YCbCr422ToRGB

Converts 16-bit per pixel YCbCr image to 24-bit per pixel RGB image.

Syntax

Case 1: Operation on pixel-order data

IppStatus ippiYCbCr422ToRGB_JPEG_8u_C2C3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Case 2: Operation on planar data

IppStatus ippiYCbCr422ToRGB_JPEG_8u_P3C3R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiYCbCr422ToRGB_JPEG_8u_P3C4R(const Ipp8u* pSrc[3], int srcStep[3], Ipp8u* pDst, int dstStep, IppiSize roiSize, Ipp8u aval);

pSrc	Pointer to the source image ROI. Array of pointers to ROI in each plane of the planar source image.
srcStep	Distance in bytes between starts of consecutive lines in planes of the source image. Array of distance values in each plane of the planar 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.

The function ippiYCbCr422ToRGB_JPEG is declared in the ippj.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts an YCbCr image pSrc, packed in 4:2:2 sampling format (see Figure “Different JPEG Sampling Formats” for more details) to the RGB image pDst according to the same formulas as the function ippiYCbCrToRGB_JPEG does. The output RGB values are saturated to the range [0..255].

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if pSrc or pDst pointer is `NULL`.
ippStsSizeErr	Indicates an error condition if roiSize has a field with zero or negative value.
