Parameters
pSrc
Array of pointers to the ROI in each plane for a three-plane source image.
srcStep
Array of distances in bytes between starts of consecutive lines in each plane for a three-plane 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, its width should be multiple of 4.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the
4:1:1
three-plane image
pSrc
to the
4:2:2
two-channel or three-plane image
pDst
with different order of components. The source image has the following order of pointers:
Y
-plane,
Cb
-plane,
Cr
-plane (see Table
“Planar Image Formats”
). The three-plane destination image has the following order of pointers:
Y
-plane,
Cr
-plane,
Cb
-plane (see Table
“Planar Image Formats”
), and two-channel destination image has the following sequence of samples:
Y0
,
Cr0
,
Y1
,
Cb0
,
Y2
,
Cr1
,
Y3
,
Cb1
, ... (see Table
“Pixel-Order 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.
