Computes the size of the external buffer for the FilterBoxBorder function.
IppStatus ippiFilterBoxBorderGetBufferSize (IppiSize roiSize, IppiSize maskSize, IppDataType dataType, int numChannels, int* pBufferSize);
ippi.h
Headers: ippcore.h, ippvm.h, ipps.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib
roiSize |
Maximum size of the destination image ROI. |
maskSize |
Size of the filter mask, in pixels. |
dataType |
Data type of the image. Possible values are ipp8u, ipp16u, ipp16s, or ipp32f. |
numChannels |
Number of channels in the image. Possible values are 1, 3, or 4. |
pBufferSize |
Pointer to the size of the external work buffer. |
The ippiFilterBoxBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterBoxBorder function. The result is stored in the pBufferSize parameter.
For an example on how to use this function, see the code example provided with the ippiFilterBoxBorder function description.
ippStsNoErr |
Indicates no error. |
ippStsSizeErr |
Indicates an error when roiSize is negative, or equal to zero. |
ippStsMaskSizeErr |
Indicates an error when mask has an illegal value. |
ippStsDataTypeErr |
Indicates an error when dataType has an illegal value. |
ippStsNumChannelsError |
Indicates an error when numChannels has an illegal value. |
