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

       In addition to the options common to all programs based on libnetpbm (most notably  -quiet,  see   Common
       Options ), ximtoppm recognizes the following command line option:

       You can abbreviate any option to its shortest unique prefix.

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

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

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

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