YCoCgToSBGR
Converts a YCoCg image to the 48-bit BGR image.
Syntax
Case 1: Conversion to 3-channel image
IppStatus ippiYCoCgToSBGR_16s_P3C3R(const Ipp16s* pYCC[3], int yccStep, Ipp16s* pBGR, int bgrStep, IppiSize roiSize);
IppStatus ippiYCoCgToSBGR_32s16s_P3C3R(const Ipp32s* pYCC[3], int yccStep, Ipp16s* pBGR, int bgrStep, IppiSize roiSize);
Case 2: Conversion to 4-channel image
IppStatus ippiYCoCgToSBGR_16s_P3C4R(const Ipp16s* pYCC[3], int yccStep, Ipp16s* pBGR, int bgrStep, IppiSize roiSize, Ipp16s aval);
IppStatus ippiYCoCgToSBGR_32s16s_P3C4R(const Ipp32s* pYCC[3], int yccStep, Ipp16s* pBGR, int bgrStep, IppiSize roiSize, Ipp16s aval);

Parameters
pYCC |
Array of pointers to the source image ROI in each plane. |
yccStep |
Distance in bytes between starts of consecutive lines in the source image. |
pBGR |
Pointer to the destination image ROI. |
bgrStep |
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 YCoCg image pYCC to the 48-bit BGR image pBGR according to the following formulas:
R = Y + Co - Cg
G = Y + Cg
B = Y - Co - Cg
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. |
ippStsNullPtrErr |
Indicates an error condition if one of the specified pointers is NULL. |
