[udig-devel] Re: export png
|
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...
Ciao
Andrea
