ximtoppm(1)

NAME

   ximtoppm - convert an Xim file into a portable pixmap

SYNOPSIS

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

DESCRIPTION

   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.

OPTIONS

   --alphaout=alpha-filename
          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 Output 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.
