FilterSobelNegVertBorderGetBufferSize

Computes the size of the work buffer for the Sobel vertical filter.

Syntax

IppStatus ippiFilterSobelNegVertBorderGetBufferSize (IppiSize dstRoiSize, IppiMaskSize mask, IppDataType srcDataType, IppDataType dstDataType, int numChannels, int* pBufferSize);

Include Files

ippi.h

Domain Dependencies

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

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

Parameters

dstRoiSize

Size of the destination ROI in pixels.

mask

Predefined mask of IppiMaskSize type. Possible values are ippMskSize3x3 or ippMskSize5x5.

srcDataType

Data type of the source image.

dstDataType

Data type of the destination image.

numChannels

Number of channels in the image. Possible value is 1.

pBufferSize

Pointer to the size of the external work buffer.

Description

The ippiFilterSobelVertSecondBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterSobelNegVertBorder function. The result is stored in the pBufferSize parameter.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when pBufferSize is NULL.

ippStsSizeErr

Indicates an error when dstRoiSize is negative, or equal to zero.

ippStsMaskSizeErr

Indicates an error when mask has an illegal value.

ippStsDataTypeErr

Indicates an error when srcDataType or dstDataType has an illegal value.

ippStsNumChannelsError

Indicates an error when numChannels has an illegal value.
