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);

Include Files

ippi.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

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:

To achieve better performance, align data to 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 when one of the specified pointers is NULL.

ippStsSizeErr

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