Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance in bytes between starts of consecutive lines in the source image.
- pDst
- Pointer to the ROI in the pixel-order destination image. Array of pointers to the ROI in each plane of the planar destination image.
- dstStep
- Distance in bytes between starts of consecutive lines in the destination image. Array of distance values for the destination image planes.
- roiSize
- Size of the ROI in pixels, its width should be multiple of 2.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the
4:2:2
CbYCr
two-channel image pSrc
to the 4:2:2 YCbCr
two-channel or three-plane image pDst
(see Table “Pixel-Order Image Formats”
and Table “Planar Image Formats”
). The source image has the following sequence of samples: Cb0
, Y0
, Cr0
, Y1
, Cb1
, Y2
, Cr1
, Y3
, Cb2
, ... . Two-channel destination image has different sequence of samples: Y0
, Cb0
, Y1
, Cr0
, Y2
, Cb1
, Y3
, Cr1
, Y4
, ....Return Values
- ppStsNoErr
- 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 2.
