ippStsThreshNegLevelErr
This status is tied to thresholding primitives where the threshold level is constrained to a non-negative domain. It is more specific than a general range error.
It often appears when signed intermediate values are reused as threshold levels, or when an application converts a normalized floating-point control into an integer threshold incorrectly.
Diagnostic focus
- Inspect the level value after scaling, clamping and type conversion.
- Check whether the primitive expects absolute levels rather than signed deltas.
- For multi-channel calls, verify all channel thresholds, not just the first one.
