This function is used to apply a color LUT to a monochrome or color image.
When applied to a monochrome image, each unique gray value is replaced with a 24-bit value from the color LUT for viewing purposes only. The grayscale data is not changed. When applied to a color image, each color plane is mapped independently through the corresponding plane of the colormap. This changes the color values in the image. This can effectively act as a color correcting function for images that require it.
All colormaps have 256 entries per plane. For image data greater than 8-bit (such as 16-bit gray or 48-bit color) only the most significant 8 bits are used.
