Using a PanWindow

Take the following steps to start a project and to add some code that uses a PanWindow:

Start Visual Studio .NET.
Choose File->New->Project… from the menu.
In the New Project dialog box, choose either "Visual C# Projects" or "Visual Basic Projects" in the Projects Type List, and choose "Windows Application " in the Templates List.
Type the project name as "Using a PanWindow" 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 "\LEAD Technologies\LEADTOOLS 15\Bin\DotNet\Win32 " folder and select the following DLLs:
- Leadtools.dll
- Leadtools.Codecs.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 "C:\Program Files\LEAD Technologies\LEADTOOLS 15\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:
[Visual Basic]
```
 
Imports Leadtools
Imports Leadtools.Codecs
Imports Leadtools.WinForms            
```
[C#]
```
using Leadtools;
using Leadtools.Codecs;
using Leadtools.WinForms; 
```

Property	Value
Dock	Fill

Add an event handler to the Form1 Load event and add the following code:

[Visual Basic]


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   ' load an image into the viewer
   RasterCodecs.Startup()
   Dim codecs As New RasterCodecs()
   rasterImageViewer1.Image = codecs.Load("C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image2.cmp")
   RasterCodecs.Shutdown()
   
   ' Create an instance of Form2
   Dim form As New Form2
   Form.Show()
   
   ' Set the attribute of the pan viewer
   Form.PanViewer.BackColor = Color.Bisque
   form.PanViewer.Viewer = RasterImageViewer1
   Form.PanViewer.BorderStyle = BorderStyle.None
   Form.PanViewer.RectangleColor = Color.Blue
   Form.PanViewer.ImageColor = Color.FromArgb(128, 0, 0, 0)
   Form.PanViewer.Cursor = Cursors.Hand
End Sub

[C#]


private void Form1_Load(object sender, System.EventArgs e)
{
   // load an image into the viewer
   RasterCodecs.Startup();
   RasterCodecs codecs = new RasterCodecs();
   rasterImageViewer1.Image = codecs.Load(@"C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Image2.cmp");
   RasterCodecs.Shutdown();
   
   // Create an instance of Form2
   Form2 form = new Form2();
   form.Show();
   
   // Set the attribute of the pan viewer
   form.PanViewer.BackColor = Color.Bisque;
   form.PanViewer.Viewer = rasterImageViewer1;
   form.PanViewer.BorderStyle = BorderStyle.None;
   form.PanViewer.RectangleColor = Color.Blue;
   form.PanViewer.ImageColor = Color.FromArgb(128, 0, 0, 0);
   form.PanViewer.Cursor = Cursors.Hand;
}

Select Project->Add Windows Forms and add a new Form to the project. Switch to Form2 code view (Right click Form2 in the solution explorer then select View Code) and add the following lines at the beginning of the file:
[Visual Basic]
```
Imports Leadtools.WinForms
```
[C#]
```
using Leadtools.WinForms;
```

Add an event handler to the Form2 Load event and add the following code: [Visual Basic]


Private myPanViewer As RasterImagePanViewer

Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   myPanViewer = New RasterImagePanViewer
   myPanViewer.Dock = DockStyle.Fill
   Controls.Add(myPanViewer)
   myPanViewer.BringToFront()
End Sub

Public ReadOnly Property PanViewer() As RasterImagePanViewer
   Get
      Return myPanViewer
   End Get
End Property

[C#]


private RasterImagePanViewer panViewer;

private void Form2_Load(object sender, System.EventArgs e)
{
   panViewer = new RasterImagePanViewer();
   panViewer.Dock = DockStyle.Fill;
   Controls.Add(panViewer);
   panViewer.BringToFront();
}

public RasterImagePanViewer PanViewer
{
   get
   {
      return panViewer;
   }
}

Build, and Run the program to test it.
