Rounding mode of ippiFilterBorder_16s_C1R

I need to use ippiFilterBorder_16s_C1R with ippRndZero mode. I set ippRndZero mode and some divisor in ippiFilterBorderInit_16s but the result of filtering looks as I had used ippRndNear mode.

Why is the function insensitive to the mode?

Hi Igor.

Thanks for interes to ippiFilterBorder_16s. The flag IppRoundMode roundMode is reserved and does not support ippRndZero. You can use ippiFilter_Round32s_16s_C1R instead. Correct implementation of ippRndZero will be added to next IPP release.
