Working with WPF Automated Annotation

Take the following steps to create and run a program that implements Automated Annotations:

Start Visual Studio .NET.
Choose File->New->Project… from the menu.
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.
Type the project name as "Working With Automated Annotations" 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 .
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 17\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.

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="Working_With_Automated_Annotations" Height="300" Width="300"
                            Loaded="WindowLoaded"
                            xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls"
                     >
                <DockPanel>
                   <StackPanel DockPanel.Dock="Top">
                      <RadioButton Name="rbDesignMode" GroupName="UserMode" Content="Design Mode" IsChecked="True" Checked="CheckedChanged"/>
                      <RadioButton Name="rbRunMode" GroupName="UserMode" Content="Run Mode" Checked="CheckedChanged"/>
                   </StackPanel>
                   <ToolBarTray Name="toolbarTray" DockPanel.Dock="Right" Orientation="Vertical"/>
                   <Leadtools_Windows_Controls:BitmapSourceViewer x:Name="imageViewer1" Width="NaN" Height="NaN"/>
                </DockPanel>
             </Window>

[C#]

             <Window x:Class="Working_With_Automated_Annotations.Window1"
                            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                            Title="Working_With_Automated_Annotations" Height="300" Width="300"
                            Loaded="WindowLoaded"
                            xmlns:Leadtools_Windows_Controls="clr-namespace:Leadtools.Windows.Controls;assembly=Leadtools.Windows.Controls"
                     >
                <DockPanel>
                   <StackPanel DockPanel.Dock="Top">
                      <RadioButton Name="rbDesignMode" GroupName="UserMode" Content="Design Mode" IsChecked="True" Checked="CheckedChanged"/>
                      <RadioButton Name="rbRunMode" GroupName="UserMode" Content="Run Mode" Checked="CheckedChanged"/>
                   </StackPanel>
                   <ToolBarTray Name="toolbarTray" DockPanel.Dock="Right" Orientation="Vertical"/>
                   <Leadtools_Windows_Controls:BitmapSourceViewer x:Name="imageViewer1" Width="NaN" Height="NaN"/>
                </DockPanel>
             </Window>

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;
             
```

Declare the following private variable:

[Visual Basic]

 
             ' Automation Manager used in managing the automation mode.
             Private annAutomationManager As AnnAutomationManager

[C#]

 
             // Automation Manager used in managing the automation mode.
             private AnnAutomationManager annAutomationManager;

Add the following function code to class Form1:

[Visual Basic]

 
             Private Sub WindowLoaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
                imageViewer1.Source = New BitmapImage(New Uri("C:\Users\Public\Documents\LEADTOOLS Images\eye.gif"))
             
                If (Not imageViewer1.Source Is Nothing) Then
             
                   ' create and setup the automation manager
                   annAutomationManager = New AnnAutomationManager()
             
                   ' Instruct the manager to create the default (all) automation objects.
                   annAutomationManager.CreateDefaultObjects()
             
                   ' create the toolbar and add it to the form
                   annAutomationManager.CreateToolBar()
                   toolbarTray.ToolBars.Add(annAutomationManager.ToolBar)
             
                   ' setup the automation (will create the container as well)
                   Dim automation As AnnAutomation = New AnnAutomation(annAutomationManager, imageViewer1)

                   automation.Active = True
                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)
                If (Not annAutomationManager Is Nothing) Then

                End If
             End Sub
             
             ' if the current designer is a button run designer, add a handler for Run
             Private Sub automation_CurrentDesignerChanged(ByVal sender As Object, ByVal e As EventArgs)
                Dim automation As AnnAutomation = DirectCast(sender, AnnAutomation)
                If (TypeOf (automation.CurrentDesigner) Is AnnButtonRunDesigner) Then
                   Dim buttonRunDesigner As AnnButtonRunDesigner = DirectCast(automation.CurrentDesigner, AnnButtonRunDesigner)
                   AddHandler buttonRunDesigner.Run, AddressOf buttonRunDesigner_Run
                End If
             End Sub
             
             Private Sub buttonRunDesigner_Run(ByVal sender As Object, ByVal e As AnnRunDesignerEventArgs)
                If (e.OperationStatus = AnnDesignerOperationStatus.End) Then
                   Dim btn As AnnButtonObject = e.Object
                   MessageBox.Show(String.Format("Button with text = {0} was clicked!", btn.Text))
                End If
             End Sub

Build, and Run the program to test it. You can now select objects from the toolbar, draw objects on top of the image, select the objects and move/change them. Right-click on any object to show its properties, etc.
Create a button annotation. Right-click on the annotation and change any of the button properties you wish. Select Run Mode Radio button, As you move the cursor over the audio annotation and the button annotation, the cursor changes to a hand. Click on the button annotation to call the program listed in the Hyperlink field.
