Computes the size of the work buffer for the Sobel Vertical filter.
IppStatus ippiFilterSobelVertBorderGetBufferSize (IppiSize dstRoiSize, IppiMaskSize mask, IppDataType srcDataType, IppDataType dstDataType, int numChannels, int* pBufferSize);
IppStatus ippiFilterSobelVertBorderGetBufferSize_T (IppiSize dstRoiSize, IppiMaskSize mask, IppDataType srcDataType, IppDataType dstDataType, int numChannels, int* pBufferSize);
ippi.h
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 ippiFilterSobelVertBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterSobelVertBorder 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 ippiFilterSobelVertBorder function description.
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. |
