FilterBorderGetSize

Computes the size of the filter specification structure and the size of the work buffer.

Syntax

IppStatus ippiFilterBorderGetSize (IppiSize kernelSize, IppiSize dstRoiSize, IppDataType dataType, IppDataType kernelType, int numChannels, int* pSpecSize, int* pBufferSize);

Parameters

kernelSize	Size of the rectangular kernel in pixels.
dstRoiSize	Maximal size of the destination image ROI (in pixels).
dataType	Data type of the source image. Possible values are ipp8u, ipp16u, ipp16s, ipp32f, or ipp64f.
kernelType	Data type of the filter kernel. Possible values are ipp16s, ipp32f, or ipp64f.
numChannels	Number of channels in the image. Possible values are 1, 3, or 4.
pSpecSize	Pointer to the size of the filter specification structure.
pBufferSize	Pointer to the size of the work buffer required for filtering.

Description

This function operates with ROI.

This function computes the size of the filter specification structure pSpec and the size of the buffer required for filtering operations. Call this function before using the ippiFilterBorderInit function.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when kernelSize has a field with a zero or negative value, or if dstRoiSize is less than 1.
ippStsDataTypeErr	Indicates an error when dataType or kernelType has an illegal value.
ippStsChannelErr	Indicates an error when numChannels has an illegal value.
