Well, that example is so simple. I did not generate the svg file, but you can do that with Graphics2D, direct xml, etc. It just transcodes an svg (it was only a test).
Get the code from http://people.apache.org/~baranda/baranda_webcomponents.tar.gz It is an eclipse project with everything packed inside, including a build.xml file to compile, create the jar and the example webapp. Enjoy! :-) Bruno 2005/8/4, Emmanuel Jay <[EMAIL PROTECTED]>: > Thanks for that Bruno > > So in the raster example you generate the primitive shapes on the fly > (using the normal Graphics2D I suppose), then create an SVG document using > the Batik Generator and then use the transcoder to save as JPEG or PNG and > then stream that out...
