Tablet (Built-in Patch) in Controller, Device

Tablet

This patch returns the current state of the tablet pointing device.

The pen position is expressed in units in the Quartz Composer coordinates system. The pen tilt on the X and Y axes is normalized to the [-1.0,1.0] range and the pen pressure is normalized to the [0,1] range.

Note that this patch does not read the tablet state directly but is dependent on the proper information being passed to the composition. This information may not always be available, depending on the environment in which Quartz Composer is running.
