YCrCb422ToRGB

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

Syntax

Case 1: Operation on pixel-order data

IppStatus ippiYCrCb422ToRGB_8u_C2C3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Case 2: Conversion from pixel-order to planar data

IppStatus ippiYCrCb422ToRGB_8u_C2P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep, IppiSize roiSize);

pSrc	Pointer to the source image ROI for pixel-order image. An array of pointers to ROI in each separate source planes for planar images.
srcStep	Distance in bytes between starts of consecutive lines in the source image.
pDst	Pointer to the ROI in the destination pixel-order image. An array of pointers to ROI in each planes of the destination planar image.
dstStep	Distance in bytes between starts of consecutive lines in the destination image.
roiSize	Size of the source and destination ROI in pixels.

The function ippiYCrCb422ToRGB is declared in the ippcc.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts the Y'Cr'Cb' image pSrc, packed in 4:2:2 sampling format (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats” for more details) to the 24-bit gamma-corrected R'G'B' image pDst according to the same formulas as the function ippiYCbCrToRGBdoes. The output R'G'B' 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 is NULL.
ippStsSizeErr	Indicates an error condition if roiSize has a field with a zero or negative value.
