Working with Automated Annotations

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

1. Start Visual Studio .NET.
2. Choose File->New->Project… from the main menu.
3. In the New Project dialog box, select either "Visual C# " or "VB " in the Installed Templates List, and choose "Windows Forms Application " in the Templates List.
4. Type the project name as "Working With Automated Annotations" in the Name field, and then click OK. If desired, type a new location for your project or select a directory using the Browse button, and then click OK.

5. In the "Solution Explorer" window, right-click the "References" folder, and choose "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and browse to the "<LEADTOOLS_INSTALLDIR>\Bin\DotNet4\Win32 " folder and select the following DLLs:

   • Leadtools.dll
   • Leadtools.Annotations.Core.dll
   • Leadtools.Annotations.Rendering.WinForms.dll
   • Leadtools.Annotations.Designers.dll
   • Leadtools.Annotations.Automation.dll
   • Leadtools.Annotations.WinForms.dll
   • Leadtools.Codecs.dll
   • Leadtools.Codecs.Cmp.dll
   • Leadtools.Controls.WinForms.dll

6. Click Add and then click OK to add the above DLLs to the application.

7. Switch to Form1 code view (right-click Form1 in the Solution Explorer and then choose View Code) and add the following lines at the beginning of the file:

   C#

   VB
                      
   Imports Leadtools 
   Imports Leadtools.Annotations.Core 
   Imports Leadtools.Annotations.Designers 
   Imports Leadtools.Annotations.Automation 
   Imports Leadtools.Codecs 
   Imports Leadtools.Controls 
   Imports Leadtools.Annotations.WinForms 
                     
        

                      
   using Leadtools; 
   using Leadtools.Annotations.Core; 
   using Leadtools.Annotations.Designers; 
   using Leadtools.Annotations.Automation; 
   using Leadtools.Codecs; 
   using Leadtools.Controls; 
   using Leadtools.Annotations.WinForms; 
                     
        

8. Declare the following private variables:

   C#

   VB
   Private automationControl As ImageViewerAutomationControl 
   Private viewer As ImageViewer 
   ' The Automation Manager is used to manage the automation mode. 
   Private annAutomationManager As AnnAutomationManager 
   Private WithEvents automation As AnnAutomation 
                     
        

   private ImageViewer viewer; 
   private ImageViewerAutomationControl automationControl; 
   // The Automation Manager is used to manage the automation mode. 
   private AnnAutomationManager annAutomationManager; 
   private AnnAutomation automation; 
                     
        

9. Add an event handler to the Form1 Load event and code it as follows:

   C#

   VB
                      
   Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load 
        viewer = New ImageViewer() 
        viewer.Dock = DockStyle.Fill 
                    
        automationControl = New ImageViewerAutomationControl() 
        automationControl.ImageViewer = viewer 
                    
        ' initialize a new RasterCodecs object 
        Dim codecs As New RasterCodecs() 
        ' load the main image into the viewer 
        viewer.Image = codecs.Load("C:\Users\Public\Documents\LEADTOOLS Images\Sample1.cmp") 
                    
        'initialize the interactive mode for the viewer 
        Dim automationInteractiveMode As AutomationInteractiveMode = New AutomationInteractiveMode() 
        automationInteractiveMode.AutomationControl = automationControl 
                    
        'add the interactive mode to the viewer 
        viewer.InteractiveModes.BeginUpdate() 
        viewer.InteractiveModes.Add(automationInteractiveMode) 
        viewer.InteractiveModes.EndUpdate() 
                    
        If(Not IsNothing(viewer.Image)) Then 
           ' create and set up the automation manager 
           annAutomationManager = New AnnAutomationManager 
           annAutomationManager.RestrictDesigners = True 
                    
           ' Instruct the manager to create all of the default automation objects. 
           annAutomationManager.CreateDefaultObjects() 
           Dim managerHelper As AutomationManagerHelper = New AutomationManagerHelper(annAutomationManager) 
           managerHelper.CreateToolBar() 
           Controls.Add(managerHelper.ToolBar) 
           Controls.Add(viewer) 
                    
           ' set up the automation (it will create the container as well) 
           automation = New AnnAutomation(annAutomationManager, automationControl) 
           ' set this automation as the active one 
           automation.Active = True 
                    
           automation.Container.Size = automation.Container.Mapper.SizeToContainerCoordinates(LeadSizeD.Create(viewer.Image.ImageWidth, viewer.Image.ImageHeight)) 
        End If 
   End Sub 
                     
        

                      
   private void Form1_Load(object sender, System.EventArgs e) 
   { 
     viewer = new ImageViewer(); 
     viewer.Dock = DockStyle.Fill; 
                    
     automationControl = new ImageViewerAutomationControl(); 
     automationControl.ImageViewer = viewer; 
                     
     // initialize a new RasterCodecs object 
     RasterCodecs codecs = new RasterCodecs(); 
     // load the main image into the viewer 
     viewer.Image = codecs.Load(@"C:\Users\Public\Documents\LEADTOOLS Images\Sample1.cmp"); 
                     
     // initialize the interactive mode for the viewer 
     AutomationInteractiveMode automationInteractiveMode = new AutomationInteractiveMode(); 
     automationInteractiveMode.AutomationControl = automationControl; 
                     
     // add the interactive mode to the viewer 
     viewer.InteractiveModes.BeginUpdate(); 
     viewer.InteractiveModes.Add(automationInteractiveMode); 
     viewer.InteractiveModes.EndUpdate(); 
                     
     if (viewer.Image != null) 
     { 
     // create and set up the automation manager 
     annAutomationManager = new AnnAutomationManager(); 
     annAutomationManager.RestrictDesigners = true; 
                     
     // Instruct the manager to create all of the default automation objects. 
     annAutomationManager.CreateDefaultObjects(); 
                     
     // initialize the manager helper and create the toolbar and add it then the viewer to the controls 
     AutomationManagerHelper managerHelper = new AutomationManagerHelper(annAutomationManager); 
     managerHelper.CreateToolBar(); 
     Controls.Add(managerHelper.ToolBar); 
     Controls.Add(viewer); 
                     
     // set up the automation (it will create the container as well) 
     automation = new AnnAutomation(annAutomationManager, automationControl); 
     // set this automation as the active one 
     automation.Active = true; 
                     
     //set the size of the container to the size of the viewer 
     automation.Container.Size = automation.Container.Mapper.SizeToContainerCoordinates(LeadSizeD.Create(viewer.Image.ImageWidth, viewer.Image.ImageHeight)); 
      } 
   }
