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
