iwiCopyChannel

Syntax
class IwiCopyChannelParams: public ::IwiCopyChannelParams { public: IW_BASE_PARAMS_CONSTRUCTORS(IwiCopyChannelParams, iwiCopyChannel_SetDefaultParams) IwiCopyChannelParams() {} };
IW_DECL_CPP(IppStatus) iwiCopyChannel( const IwiImage &pSrcImage, int srcChannel, IwiImage &dstImage, int dstChannel, const IwiCopyChannelParams &auxParams = IwiCopyChannelParams(), const IwiTile &tile = IwiTile() );
Parameters
pSrcImage
Pointer to the source image.
srcChannel
Number of source image channels.
pDstImage
Pointer to the destination image.
dstChannel
Number of destination image channels.
tile
Pointer to the
IwiTile
class for tiling. If
NULL
, the whole image is processed.
Description
This function copies the selected channel from one multi-channel image to another.
Return Values
ippStsNoErr
No errors.

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.
