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
- Array of pointers to the ROI in each plane for a three-plane destination image.
- dstStep
- Array of distances in bytes between starts of consecutive lines in each plane for a three-plane destination image.
- pDstY
- Pointer to the ROI in the luminance plane for a two-plane destination image.
- dstYStep
- Distance in bytes between starts of consecutive lines in the luminance plane of a destination image.
- pDstCbCr
- Pointer to the ROI in the interleaved chrominance plane for a two-plane destination image.
- dstCbCrStep
- Distance in bytes between starts of consecutive lines in the chrominance plane of a destination image.
- 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
three-plane (see
Table
“Planar Image Formats”
) source image
pSrc
to the 4:2:0 two-plane image and vice versa. Two-plane image contains luminance samples
Y0
,
Y1
,
Y2
, .. in the first plane, and interleaved chrominance samples
Cb0
,
Cr0
,
Cb1
,
Cr1
,... in the second plane.
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.
