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  ⟨index.html#commonoptions⟩  ), 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.
