Class InkDot

java.lang.Object
  ch.claudio.pen.InkDot

All Implemented Interfaces:

java.io.Serializable

public class InkDot
extends java.lang.Object
implements java.io.Serializable

Stores the data for a single Ink point

Note: This class measures time with millisecond precision. This is enough with the Sahara digitizer which delivers point information as 5 byte blocks at a speed of 9600 bit/s and is thus limited to 240 points per second.
