NAME
       gencolor	- output a pattern of byte values

SYNOPSIS
       gencolor	[-r#] [-p -b] [-{sS} squaresize] [-{wW}	width] [-{nN} height]
		[val1 ... valN]

DESCRIPTION
       gencolor	repeats	a pattern of up	to 8192	8-bit values on	its standard
       output. The values, which range from 0 to 255, are taken	either from
       the command line, or in binary (as stored in a .bw or .pix file)	from
       standard	input; if the values are not supplied, a single	value of 0,
       for black, is used. The -r flag can be used to specify the number of
       times to	repeat the given pattern, the default being infinity (unless
       any other "-" options are used -- see below). This program is useful
       for producing a given grey value	or color. Note that gencolor will
       refuse to write its output to a window; you must	redirect the output to
       a file.

       -p and -b are used to specify pix file and bw file, respectively.  -w
       (or -W) indicates the width; -n (or -N) indicates the height; width and
       height are set to the same value	using -s (or -S). By default, a	pix
       file of size 512x512 is assumed;	however, use of	-r overrules use of
       any other "-" options.

EXAMPLE
       gencolor	-r512 0	255 0 >	foo.pix

       will output 512 "green" pixels (0 255 0 being used as RGB values).

       gencolor	-r1 0 255 0 | gencolor -r512 > foo.pix

       will do the same	as above, using	standard input instead of having the
       values on the command line.
