CbYCr422ToRGB

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

Syntax

IppStatus ippiCbYCr422ToRGB_8u_C2C3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

Parameters

pSrc	Pointer to the source image ROI.
srcStep	Distance in bytes between starts of consecutive lines in the 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

Description

The function ippiCbYCr422ToRGB is declared in the ippcc.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function converts the Cb'Y'Cr' image pSrc, packed in the 4:2:2 sampling format, to the 24-bit gamma-corrected R'G'B' image pDst according to the same formulas as the function ippiYCbCrToRGB does.

A CbYCr image has the following sequence of bytes: Cb0Y0Cr0Y1, Cb1Y2Cr1Y3, ... .

The output R'G'B' values are saturated to the range [0..255].

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.
