The library includes all model classes and properties from MindFusion’s Java diagramming library. This provides your Android applications with access to the loaded links and nodes and their data properties, along with methods for simple hit testing from touch events. Here is a link to the online documentation of the Java diagramming component:

MindFusion diagram viewer for Android is free of charge for anyone with a license for any MindFusion.Diagramming component – you can learn more about the tools here.

We have prepared a deteiled guide on how to use the library in an Android application. You can read the tutorial from here:

Diagramming for Java Swing 4.0.1

Posted on by

MindFusion has released a new version of its Diagramming component for Java Swing with various new appearance and layout features. Here are the details:

Preserve order in tree layout

The new Balance property can be set to Preserve to keep the original geometric order of child nodes when arranging them under their parent. This can be used to arrange tree branches in a specific order by first placing them in increasing horizontal or vertical positions.

The tree layout algorithm

Undirected Path Finding

PathFinder supports undirected mode. Its methods have been changed from static to instance, and its constructor takes an ignoreDirection parameter. If ignoreDirection is enabled, the underlying graph is treated as undirected and link direction is not considered when looking for paths.

Detecting a cycle in a graph.

Selection Improvements

Miscellaneous

  • Style classes now contain a FontUnit property specifying the unit of measure of FontSize.
  • The last row in a TableNode will now be rendered clipped if it fits only partially inside the node, whereas in previous versions the row would not be rendered at all.
  • The AllowAddChildren and AllowRemoveChildren properties of ContainerNode specify whether users are allowed to add or remove child nodes to / from the container.
  • and many more.

Diagramming for ASP.NET 5.0

Posted on by

MindFusion has released a new version of its Diagramming for ASP.NET component. There are many new features for customizing the appearance, a new layout and a few enhancements. Here are the details:

Styles & Themes

You can apply now styles to change the appearance of the diagram items. Each style is a set
of properties, which can be applied to a given diagram item (with the DiagramItem.Style
property) or to all items of a specific type (by using a Theme). The theme is a collection of
styles. Each style in the theme sets the appearance of all items of a specific type. Themes
can be loaded from XML files.

Node effects
(n.a. in Canvas mode)

Two visual effects – the GlassEffect and the AeroEffect can be applied to nodes. Effects can
be added, removed or modified at any time and this reflects immediately on the diagram. You
can apply effects of different types simultaneously.

One way graph layout

This layout ensure that links enter into nodes from the same general direction and exit from
the opposite side. If the graph contains cycles some links bend around the nodes to keep the
enter/exit direction consistent. The algorithm aims to minimize the number of such links.

The One Way Graph Layout

Enhancements in Canvas mode

  • Items can cast shadows
  • Items can be Locked
  • Containers are available in Canvas mode
  • Tables are available in Canvas mode
  • Tooltips for items
  • and more

Enhancements in ImageMap mode

  • Items can be Locked
  • Interactive rotation of nodes
  • ImageFormat property added to ShapeListBox
  • and more

Multiple Labels per Link
(n.a. in Canvas mode)
The LinkLabels class allows multiple captions to be displayed for a single DiagramLink instance.
Link labels provide a set of properties that allow full customization of their location and
appearance. Labels support automatic arrangement to avoid overlapping nodes or other
labels.

Layers
(n.a. in Canvas mode)
Items can be assigned to layers and layers can be hidden, locked or moved up/down in the
Z-order or as a group. Use the LayerIndex property to associate and item with a layer in the
Diagram.Layers collection. Each layer has Visible, Locked and ZIndex properties, which affect
all items in the layer.

Parallel Layouts
The .NET 4 version of Diagramming for ASP.NET takes advantage of the Task Parallel Library
to enable parallelism on the different layout algorithms. Set the EnableParallelism property of
the Layout class to true to enable arranging different sub graphs on different threads to
improve performance on multiprocessor systems.

Magnifier
(in Java and Silverlight modes)
The new magnifier tool allows user to interactively zoom in or zoom out portions of the
diagram by holding down a magnifier tree or pressing a mouse button. The magnifier’s
appearance and zoom factor can be customized.
