How to convert from packed to planar RGB using IPP?

[levicki]

I have a project which already uses IPP for other stuff, and now I wonder if IPP has functions to convert from packed RGB (or RGBA) to planar RGB (or RGBA)?

In other words:

src0 = RGB RGB RGB ...

dst0 = RRR ...
dst1 = GGG ...
dst2 = BBB ...
[dst3 = AAA ...]

Are there such functions or should I just write a loop?

Hello,
Can you can ippiCopy_ function? some functions like (ippiCopy_8u_C3P3R) may help.

Thanks,
Chao
