CbYCr422ToYCbCr422
Converts 4:2:2 CbYCr image to 4:2:2 YCbCr image.
Syntax
IppStatus ippiCbYCr422ToYCbCr422_8u_C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters
| pSrc | Pointer to the source image ROI. | 
| srcStep | Distance in bytes between starts of consecutive lines in the source image. | 
| pDst | Pointer to the ROI in the pixel-order destination image. Array of pointers to the ROI in each plane of the planar destination image. | 
| dstStep | Distance in bytes between starts of consecutive lines in the destination image. Array of distance values for the destination image planes. | 
| roiSize | Size of the ROI in pixels, its width should be multiple of 2. | 
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 4:2:2CbYCr two-channel image pSrc to the 4:2:2 YCbCr two-channel or three-plane image pDst (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats”). The source image has the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb2, ... . Two-channel destination image has different sequence of samples: Y0, Cb0, Y1, Cr0, Y2, Cb1, Y3, Cr1, Y4, ....
Return Values
| ppStsNoErr | Indicates no error. Any other value indicates an error. | 
| ippStsNullPtrErr | Indicates an error condition if any of the specified pointers is NULL. | 
| ippStsSizeErr | Indicates an error condition if roiSize.width is less than 2. |
