使用连接索引连接形状

在形状上添加新的连接并使用连接索引连接形状

Aspose.Diagram for .NET API 已经允许开发人员在形状上添加新的连接点，开发人员现在可以使用连接索引连接形状。

使用连接索引连接形状

由公开的 ConnectShapesViaConnectorIndex 成员页类可用于使用连接索引连接形状。以下代码显示了如何连接形状：

  1. 初始化一个新绘图。
  2. 放置四个矩形
  3. 添加两个额外的连接点，以便在底部边框线上有三个连接点
  4. 使用动态连接器将每个底部连接的第一个形状连接到顶部的其他三个矩形形状
  5. 保存图纸

使用连接索引连接形状编程示例

在您的 .NET 应用程序中使用以下代码，使用连接索引与 Aspose.Diagram for .NET API 连接形状。

C#

 // initialize a new drawing

Diagram diagram = new Diagram();

// get page by index

Aspose.Diagram.Page page = diagram.Pages[0];

// add masters

string connectorMaster = "Dynamic connector", rectangle = "Rectangle";

int pageNumber = 0;

double width = 2, height = 2, pinX = 4.25, pinY = 9.5;

diagram.AddMaster(@"C:\temp\Basic Shapes.vss", rectangle);

diagram.AddMaster(@"C:\temp\Basic Shapes.vss", connectorMaster);

// add shapes

long shape1_ID = diagram.AddShape(4.5, 7, rectangle, pageNumber);

long shape2_ID = diagram.AddShape(2.25, 4.5, rectangle, pageNumber);

long shape3_ID = diagram.AddShape(4.5, 4.5, rectangle, pageNumber);

long shape4_ID = diagram.AddShape(6.75, 4.5, rectangle, pageNumber);

// get shapes by ID

Aspose.Diagram.Shape shape1 = page.Shapes.GetShape(shape1_ID);

Aspose.Diagram.Shape shape2 = page.Shapes.GetShape(shape2_ID);

Aspose.Diagram.Shape shape3 = page.Shapes.GetShape(shape3_ID);

Aspose.Diagram.Shape shape4 = page.Shapes.GetShape(shape4_ID);

// add two more connection points

Connection connection1 = new Connection();

connection1.X.Ufe.F = "Width*0.33";

connection1.Y.Ufe.F = "Height*0";

Connection connection3 = new Connection();

connection3.X.Ufe.F = "Width*0.66";

connection3.Y.Ufe.F = "Height*0";

shape1.Connections.Add(connection1);

shape1.Connections.Add(connection3);



// add connector shapes

Aspose.Diagram.Shape connector1 = new Aspose.Diagram.Shape();

Aspose.Diagram.Shape connector2 = new Aspose.Diagram.Shape();

Aspose.Diagram.Shape connector3 = new Aspose.Diagram.Shape();

long connecter1Id = diagram.AddShape(connector1, connectorMaster, 0);

long connecter2Id = diagram.AddShape(connector2, connectorMaster, 0);

long connecter3Id = diagram.AddShape(connector3, connectorMaster, 0);

// connect shapes by index of conneecting points

page.ConnectShapesViaConnectorIndex(shape1.ID, 6, shape2.ID, 3, connecter1Id);

page.ConnectShapesViaConnectorIndex(shape1.ID, 1, shape3.ID, 3, connecter2Id);

page.ConnectShapesViaConnectorIndex(shape1.ID, 7, shape4.ID, 3, connecter3Id);

// save drawing

diagram.Save(@"C:\temp\Drawing1_out.vsdx", SaveFileFormat.VSDX);
