NAME
xpmtoppm - convert an X11 pixmap to a PPM image
SYNOPSIS
xpmtoppm
[--alphaout={alpha-filename,-}]
[-verbose]
[xpmfile]
DESCRIPTION
This program is part of Netpbm.
xpbtoppm reads an X11 pixmap (XPM version 1 or 3) as input
and produces a PPM image as output.
OPTIONS
- --alphaout=alpha-filename
- xpmtoppm creates a PBM file containing the transparency
mask for the image. If the input image doesn't contain transparency
information, the alpha-filename file contains all white
(opaque) alpha values. If you don't specify --alphaout,
xpmtoppm does not generate an alpha file, and if the input
image has transparency information, xpmtoppm simply discards
it.
If you specify - as the filename, xpmtoppm writes the
alpha output to Standard Output and discards the image.
See pamcomp for one way to use
the alpha output file.
- --verbose
-
xpmtoppm prints information about its processing on Standard Error.
LIMITATIONS
The recogized XPM version 3 features are limited. Comments can
only be single lines and there must be for every pixel a default
colorname for a color type visual.
