About blending mode.

Question

Is there any way to use the blending mode implemented in AfterEffects with the plug-in?
I would like to know if there is an API such as AEGP, etc., as it would be troublesome to implement it myself.
If there is no API, I would appreciate it if you could provide me with a page where the blending mode calculation formulas are compiled.

yes, there is such api.a few of the CompositeSuite callbacks performs compositing with a specified transfer mode. the simplest of which is AEGP_TransferRect, and it takes a PF_CompositeMode arguemnt.  as for the math of the transfer modes,  there's no code in the sdk being compiled that can show you how they're calculated, but here's a very good explanations on most of them:https://en.wikipedia.org/wiki/Blend_modesmeybe if you google hard enough you'll also find code samples or each, but the wiki page explains the math pretty well. &#128578;if i recall correctly, there's also such a page by adobe explaining asll the rest of the transfer modes.
