SYNOPSIS

DESCRIPTION

18       This program is part of Netpbm(1).
19
20       xpbtoppm reads an X11 pixmap (XPM version 1 or 3) as input and produces
21       a PPM image as output.

OPTIONS

25       --alphaout=alpha-filename
26              xpmtoppm creates a PBM file containing the transparency mask for
27              the  image.   If  the  input  image doesn't contain transparency
28              information, the alpha-filename file contains all white (opaque)
29              alpha  values.   If  you don't specify --alphaout, xpmtoppm does
30              not generate an alpha file, and if the input  image  has  trans‐
31              parency information, xpmtoppm simply discards it.
32
33              If you specify - as the filename, xpmtoppm writes the alpha out‐
34              put to Standard Output and discards the image.
35
36              See pamcomp(1)foronewaytouse the alpha output file.
37
38              xpmtoppm can't handle a line longer than 8K  characters  in  the
39              the  XPM  input.   If an input line exceeds this limit, xpmtoppm
40              quits with an error message to that effect.  Before Netpbm 10.30
41              (October 2005), the limit was 2K.
42
43
44       --verbose
45              xpmtoppm  prints  information  about  its processing on Standard
46              Error.

LIMITATIONS

52       The recogized XPM version 3 features are limited.  Comments can only be
53       single  lines and there must be for every pixel a default colorname for
54       a color type visual.
