ResizeGetBorderSize

Computes the size of possible borders for the resize transform.

Syntax

Case 1: Interpolation with single precision

IppStatus ippiResizeGetBorderSize_<mod>(const IppiResizeSpec_32f* pSpec, IppiBorderSize* borderSize);

Supported values for mod:

8u

16u

16s

32f

Case 2: Interpolation with double precision

IppStatus ippiResizeGetBorderSize_64f(const IppiResizeSpec_64f* pSpec, IppiBorderSize* borderSize);

Case 3: Processing images with platform-aware functions

IppStatus ippiResizeGetBorderSize_L(const IppiResizeSpec* pSpec, IppiBorderSize* borderSize);

Case 4: Processing images with threading layer (TL) functions

IppStatus ippiResizeGetBorderSize_LT(const IppiResizeSpec_LT* pSpec, IppiBorderSize* borderSize);

Parameters

pSpec

Pointer to the spec structure for the resize filter.

borderSize

Size in pixels of necessary borders.

Description

This function computes the size of the source image ROI that is used by the corresponding resize transform and is out of the processing boundaries. The pSpec parameter defines the resize algorithm parameters. Prior to using the ippiResizeGetBorderSize function, you need to initialize the pSpec parameter by calling one of the following functions: ippiResizeNearestInit, ippiResizeLinearInit, ippiResizeCubicInit, ippiResizeLanczosInit, and ippiResizeSuperInit.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error if one of the specified pointers is NULL.

ippStsContextMatchErr

Indicates an error if pointer to the spec structure is invalid.

ippStsBorderErr

Indicates an error if border has an illegal value.
