xpmtoppm - convert an X11 pixmap into a PPM image


SYNOPSIS

       xpmtoppm  [--alphaout={alpha-filename,-}] [-verbose] [xpm­
       file]


DESCRIPTION

       Reads an X11 pixmap (XPM version 1 or 3) as  input.   Pro­
       duces a PPM file as output.


OPTIONS

       --alphaout=alpha-filename
              xpmtoppm  creates  a PBM file containing the trans­
              parency 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, xpm­
              toppm 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.
