Public API Changes in Aspose.Diagram 5.8.0

This document describes changes to the Aspose.Diagram API from version 5.7.0 to 5.8.0, that may be of interest to module/application developers. It includes not only new and updated public methods, but also a description of any changes in the behavior behind the scenes in Aspose.Diagram.

SaveToolBar Option is added in the HTMLSaveOptions

The new SaveToolBar option has been added in the HTMLSaveOptions class. It specifies whether to save toolbar or not. The default value is true. Example codes:

 // initialize HTMLSaveOptions class object

HTMLSaveOptions opts = new HTMLSaveOptions();

// set save toolbar option

opts.SaveToolBar = false;

 ' initialize HTMLSaveOptions class object

Dim opts As New HTMLSaveOptions()

' set save toolbar option

opts.SaveToolBar = False

VSDX Saving Option is added in the SaveFileFormat

Previously, Aspose.Diagram API supported reading VSDX format, but now we have added support of writing diagrams in the VSDX format. Example codes:

 // save diagram in the VSDX format

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

 ' save diagram in the VSDX format

diagram.Save("C:\temp\Output.vsdx", SaveFileFormat.VSDX)

Group Method has been added in the ShapeCollection Class

Developers can now group multiple shapes together in the Visio diagram using Aspose.Diagram API. Example codes:

 // load a Visio diagram

Diagram diagram = new Diagram(@"c:\temp\test.vdx");

// Initialize an array of shapes

Aspose.Diagram.Shape[] ss = new Aspose.Diagram.Shape[2];

// extract and assign shapes to the array

ss[0] = diagram.Pages[0].Shapes.GetShape(1);

ss[1] = diagram.Pages[0].Shapes.GetShape(2);

// mark array shapes as group

diagram.Pages[0].Shapes.Group(ss);

// save visio diagram

diagram.Save(@"c:\temp\out.vsdx", SaveFileFormat.VSDX);

 ' load a Visio diagram

Dim diagram As New Diagram("c:\temp\test.vdx")

' Initialize an array of shapes

Dim ss As Aspose.Diagram.Shape() = New Aspose.Diagram.Shape(1) {}

' extract and assign shapes to the array

ss(0) = diagram.Pages(0).Shapes.GetShape(1)

ss(1) = diagram.Pages(0).Shapes.GetShape(2)

' mark array shapes as group

diagram.Pages(0).Shapes.Group(ss)

' save visio diagram

diagram.Save("c:\temp\out.vsdx", SaveFileFormat.VSDX)
