Tilt
Apply or remove a linear tilt (planar slope) from a DATA_FIELD. The tilt is defined by slope values in data units per physical unit along the x and y directions. Equivalent to Gwyddion's tilt.c module.

Operation mode: subtract (remove tilt) or add (apply tilt) |
Notes
- In subtract mode the specified planar slope is removed from the field, useful for compensating known sample tilt.
- In add mode the slope is added, useful for simulating a tilted surface or restoring a previously subtracted tilt.
- The slope values are in data-unit per physical-unit (e.g. nm/um). The actual z-change per pixel depends on the field's physical pixel size.
- For leveling an unknown tilt, consider Plane Level instead, which automatically fits and removes the best-fit plane.
