NAME

rlenoise - Add random noise to an image

SYNOPSIS

rlenoise [ -n amount ] [ -o outfile ] [ infile ]

DESCRIPTION

Rlenoise adds uniform random noise to an image. The peak-to-peak amplitude of the noise can be specified with the -n flag, the default value is 4. This program may be useful for trying to deal with quantization in an output device, if you are able to trade spatial resolution for color resolution, and you don't have a good characterization of the quantization function.

OPTIONS

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.
