7.7 Kodak Cineon display driver

This display driver allows you to write Kodak's Cineon files. Each channel is encoded in 10bits using a logarithmic scale (regardless of Exposure and Quantize). Such an encoding is appropriate for film recording since it is designed to cover film's recordable color range. A color encoded using the Cineon format can be much brighter than white, therefore it is recommended to use unquantized values for this display driver to avoid clipping the colors to (1,1,1).

The alpha channel is supported by this display driver but it is not guaranteed to be readable by other software. We suggest to use RGB (no alpha) for maximum portabilty.

Three parameters are recognised by this display driver:

"uniform integer setpoints[2]" [ref_white ref_black]
This sets the reference black and the reference white values. The default values are 180 for reference black and 685 for reference white;
"uniform integer ref_white" value
Only sets the reference white;
"uniform integer ref_black" value
Only sets the reference black;

An explanation of those parameters can be found in the Cineon documentations available on the web. The standard extension for a Cineon file is `.cin'.
