WPF Graphics Rendering Services - Shape

Members of the System.Windows.Shapes namespace provide the most straightforward, most interactive, yet most memory-intensive way to render a two-dimensional image. This namespace (defined in the PresentationFramework.dll assembly) is quite small and consists of only six sealed classes that extend the abstract Shape base class:
  • Ellipse
  • Rectangle
  • Line
  • Polygon
  • Polyline
  • Path : provides the ability to define complex 2D graphical data represented as a collection of independent geometries.
    • LineGeometry 
    • RectangleGeometry 
    • EllipseGeometry 
    • GeometryGroup 
    • CombinedGeometry 
    • PathGeometry

Alternative to IValueConvert, QuickConverter

https://quickconverter.codeplex.com/ Quick Setup Steps Add the assembly reference to your project. This can also easily be done using  the NuGet package . Add the namespaces to Quick Converter that it will need to know about (before any xaml that uses it is loaded). e.g. In your WPF application's App.xaml.cs file: public   partial   class   App  :  Application { public  App() :  base () { // Setup Quick Converter. // Add the System namespace so we can use primitive types (i.e. int, etc.). QuickConverter. EquationTokenizer .AddNamespace( typeof ( object )); // Add the System.Windows namespace so we can use Visibility.Collapsed, etc. QuickConverter. EquationTokenizer .AddNamespace( typeof (System.Windows. Visibility )); } } Add the Quick Converter namespace to your xaml files so you can ref...
