Method Detail

transformColormap

protected GridSampleDimension transformColormap(int[] ARGB,
                                                int band,
                                                GridSampleDimension sampleDimension,
                                                ParameterValueGroup parameters)

Transforms the supplied RGB colors.

Specified by:

transformColormap in class IndexColorOperation

Parameters:

ARGB - Alpha, Red, Green and Blue components to transform.

band - The band number, from 0 to the number of bands in the image -1.

sampleDimension - The sample dimension of band band.

parameters - The user-supplied parameters.

Returns:

A sample dimension identical to sampleDimension except for the colors. Subclasses may conservatively returns sampleDimension.
