BGRToCbYCr422
Converts 32-bit per pixel BGR image to 16-bit per pixel CbYCr image.
Syntax
IppStatus ippiBGRToCbYCr422_8u_AC4C2R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Domain Dependencies
Headers: ippcore.h, ippvm.h, ipps.h, ippi.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib, ippi.lib
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 destination image ROI. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination 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 the four-channel gamma-corrected B'G'R' image pSrc to the two-channel Cb'Y'Cr' image pDst according to the same formulas as the function ippiRGBToYCbCr does. The function ippiBGRToCbYCr422 uses 4:2:2 sampling format for the converted image. An alpha-channel information is lost.
An CbYCr image has the following sequence of bytes: Cb0Y0Cr0Y1, Cb1Y2Cr1Y3, ... .
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 has a field with a zero or negative value. |
