IPhone Cocos2D - list of blending modes available for sprite and how to set them

Question

I am going to find a list of all the blending modes allowed by sprites on Cocos2D, but could not find it. Quartz can perform these blending modes, and I'm sure Cocos2D can do it too.

• Modenormal
• Modemultiply
• Modescreen
• Modeoverlay
• Modearken
• Modelighten
• ModeColorDodge
• ModeColorBurn
• ModeSoftLight
• Modehardlight
• ModeDifference
• ModeExclusion
• Modehue
• ModeSaturation
• Modecolor
• Modeluminosity

The only thing I could find on google was "additive", which I consider to be a screen. It is set like this:

[proxy setBlendFunc: (ccBlendFunc) { GL_SRC_ALPHA, GL_ONE }]; // example of additive blending 

I'm not even sure if this is a screen.

So, where can I find such a list and installation instructions for each of them?

thanks.

Here you will find a detailed description of OpenGL blending modes . And if you want to try, there is a wonderful visual interactive tool glBlendFunc .
