CopyManaged
Copies pixel values between two images in accordance with the specified type of copying.
Syntax
IppStatus ippiCopyManaged_8u_C1R(const Ipp8u* pSrc, int srcStep, Ipp8u* pDst, int dstStep, IppiSize roiSize, int flags);

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:
|
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:
When flags is set to IPP_TEMPORAL_COPY, the function is identical to the ippiCopy_8u_C1R function.
When flags is set to IPP_NONTEMPORAL_STORE, the processor uses non-temporal store instructions. Copying is performed without caching the data of the destination image.
When flags is set to IPP_NONTEMPORAL_LOAD, the processor uses non-temporal load instructions.
To achieve better performance, align data to 64-byte boundary.
