I'm having trouble to find the best way to draw the below shape. I'm using the below code to draw an Ellipse
on visual layer.
But how can I only brush the quarters? I think it can be done using LinearGradientBrush
or RadialGradientBrush
but I don't know how use it.
var cntrpoint = space.FlipYAxis(x2, y2);
dc.DrawEllipse(Brushes.Transparent, pen, cntrpoint, 30, 30);
Like this:
var geometry = new GeometryGroup();
geometry.Children.Add(new RectangleGeometry(new Rect(1, 0, 1, 1)));
geometry.Children.Add(new RectangleGeometry(new Rect(0, 1, 1, 1)));
var drawing = new GeometryDrawing(Brushes.Black, null, geometry);
var brush = new DrawingBrush(drawing);
dc.DrawEllipse(brush, pen, cntrpoint, 30, 30);
