LeadTools创建“检测边缘”应用程序的具体步骤
1、打开Visual Studio .NET。点击 文件->新建->项目…。打开新建项目对话框后，在模板中选择“Visual C#”或“Visual Basic”，随后选择“Windows窗体应用程序”。在名称栏中输入项目名称“DetectEdgesAndLines”，并使用“浏览”按钮选择您工程的存储路径，点击“确定”。
2、在“解决方案资源管理器”中，右击“引用”，选择“添加引用”。根据当前工程的 Framework 版本和生成目标平台，选择添加相应的LeadTools控件，例如工程中的版本为 Framework 4.0、生成目标平台是 x86，则浏览选择Leadtools For .NET文件夹” <LEADTOOLS_INSTALLDIR>\Bin\DotNet4\Win32”,选择以下的DLL“：
Leadtools.dll
Leadtools.Codecs.dll
Leadtools.Codecs.Cmp.dll
Leadtools.ImageProcessing.Color.dll
Leadtools.ImageProcessing.Effects.dll
Leadtools.ImageProcessing.SpecialEffects.dll
Leadtools.WinForms.dll
3、从工具箱（视图->工具箱），添加12个RadioButton控件（将RadioButton的Text属性依照下表修改），两个Panel控件（Name分别修改为panelBefore和panelAfter）。如下图：
4、切换至Form1的代码视图（右击Form1，选择查看代码），将下面几行代码添加到文件开始处：
1: using Leadtools;
2: using Leadtools.Codecs;
3: using Leadtools.WinForms;
4: using Leadtools.ImageProcessing.Effects;
5: using Leadtools.ImageProcessing.SpecialEffects;
6: using Leadtools.ImageProcessing.Color;
5、将以下变量添加至Form1类：
1: private RasterImageViewer beforePic;
2: private RasterImageViewer afterPic;
3: private RasterCodecs codecs;
4: private RasterImage temp;
6、添加Form1 Load事件句柄，在其中添加以下代码：
1: beforePic = new RasterImageViewer();
2: beforePic.BackColor = Color.DarkCyan;
3: beforePic.Dock = DockStyle.Fill;
4: beforePic.InteractiveMode = RasterViewerInteractiveMode.Pan;
5: beforePic.HorizontalAlignMode = RasterPaintAlignMode.Center;
6: beforePic.VerticalAlignMode = RasterPaintAlignMode.Center;
7: beforePic.AutoResetScaleFactor = false;
8: panelBefore.Controls.Add(beforePic);
9: beforePic.BringToFront();
10:
11: afterPic = new RasterImageViewer();
12: afterPic.BackColor = beforePic.BackColor;
13: afterPic.Dock = beforePic.Dock;
14: afterPic.InteractiveMode = beforePic.InteractiveMode;
15: afterPic.HorizontalAlignMode = beforePic.HorizontalAlignMode;
16: afterPic.VerticalAlignMode = beforePic.VerticalAlignMode;
17: afterPic.AutoResetScaleFactor = beforePic.AutoResetScaleFactor;
18: panelAfter.Controls.Add(afterPic);
19: afterPic.BringToFront();
