FilterSeparableGetBufferSize

Computes the size of the work buffer.

Syntax

IppStatus ippiFilterSeparableGetBufferSize(IppiSize roiSize, IppiSize kernelSize, IppDataType dataType, IppDataType kernelType, int numChannels, int* pBufferSize);

IppStatus ippiFilterSeparableGetBufferSize_L(IppiSizeL roiSize, IppiSize kernelSize, IppDataType dataType, IppDataType kernelType, int numChannels, IppSizeL* pBufferSize);

IppStatus ippiFilterSeparableGetBufferSize_T(IppiSize roiSize, IppiSize kernelSize, IppDataType dataType, IppDataType kernelType, int numChannels, int* pBufferSize);

IppStatus ippiFilterSeparableGetBufferSize_LT(IppiSizeL roiSize, IppiSize kernelSize, IppDataType dataType, IppDataType kernelType, int numChannels, IppSizeL* pBufferSize);

Parameters

roiSize	Size of the image ROI in pixels.
kernelSize	Size of the rectangular kernel in pixels.
dataType	Data type of the source image. Possible values are Ipp8u, Ipp16s, Ipp16u, Ipp32f.
kernelType	Data type of the filter kernel. Possible values are Ipp16s and Ipp32f.
numChannels	Number of channels in the image. Possible values are 1, 3, and 4.
pBufferSize	Pointer to the size of the work buffer required for filtering.

Description

This function computes the size of the buffer required for filtering operations. Call this function before using the ippiFilterSeparable function.

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.
ippStsSizeErr	Indicates an error condition if kernelSize has a field with a zero or negative value.
ippStsDataTypeErr	Indicates an error condition if dataType has an illegal value.
ippStsChannelErr	Indicates an error condition if numChannels has an illegal value.
