HLSToBGR

Converts an HLS image to the RGB color model.

Syntax

IppStatus ippiHLSToBGR_8u_C3P3R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[3], int dstStep, IppiSize roiSize);

IppStatus ippiHLSToBGR_8u_AC4P4R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst[4], int dstStep, IppiSize roiSize);

IppStatus ippiHLSToBGR_8u_AP4R(const Ipp8u* pSrc[4], int srcStep, Ipp8u* pDst[4], int dstStep, IppiSize roiSize);

IppStatus ippiHLSToBGR_8u_P3R(const Ipp8u* pSrc[3], int srcStep, Ipp8u* pDst[3], int dstStep, IppiSize roiSize);

Parameters

pSrc

Pointer to the ROI in the pixel-order source image. An array of pointers to ROI in each plane in the planar source image.

srcStep

Distance in bytes between starts of consecutive lines in the source image.

pDst

Pointer to the ROI in the pixel-order destination image. An array of pointers to ROI in each plane in the planar destination image.

dstStep

Distance in bytes between starts of consecutive lines in the destination image.

roiSize

Size of the source and destination ROI in pixels.

Description

This function operates with ROI (see Regions of Interest in Intel IPP).

This functionconverts the HLS image pSrc to the B'G'R' image pDst according to the same formula as the function ippiHLSToRGB does.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error.

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.
