Name
scatter - make a scatterplot
Syntax
scatter <input1> <input2> <output>
Description
Creates a scatterplot (a two dimensional
histogram) of band 1 of the two input images.
The scatterplot is returned as an unsigned byte
image.
Restrictions
Accepts only UNS_BYTE pixels. Every
scatter update that would increase the
scatter value beyond 255 increases an
overflow counter, which is eventually
written to stderr.
