APPLYMAP(1)		    General Commands Manual		   APPLYMAP(1)

NAME
       applymap	- Apply	the color map in an RLE	file to	the pixel data

SYNOPSIS
       applymap	[ -l ] [ -o outfile ] [	infile ]

DESCRIPTION
       This  program  takes  the  color	map in an RLE(5) file and modifies the
       pixel values by applying	the color map to them.	If there is more  than
       one  color  channel  in the input file, the color map in	the input file
       should have the same number of channels.	 If the	input file has a  sin-
       gle  color  channel, the	output file will have the same number of color
       channels	as the color map.

       Each pixel in the input file is mapped as follows:  For a multi-channel
       input  file, a pixel in channel i is mapped as map[i][pixel] __ 8, pro-
       ducing a	pixel in output	channel	i.  The	right shift takes the  16  bit
       color  map  value  to an	8 bit pixel value.  For	a single channel input
       file, to	produce	a pixel	in output channel i is produced	from the  cor-
       responding input	pixel value as map[i][pixel] __	8.

OPTIONS
       -l     This  option  will  cause	 a  linear  (identity) color map to be
	      loaded into the output file.  Otherwise, the  output  file  will
	      have no color map.

       infile The  input will be read from this	file, otherwise, input will be
	      taken from stdin.

       -o outfile
	      If specified, output will	be written to this file, otherwise  it
	      will go to stdout.

BUGS
       If  the image data and color map	channels in the	input file do not con-
       form to the restriction stated above (N->N or 1->N)  the	 program  will
       most likely core	dump.
