I really thought Jamie added all of that a long time ago. I know I had versions with all (or most) of the blend modes. Obviously, shaders make it kind of obsolete, so I probably never used the modes after 2006 or so.

Hello,
i don't know if this is the right place to write, sorry if don't.
I'm working in a project with PD/Gem and i need more blending methods than the original Alpha object has. I've modified slightliy the file alpha.cpp (see atachment) and recompiled Gem. Simply i've add the different OpenGL blending mehods to the switch in the function funmess(). Some are working in mi system (Debian Wheezy), others are the same output than GL_ONE. I like specially GL_ONE_MINUS_SRC_COLOR, it doesn't saturate the bright pixels like GL_ONE_MINUS_SRC_ALPHA does.
My question: Is there any reason to not include different alpha blending methods? the modification i've made is very simple and obvious, so i'm thinking about why not had made before... do i have lost something?
Regards and sorry for my english...

Hello,
You can use the object [GEMglBlendFunc].
yes, but i don't see any reason not to include it in the alpha object. cheers c
