# 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.

## Outputs
|
|
|
|
| Name | Type | Description |

|
| tilted | DATA_FIELD | Field with tilt applied or removed |
|

## Controls
|
|
|
|
| Name | Type | Default | Description |
|
|
|------|------|---------|-------------|
|
|
| slope_x | FLOAT | 0.0 | Slope along the x axis in data units per physical unit (e.g. nm/um) |
|
|
| slope_y | FLOAT | 0.0 | Slope along the y axis in data units per physical unit (e.g. nm/um) |
|
|
| mode | dropdown | subtract | 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.
