Refresh Data of Connected Visio Shapes

The recent version 17.6 of Aspose.Diagram API allows refreshing the data of shapes, including XForm, TextXForm, Connection, and Geoms after changing the text or position of the connected shapes. When there are many changes to the ShapeSheet data and developers want to recalculate the connected shapes in a drawing. They can call the RefreshData method of each shape instance as below:


// load diagram
Diagram diagram = new Diagram(@"c:\temp\Drawing1.vsdx");
// retrieve page by name
Aspose.Diagram.Page page = diagram.Pages.GetPage("Page-1");
// retrieve shape by ID
Shape shape = page.Shapes.GetShape(12);
// save diagram
diagram.Save(@"c:\temp\Drawing1.vsdx", SaveFileFormat.VSDX);


// load diagram
Diagram diagram = new Diagram("c:\\temp\\Drawing1.vsdx");
// retrieve page by name
com.aspose.diagram.Page page = diagram.getPages().getPage("Page-1");
// retrieve shape by ID
Shape shape = page.getShapes().getShape(12);
// save diagram"c:\\temp\\Drawing1.vsdx", SaveFileFormat.VSDX);

Besides this, the mechanism of storing and retrieving text elements in the Visio drawings has been improved. The recent version also comprises a series of bug fixes. In general, it improves the export of Visio drawings to SVG and image formats as well as preserves formulas in the shapesheet.
