ASC_CDL
The ASC_CDL operator represents a color transform in the American Society of Cinematographers' Color
Decision List format (*.ccc or *.cdl).
An ASC CDL transform consists of a slope-offset-power (SOP) function applied individually to each of the
RGB channels, followed by a saturation function applied equally to all channels.
It is an Autodesk extension to the Academy/ASC XML color transform format.
Introduced
Version 1.3.

Description (page 1332). Optional, any number.
SOPNode (page 1356). Optional, no more than one. If absent, no slope-offset-power function is applied.
SatNode (page 1359). Optional, no more than one. If absent, no saturation function is applied.
DynamicParameter (page 1362). Optional, no more than one. The param attribute must be set to
"DEFAULT_LOOK".

style Determines the formula applied by the operator.
NOTE The equations assume that the input and output bit-depths are floating-point. For integers, the values are
normalized to [0.0, 1.0]. In other words, the slope, offset, power, and saturation values stored in the CTF file do
not depend on the input and output bit depths.
NOTE The luma weights assume that the image uses the primaries specified by Rec. 709 (for example, HD and
sRGB).
