[Opensource] Printing using 2D graphics

[David Herron]

Jeff,

Maybe the JFreeReport package is what you're looking for.  (There's also
JasperReports that does similar things).  Both are open source projects
that you can find by doing a search.

You might look at JEditorPane along with HTML to do the formatting.  Since
it is a lightweight Swing component, it can be rendered to a BufferedImage
in Headless mode.

a) run Java with -Djava.awt.headless=true
  This blocks off all attempts to reach a graphics device, and does
  so in a programmer-friendly manner so that a programmer can easily
  write graphics oriented code and have the code easily and clearly know
  whether it's in a GUI or off-screen environment.

b) make a BufferedImage

c) get it's Graphics

d) make a component hierarchy including JEditorPane.  Fill it with
  your HTML.  Call paint(graphics).

e) The BufferedImage then has whatever-you-want rendered into it, and
  you can do whatever you want with it.

Have fun,

	David Herron
