Drawing Brush is a new addition to the brush types since GDI+. A Drawing Brush can be used to paint an area with shapes, text, images, and even video. The <DrawingBrush/> represents the drawing brush in XAML. A Drawing Brush uses drawing objects GeomertyDrawing, ImageDrawing, VideoDrawing, and GylphRunDrawing to draw shapes, images, video, and text respectively.

The following code uses a DrawingBrush to fill two ellipses. I will cover DrawingBrush objects, its methods and properties in more details in my seperate article.

<Rectangle Width="300" Height="300" Stroke="Black" StrokeThickness="2">

    <Rectangle.Fill>          

        <DrawingBrush>              

            <DrawingBrush.Drawing>               

                <GeometryDrawing Brush="Green">                          

                    <GeometryDrawing.Geometry>                                   

                       <GeometryGroup>                                        

                            <EllipseGeometry RadiusX="0.1" RadiusY="0.5" Center="0.5,0.5" />                                         

                            <EllipseGeometry RadiusX="0.5" RadiusY="0.1" Center="0.5,0.5" />                                       

                        </GeometryGroup>

                    </GeometryDrawing.Geometry>                       

                </GeometryDrawing>                   

            </DrawingBrush.Drawing>    

        </DrawingBrush>      

    </Rectangle.Fill>    

</Rectangle>

 

The output looks like Figure 1.
