Support for automatic label placement

Technote (FAQ)


Question

Does JViews provide support for automatic label placement?

Answer

Since JView 5.0, a "labels layout" algorithm (IlvAnnealingLabelLayout) is available. Although it has been designed to place labels near elements (nodes and links) of a graph, it is independent from the Graph Layout framework, and can be used to position labels over geographic maps as well.

Starting with version 7.5, JViews Maps offers a dynamic map labeling mechanism that will label all graphic objects in the activated layer(s) in a separate thread. Refer to User's manual IBM ILOG JViews Maps > Prgorammer's documentation > Programming with JViews Maps > Introducing the main classes > Map-specific manager properties > Map labeling section for more information.
