Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source image.
pDst
Array of pointers to the ROI in each plane of the destination image.
dstStep
Array of distances in bytes between starts of consecutive lines in the destination image planes.
roiSize
Size of the ROI in pixels, its width should be multiple of 4.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the
4:2:2
YCrCb
two-channel image
pSrc
(see Table
“Pixel-Order Image Formats”
) to the
4:1:1
YCbCr
three-plane image
pDst
(see Table
“Planar Image Formats”
).
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize.width
is less than 4.
