Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in 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 ROI in pixels, its width should be multiple of 4.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function converts the
4:2:2
CbYCr
two-channel image pSrc
to the 4:1:1
YCbCr
three-plane image pDst
.
The source image has the following sequence of samples: Cb0
, Y0
, Cr0
, Y1
, Cb1
, Y2
, Cr1
, Y3
, Cb2
, ... . The
destination image has the following order of pointers: Y
-plane, Cb
-plane, Cr
-plane (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 ifroiSize.widthis less than 4.
