New Features

Grids

With the help of grids it is now easier to create certain types of graphs and diagrams. The grid automatically arrange nodes and is zoomable.

Polygonal edges

To make it possible to create more informative and good looking edges, polygonal edges can now be used.

New graph layout algorithms

Several new and exciting layout algorithm has been implemented. These algorithms can be used to position nodes (and standards Bindows components) in different patterns. The algorithms includes are:

• WedgeTreeLayout
• SingleCircleLayout
• BiconnectedComponentLayout
• HVTree

Grouping

You now have the ability to create group nodes in InfiView. The groups can have visual properties and can be expanded/collapsed. There is also Zoom Factor Dependent (ZFD) groups where its member nodes will removed from memory when they become too small due to zooming. This gives the developer new tools to handle large amount of nodes.

Printing

It is now possible to print the contents of the viewport.

Improvements

Improved Architecture

• DataContainer is now called Node
• PanelDefinition is now called Symbol
• NodeDefinition is now called Viewport
• NodeRep is now an adapter for components: Node -> NodeRep -> Component

Performance Improvements

• Better edge handling
• Less memory footprint on nodes
• Adding nodes to dynamic viewports is much faster (by factor 10)
• Creating nodes is faster
• Edge lookup for nodes is faster O(n) to O(1)
• You can now also create nodeRep from JavaScript. This is faster and consumes less memory.
• Event dispatching has improved - Less events are now dispatched causing performance gains of O(n) to O(1). When the same event is emerging from many nodes, bulk events are dispatched.

Improved Documentation

• The API documentation is much improved.
• A large selection of new documents is now shipped with the package.
• Old documents has been revamped to include changes and also improved.
• Many new sample applications has been added and old samples has been improved.
• The Xml Schema contains documentation from the API that can be viewed while editing XML.

Future Preview

Animated Edges

We have included a sample that demonstrates the upcoming feature "animated edges".

Known Bugs and Issues

Nested groups are not allowed.

A group cannot be connected to its own group.

If the visual representation of the nodes in the application are vector-graphic based, the visual representation of a foldable group must also be vector-graphic based.

Removing edges on groups has undergone limited testing.

Memory leak on restarting InfiView applications. It is odd that it leaks less after a several restarts.

oValue has no properties when restarting an InfiView application in Mozilla.

Operations made directly on the Google Maps object will not be mirrored automatically in the InfiView viewport.

Maps: There is no projection algorithms implemented in InfiView. Conversion between latitude and longitude has to be implemented by the developer that uses this development kit and are dependent on the map images used for different zoom level.

Printing of layered viewports is currently not supported.

Limitations of schemas:

• Validation is not currently supported. Basically all tags are allowed inside all tags with a couple of exceptions.
• Complex properties are not supported.
• Attached properties are not supported.
• Namespace prefixed attributes* are not supported by the schema even though they are valid constructs in InfiView ADFs.
