Package cptutils

Utilities to manipulate and translate color gradients

https://jjg.gitlab.io/en/code/cptutils

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 seaviewsensing.com/pub/cpt-city/ where thousands of
gradients can be downloaded.
