ximtoppm - convert an Xim file to a PPM image
This program is part of
ximptoppm reads an Xim file as input and produces a PPM
image as output. The Xim toolkit is included in the contrib tree of
the X.V11R4 release.
You can abbreviate any option to its shortest unique prefix.
ximtoppm creates a PGM file containing the transparency channel
values in the input image. If the input image doesn't contain a
transparency channel, the alpha-filename file contains all zero
(transparent) transparency values. If you don't specify --alphaout,
ximtoppm does not generate a transparency file, and if the input
image has a transparency channel, ximtoppm simply discards it.
If you specify - as the filename, ximtoppm writes the
transparency output to Standard Output and discards the image.
Actually, an Xim image can contain an arbitrary fourth channel --
it need not be a transparency channel. ximtoppm extracts any fourth
channel it finds as described above; it doesn't matter if it is a
transparency channel or not.

the transparency output file.
