No ippiMirror_32f?

Hi,

It's me again :-) I was trying to use ippiMirror in a substitute function for ippiCopySymmetricBorder. My data is all floats, so I simply tried ippiMirror_32f_C1R. No luck! That function doesn't exist. Why is that?

I solved it by using ippiMirror_32s_C1R. After all, mirroring is mirroring, and 32 bits is 32 bits.

Hi Koen,

you are absolutely correct by using ippiMirror_32s for Ipp32f data types. There is no any specific in copying four-bytes elements (does not matter integer of single precision float) so no reason in separate function.

Vladimir

Hi Vladimir,

Thanks for the reply. I'll continue to use ippiMirror_32s for Ipp32f data types. It is confusing, though, because in other cases, such as ippiCopy, both _32s and _32f versions are available, while I assume them to be the same as well.
