Release 4.0.0

Overview

Tom Sawyer Perspectives introduces an advanced data-driven graphics architecture that offers a flexible run-time approach. The drawing canvas background, nodes, edges, connectors, and labels each can have rich attributed graphical decorations. Customer applications can provide graphical drawings with "level of detail" support, enabling the end user to expose additional graphical detail as zooming thresholds are passed.

The drawing canvas now supports new hover, select, and highlight metaphors. New precise shape clipping improves drawing resolution.

Also, for large drawings with thousands of nodes, layout performance is markedly improved.

Additionally, a timeline view shows events in chronological order, for use in link analysis applications. A new path trace view supports network management applications. New blinking graphical decorations support network monitoring applications.

This release supports Eclipse SWT, and offers integration with Objectivity InfiniteGraph and Google Earth.
