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.dllLeadtools.Codecs.dllLeadtools.Codecs.Cmp.dllLeadtools.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;
