Algorithm how to transform vector magnitude to length of arrow on the device in pixels.
| Enumerator | |
|---|---|
| MinMax | Scale vector magnitude linearly to fit in range of vectorFilterMin() and vectorFilterMax() |
| Scaled | Scale vector magnitude by factor scaleFactor() |
| Fixed | Use fixed length fixedShaftLength() regardless of vector's magnitude. |
