Take the following steps to start a project and to add some code that will demonstrate the automated annotation features of the LEADTOOLS Silverlight Control.

1. Start Visual Studio .NET 2008.
2. Start with the project that you created in Loading and displaying an image in Silverlight.
3. In the "Solution Explorer" window, right-click on the "References" folder for the Silverlight project and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, browse to the "<LEADTOOLS_INSTALLDIR>\Bin\Silverlight" or "<LEADTOOLS_INSTALLDIR>\Bin\Silverlight4" folder (depending on your target Silverlight version), and select Leadtools.Windows.Annotations.dll.
4. Open the Page.xaml file and copy the below XAML code into the editor:

   [XAML]

               <UserControl x:Class="Load_And_Display.MainPage"
                  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
                  xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls"
                  Width="800" Height="800">
                  <Grid x:Name="LayoutRoot" Background="White">
                     <StackPanel Orientation="Vertical" x:Name="stackPanel" >
                        <Leadtools_Windows_Controls:RasterImageViewer x:Name="viewerControl" SizeMode="Normal"  Width="500" Height="500"></Leadtools_Windows_Controls:RasterImageViewer>
                        <Button Name="myButton" Content="Load" FontSize="30" Click="Button_Click"></Button>
                        <RadioButton x:Name="_rbRunMode" Content="Run Mode" Checked="AnnotationMode_Changed" HorizontalAlignment="Center" FontSize="20"></RadioButton>
                        <RadioButton x:Name="_rbDesignMode" Content="Design Mode" Checked="AnnotationMode_Changed" HorizontalAlignment="Center" FontSize="20"></RadioButton>
                     </StackPanel>
                  </Grid>
               </UserControl>
                
               
   

5. Switch to Page.xaml code view (right-click Page.xaml in the solution explorer then select View Code) and add the following lines at the beginning of the file:

   [Visual Basic]

               Imports Leadtools.Windows.Annotations
                                                   
   

   [C#]

               using Leadtools.Windows.Annotations;
                                                           
   

6. Switch to Page.xaml code view (right-click Page.xaml in the solution explorer then select View Code) and add the following class level variable:

   [Visual Basic]

               Dim _automation As AnnAutomation
                                                   
   

   [C#]

               AnnAutomation _automation;
                                                           
   

7. Update the MainPage() function as shown below:

   [Visual Basic]

               Public Sub New()
                 InitializeComponent()
                 Dim MY_LICENSE_FILE As String = "d:\temp\TestLic.lic"
                 Dim MY_DEVELOPER_KEY As String = "xyz123abc"
                 RasterSupport.SetLicense(MY_LICENSE_FILE, MY_DEVELOPER_KEY)
                 Dim manager As AnnAutomationManager = New AnnAutomationManager()
                 manager.CreateDefaultObjects()
                 manager.CreateToolBar()
                 stackPanel.Children.Insert(0, manager.ToolBar)
                 manager.ToolBar.Orientation = Orientation.Horizontal
                 manager.ToolBar.HorizontalAlignment = HorizontalAlignment.Center
                 _automation = New AnnAutomation(manager, viewerControl)
                 _rbDesignMode.IsChecked = True
               End Sub
               
   

   [C#]

               public MainPage()
               {
                 InitializeComponent();
                 string MY_LICENSE_FILE = "d:\\temp\\TestLic.lic";
                 string MY_DEVELOPER_KEY = "xyz123abc";
                 RasterSupport.SetLicense(MY_LICENSE_FILE, MY_DEVELOPER_KEY);
                 AnnAutomationManager manager = new AnnAutomationManager();
                 manager.CreateDefaultObjects();
                 manager.CreateToolBar();
                 stackPanel.Children.Insert(0, manager.ToolBar);
                 manager.ToolBar.Orientation = Orientation.Horizontal;
                 manager.ToolBar.HorizontalAlignment = HorizontalAlignment.Center;
                 _automation = new AnnAutomation(manager, viewerControl);
                 _rbDesignMode.IsChecked = true;
               }
               
   

8. Add the following class function:

   [Visual Basic]

               Private Sub AnnotationMode_Changed(ByVal sender As Object, ByVal e As RoutedEventArgs)
                 If CBool(_rbDesignMode.IsChecked) Then
                    _automation.Manager.UserMode = AnnUserMode.Design
                 Else
                    _automation.Manager.UserMode = AnnUserMode.Run
                 End If
               End Sub
               
   

   [C#]

               private void AnnotationMode_Changed(object sender, RoutedEventArgs e)
               {
                 _automation.Manager.UserMode = (bool)_rbDesignMode.IsChecked ? AnnUserMode.Design : AnnUserMode.Run;
               }
               
   

9. Build, and Run the program to test it.

   Click the "Load" button and select a valid image.

   NOTE: if you encounter and "Invalid File Format" or "Feature Not Supported" exception, please refer to the topic Invalid File Format/Feature Not Supported.

   Use the toolbar above the viewer to select annotations. The radio buttons will allow you to switch between design and run mode.
