ResizeYUV420GetBorderSize

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

Syntax

IppStatus ippiResizeYUV420GetBorderSize(const IppiResizeYUV420Spec* pSpec, IppiBorderSize* borderSize);

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

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.

Note

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.
