ResizeNearestInit

Initializes the specification structure for image resizing with the nearest neighbor interpolation method.

Syntax

IppStatus ippiResizeNearestInit_<mod>(IppiSize srcSize, IppiSize dstSize, IppiResizeSpec_32f* pSpec);

Supported values for mod:

16u

16s

32f

Platform-aware function

IppStatus ippiResizeNearestInit_L(IppiSizeL srcSize, IppiSizeL dstSize, IppDataType dataType, IppiResizeSpec* pSpec);

Threading layer (TL) function

IppStatus ippiResizeNearestInit_LT(IppiSizeL srcSize, IppiSizeL dstSize, IppDataType dataType, Ipp32u numChannels, IppiResizeSpec_LT* pSpec);

Parameters

srcSize	Size, in pixels, of the source image.
dstSize	Size, in pixels, of the destination image.
dataType	Data type of the image. Supported values: ipp8u, ipp16u, ipp16s, ipp32f, ipp64f.
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 nearest neighbor interpolation method. To calculate the size of the specification structure object, call the ippiResizeGetSize function.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsNoOperation	Indicates a warning when width or height of the image is equal to zero.
ippStsSizeErr	Indicates an error when width or height of the source or destination image is negative.
ippStsDataTypeErr	Indicates an error if dataType has an illegal value.
ippStsExceededSizeErr	Indicates an error If width or height of the source or destination image exceeds 33554431 (0x1FFFFFF) (only for platform-aware and TL functions).
