ippStsWtOffsetErr
Wavelet filtering uses offset and phase-like parameters to align filter taps with transformed samples. An invalid offset means the transform state does not match the expected filter layout.
Check the wavelet filter specification and boundary handling before assuming the source data is corrupt.
Check these details for ippStsWtOffsetErr
- Offset value relative to filter length.
- Forward and inverse transform state compatibility.
- Boundary-extension mode used with the same filter.

Interpreting the result
This result is Intel IPP status -35. AllStat describes it as “Invalid offset value for wavelet filter.”. The decisive context is the exact IPP routine and overload, because status names are shared across image, signal, codec, cryptography, and data-compression domains with different parameter contracts.
Developer checks
- Record the full function name, library version and CPU dispatch, source and destination types, ROI or vector length, step values, scale factor, and every state/specification object passed to the call.
- Validate the result parameter group before changing buffers: initialization routines often establish constraints inherited by later processing calls.
- use ippGetStatusString for logging but branch on the numeric IppStatus value; localized or wrapper text is not a stable program contract.
Retrying this result with unchanged arguments normally reproduces the same validation failure. Rebuild the affected IPP state when configuration changed, verify buffer bounds and alignment, and isolate the smallest call that still returns the status.
