Surface and alpha change

Hi

I'm new here .

I'm actually trying to create a 2D application (painting), with layers.

So I'm looking for informations about surface and alpha transformation, like :
- surface_add_alpha_from surface : change, or add the alpha of a surface A, into a surface B (the alpha will be A*B ?)
- surface_change_alpha : copy, paste, cut

Is it possible to do that with GM ?

Thank you very much for all your informations, and happy good year .
