using System.Windows.Forms;
using Leadtools;
using Leadtools.Codecs;
using Leadtools.WinForms;
using Leadtools.Annotations;

3.主界面添加相关控件

 
4.后台代码编写

        RasterImageViewer viewer = new RasterImageViewer();
        RasterImage img;
        AnnAutomationManager annger;
        AnnAutomation automation;

private void initControl() {
            Support.SetLicense();
            viewer.Dock = DockStyle.Fill;
            panel1.Controls.Add(viewer);
            viewer.HorizontalAlignMode = RasterPaintAlignMode.Center;
            viewer.VerticalAlignMode = RasterPaintAlignMode.Center;
            loadImage("qwe.jpg");
            if (viewer.Image != null)
            {
                // create and setup the automation manager 
                annger = new AnnAutomationManager();

                // Instruct the manager to create the default (all) automation objects. 
                annger.CreateDefaultObjects();

                // create the toolbar and add it to the form 
                annger.CreateToolBar();
                Controls.Add(annger.ToolBar);

                // setup the automation (will create the container as well) 
                automation = new AnnAutomation(annger, viewer);

                // add an event handler for changes to the current designer 
                automation.CurrentDesignerChanged += new EventHandler(automation_CurrentDesignerChanged);

                // setup this automation as the active one 
                automation.Active = true;
            }
            toolStripComboBox1.SelectedIndex = 0;
        }

private void loadImage(string filename)
        {
            img = new RasterCodecs().Load(filename);
            viewer.Image = img;
        }

private void automation_CurrentDesignerChanged(object sender, EventArgs e)
        {
            AnnAutomation automation = sender as AnnAutomation;
            AnnButtonRunDesigner buttonRunDesigner = automation.CurrentDesigner as AnnButtonRunDesigner;
            if (buttonRunDesigner != null)
                buttonRunDesigner.Run += new EventHandler(buttonRunDesigner_Run);
        }

private void buttonRunDesigner_Run(object sender, AnnRunDesignerEventArgs e)
        {
            if (e.OperationStatus == AnnDesignerOperationStatus.End)
            {
                AnnButtonObject btn = e.Object as AnnButtonObject;
                MessageBox.Show(string.Format("Button with text = {0} was clicked!", btn.Text));
            }
        }

private void loadImage(string filename)
        {
            img = new RasterCodecs().Load(filename);
            viewer.Image = img;
        }

private void toolStripComboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            annger.UserMode = (toolStripComboBox1.SelectedIndex == 0) ? AnnUserMode.Design : AnnUserMode.Run;
        }

5.编译运行
