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.
