Hi Bill,

Thanks for the ref. I had already found that code though. However, what I'm looking for right now are alpha-blending ops.

None of the functions that are found in app/paint-funcs/paint-funcs-generic.h seem to make use of the alpha channel in their calculation. None of them seem to be one of the Porter-Duff operations. But since gimp has a layer mode that seems to take into account alphas, I'm wondering where the code for that is.
