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 isNULL.
- ippStsContextMatchErr
- Indicates an error if pointer to the spec structure is invalid.
- ippStsBorderErr
- Indicates an error ifborderhas an illegal value.
