NvBufferTransform_Filter_Smart

I am looking at the MMAPI samples and there is this enum:
NvBufferTransform_Filter_Smart

What on earth does it do?

The documentation simply says “transform filter smart”. Not very helpful. :-(

Hi,
NvBufferTransform_Filter_Smart selects one of the actual filter modes based on the scaling ratio.

I got emailed a more detail reply so you must have edited your post. Is the info I received by email correct?

Hi,
It is not 100% correct. The detail is private. Sorry I cannot give more information.
