20 class Rectangle : IDrawable
21 {
22     public

24         uint width, height;
25         Color!ubyte color;
26     }
27 
28     this(uint width,uint height,Color!ubyte color);
29 
30     override void draw(IRenderer renderer,Vecf position) @safe
31     {
32         renderer.rectangle(position,width,height,color,true);
33     }
