JasperAssistant is a visual report designer for JasperReports, a popular open-source reporting engine. It is built on top of the Eclipse's plug-in architecture and its main goal is to help you create JasperReports report definition files through an intuitive graphical interface.
The latest 1.1.2 version adds the following features:
Support for configurable working units. Coordinates and sizes can be expressed in pixels/centimenters/inches.
Distribute horizontally/vertically actions. Allow to evenly space a set of report elements.
Actions are now also accessible from the workbench Format menu.
Graphical engine improvements and a better support for Eclipse 3.0
Fixed a bug which caused duplicate subreport parameters to be added to the report.
