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 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, height and width should be multiple of 2.
Description
This function converts the
4:2:0
YCrCb
three-plane image pSrc
to the 4:2:2
YCbCr
three-plane or two-channel image pDst
(see Table “Pixel-Order Image Formats”
and Table “Planar Image Formats”
). This function operates with ROI (see Regions of Interest in Intel IPP).
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.
