NAME
xpmtoppm - convert an X11 pixmap into a portable pixmap
SYNOPSIS
xpmtoppm
[--alphaout={alpha-filename,-}]
[-verbose]
[xpmfile]
DESCRIPTION
Reads an X11 pixmap (XPM version 1 or 3) as input. Produces a PPM
file as output.
OPTIONS
I --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
R --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
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.
