Implementing Non Automated Annotation Program (Deprecated)

Summary

Take the following steps to create and run a program that implements non-automated annotations:

Start Visual Studio .NET.
Choose File->New->Project… from the menu.
In the New Project dialog box, choose either "Visual C# Projects" or "VB Projects" in the Projects Type List, and choose "Windows Application " in the Templates List.
Type the project name as "Implementing Non Automated Annotation" 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, and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and browse to Leadtools For .NET "<LEADTOOLS_INSTALLDIR>\Bin\DotNet\Win32 " folder and select the following DLLs:
- Leadtools.dll
- Leadtools.Annotations.dll
- Leadtools.Codecs.dll
- Leadtools.Codecs.Cmp.dll
- Leadtools.WinForms.dll
Click the Select button and then press the OK button to add the above DLLs to the application.
Make sure Form1 is in design view. Go to the toolbox (View->Toolbox) and Drag and drop an instance of RasterImageViewer to the form. If you do not have RasterImageViewer in your toolbox, select Tools->Add Remove Toolbox Items from the menu. Click Browse and then select Leadtools.WinForms.DLL from "<LEADTOOLS_INSTALLDIR>\Bin\DotNet\Win32" and then click Open and then click OK.
Change the following properties:

Property	Value
Dock	Fill

Switch to Form1 code view (right-click Form1 in the solution explorer then select View Code ) and add the following lines at the beginning of the file:

Imports Leadtools 
Imports Leadtools.Annotations 
Imports Leadtools.Codecs 
Imports Leadtools.WinForms

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms;

Declare the following private variable:

' Annotation container object 
Private annContainerObj As AnnContainer

// Annotation container object 
private AnnContainer annContainerObj;

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

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
   ' intitialize a new RasterCodecs object 
   Dim codecs As New RasterCodecs() 
   ' load the main image into our viewer 
   rasterImageViewer1.Image = codecs.Load("C:\Users\Public\Documents\LEADTOOLS Images\Sample1.cmp") 
   If (Not IsNothing(RasterImageViewer1.Image)) Then 
      ' initialize the AnnContainer object and associate it with rasterImageViewer1 image 
      annContainerObj = New AnnContainer 
      annContainerObj.Bounds = New AnnRectangle(0, 0, RasterImageViewer1.ImageSize.Width, RasterImageViewer1.ImageSize.Height, AnnUnit.Pixel) 
      annContainerObj.Name = "Container" 
      annContainerObj.Visible = True 
      annContainerObj.UnitConverter = New AnnUnitConverter(96, 96) 
      ' create Annotation Note Object and add it to the container 
      annContainerObj.Objects.Add(CreateAnnNoteObject(New AnnRectangle(annContainerObj.Bounds.Right / 2, annContainerObj.Bounds.Bottom / 2, (annContainerObj.Bounds.Right / 4) - 1, (annContainerObj.Bounds.Bottom / 4) - 1))) 
   End If 
End Sub

private void Form1_Load(object sender, System.EventArgs e) 
{ 
   // intitialize a new RasterCodecs object 
   RasterCodecs codecs = new RasterCodecs(); 
   // load the main image into our viewer 
   rasterImageViewer1.Image = codecs.Load(@"C:\Users\Public\Documents\LEADTOOLS Images\Sample1.cmp"); 
                    
   if(rasterImageViewer1.Image != null) 
   { 
      // initialize the AnnContainer object and associate it with rasterImageViewer1 image 
      annContainerObj = new AnnContainer(); 
      annContainerObj.Bounds = new AnnRectangle(0, 0, rasterImageViewer1.ImageSize.Width, rasterImageViewer1.ImageSize.Height, AnnUnit.Pixel); 
      annContainerObj.Name = "Container"; 
      annContainerObj.Visible = true; 
      annContainerObj.UnitConverter = new AnnUnitConverter(96, 96); 
      // create Annotation Note Object and add it to the container 
      annContainerObj.Objects.Add(CreateAnnNoteObject(new AnnRectangle(annContainerObj.Bounds.Right/2, annContainerObj.Bounds.Bottom/2, (annContainerObj.Bounds.Right/4) - 1, (annContainerObj.Bounds.Bottom/4) - 1))); 
   } 
}

Add an event handler to the rasterImageViewer1 TransformChanged event and code it as follows:

Private Sub RasterImageViewer1_TransformChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RasterImageViewer1.TransformChanged 
   If (Not IsNothing(annContainerObj)) Then 
      annContainerObj.Transform = RasterImageViewer1.Transform.Clone() 
   End If 
End Sub

private void rasterImageViewer1_TransformChanged(object sender, System.EventArgs e) 
{ 
   if(annContainerObj != null) 
      annContainerObj.Transform = rasterImageViewer1.Transform.Clone(); 
}

Add an event handler to the rasterImageViewer1 PostImagePaint event and code it as follows:

Private Sub RasterImageViewer1_PostImagePaint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles RasterImageViewer1.PostImagePaint 
   If (Not IsNothing(annContainerObj)) Then 
      annContainerObj.Draw(e.Graphics) 
   End If 
End Sub

private void rasterImageViewer1_PostImagePaint(object sender, System.Windows.Forms.PaintEventArgs e) 
{ 
   if(annContainerObj != null) 
      annContainerObj.Draw(e.Graphics); 
}

Add the CreateAnnNoteObject function code to class Form1:

Private Function CreateAnnNoteObject(ByVal boundingRect As AnnRectangle) As AnnObject 
   Dim annNoteObj As AnnNoteObject = New AnnNoteObject 
   annNoteObj.Text = "This is my Text" 
   annNoteObj.TextColor = Color.FromArgb(255, 0, 0) 
   annNoteObj.Pen = New AnnPen(Color.Red, New AnnLength(3)) 
   annNoteObj.Brush = New AnnSolidBrush(Color.Yellow) 
   annNoteObj.Font = New AnnFont(New FontFamily("Arial"), New AnnLength(14), FontStyle.Bold) 
   annNoteObj.Hyperlink = "Notepad.exe" 
   annNoteObj.Bounds = boundingRect 
   Return annNoteObj 
End Function

private AnnObject CreateAnnNoteObject( AnnRectangle boundingRect) 
{ 
   AnnNoteObject annNoteObj = new AnnNoteObject(); 
   annNoteObj.Text = "This is my Text"; 
   annNoteObj.TextColor = Color.FromArgb(255, 0, 0); 
   annNoteObj.Pen = new AnnPen(Color.Red , new AnnLength(3)); 
   annNoteObj.Brush = new AnnSolidBrush(Color.Yellow); 
   annNoteObj.Font = new AnnFont(new FontFamily("Arial"), new AnnLength(14), FontStyle.Bold); 
   annNoteObj.Hyperlink = "Notepad.exe"; 
   annNoteObj.Bounds = boundingRect; 
   return annNoteObj; 
}

Build, and Run the program to test it.
