ResizeAntialiasingLinearInit

Initializes the specification structure for image resizing with antialiasing using linear interpolation.

Syntax

IppStatus ippiResizeAntialiasingLinearInit(IppiSize srcSize, IppiSize dstSize, IppiResizeSpec_32f* pSpec, Ipp8u* pInitBuf);

64f equivalent function

IppStatus ippiResizeAntialiasingLinearInit_64f(IppiSize srcSize, IppiSize dstSize, IppiResizeSpec_64f* pSpec, Ipp8u* pInitBuf);

Platform-aware function

IppStatus ippiResizeAntialiasingLinearInit_L(IppiSizeL srcSize, IppiSizeL dstSize, IppDataType dataType, IppiResizeSpec* pSpec, Ipp8u* pInitBuf);

Threading layer (TL) function

IppStatus ippiResizeAntialiasingLinearInit_LT(IppiSizeL srcSize, IppiSizeL dstSize, IppDataType dataType, Ipp32u numChannels, IppiResizeSpec_LT* pSpec, Ipp8u* pInitBuf);

Parameters

srcSize

Size of the source image, in pixels.

dstSize

Size of the destination image, in pixels.

dataType

Data type of the image. Supported values: ipp8u, ipp16u, ipp16s, ipp32f, ipp64f.

numChannels

Number of image channels. Possible values: 1, 3, or 4.

pSpec

Pointer to the specification structure for the resize filter.

pInitBuf

Pointer to the temporary buffer for initialization of the linear filter.

Description

This function initializes the IppiResizeSpec_32f structure for the resize operation with antialiasing using the linear interpolation method. Note, that ippiResizeAntialiasingLinearInit_64f will initialize the IppiResizeSpec_64f structure.

Before using these functions, calculate the size of the temporary buffer and specification structure using the ippiResizeGetSize function with the antialiasing parameter equal to 1.

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 if 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).

ippStsDataTypeErr

Indicates an error if dataType has an illegal value.
