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 click OK. If desired, type a new location for your project or select a directory using the Browse button, and then click 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 the "<LEADTOOLS_INSTALLDIR>\Bin\DotNet\Win32 " folder and select the following DLLs:
- Leadtools.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 the "\LEADTOOLS 18\Bin\DotNet\Win32" folder, 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;

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
                Dim codecs As New RasterCodecs()
                rasterImageViewer1.Image = codecs.Load("C:\Users\Public\Documents\LEADTOOLS Images\Image2.cmp")
                
                ' 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 codecs = new RasterCodecs();
                rasterImageViewer1.Image = codecs.Load(@"C:\Users\Public\Documents\LEADTOOLS Images\Image2.cmp");
                
                // 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 code it as follows: [Visual Basic]


             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

[C#]


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

Add the following code to class Form2: [Visual Basic]


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

[C#]


             private RasterImagePanViewer panViewer;
             public RasterImagePanViewer PanViewer
             {
                get
                {
                   return panViewer;
                }
             }

Build, and Run the program to test it.
