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 starts of consecutive lines in 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 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 instruction

Description

The function ippiCopyManaged is declared in the ippi.h file. It operates with ROI (see Regions of Interest in Intel IPP).

This function copies data from a source image ROI pSrc to the destination image ROI pDst. The parameter flags specifies the type of copying that the function performs. When flags is set to IPP_TEMPORAL_COPY, the function is identical to the function ippiCopy_8u_C1R. When flags is set to IPP_NONTEMPORAL_STORE, the processor uses non-temporal store instructions, and operation is performed without caching the data of the destination image.

To achieve maximum performance, align data to the 64-byte boundary.

Optimization Notice

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error or a warning.

ippStsNullPtrErr

Indicates an error condition one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error condition if roiSize has a field with a zero or negative value.
