LeadTools创建“将一图像添加至另一图像”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“AddImage”，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.Codecs.Bmp.dllLeadtools.ImageProcessing.Core.dll Leadtools.ImageProcessing.Effects.dll Leadtools.ImageProcessing.SpecialEffects.dll Leadtools.WinForms.dll

3、从工具箱（视图->工具箱），添加10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.WinForms; 3: using Leadtools.Codecs; 4: using Leadtools.Codecs.Cmp; 5: using Leadtools.Codecs.Bmp; 6: using Leadtools.ImageProcessing; 7: using Leadtools.ImageProcessing.Core; 8: using Leadtools.ImageProcessing.Effects; 9: using Leadtools.ImageProcessing.SpecialEffects;

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();20:21: codecs = new RasterCodecs();22: codecs.ThrowExceptionsOnInvalidImages = true;23: beforePic.Image = codecs.Load(Path.Combine(Application.StartupPath, @"..\..\Pic\cannon.jpg"));
