FilterScharrHorizMaskBorderGetBufferSize
Computes the size of the work buffer for the Scharr Horizontal filter.
Syntax
IppStatus ippiFilterScharrHorizMaskBorderGetBufferSize (IppiSize dstRoiSize, IppiMaskSize mask, IppDataType srcDataType, IppDataType dstDataType, int numChannels, int* pBufferSize);
Include Files
ippi.h
Parameters
dstRoiSize |
Size of the destination ROI in pixels. |
mask |
Predefined mask of IppiMaskSize type. Possible value is ippMskSize3x3. |
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. |
Description
The ippiFilterScharrHorizMaskBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterScharrHorizMaskBorder 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 ippiFilterScharrHorizMaskBorder function description.
Return Values
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. |
