Hello,
I'm trying to use AlphaComp function and AlphaPremul function to blend some images,
but I can't understand the exact meaning and use of alphaType parameter in AlphaComp functions.
There are image buffers A and B in 32bit RGBA and I used ippiAlphaPremul_8u_AC4IR function to buffer A.
I want to composite A into B, so I think I should use ippiAlphaComp_8u_AC1R function to blend the image.
Then how do I call this functions with alphaType parameter? (and other params too)
Can I get some sample codes about this function?
Thanks in advance,

Thanks for your reply. I read that thread but..
Which I want to know is how to combine AlphaComp and AlphaPremul function.
In AlphaComp function, there are alphaType parameter.
What is difference of ippiAlphaOver value and ippiAlphaOverPremul values?
Should I use AlphaPremul'ed buffer to pSrc1 or pSrc2?
