创建一个 Diagram
Aspose.Diagram for .NET 允许您从自己的应用程序中读取和创建 Microsoft Visio 图表,无需 Microsoft Office 自动化。创建新文档的第一步是创建一个 diagram。然后添加形状和连接器构建 diagram。使用默认构造函数Diagram类创建一个新的 diagram。

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET | |
// The path to the documents directory. | |
string dataDir = RunExamples.GetDataDir_Diagrams(); | |
// Create directory if it is not already present. | |
bool IsExists = System.IO.Directory.Exists(dataDir); | |
if (!IsExists) | |
System.IO.Directory.CreateDirectory(dataDir); | |
// Initialize a new Visio | |
Diagram diagram = new Diagram(); | |
dataDir = dataDir + "CreateDiagram_out.vsdx"; | |
// Save in the VSDX format | |
diagram.Save(dataDir, SaveFileFormat.VSDX); |
这个例子的工作原理如下:
- 创建 Diagram 类的对象。
- 获取特定页面
- 得到特定的形状
- 获取Shape文字并旋转文字
- 调用 Diagram 类对象的 Save 方法,并传递完整的文件路径和 DiagramSaveOptions 对象。
旋转文字编程范例
下面的示例代码显示了如何旋转 Visio diagram 中的文本。

// For complete examples and data files, please go to https://github.com/aspose-diagram/Aspose.Diagram-for-.NET | |
// The path to the documents directory. | |
string dataDir = RunExamples.GetDataDir_ShapeText(); | |
// Call the diagram constructor to load diagram from a VDX file | |
Diagram diagram = new Diagram(dataDir + "UpdateShapeText.vsd"); | |
// Get page by name | |
Page page = diagram.Pages.GetPage("Flow 1"); | |
// Find a particular shape and update its text | |
foreach (Aspose.Diagram.Shape shape in page.Shapes) | |
{ | |
if (shape.NameU.ToLower() == "process" && shape.ID == 1) | |
{ | |
shape.Text.Value.Clear(); | |
shape.Text.Value.Add(new Txt("New Text")); | |
// Set orientation angle | |
double angleDeg = 90; | |
double angleRad = (Math.PI / 180) * angleDeg; | |
shape.TextXForm.TxtAngle.Value = angleRad; | |
} | |
} | |
// Save diagram | |
diagram.Save(dataDir + "UpdateShapeText_out.vdx", SaveFileFormat.VDX); |
