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 function
converts 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.
