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  trans‐
              parency information, xpmtoppm simply discards it.

              If you specify - as the filename, xpmtoppm writes the alpha out‐
              put 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.
