Hello All
A have some quastion about some fuction from IPP such as
ippiConvValid_32f_C3R.

I have tryed convolution matrix of image with kernel 3x3
Arr{
0,0,0
0,1,0
0,0,0
}

I have used the following code:

ippiConvValid_32f_C3R.
(Ipp32f*)temp.DataPtr(), temp.Step(), temp.Size(),
(Ipp32f*)Arr.DataPtr(), 3, Arr.Size(),
(Ipp32f*)tempdst.DataPtr(), tempdst.Step());

I use black and white image
I should get the same image after convolution
But i get image with much green color.

May be you know what i did wrong

Hello,

step is number of bytes between adjacent lines. Remember about that when you work with data other than Ipp8u.
