This includes room for the alpha channel (yay). FYI, component byte order in Qrgb (most- to least-significant) is A-R-G-B.

map [0,N-1] into colorpixels, where N is the current colormap size The values are returned as unsigned integers in their respective array.

Tip: The choice of what type to use should be guided by the number of graphics bitplanes available; For most systems with 8-bit color, casacore::uChar is optimal; Some systems with 12 bits per pixel with an alpha channel may require using the uLong;

Warning: casacore::uChar type may not have enough bits to hold the pixel index on some high-end graphics systems

Warning: casacore::uShort type may not have enough bits to hold the pixel index on some high-end graphics systems
