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
