JFreeSVG 3.0

I'm happy to announce that JFreeSVG version 3.0 has been uploaded to SourceForge. JFreeSVG is a fast and lightweight API for creating SVG content in Java. This release features:

  • new handling for BasicStroke cap, join and miterlimit;
  • a new ZIP option when writing SVG to files;
  • a demo for exporting Swing UIs to SVG;
  • removal of the CanvasGraphics2D implementation (to focus on SVG only);
  • a fix for handling of PathIterator.SEG_CLOSE;
  • a fix for y-coordinate bug in drawImage();
  • a workaround for ClassCastException when exporting Swing UIs on MacOSX with Nimbus L&F.

To ensure that JFreeSVG provides a fully functional Graphics2D implementation, I tested it using the Swingset3 demo with modifications to redirect the screen output directly to JFreeSVG to produce SVG output. I've always liked the way that Swing uses the Java2D API to cleanly separate its rendering from having any direct knowledge of the actual output target. Here is an example:

SVG not supported in your browser!

This turned out to be an effective test, because it uncovered a bug in one of the drawImage() methods that has remained undetected in all previous JFreeSVG releases.

One last thing...the JFreeSVG repo at GitHub is now public, which will make it easier for other developers to tweak the code for experimentation or bug fixes (if you spot a bug though, please report it to me).

If you'd like to give feedback on this post, please comment via the JFreeSVG forum.
