Hi Marco,
for the case of rotation by 90 degrees you may prefer to use ippiMirror functions which should be much faster than general ippiRotate.
And note, if your frame is 8-bit per channel you need to use 8u functions not 16u.

Hello Vladimir,
Thanks for the tips. Mirror functions only help when it's 180 degrees.
Unfortunatelly there is no rotate 8U_C2.
I guess I have to convert it to 24 bit, and then rotate.

Oh, yes, you are correct. I mean ippiTranspose function, but this does not work with sub-sampled image formats (like YUV422 or 420).

Vladimir
