Parameters
- pSrcY
- Pointer to the ROI in the luminance plane of the source image.
- srcYStep
- Distance in bytes between starts of consecutive lines in the luminance plane of the source image.
- pSrcCbCr
- Pointer to the ROI in the interleaved chrominance plane of the source image.
- srcCbCrStep
- Distance in bytes between starts of consecutive lines in the interleaved chrominance plane of 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 source and destination 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
two-plane source image
pSrc
to the 4:2:0 three-plane image
pDst
. The first plane of the 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
has the following order of pointers:
Y
-plane,
Cr
-plane,
Cb
-plane (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 isNULL.
- ippStsSizeErr
- Indicates an error condition if any field of theroiSizeis less than 2.
