Diagramming for ASP.NET MVC, V3.1
Apr 13th, 2018 at 3:47pm
 
We have released version 3.1 of MindFusion.Diagramming for ASP.NET MVC. It adds the following new features and improvements:

Composite nodes
The CompositeNode class implements nodes whose appearance can be defined via composition of components and layout containers. The content of a composite node can be created by building a tree of components programmatically, or by loading a JSON template. This initial release includes layout containers such as StackPanel and GridPanel. Objects from the MindFusion.Drawing namespace now double as CompositeNode components (Image, Text, Path, Rect). Future versions will add interactive components like buttons and text editors.

Animated layout
arrangeAnimated methods added to Diagram and ContainerNode classes display movement of items from their original locations to new locations assigned by the layout object. This can be used to create an explode effect by starting new layout from overlapping nodes on same position, or an insertion effect by adding a new node to an existing layout.

Export Excel files
The ExcelExporter class from MindFusion.Diagramming.Export.Excel.dll assembly exports diagrams to Excel Open XML format (XSLX) files. Diagrams are exported as Excel AutoShapes drawings. The Export overload that takes a DiagramDocument parameter creates a sheet for each DiagramPage in the document. The Export(Diagram) overload creates a single Excel sheet.

Overview improvements
  • ScaleMode enumeration and properties added to Overview control implement several scaling modes. The FitAll element corresponds to the original behavior where the Overview always fits diagram's contents. FixedScale mode applies the scale specified via overview's ScaleFactor property. CombinedScales mode multiples overview's ScaleFactor by diagram's current ZoomFactor.
  • If AllowZoom is enabled, users can zoom the diagram by resizing the overview's viewport tracking rectangle.
  • MinVisibleFontSize specifies a threshold value that hides text if scaled font sizes become smaller.

Visio2013Exporter improvements
  • Visio2013Exporter processes links' arrowheads.
  • Visio2013Exporter preserves the diagram Z order.
  • Visio2013Exporter exports links' Text and Labels.
  • Visio2013Exporter exports Image of ShapeNode objects.

LayeredLayout improvements
  • The KeepLinkShapes property of LayeredLayout lets you preserve initial Shape value of links when LinkType is set to Cascading. The orthogonal path applied by latter property is approximated using respective link shape.
  • Fix for wrong link positions when the diagram contains folded containers.
  • Fix for unnecessarily large distance between subsequent layers after a long node appears in a layer.
  • LinkPadding property added to LayeredLayout specifies how much space to leave between links when LinkType is set to Cascading.

PathFinder improvements
  • Speed of FindAllCycles and EnumAllCycles methods improved.
  • FindAllCycles and EnumAllCycles no longer report mirrored versions of cycles in undirected mode.

Miscellaneous
  • ImagePadding property of ShapeNode and Cell lets you set padding space between elements' borders and their Image.
  • Export overloads that write to System.IO.Stream objects added to PdfExporter, VisioExporter and Visio2013Exporter.
  • Non-blocking ArrangeAsync methods run layout calculations in a background task. This is only available in .NET 4.5 build of the diagram assemblies.

Installer for the latest version can be downloaded here, or from the clients area on our site:

Updated assemblies and script files are also available as MindFusion.Diagramming.Mvc NuGet package.

Enjoy!
