Parameters
- numChannels
- Number of channels in the image. Possible values are 1 or 3.
- lenLow
- Length of the lowpass filter.
- anchorLow
- Anchor position of the lowpass filter.
- lenHigh
- Length of the highpass filter.
- anchorHigh
- Anchor position of the highpass filter.
- pSpecSize
- Pointer to the computed size of theippiWTFwdspecification structure, in bytes.
- pBufSize
- Pointer to the computed size of the work buffer, in bytes.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error when any of the specified pointers isNULL.
- ippStsNumChannlesErr
- Indicates an error whennumChannelshas an illegal value.
- ippStsNumChannlesErr
- Indicates an error whenlenLoworlenHighis less than 2.
- ippStsAnchorErr
- Indicates an error whenanchorLoworanchorHighis less than zero.
