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 ROI in pixels, its width should be multiple of 4, its height should be multiple of 2.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function converts the
4:1:1
planar
source image pSrc
(see
Table “Planar
Image Formats”
) to the 4:2:0
planar
image pDst
. Both source
and destination images can be three- or two-plane. Three-plane images has the
following order of pointers: Y
-plane,
Cb
-plane, Cr
-plane (see Table “Planar
Image Formats”
). Two-plane images contain 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 ifroiSize.widthis less than 4 orroiSize.heightis less than 2.
