CbYCr422ToBGR
Converts 16-bit per pixel CbYCr image to four channel BGR image.
Syntax
IppStatus ippiCbYCr422ToBGR_8u_C2C4R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize, Ipp8u aval);

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. |
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 Cb'Y'Cr' image pSrc, packed in 4:2:2 sampling format, to the four channel gamma-corrected B'G'R' image pDst according to the same formulas as the function ippiYCbCrToRGB does.
A CbYCr image has the following sequence of bytes: Cb0Y0Cr0Y1, Cb1Y2Cr1Y3, ... .
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 has a field with a zero or negative value. |
