ResizeYUV420SuperInit

Initializes the spec structure for the NV12 resize transform by interpolation with the super sampling algorithm.

Syntax

IppStatus ippiResizeYUV420SuperInit(IppiSize srcSize, IppiSize dstSize, IppiResizeYUV420Spec* pSpec);

Include Files

ippi.h

Domain Dependencies

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

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

Parameters

srcSize

Size in pixels of the source image.

dstSize

Size in pixels of the destination image.

pSpec

Pointer to the spec structure for the resize filter.

Description

This function initializes the IppiResizeYUV420Spec structure for the resize algorithm using interpolation with the super sampling algorithm.

To calculate the size of the spec structure object, call the ippiResizeYUV420GetSize function.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

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

ippStsResizeNoOperation

Indicates an error if width or height of the image is equal to zero.

ippStsSizeWrn

Indicates a warning if width or height of the image is odd.

ippStsSizeErr

Indicates an error in the following cases:
  • if width or height of the image is equal to 1,

  • if one of the specified dimensions of the source image is less than the corresponding dimension of the destination image,

  • if width or height of the source or destination image is negative.
