iwiResize

IW_DECL(IppStatus) iwiResize( const IwiImage *pSrcImage, IwiImage *pDstImage, IppiInterpolationType interpolation, const IwiResizeParams *pParams, IwiBorderType border, const Ipp64f *pBorderVal, const IwiTile *pTile );
Parameters
pSrcImage
Pointer to the source image.
pDstImage
Pointer to the destination image.
interpolation
Interpolation method. Supported values are
ippNearest
,
ippLinear
,
ippCubic
,
ippLanczos
, and
ippSuper
.
pParams
Pointer to the optional parameters structure. If
NULL
, the default parameters are used.
border
Extrapolation algorithm for out of image pixels processing. Supported values:
ippBorderConst
Values of all border pixels are set to a constant.
ippBorderRepl
Border is replicated from the edge pixels.
ippBorderMirror
Border pixels are mirrored from the source image boundary pixels.
ippBorderInMem
Border is obtained from the source image pixels in memory.
pBorderVal
Pointer to an array of values to assign to pixels of the constant border, one element of the array for each channel of the image. This parameter is applicable only to the
ippBorderConst
border type and can be
NULL
for other border types.
pTile
Pointer to the
IwiTile
structure for tiling. If
NULL
, the whole image is processed.
Description
This function performs resize oparation on a given ROI.
This function supports the following features:
Feature
Support

IwiTile
pipeline tiling
No
Return Values
ippStsNoErr
No errors.
ippStsSizeErr
Values of the
size
fields are illegal.
ippStsBorderErr
The
border
value is illegal.
ippStsDataTypeErr
The
dataType
value is illegal.
ippStsNumChannelsErr
The
channels
value is illegal.
ippStsNotEvenStepErr
The
srcStep
and/or
dstStep
value is not divisible by size of elements.
ippStsInplaceModeNotSupportedErr
In-place operation is not supported:
pSrc
is equal to
pDst
.
ippStsNotSupportedModeErr
Specified combination of parameters' values is not supported.
ippStsNoMemErr
Failed to allocate memory.
ippStsNullPtrErr
At least one of the pointers (except
pTile
and
pBorderVal
) is
NULL
.
ippStsNoOperation
Warning: width and/or height of the image is equal to zero.

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.
