NAME
       ppmtowinicon  -	convert 1 or more portable pixmaps into a
       Windows .ico file

SYNOPSIS
       ppmtowinicon [-andpgms] [-output output.ico] [ppmfiles...]

DESCRIPTION
       Reads  one  or more portable pixmaps as input.  Produces a
       Microsoft Windows .ico file as output.

       A Windows icon contains 1 or  more  images,  at	different
       resolutions and color depths.

       Microsoft recommends including at least the following for
       mats in each icon.

       16 x 16 - 4 bpp

       32 x 32 - 4 bpp

       48 x 48 - 8 bpp

       Default I/O is STDIN/STDOUT.

OPTIONS
       -andpgms
	      If this option is given, every other file	 is  read
	      as  an  alpha  mask  to  be  used	 by  windows  for
	      transparancy data for the previous  image.   (These
	      are  set to blank by default).  The alpha mask is a
	      PGM image, where any value less than  or	equal  to
	      the  maxval means transparent, and anything greater
	      than the maxval means opaque.  Note  that	 as  with
	      all  Netpbm  programs,  you may use a PBM file here
	      and it will be used as if it  were  the  equivalent
	      PGM.

       -output output.ico
	      File  to write.  By default, the icon is written to
	      stdout.
