NAME

       xpmtoppm - convert an X11 pixmap into a portable pixmap

SYNOPSIS

       xpmtoppm [--alphaout={alpha-filename,-}] [-verbose] [xpmfile]

DESCRIPTION

       Reads an X11 pixmap (XPM version 1 or 3) as input.  Produces a PPM file as output.

OPTIONS

       --alphaout=alpha-filename
	      xpmtoppm	creates a PBM file containing the transparency mask for the image.  If the input image doesn't contain transparency infor-
	      mation, the alpha-filename file contains all white (opaque) alpha values.  If you don't specify --alphaout, xpmtoppm does not gener-
	      ate an alpha file, and if the input image has transparency information, xpmtoppm simply discards it.

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

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

       --verbose
	      xpmtoppm prints information about its processing on Standard Error.

LIMITATIONS

       The  support  to  XPM  version  3 is limited. Comments can only be single lines and there must be for every pixel a default colorname for a
       color type visual.
