Expand Color Palette Table (CPT) Support about gridfour

[gwlucastrig]

I am considering the addition of a package called org.gridfour.imaging to store utilities related to the production of images. If I do, I will probably move the color-palette-table package to a new location org.gridfour.image.cpt.

Code that addresses this issue is included in the Gridfour Core 1.0.2 release now available via the Maven Central Repository or (as always) through Github. You may read the Javadoc at The Gridfour Application Notes Page.

I will be leaving this issue open until I prepare some example application code.

The latest version of the CPT API is available in the Core module of the Gridfour API.

The CPT classes depend on the Java AWT. In the future, we may move them to a separate package in order to remove dependencies on the AWT from the Core package. This change will allow the core Gridfour API to operate under Android OS (which does not support the Java AWT).
