Field Summary

static int	EvenOddRule Mode for filling polygons: If the winding number of an area is even, this area is filled.
static int	WindingRule Mode for filling polygons: If the winding number of an area is nonzero, this area is filled.

Fields inherited from class java.awt.Polygon

bounds, npoints, xpoints, ypoints

Constructor Summary

IlIntPolygon(int[] xpoints, int[] ypoints, int npoints)
Creates a polygon.

IlIntPolygon(int[] xpoints, int[] ypoints, int npoints, int fillRule)
Deprecated. Use the three-argument constructor. The only supported fillRule is EvenOddRule.

Method Summary

Polygon	getFillingPolygon() Returns a polygon which, when filled according to EvenOddRule, represents (approximately) this polygon.
protected int	getFillRule() Returns the mode for filling this polygon.
Enumeration	horizontalLineIntersection(int y) Intersects this polygon with a given horizontal line, and returns an enumeration of the intervals belonging to the polygon.
protected void	setFillRule(int r) Sets the mode for filling this polygon.
String	toString() Returns the String representation of this IlIntPolygon's values.
