Why a separate function SuperSampling?

[Thomas_Jensen1]

Since the functions Resize() and ResizeSqrPixel() can do interpolation using super sampling, why does IPP 6.1B contain a separate function SuperSampling()?

Is that function faster?
Does it have a smaller memory footprint?

The PDF does not indicate any of this.

I ask because I would like to know if it is worthwhile to make a special-case for when super sampling an image.

Hello,

separable functions allow you to minimize amount of memory used for internal buffers. This particular function was created byIPP customers request.
