BGRToYCrCb420
Converts a BGR image to the YCrCb image with 4:2:0 sampling format.
Syntax
IppStatus ippiBGRToYCrCb420_8u_C3P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);
IppStatus ippiBGRToYCrCb420_8u_AC4P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep[3], IppiSize roiSize);

Parameters
pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
An array of pointers to ROI in separate planes of the destination image. |
dstStep |
An array of distances in bytes between starts of consecutive lines in the destination image planes. |
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 planar Y'Cr'Cb' image pDst according to the same formulas as the function ippiRGBToYCbCr does. The destination image pDst has the 4:2:0 sampling format and the following order of pointers: Y-plane, Cr-plane, Cb-plane (see 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 2. |
