Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance, in bytes, between the starting points of consecutive lines in the destination image.
- roiSize
- Size of the image ROI in pixels.
- flags
- Specifies the type of copying. Possible values are:
- IPP_TEMPORAL_COPY- standard copying
- IPP_NONTEMPORAL_STORE- copying without caching the destination image
- IPP_NONTEMPORAL_LOAD- processor uses non-temporal load instructions
Description
This function operates with ROI.
This function copies data from a source image ROI
pSrc
to the destination image ROI
pDst
. The flags
parameter specifies the type of
copying that the function performs:- Whenflagsis set toIPP_TEMPORAL_COPY, the function is identical to theippiCopy_8u_C1Rfunction.
- Whenflagsis set toIPP_NONTEMPORAL_STORE, the processor uses non-temporal store instructions. Copying is performed without caching the data of the destination image.
- Whenflagsis set toIPP_NONTEMPORAL_LOAD, the processor uses non-temporal load instructions.
To achieve better performance, align data to 64-byte boundary.
