Re: [udig-devel] Re: export png

Woot - now all we need to do is wrap this up as an "Export Wizard" for
an official release :-)

Alright, forget what I posted before, at least a part,
there is an easier way to get the image, instead of make all the
renderers draw on a new created image :), there is a method which I
didn't notice (do things fast, do them fast...) , which is:
RenderedImage image = activeMap.getRenderManager().getImage();
And that is it. Rendered with everything on it, I guess that takes
directly the panels graphic.
Very nice... all reduced to really few lines of code...

I just noticed that doing it that way the labels are not exported...
any idea about that?

For own usage I needed to implement a simple png export. Since
JGrass would contain it but some more time is needed to its first
release :) and since the code is really few, I paste it below. I
remember someone was interested in that, so enjoy :)
PS: is there another way to deal with the filedialog or do I have to
use the asyncexec?
