We have released version 1.4 of Xamarin Diagram control. It contains the following new features and improvements:

JSON Serialization
Diagrams can now be serialized in JSON format. This can be used for interoperability with MindFusion JavaScript diagramming library, or for general storage in JSON files or databases. To serialize a Diagram to a JSON string, call its SaveToJson method. To deserialize a diagram back from its JSON representation, call the LoadFromJson method. Custom item classes can implement JSON serialization for their additional properties by overriding the SaveToJson and LoadFromJson methods of DiagramItem. Such classes must be registered for serialization by calling the RegisterItemClass method and providing a string identifier for the clientClass parameter.

Miscellaneous

• RadialMenu improvements.
• ZoomToFit method added to DiagramView.
• Interactive pinch zoom in UWP.
• Various SaveTo* methods are now async.
• XML serialization improvements and fixes.
• LongPressed event added to Diagram.
• StringFormat.ClipText property and wrap fixes.
• Fixed arc segments in UWP graphics paths.
• Fixed a bug which caused the diagram to not show on initial load in a UWP application.

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