16 This program is part of Netpbm(1).

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.

24 In addition to the options common to all programs based on libnetpbm
25 (most notably -quiet, see
26 Common Options ⟨index.html#commonoptions⟩ ), ximtoppm recognizes the
27 following command line option:

29 You can abbreviate any option to its shortest unique prefix.

34 ximtoppm creates a PGM file containing the transparency channel
35 values in the input image. If the input image doesn't contain a
36 transparency channel, the alpha-filename file contains all zero
37 (transparent) transparency values. If you don't specify
38 --alphaout, ximtoppm does not generate a transparency file, and
39 if the input image has a transparency channel, ximtoppm simply
40 discards it.
41
42 If you specify - as the filename, ximtoppm writes the trans‐
43 parency output to Standard Output and discards the image.
44
45 Actually, an Xim image can contain an arbitrary fourth channel
46 -- it need not be a transparency channel. ximtoppm extracts any
47 fourth channel it finds as described above; it doesn't matter if
48 it is a transparency channel or not.

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