iwiMirror

Syntax
typedef struct _IwiMirrorParams
{
    IwiChDescriptor chDesc;
} IwiMirrorParams;
static IW_INLINE void iwiMirror_SetDefaultParams(
    IwiMirrorParams *pParams
)
IW_DECL(IppStatus) iwiMirror(
    const IwiImage         *pSrcImage,
    IwiImage               *pDstImage,
    IppiAxis                axis,
    const IwiMirrorParams  *pAuxParams,
    const IwiTile          *pTile
);
Parameters
pSrcImage
Pointer to the source image.
pDstImage
Pointer to the destination image.
axis
Mirror axis.
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
chDesc
iwiChDesc_None
Special channels processing mode.
Description
This function mirrors an image over the specified axis.
For
ippAxs45
 and
ippAxs135
axis
 values, the destination image must have a flipped size:
dstWidth
 =
srcHeight
,
dstHeight
 =
srcWidth
.
This function supports the following features:
Feature
Support
Internal threading
No
Manual tiling
Yes
IwiTile
 simple tiling
Yes
IwiTile
 pipeline tiling
No
Return Values
ippStsDataTypeErr
The
dataType
 value is illegal.
ippStsNumChannelsErr
The
channels
 value is illegal.
ippStsNotSupportedModeErr
The selected combination of parameters' values is not supported.
ippStsInplaceModeNotSupportedErr
In-place operation is not supported in tiling mode:
pSrcImage
 is equal to
pDstImage
.
ippStsNullPtrErr
At least one of the pointers is
NULL
.
ippStsNoErr
No errors.
