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:

8u

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).
