Parameters
pSrc
Array of pointers to the ROI in each plane of the source image.
srcStep
Array of distances in bytes between starts of consecutive lines in each plane of the source image.
pDst
Pointer to the ROI in the pixel-order destination image. Array of pointers to the ROI in each plane of the planar destination image.
dstStep
Distance in bytes between starts of consecutive lines in the destination image. Array of distance values for the destination image planes.
roiSize
Size of the ROI in pixels, height and width should be multiple of 2.
Description
This function converts the
4:2:0
YCrCb
three-plane image
pSrc
to the
4:2:2
YCbCr
three-plane or two-channel image
pDst
(see Table
“Pixel-Order Image Formats”
and Table
“Planar Image Formats”
).
This function operates with ROI (see Regions of Interest in Intel IPP).
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 any field of the
roiSize
is less than 2.
