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

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

IppStatus ippiHLSToBGR_8u_AP4C4R(const Ipp8u* const pSrc[4], int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

IppStatus ippiHLSToBGR_8u_P3C3R(const Ipp8u* const pSrc[3], int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize);

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.

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

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

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.
