NAME
       rledither - Floyd Steinberg dither an image to the given	colors.

SYNOPSIS
       rledither  [  -e	 edge_factor  ]	[ -l nchan length ] -{tf} mapfile [ -o
       outfile ] [ infile ]

DESCRIPTION
       This program accepts an RLE(5) file and a file of colormap entries, and
       dithers the image to those colors.  Edge	enhancement is also performed,
       if specified.

OPTIONS
       -e edge_factor
	      An edge_factor of	zero means no edge enhancement (the  default).
	      A	value of 1.0 looks pretty good for most	images.

       -l nchan	length
	      Specifies	the number of channels in the colormap,	and the	number
	      of entries in each channel.  The default is 3  channels  of  256
	      entries, which is	appropriate for	an eight bit color display.

       -{tf} mapfile
	      The  mapfile  must  contain  at least nchan*length values	in the
	      range 0 to 255.  The -t flag causes mapfile to be	read as	R G  B
	      R	 G B R G B...  The -f flag implies the entries are listed as R
	      R	R... G G G... B	B B...

       -o outfile
	      If specified, the	output will be written to this file.  If  out-
	      file is "-", or if it is not specified, the output will be writ-
	      ten to the standard output stream.

       infile The input	will be	read from this file.  If infile	is "-"	or  is
	      not  specified,  the  input will be read from the	standard input
	      stream.

BUGS
       It should read colormaps	from RLE files,	too.  For the moment, edit the
       output from rlehdr -m.
