YCoCgToBGR_Rev
Converts a YCoCg-R image to the 24-bit BGR image.
Syntax
IppStatus ippiYCoCgToBGR_Rev_16s8u_P3C3R(const Ipp16s* pYCC[3], int yccStep, Ipp8u* pBGR, int bgrStep, IppiSize roiSize);
IppStatus ippiYCoCgToBGR_Rev_16s8u_P3C4R(const Ipp16s* pYCC[3], int yccStep, Ipp8u* pBGR, int bgrStep, IppiSize roiSize, Ipp8u 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-R image pYCC to the 24-bit BGR image pBGR according to the following formulas:
t = Y - (Cg >> 1)
G = Cg + t
B = t - (Co >> 1)
R = B + Co
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. |
