NAME
rletoraw - Convert RLE file to raw RGB form.
SYNOPSIS
rletoraw [ -a ] [ -[Ns] ] [ -r ] [ -f header-size ] [ -t
trailer-size ] [ -l left-scanline-pad ] [ -p scanline-pad [
-o outfile ] [ infile ]
DESCRIPTION
This program converts an RLE(5) image to a raw RGB form.
The output file is normally a stream of pixels (RGBRGB...),
in left-to-right, bottom-to-top order (this can be changed
with the -N or -s flags). The width and height of the input
image will be printed on the standard error stream.
OPTIONS
-a If specified, an alpha channel will be written to the
output file. This is the last output channel, unless
-r is specified, in which case it will be the first.
-N If specified, the output will be written in a non-
interleaved order. I.e., all the red pixels will be
written first, then all the green pixels, etc.
-s If specified, the output will be written in a
scanline-interleaved order. I.e., all the red pixels
for a scanline will be written, followed by all the
green pixels for the scanline, etc. The options -N and
-s are mutually exclusive.
-r Reverse the order of the channels in the output. I.e.,
output will be written ABGR instead of RGBA.
-f header-size
A header of this many zero bytes will be written to the
output file.
-t trailer-size
A trailer of this many zero bytes will be written after
the output file.
-l left-scanline-pad
The left (beginning) of each scanline will be padded
with this many zero bytes.
-p left-scanline-pad
The right (end) of each scanline will be padded with
this many zero bytes.
-o outfile
If specified, the output will be written to this file.
If outfile is "-", or if it is not specified, the

output will be written 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
Basically handles input files with 1 or 3 channels (plus
alpha). Only the first channel of a 2 channel image will be
written.
The header, trailer, and pad options are of dubious utility.
