ippStsRoiShiftMatrixErr
This status is tied to matrix and ROI addressing. The ROI shift must describe a valid displacement in the underlying element grid; a negative shift or one that is not divisible by the element size cannot be mapped safely.
It is most often caused by mixing byte-based pitch arithmetic with element-based offsets, or by reusing a shift computed for a different sample type.
Diagnostic focus
- Check the data type size used when computing the ROI shift.
- Verify that the shifted ROI still describes elements, not partial bytes inside an element.
- Compare the shift with the step/stride values passed to the same primitive.
