convert
public java.awt.Image convert(int maxcubes)
Uses Heckbert's median-cut algorithm to divide the color space defined by "hist" into "maxcubes" cubes. The centroids (average value) of each cube are are used to create a color table. "hist" is then updated to function as an inverse color map that is used to generate an 8-bit image.
