I'm looking for a resource on alpha testing, alpha blending, and such. Something that talks about different blending modes, how they work, why they work, what they do. Things like that. I feel like I definitely should know this stuff by now, but I don't, so I'd like to remedy that. Thanks!

Right now I'm using SFML, but it was my impression that the information should transfer. Of course, I'm not qualified to say that, since if I was I wouldn't be asking this. Is that impression wrong?

Hmm I don't know SFML but as far as I can see it is using openGL. Perhaps you can get access directly to the openGL api, and call the
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
glEnable(GL_BLEND)
functions.

this is at least the procedure in pyglet (a python media api) but I don't know if this is usable in SFML.

Otherwise you'll have to dive into the SFML api (or get help from someone else than me)
