Parameters
- pSrc
- Array of pointers to the ROI in each plane of the source image.
- srcStep
- Array of distances in bytes between starts of consecutive lines in each plane of the source image.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance in bytes between starts of consecutive lines in the 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
YCrCb
three-plane image pSrc
(see Table “Planar
Image Formats”
) to the 4:2:2
CbYCr
two-channel image pDst
with the following
sequence of samples: Cb0
, Y0
, Cr0
, Y1
, Cb1
, Y2
, Cr1
, Y3
, Cb2
, ... (see Table “Pixel-Order 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.
