Claim 11:
12. The computer-implemented method of claim 11, wherein performing the median cut algorithm on the gradient color value array comprises:
determining a smallest three-dimensional box within color space that contains all sampling points in the gradient color value array; and
dividing the smallest three-dimensional box into a plurality of defined regions based on the median cut algorithm;
wherein dividing the smallest three-dimensional box into the plurality of defined regions comprises:
sorting the sampling points within the smallest three-dimensional box along a longest axis of the smallest three-dimensional box;
dividing the smallest three-dimensional box into two regions at a median of sorted sampling points; and
applying sorting and dividing to the two regions until the smallest three-dimensional box has been divided into the plurality of defined regions.
