 Apply Colormap


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.
