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
The Intel® Integrated Performance Primitives (Intel® IPP) library contains functions that are more highly optimized for Intel microprocessors than for other microprocessors. While the functions in the Intel® IPP library offer optimizations for both Intel and Intel-compatible microprocessors, depending on your code and other factors, you will likely get extra performance on Intel microprocessors. While the paragraph above describes the basic optimization approach for the Intel® IPP library as a whole, the library may or may not be optimized to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel® 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. Intel recommends that you evaluate other library products to determine which best meets your requirements.

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.
