iwiCopy

Syntax

typedef struct _IwiCopyParams { int reserved; } IwiCopyParams;
static IW_INLINE void iwiCopy_SetDefaultParams( IwiCopyParams *pParams )
IW_DECL(IppStatus) iwiCopy( const IwiImage *pSrcImage, IwiImage *pDstImage, const IwiImage *pMaskImage, const IwiCopyParams *pAuxParams, const IwiTile *pTile );
Parameters
pSrcImage
Pointer to the source image.
pDstImage
Pointer to the destination image.
pMaskImage
Pointer to the mask image.
pAuxParams
Pointer to the auxiliary parameters structure. If
NULL
, default parameters are used.
pTile
Pointer to the
IwiTile
structure for tiling. If
NULL
, the whole image is processed.
Auxiliary Arguments
Argument
Default Value
Description
reserved
0
Reserved value
Description
This function copies image data from the source to destination image with masking.
If the mask image is
NULL
, the function performs regular copying. Otherwise, the function copies source image pixel values only if the corresponding values of the mask image pixels are non-zero.
This function supports the following features:

Return Values
ippStsNumChannelsErr
Channels value is illegal.
ippStsDataTypeErr
Data type is illegal.
ippStsSizeErr
Values of the
size
fields are illegal.
ippStsNullPtrErr
At least one of the pointers (except
pTile
) is
