YUVToRGB
Converts a YUV image to the RGB color model.
Syntax
Case 1: Operation on pixel-order data
IppStatus ippiYUVToRGB_<mod>(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);
Supported values for mod:
8u_C3R |
8u_AC4R |
IppStatus ippiYUVToRGB_8u_C3C4R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize, Ipp8u aval);
Case 2: Operation on planar data
IppStatus ippiYUVToRGB_8u_P3R(const Ipp8u* pSrc[3], int srcStep, Ipp8u* pDst[3], int dstStep, IppiSize roiSize);
Case 3: Conversion from planar to pixel-order data
IppStatus ippiYUVToRGB_8u_P3C3R(const Ipp8u* pSrc[3], int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters
pSrc |
Pointer to the source buffer for pixel-order data. An array of pointers to separate source color planes in case of planar data. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Pointer to the destination buffer for pixel-order data. An array of pointers to separate destination color planes in case of planar data. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. |
aval |
Constant value to create the fourth channel. |
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 Y'U'V' image pSrc to the gamma-corrected R'G'B' image pDst according to the following formulas:
R' = Y' + 1.140*V'
G' = Y' - 0.394*U' - 0.581*V'
B' = Y' + 2.032*U'
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. |
