Parameters
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. |
Description
The ippiFilterSobelHorizBorderGetBufferSize function computes the size, in bytes, of the external work buffer needed for the ippiFilterSobelHorizBorder function. The result is stored in the pBufferSize parameter.
For an example on how to use this functions, see the code example provided with the ippiFilterSobelHorizBorder 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. |
