Number of channels in the images. Possible value is 1.
- pBufferSize
-
Pointer to the size, in bytes, of the external work buffer.
Description
This function calculates the size of the temporary buffer for the ippiLineSuppression function.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error when pBufferSize is NULL.
- ippStsSizeErr
-
Indicates an error in the following cases:
when roiSize is less than, or equal to zero
when avgWndSize is equal to zero
- ippStsMaskSizeErr
- Indicates an error when filterMask has an illegal value.
- ippStsDataTypeErr
- Indicates an error when dataType has an illegal value.
- ippStsNumChannelsErr
- Indicates an error when numChannels has an illegal value.
