ResizeLinearInit

Initializes the specification structure for image resizing with the linear interpolation method.

Syntax

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

Supported values for mod:

8u

16u

16s

32f

IppStatus ippiResizeLinearInit_64f(IppiSize srcSize, IppiSize dstSize, IppiResizeSpec_64f* pSpec);

Platform-aware function

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

Threading layer (TL) function

IppStatus ippiResizeLinearInit_LT(IppiSizeL srcSize, IppiSizeL dstSize, IppDataType dataType, 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.

Description

This function initializes the specification structure for the resize algorithm with the linear interpolation method. To calculate the size of the specification structure, 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 if:
  • width or height of the source or destination image is negative

  • the source image size is less than the size of a 2x2 linear filter

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 or TL functions).

ippStsNumChannelErr

Indicates an error if numChannel has an illegal value.
