PointUtils converts between two coordinate systems:
  • Pixel coordinate system: screen rendering/layout coordinates (unit: px)
  • EMR coordinate system: digitizer/handwriting hardware coordinates (unit: hardware units)
For background and differences between the two coordinate systems, see: Coordinate System.
