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.
