edu.stanford.hci.r3.pattern.coordinates.conversion
Class FlexiblePatternCoordinateConverter

java.lang.Object
  edu.stanford.hci.r3.pattern.coordinates.conversion.FlexiblePatternCoordinateConverter

All Implemented Interfaces:

PatternCoordinateConverter

public class FlexiblePatternCoordinateConverter
extends java.lang.Object
implements PatternCoordinateConverter

This coordinate converter will automatically move to wherever the anchor point is set, and will take on the width and height of its associated region. The anchor will be set to the first sample that comes in, if it is not otherwise set. Thus, this pattern coordinate converter can be easily changed at runtime. Be careful if you have more than one of these in your paper application, as the first one encountered may consume the event before the other one sees if (if the two regions somehow become "overlapped"). Also, if you never set your anchor point, this region may opportunistically steal pen input from another region on your sheet, if it is encountered first by the EventEngine.
