       ximtoppm - convert an Xim file into a portable pixmap

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

       Reads  an  Xim  file  as input.	Produces a portable pixmap as output.  The Xim toolkit is
       included in the contrib tree of the X.V11R4 release.

	      ximtoppm creates a PGM (portable graymap) 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 Out-
	      put 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 pnmcomp(1) for one way to use the alpha output file.

       All options can be abbreviated to their shortest unique prefix.
