Hi,

I'm workingwith 422 and 420 YCC planes, and would like to composite one on another with an alpha channel. Looking at the AlphaComp call, it looks like the use of a real alpha channel is only supported for 4 channel interleaved images, is that correct? Is there any way to composite using 2 single channel images and a seperate alpha channel plane?

Thanks,
Peter

Hi,

the function also support plane format: 8u_AP4R. Will that be useful?

Thanks,
Chao
