NAME

       ximtoppm - convert an Xim file to a PPM image



SYNOPSIS

       ximtoppm

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

       You can abbreviate any option to its shortest unique prefix.



DESCRIPTION

       This program is part of Netpbm(1).

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



OPTIONS

       --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 out-
              put 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)foronewaytouse the alpha output file.
