Public bug reported:

I'm trying to capture the screen to a png file, with the following
command:

xwd -root -display :0 | xwdtopnm | pnmtopng > file.png

The output file is a valid png file, but it's a garbled picture.

By doing the following diagnostic steps, xwdtopnm was determined to be
the problem:

xwd -root -display :0 > test.xwd ; gimp test.xwd   ===> picture looks good
xwdtopnm < test.xwd > test.pnm  ; gimp test.pnm ===> gimp reports "PNM Image Message: Unsupported maximum value."
pnmtopng < test.pnm > test.png ; gimp test.png ===> gimp loads a garbled picture

file test.xwd  ===> file.xwd: XWD X Window Dump image data, "xwdump",
3840x1080x24

pnmtoxwd < test.pnm > test2.xwd ; gimp test2.xwd  ===> gimp loads a
garbled picture

Hopefully you can fix the glitch in xwdtopnm easily!

Thanks!
