JFDraw is a pure Java based graphics application and library package. JFDraw used a little features of Java2D, and expanded a lot of graph routines for more complex vector graph processing. You can run JFDraw under any operating systems that suport Java.
JFDraw is focused on vector graph drawing field. It can help you to complete your mechanical, electronic, architectural graphs drawing applications, or even business process or workflow graphs issues.
Written by pure text based editor(Windows NotePad & Unix VI), built by Sun Java Development Kit(JDK) 1.3.x and Apache Ant, JFDraw will offer you the opportunities to incorporate it into your graph applications, in binary library mode or source code mode.
a variety build-in vector graphs, e.g. rectangle, triangle, parallelogram, trapezoid,polyline, regularline(continuous vertical or horizontal line), etc.
automatic nodes combining or expanding in polylines and regularlines, it's needless to add or remove a node for drawing such poly lines.
easy to use adding/removing/binding/unbinding ports functions, for help doing ports issues(ports are used to connect shapes by lines) on arbitrary shapes.
a lot of arrow types, fill styles and line styles, so you can easily change your shapes' appearance to fit your demand.
goup/ungroups, multi-layers, customized libraries and templates support.
roate, flip, mirror and scale functions on any shapes.
zoom in/zoom out or customized zoom scale, undo/redo with arbitrary undo depth.
grid, ruler support with both english or metric measurement.
binary/xml JFDraw build-in file format, export to jpg, png, svg and more file formats.
