man xwdtopnm (Commandes) - convert a X11 or X10 window dump file into a portable anymap
NAME
xwdtopnm - convert a X11 or X10 window dump file into a portable anymap
SYNOPSIS
xwdtopnm [xwdfile]
DESCRIPTION
Reads a X11 or X10 window dump file as input. Produces a portable anymap as output. The type of the output file depends on the input file - if it's black & white, a pbm file is written, else if it's grayscale a pgm file, else a ppm file. The program tells you which type it is writing.
Using this program, you can convert anything on an X workstation's screen into an anymap. Just display whatever you're interested in, do an xwd, run it through xwdtopnm, and then use pnmcut to select the part you want.
BUGS
I haven't tested this tool with very many configurations, so there are probably bugs. Please let me know if you find any.
