Computes the size of the work buffer for the Sobel Horizontal (second derivative) filter.
IppStatus ippiFilterSobelHorizSecondBorderGetBufferSize (IppiSize dstRoiSize, IppiMaskSize mask, IppDataType srcDataType, IppDataType dstDataType, int numChannels, int* pBufferSize);

Headers: ippcore.h, ippvm.h, ipps.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib
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. |
The ippiFilterSobelHorizSecondBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterSobelHorizSecondBorder function. The result is stored in the pBufferSize parameter.
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. |
