how to implement this function?

Gorggg commented 3 years ago

I would think this could be implemented someday by having a texture containing alpha values that are multiplied with the source. This is at least how AmanithVG seems to implement it, although I can't be sure because it is closed-source. Implementing it this way would also have the effect of making ShivaVG require 2 texture units, but for most modern hardware that shouldn't be an issue.
