Rotation to Tilt

Some drawing software doesn't support rotation but almost all support tilt. Rotation can be converted cleanly into tilt.

• Tilt Multiplier (Default: 64): Tilt generally caps out at -64 to 64. Using a multiplier of 64 gives the highest precision but if you'd like a less extreme angle on brushes you can lower this.

• Rotation Degrees Offset (Default: 0): Offsets the converted tilt angle. If the angle of your brush is incorrect, change this value. You likely want 90, 180, or 270.

• Convert to unit square instead of unit circle (Default: false): Typically tilt values operate on a square but rotation is simply an angle so it could be converted to either a unit circle or unit square. In most cases you wont see any change from this option.

  Extreme tilt values such as [64, 64] are at one of the corners of the square. The same tilt value mapped to a circle is [45.25, 45.25].

  Both of these values define the same angle but the unit circle is consistent in its distance whereas the unit square gets further from the center towards the corners.
