Compositing Operators

Multi-Input COPs


The COP2_MultiBase class mostly manages creation of the output TIL_Sequence information, by resolving differences in input TIL_Sequence information. For example, if one input had a frame range of 1-5 frames, and the other 3-10, what should the output range be?

Because there is no 100% right answer to resolving these differences, COP2_MultiBase provides five parameters in a Merge tab to allow the user to resolve the difference.
All the work of resolving plane differences is done in COP2_MultiBase::cookSequenceInfo(). If you override this method, you should call the COP2_MultiBase version before doing anything else.

COP2_MultiBase does not implement any other dependency, image bounds or cook methods.
