xpmtoppm - convert an X11 pixmap into a PPM image
SYNOPSIS
xpmtoppm [--alphaout={alpha-filename,-}] [-verbose] [xpm
file]
DESCRIPTION
Reads an X11 pixmap (XPM version 1 or 3) as input. Pro
duces a PPM file as output.
OPTIONS
--alphaout=alpha-filename
xpmtoppm creates a PBM file containing the trans
parency 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, xpm
toppm simply discards it.
If you specify - as the filename, xpmtoppm writes
the alpha output to Standard Output and discards
the image.
See pnmcomp(1) for one way to use the alpha output
file.
--verbose
xpmtoppm prints information about its processing on
Standard Error.
LIMITATIONS
The support to XPM version 3 is limited. Comments can only
be single lines and there must be for every pixel a
default colorname for a color type visual.
