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. |
