BGRToYCbCr422
Converts 24-bit per pixel BGR image to 16-bit per pixel YCbCr image.
Syntax
Case 1: Operation on pixel-order data
IppStatus ippiBGRToYCbCr422_8u_C3C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);
IppStatus ippiBGRToYCbCr422_8u_AC4C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);
Case 2: Conversion from pixel-order to planar data
IppStatus ippiBGRToYCbCr422_8u_C3P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);
IppStatus ippiBGRToYCbCr422_8u_AC4P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

Parameters
pSrc |
Pointer to the source mage ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Pointer to the ROI in the destination pixel-order image. An array of pointers to ROI in each planes of the destination planar image. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination pixel-order image. An array of distances in bytes for each plane of the destination planar image. |
roiSize |
Size of the source and destination ROI in pixels. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts a three- or four-channel gamma-corrected B'G'R' image pSrc to the two-channel or three-planes Y'Cb'Cr' image pDst according to the same formulas as the function ippiRGBToYCbCr does. The difference is that ippiBGRToYCbCr422 uses the 4:2:2 sampling format (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats” for more details).
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsNullPtrErr |
Indicates an error condition if pSrc or pDst is NULL. |
ippStsSizeErr |
Indicates an error condition if roiSize.width is less than 2 or roiSize.height is less than 1. |
