Click the points, I want to make from the polygon area on image.
myPolygon = new Polygon();
myPolygon.Stroke = Brushes.Black;
myPolygon.Fill = Brushes.LightYellow;
myPolygon.StrokeThickness = 2;
myPolygon.HorizontalAlignment = HorizontalAlignment.Left;
myPolygon.VerticalAlignment = VerticalAlignment.Center;
myPolygon.PreviewMouseLeftButtonDown += new MouseButtonEventHandler(Polygon_MouseDown);
myPolygon.PreviewMouseLeftButtonUp += new MouseButtonEventHandler(Polygon_MouseUp);
private void Polygon_MouseDown(object sender, MouseButtonEventArgs e)
{
Point p = e.GetPosition(image);
myPolygon.Points = new PointCollection() { new Point(p.X,p.Y) };
RootCanvas.Children.Add(myPolygon);
} //MouseClick Event BUT, did not click behavior.. I want draw a line along the points.
How can I do...?
We can draw Polygon using WPF canvas which is a collection of children objects.
Polygon p = new Polygon();
p.Stroke = Brushes.Black;
p.Fill = Brushes.LightBlue;
p.StrokeThickness = 1;
p.HorizontalAlignment = HorizontalAlignment.Left;
p.VerticalAlignment = VerticalAlignment.Center;
p.Points = new PointCollection() { new Point(10, 10), new Point(100, 100), new Point(200, 200) };
freeCanvas.Children.Add(p);
