xpmtoppm: convert an X11 pixmap into a portable pixmap
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
- --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 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.AUTHOR
