You can get the color table as follows:
ScalarMap rgbMap = new ScalarMap(..., Display.RGB);
. . .
ColorControl control = (ColorControl) rgbMap.getControl();
float table = control.getTable();
// now save the table with the image
I don't know enough about your file format to know how
you'd save the color table, but at least this code shows
you how to get the table information from VisAD.
