18 ximptoppm reads an Xim file as input and produces a PPM image as out‐
19 put. The Xim toolkit is included in the contrib tree of the X.V11R4
20 release.

29 ximtoppm creates a PGM file containing the transparency channel
30 values in the input image. If the input image doesn't contain a
31 transparency channel, the alpha-filename file contains all zero
32 (transparent) transparency values. If you don't specify
33 --alphaout, ximtoppm does not generate a transparency file, and
34 if the input image has a transparency channel, ximtoppm simply
35 discards it.
36
37 If you specify - as the filename, ximtoppm writes the trans‐
38 parency output to Standard Output and discards the image.
39
40 Actually, an Xim image can contain an arbitrary fourth channel
41 -- it need not be a transparency channel. ximtoppm extracts any
42 fourth channel it finds as described above; it doesn't matter if
43 it is a transparency channel or not.

45 See pamcomp(1) for one way to use the transparency output file.
