Utilities to manipulate and translate color gradients
Description
The GMT package implements colour gradients with the cpt (colour palette) file format,
and provides some tools for creating and manipulating them.The cptutils package contains
a number of additional utilities, mostly for translation to and from other formats.
The cptutils package was written to aid the construction of the cpt archive
cpt-city http://seaviewsensing.com/pub/cpt-city/ where thousands of
gradients can be downloaded.
