示例1: IsFit
public bool IsFit(Point[] points)
{
// Note: rigorously calculating distance(point,ellipse) is very hard...
// overlay the regions and compare the areas, for now.
using (GraphicsPath polygp = new GraphicsPath())
using (GraphicsPath elligp = new GraphicsPath())
using (Matrix m = new Matrix())
{
// Set up gp for stroke.
polygp.AddPolygon(points);
// Set up gp for ellipse.
elligp.AddEllipse((float)-mj,(float)-mn,(float)mj*2,(float)mn*2);
m.Translate((float)cx,(float)cy);
m.Rotate((float)th);
elligp.Transform(m);
// Prepare regions for area-calculation.
using (Region xor = new Region(elligp))
using (Region isc = new Region(elligp))
{
xor.Xor(polygp);
isc.Intersect(polygp);
float badarea = Geometry.CalculateArea(xor);
float iscarea = Geometry.CalculateArea(isc);
float ratio = iscarea/badarea;
//heuristic: 10.0 seems about right.
