IPP Operations on planar data (IPP malloc for planar data)

I want to perform resize operation on planar data. Functions that
operate on planar images require an array of separate pointers (IppType* plane[3]) to
each plane as input. To do that I got sample code from manual. In this sample code how the stepBytes[] array is initialized?

int stepBytes[3];
Ipp8u* plane[3];
plane[0] = ippiMalloc_8u_C1(widthPixels, heightPixels,
&(stepBytes [0]));
plane[1] = ippiMalloc_8u_C1(widthPixels/2, heightPixels/2,
&(stepBytes [1]));
plane[2] = ippiMalloc_8u_C1(widthPixels/2, heightPixels/2,
&(stepBytes [2]));

Hi Kishore,
