Using WPF Non Automated Annotations in Run Mode
Take the following steps to create and run a program that implements non-automated annotations, This program will let you create a Note and a button annotations, set the user mode through a menu, and activate the annotations by left clicking on the annotation.
  1. Start Visual Studio .NET.
  2. Choose File->New->Project… from the menu.
  3. In the New Project dialog box, choose either "Visual C# Projects" - NET Framework 3.0 or "Visual Basic Projects" - NET Framework 3.0 in the Projects Type List, and choose "Windows Application (WPF) " in the Templates List.
  4. Type the project name as "Using Non Automated Annotations in Run Mode" in the Project Name field, and then choose OK. If desired, type a new location for your project or select a directory using the Browse button, and then choose OK .
  5. In the "Solution Explorer" window, right-click on the "References" folder (For a VB project, right-click on the project file in solution explorer), and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and browse to Leadtools For .NET "\LEAD Technologies\LEADTOOLS 16\Bin\DotNet\Win32 " folder and select the following DLLs:
    • Leadtools.Windows.Annotations.dll
    • Leadtools.Windows.Controls.dll
    • Leadtools.Windows.Media.Transitions.dll
    Click the Select button and then press the OK button to add the above DLLs to the application.
  6. Open Window1.xaml file and replace it by the following: [Visual Basic]
    				
    <Window x:Class="Window1"
               xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
               xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
               Title="Using_Non_Automated_Annotations_in_Run_Mode" Height="300" Width="300"
               Loaded="WindowLoaded"
               xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls"
        >
        <StackPanel>
           <RadioButton Name="rbDesignMode" GroupName="UserMode" Content="Design Mode" IsChecked="True" Checked="CheckedChanged"/>
           <RadioButton Name="rbRunMode" GroupName="UserMode" Content="Run Mode" Checked="CheckedChanged"/>
           <Separator/>
           <Leadtools_Windows_Controls:BitmapSourceViewer x:Name="imageViewer1" Width="NaN" Height="NaN"/>
        </StackPanel>
    </Window>
    
    [C#]
    				
    <Window x:Class="Using_Non_Automated_Annotations_in_Run_Mode.Window1"
               xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
               xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
               Title="Using_Non_Automated_Annotations_in_Run_Mode" Height="300" Width="300"
               Loaded="WindowLoaded"
               xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls"
        >
        <StackPanel>
           <RadioButton Name="rbDesignMode" GroupName="UserMode" Content="Design Mode" IsChecked="True" Checked="CheckedChanged"/>
           <RadioButton Name="rbRunMode" GroupName="UserMode" Content="Run Mode" Checked="CheckedChanged"/>
           <Separator/>
           <Leadtools_Windows_Controls:BitmapSourceViewer x:Name="imageViewer1" Width="NaN" Height="NaN"/>
        </StackPanel>
    </Window>
    
  7. Switch to Window1 code view (for VB project right-click Window1 in the solution explorer then select View Code and for C# project open Window1.xaml.cs file) and add the following lines at the beginning of the file: [Visual Basic]
    				
    Imports Leadtools.Windows.Annotations
    
    [C#]
    				
    using Leadtools.Windows.Annotations;
    
  8. Declare the following private enumeration: [Visual Basic]
    				
    ' user mode
    Private Enum UserModeEnum
       RunMode
       DesignMode
    End Enum
    
    [C#]
    				
    // user mode
    private enum UserModeEnum
    {
       RunMode,
       DesignMode
    }
    
  9. Declare the following private variables: [Visual Basic]
    				
    ' Annotation container object
    Private annContainerObj As AnnContainer
    ' Current user mode
    Private currentUserMode As UserModeEnum
    
    [C#]
    				
    // Annotation container object
    private AnnContainer annContainerObj;
    // Current user mode
    private UserModeEnum currentUserMode;
    
  10. Add the following functions code to class Window1: [Visual Basic]
    				
    Private Sub WindowLoaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
       ' load the main image into our viewer 
       imageViewer1.Source = New BitmapImage(New Uri("C:\Users\Public\Documents\LEADTOOLS Images\eye.gif"))
       ' we are in design mode now
       currentUserMode = UserModeEnum.DesignMode
       If (Not imageViewer1.Source Is Nothing) Then
          ' initialize the AnnContainer object and associate it with rasterImageViewer1 image
          annContainerObj = New AnnContainer()
          annContainerObj.Width = imageViewer1.Source.Width
          annContainerObj.Height = imageViewer1.Source.Height
          ' set the annContainerObj as a content of BitmapSourceViewer.
          imageViewer1.Content = annContainerObj
          ' create Annotation Button Object and add it to the container
          annContainerObj.Children.Add(CreateAnnButtonObject(New Rect(1, 1, annContainerObj.Width / 4, annContainerObj.Height / 4)))
          ' create Annotation Note Object and add it to the container
          annContainerObj.Children.Add(CreateAnnNoteObject(New Rect(annContainerObj.Width / 2, annContainerObj.Height / 2, (annContainerObj.Width / 4) - 1, (annContainerObj.Height / 4) - 1)))
          'handle the container MouseLeftButtonDown event
          AddHandler annContainerObj.MouseLeftButtonDown, New MouseButtonEventHandler(AddressOf annContainerObj_MouseLeftButtonDown)
       End If
    End Sub
    Sub annContainerObj_MouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
       If (imageViewer1.Source Is Nothing) Then
          Return
       End If
       If (currentUserMode = UserModeEnum.RunMode) Then
          Dim obj As AnnObjectBase = annContainerObj.HitTest(e.GetPosition(annContainerObj))
          If ((Not obj Is Nothing) AndAlso ((TypeOf obj Is AnnButtonObject) Or (TypeOf obj Is AnnNoteObject))) Then
             If (TypeOf obj Is AnnButtonObject) Then

             End If
          End If
       End If
    End Sub
    Private Sub CheckedChanged(ByVal sender As Object, ByVal e As RoutedEventArgs)
       UserModeChanged(sender)
    End Sub
    Private Sub UserModeChanged(ByVal sender As Object)
       currentUserMode = IIf(sender Is rbDesignMode, UserModeEnum.DesignMode, UserModeEnum.RunMode)
    End Sub
    Private Function CreateAnnButtonObject(ByVal boundingRect As Rect) As AnnObjectBase

  11. Build, and Run the program to test it. Click on the Note and Button annotations. Since the User Mode is Design Mode, nothing happens. Select Run Mode Radio button then click on each annotation.
