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.dll
Leadtools.Codecs.dll
Leadtools.Codecs.Cmp.dll
Leadtools.Codecs.Bmp.dll
Leadtools.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;

15: afterPic.HorizontalAlignMode = beforePic.HorizontalAlignMode;
16: afterPic.VerticalAlignMode = beforePic.VerticalAlignMode;
17: afterPic.AutoResetScaleFactor = beforePic.AutoResetScaleFactor;
18: panelAfter.Controls.Add(afterPic);
19: afterPic.BringToFront();
20:
