xpmtoppm(1)
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.
