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 im‐
	      age 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.	xim‐
	      toppm extracts any fourth channel it finds as described above; it doesn't matter if it is a transparency chan‐
	      nel or not.

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