Y Cb Cr alpha compositing

Y Cb Cr alpha compositing

pvonkaenel's picture

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,
