Load a VSS Template to Create a Visio® Diagram with C# Code

You can execute the below code snippet to see how Aspose.Diagram API performs in your own environment or check the GitHub Repository for other common usage scenarios.

// create a new diagram
var diagram = new Diagram(dataDir + "template.vss");
// add a new rectangle shape
long shapeId = diagram.AddShape(4.25, 5.5, 2, 1, @ "Rectangle", 0);
var shape = diagram.Pages[0].Shapes.GetShape(shapeId);
shape.Text.Value.Add(new Txt(@ "Rectangle text."));
// add a new hexagon shape
shapeId = diagram.AddShape(7.0, 5.5, 2, 2, @ "Hexagon", 0);
shape = diagram.Pages[0].Shapes.GetShape(shapeId);
shape.Text.Value.Add(new Txt(@ "Hexagon text."));
// save the diagram in VDX format
diagram.Save(dir + "output.vdx", SaveFileFormat.VDX);

Retrieve Layers of a Visio® VSDX Diagram

Aspose.Diagram for .NET allows .NET applications to work with layers of Visio® drawings. The following C# code example shows how to fetch all the layers of a VSDX file:

// load source Visio® diagram
var diagram = new Diagram(dataDir + "Drawing1.vsdx");
// get diagram page
var page = diagram.Pages.GetPage("Page-1");
// iterate through the layers and print properties
foreach(Layer layer in page.PageSheet.Layers) {
  Console.WriteLine("Name: " + layer.Name.Value);
  Console.WriteLine("Visibility: " + layer.Visible.Value);
  Console.WriteLine("Status: " + layer.Status.Value);
}
