!!NAME


xpmtoppm - convert an X11 pixmap into a PPM image
!!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 information, the ''alpha-filename''
file contains all white (opaque) alpha values. If you don't
specify __--alphaout__, __xpmtoppm__ does not generate
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.
