YCbCr422ToBGR
Converts a YCbCr image with 4:2:2 sampling to the BGR image.
Syntax
Case 1: Operation on pixel-order data
IppStatus ippiYCbCr422ToBGR_8u_C2C3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);
IppStatus ippiYCbCr422ToBGR_8u_C2C4R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize, Ipp8u aval);
Case 2: Conversion from planar to pixel-order data
IppStatus ippiYCbCr422ToBGR_8u_P3C3R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters
pSrc |
Pointer to the source image ROI. An array of pointers to the ROI in each separate plane of the source planar image. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. An array of such distances in bytes for each plane of the source planar 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. |
aval |
Constant value to create the fourth channel. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the Y'Cb'Cr' image pSrc with 4:2:2 sampling (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats” for more details) to the gamma-corrected B'G'R' image pDst according to the same formulas as the function ippiYCbCrToRGB does.
The output B'G'R' values are saturated to the range [0..255].
The fourth channel is created by setting channel values to the constant value aval.
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. |
