Simone,
I am attaching a test case for you. Before you spend too much time, I
did notice as I was hacking away at my code that I left a deprecated
instantiation in:
mapContext = new DefaultMapContext();
It's on line 113 of what I am sending you. If you think that might be
the cause, let me know and I'll get rid of it and test again. I know you
guys are trying to get 2.3.0 out, and I've got other things to do, so
this can wait.
Best regards,
Amy

Ciao Amy,
could you provide a self contained test-case (or something close to it
:-) ) for me to have a look at? I am no able from the information you
provide to provide a final statement on what is happening.
Ciao,
Simone.

I'm compiling with 2.3.x and I did a straight replacement of
ReferencedEnvelope for Envelope in
StreamingRenderer.paint(|java.awt.Graphics2D graphics,
java.awt.Rectangle paintArea,
com.vividsolutions.jts.geom.Envelope mapArea). I am now getting the
following error:
Exception in thread "AWT-EventQueue-0"
java.lang.IllegalArgumentException: The provided envelope is outside the

at
org.geotools.renderer.lite.StreamingRenderer.paint(StreamingRenderer.java:636)
at
org.geotools.renderer.lite.StreamingRenderer.paint(StreamingRenderer.java:419)
Here is my code:
mapArea = mapContext.getAreaOfInterest();
renderer = new StreamingRenderer();
renderer.setContext(mapContext);
RenderingHints hints = new
RenderingHints(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON );
renderer.setJava2DHints(hints);
Map rendererParams = new HashMap();
rendererParams.put("optimizedDataLoadingEnabled",new
Boolean(true) );
renderer.paint(g2, paintArea, mapArea);
I checked to see if mapArea was getting set correctly and it appears to
be. Am I doing something wrong? I'm not sure how to use
ReferencedEnvelope, but I thought it just extended the Envelope I was
using. Any help is appreciated.
Regards,
Amy
