- 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
- 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 17\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.
