NAME
       ximtoppm - convert an Xim file to a PPM image


SYNOPSIS
       ximtoppm

       [--alphaout={alpha-filename,-}] [ximfile]


DESCRIPTION
       This program is part of Netpbm(1)

       ximptoppm reads an Xim file as input and produces a PPM image as
       output.  The Xim toolkit is included in the contrib tree of the X.V11R4
       release.


OPTIONS
       You can abbreviate any option to its shortest unique prefix.



       --alphaout=alpha-filename
              ximtoppm creates a PGM file containing the alpha channel values
              in the input image.  If the input image doesn't contain an alpha
              channel, the alpha-filename file contains all zero (transparent)
              alpha values.  If you don't specify --alphaout, ximtoppm does
              not generate an alpha file, and if the input image has an alpha
              channel, ximtoppm simply discards it.

              If you specify - as the filename, ximtoppm writes the alpha
              output to Standard Output and discards the image.

              Actually, an Xim image can contain an arbitrary fourth channel
              -- it need not be an Alpha channel.  ximtoppm extracts any
              fourth channel it finds as described above; it doesn't matter if
              it is an alpha channel or not.

              See pamcomp(1)
               for one way to use the alpha output file.
