ResizeYUV420GetBorderSize

Computes the size of possible borders for the NV12 resize transform.

Syntax

IppStatus ippiResizeYUV420GetBorderSize(
const IppiResizeYUV420Spec*
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 for Luma and Chroma planes. The
pSpec
parameter defines the resize algorithm parameters. Prior to using the
ippiResizeYUV420GetBorderSize
function, you need to initialize the
pSpec
parameter by calling one of the following functions:
ippiResizeYUV420LanczosInit
or
ippiResizeYUV420SuperInit
.
The returned border size is in Luma/Chroma plane pixels. This means that the chosen resize algorithm uses the returned outer size of the source image ROI for each plane.
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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors.
