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.
