This class is used to implement shape interface. It also presents geometric path that is constructed from:
  • Lines
  • Cubic Curves
  • Quadratic


This class supports 3 constructors which creates GeneralPath. These constructors are supported by class along with default winding rule i.e. WIND_NON_ZERO, specified initial coordinate capacity and winding rule i.e. WIND_NON_ZERO or WIND_EVEN_ODD

How to determine interior of a path is specified by using the winding rule.
Java Code:
public void Paint (Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    ...
}
Call new GeneralPath() for creation of empty GeneralPath. Then segments are added to shape, by these methods.

  • moveTo(float x, float y) –Current point of the path is moved to the given point
  • lineTo(float x, float y) –line segment is added to the current path
  • quadTo(float ctrlx, float ctrly, float x2, floaty2) –To the current path, quadratic curve segment is added.
  • curveTo(float ctrlx1, float ctrly1, float ctrlx2, float ctrly2, float x3, floaty3) – To the current path, cubic curve segment is added.
  • closePath() – Current path is closed.
