FilterMaxBorderGetBufferSize, FilterMinBorderGetBufferSize

Compute the size of the work buffer for the maximum/minimum filter.

Syntax

IppStatus ippiFilterMaxBorderGetBufferSize(IppiSize dstRoiSize, IppiSize maskSize, IppDataType dataType, int numChannels, int* pBufferSize);

IppStatus ippiFilterMinBorderGetBufferSize(IppiSize dstRoiSize, IppiSize maskSize, IppDataType dataType, int numChannels, int* pBufferSize);

Parameters

dstRoiSize	Size of the destination ROI, in pixels.
maskSize	Size of the filter kernel.
dataType	Data type of the source and destination images.
numChannels	Number of channels in the image. Possible values are 1, 3, or 4.
pBufferSize	Pointer to the size, in bytes, of the external buffer.

Description

The ippiFilterMaxBorderGetBufferSize and ippiFilterMinBorderGetBufferSize functions compute the size, in bytes, of the external work buffer for the ippiFilterMaxBorder and ippiFilterMinBorder functions, respectively. The result is stored in the pBufferSize parameter.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error when pBufferSize is NULL.
ippStsSizeErr	Indicates an error when dstRoiSize has a field with a zero or negative value.
ippStsMaskSizeErr	Indicates an error when maskSize is less than, or e qual to zero.
ippStsDataTypeErr	Indicates an error when dataType has an illegal value.
ippStsNumChannelErr	Indicates an error when numChannels has an illegal value.
