ippStsStepErr
The step value describes how to advance from one row, vector segment, plane row or block row to the next. An invalid step can make otherwise valid pointers unsafe.
Most bugs involve using width instead of stride, using elements instead of bytes, or passing a step that is smaller than the active ROI.
Diagnostic focus
- Check the unit used by the specific primitive for step arguments.
- Verify the step is large enough for width, channels and sample size.
- Compare source and destination steps; their constraints may differ.
