Vector Graphics : Grouping Geometries

3/26/2011 2:55:19 PM

One of the descendent classes of Geometry is GeometryGroup. This allows you to combine one or more Geometry objects in a composite.

<Grid Background="LightCyan">
  <Path Stroke="Maroon"
        StrokeThickness="4"
        Fill="Green">
    <Path.Data>
      <GeometryGroup>
        <EllipseGeometry Center="200 150"
                         RadiusX="100"
                         RadiusY="50" />
        <RectangleGeometry
            Rect="200 150 100 100" />
      </GeometryGroup>
    </Path.Data>
  </Path>
</Grid>

Notice how the FillRule applies to this combination. Here’s another:

<Grid Background="LightCyan">
  <Path Stroke="Maroon"
        StrokeThickness="4"
        Fill="Green">
    <Path.Data>
      <GeometryGroup>
        <RectangleGeometry
            Rect=" 40  40 200 200" />
        <RectangleGeometry
            Rect=" 90  90 200 200" />
        <RectangleGeometry
            Rect="140 140 200 200" />
        <RectangleGeometry
            Rect="190 190 200 200" />
        <RectangleGeometry
            Rect="240 240 200 200" />
      </GeometryGroup>
    </Path.Data>
  </Path>
</Grid>
