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.
- pSrcY
- Pointer to the ROI in the luminance plane for a two-plane source image.
- srcYStep
- Distance in bytes between starts of consecutive lines in the luminance plane of a source image.
- pSrcCbCr
- Pointer to the ROI in the interleaved chrominance plane for a two-plane source image.
- srcCbCrStep
- Distance in bytes between starts of consecutive lines in the interleaved chrominance 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 operates with ROI (see
Regions of Interest in Intel IPP
).
This function converts the
4:2:0
planar source image
pSrc
to the
4:2:2
image
pDst
. The source image can be two- or three-plane image (see
Table
“Planar Image Formats”
). The first plane of the two-plane source image
pSrcY
contains luminance samples
Y0
,
Y1
,
Y2
, ..., the second plane
pSrcCbCr
contains interleaved chrominance samples
Cb0
,
Cr0
,
Cb1
,
Cr1
, .... . The destination image
pDst
can be three-plane or two-channel (see
Table
“Pixel-Order Image Formats”
and
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 isNULL.
- ippStsSizeErr
- Indicates an error condition if any field of theroiSizeis less than 2.
