Parameters
pSrc
Pointer to the ROI in the pixel-order source image. Array of pointers to the ROI in each plane of the planar source image.
srcStep
Distance in bytes between starts of consecutive lines in the source image. Array of distance values for the source image planes.
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 source and destination ROI in pixels.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the
4:2:2
two-channel source image
pSrc
to the 4:2:2 three-plane image
pDst
and vice versa (see Table
“Pixel-Order Image Formats”
and Table
“Planar Image Formats”
for more details on 4:2:2 planar and pixel-order 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
of the first plane is less than 2, or
roiSize.height
is less than or equal to zero.
