rlenoise - Add random noise to an image
rlenoise [ -n amount
] [ -o outfile ] [ infile ]
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.
- 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.
