YCbCr444ToBGRLS

Creates an YCbCr image from 444 MCU and converts it to the BGR color model.

Syntax

IppStatus ippiYCbCr444ToBGRLS_MCU_16s8u_P3C3R(const Ipp16s* pSrcMCU[3], Ipp8u* pDstBGR, int dstStep);

Parameters

pSrcMCU	Array of 3 pointers to the source image blocks.
pDstBGR	Pointer to the destination image ROI.
dstStep	Distance in bytes between starts of consecutive lines in the destination image.

Description

The function ippiYCbCr444ToBGRLS_MCU is declared in the ippj.h file. It operates with ROI (see Regions of Interest in Intel IPP). This function creates YCbCr 8x8 image from 444 MCU and converts it to the BGR format using the same formulas as the ippiYCbCrToRGB_JPEG function for computing B, G, and R component values.

Additionally, this function converts data from the signed Ipp16s range [-128..127] to the unsigned Ipp8u range [0..255] performing level shift operation (by adding 128).

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsStepErr	Indicates an error condition if dstStep has a zero or negative value.
