Example: Closed path

public static int main (string[] args) {
// Create a context:
Cairo.ImageSurface surface = new Cairo.ImageSurface (Cairo.Format.ARGB32, 200, 200);
Cairo.Context context = new Cairo.Context (surface);

context.set_source_rgba (0, 0, 0, 1);
context.set_line_width (1);

// The rectangle:
context.move_to (10, 10);
context.rel_line_to (180, 0);
context.rel_line_to (0, 180);
context.rel_line_to (-180, 0);
context.close_path ();
context.stroke ();

// Save the image:
surface.write_to_png ("img.png");

return 0;
