Application to generate Java class hierarchy diagram

Looking for a tool that: - Produces a visually pleasing (not garish), orthogonally structured graph hierarchy - Outputs high-quality PNG images (300dpi+) - Visually differentiates classes, abstract classes, interfaces, and enumerated types (preferably by colour) - Interactive user interface - Allows pruning of packages and/or individual classes from the diagram - Seeds (e.g., File » Open) using a set of: - Directories - JAR files - Individual source files - Individual compiled classes - Performs a fully automatic analysis of class dependencies - Searches classpath to resolve as many unmet dependencies as possible - Uses a single executable - Is lightweight (~5MB) and fast (loads in under one second on an average 1.5GHz machine) - Is simple (under 10 clicks to generate a graph) - Is quick (graph 100 objects in a few seconds) - Is easy to use (minimal interface, focused on graph generation) - Is OSS or GPL - (Optional) Generates a call-graph hierarchy Tools that will not accomplish this task include: - Doxygen + GraphViz (or dot) - Eclipse - UML modellers - Structural Analysis for Java (cannot parse source files) - JUDE Community (awkard interface, unsuitable autogeneration) - Integrated development environments (too complex, and use too much memory) Any ideas?
