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.
