CIGAL supports several different ways of storing and displaying color information, which is necessary to accommodate the various different display devices and file formats.

Pixel intensities can be coded as one of the following:

   8-bit grayscale    - value is intensity (0 black -> 255 white)
   8-bit pseudocolor  - value is index to a 3 byte (RGB) color table
  16-bit color        - value is color as RRRRRGGGGGGBBBBB (binary)
  24-bit color        - value is color as RRGGBBh (hexadecimal)
  32-bit color        - same as 24-bit (high byte ignored)
