LeadTools创建“艺术效果”应用程序的具体步骤

操作方法

• 01

  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“ApplyArtisticEffects”，并使用“浏览”按钮选择您工程的存储路径，点击“确定”。

• 02

  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.Effects.dll Leadtools.ImageProcessing.SpecialEffects.dll Leadtools.WinForms.dll

• 03

  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：

  

• 04

  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; 5: using Leadtools.ImageProcessing.Effects; 6: using Leadtools.ImageProcessing.SpecialEffects;

• 05

  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;

• 06

  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\Image.jpg"));
