ResizeYUV422GetSize

Computes sizes of the spec structure and the external buffer for YUY2 resize transform initialization.

Syntax

IppStatus ippiResizeYUV422GetSize(IppiSize srcSize, IppiSize dstSize, IppiInterpolationType interpolation, Ipp32u antialiasing, Ipp32s* pSpecSize, Ipp32s* pInitBufSize);

Include Files

ippi.h

Domain Dependencies

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

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

Parameters

srcSize

Size of the source image in pixels.

dstSize

Size of the destination image in pixels.

interpolation

Interpolation method. Supported values are ippNearest and ippLinear.

antialiasing

Antialiasing method.

pSpecSize

Pointer to the size in bytes of the spec structure.

pInitBufSize

Pointer to the size in bytes of the temporal buffer.

Description

This function computes sizes of the spec structure and the external buffer that are required for one of the following functions depending on the interpolation method parameter: ResizeYUV422NearestInit and ResizeYUV422LinearInit.

The filter sizes of the Nearest Neighbor and Linear interpolation algorithms are 2x1 and 4x2 respectively.

NOTE:

Antialiasing is currently not supported. The value for the antialiasing parameter must be equal to zero.

Return Values

ippStsNoErr

Indicates no error. Any other value indicates an error.

ippStsNullPtrErr

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

ippStsNoOperation

Indicates a warning if width or height of the image is equal to zero.

ippStsSizeErr

Indicates an error in the following cases:
  • if the source image size is less than the filter size for the chosen interpolation method,

  • if one of the calculated sizes exceeds maximum 32 bit signed integer positive value (the size of one of the processed images is too large).

ippStsSizeWrn

Indicates a warning if width of the image is odd.

ippStsInterpolationErr

Indicates an error if interpolation has an illegal value.

ippStsNoAntialiasing

Indicates a warning if the specified interpolation method does not support antialiasing.

ippStsNotSupportedModeErr

Indicates an error if the requested mode is currently not supported.
