xwd dump of an rdesktop screen Version-Release number of selected component (if applicable): netpbm-10.35.58.x How reproducible: always Steps to Reproduce: 1. Connect to a Windows XP system using rdesktop: rdesktop 192.168.1.100 2.Get an xwd dump of the rdesktop screen by running the following command and selecting the rdesktop screen with the mouse: xwd -screen -frame > out.xwd 3. Convert the xwd dump to ppm format using xwdtopnm xwdtopnm out.xwd > out.ppm 4. View both images: display out.xwd display out.ppm Actual results: out.ppm has incorrect colors Expected results: out.ppm show show the correct image Additional info: * xwd, when run on the rdesktop window, generates a DirectColor image with 24bpp depth and BGR layout and MSB bit order. * The header on the xwd image however claims that the image has an RGB layout and LSB bit order., which leads the image colors to be read incorrectly by xwdtopnm * ImageMagick and Gimp read the image correctly, hence this is a bug in xwd which has been fixed upstream in netpbm 10.35.64 , thanks to Siddhesh for tracking this down, along with the patch
