Parameters

srcSize	Size, in pixels, of the source image.
dstSize	Size, in pixels, of the destination image.
xShift	Shift value in the x direction.
yShift	Shift value in the y direction.
borderType	Type of border. Supported values: ippBorderTransp. Outer pixels are not processed.
borderVal	Not used. This parameter is applicable only to the ippBorderConst border type.
smoothEdge	Flag for edge smoothing. Supported values: 0 - transformation without edge smoothing. 1 - transformation with edge smoothing.
pSpec	Pointer to the specification structure for the resize filter.
numChannels	Number of channels. Possible values are 1, 3, and 4.

Description

This function initializes the specification structure for the resize algorithm with the super sampling interpolation method. To calculate the size of the specification structure, call the ippiResizeGetSize function.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if one of the specified pointers is NULL.
ippStsNoOperation	Indicates a warning if: - width or height of the destination image is equal to zero. - smoothing edge is on and width or height of the destination image is equal to one.
ippStsSizeErr	Indicates an error in the following cases: Indicates that one of the specified dimensions of the source image is less than the corresponding dimension of the destination image, or that the width or height of the source or destination image is negative. If the width or height of the source or destination image is negative.
ippStsExceededSizeErr	Indicates an error If width or height of the source or destination image exceeds 33554431 (0x1FFFFFF) (only for platform-aware and TL functions).
ippStsDataTypeErr	Indicates an error if dataType has an illegal value.
ippStsNumChannelsErr	Indicates an error if the number of channels is not supported.
ippStsBorderErr	Indicates an error if specified borderType is not supported.
