It has been a few years since I have worked with geotools, it is taking a
while to absorb all the api changes.
I am trying to output my work using the StreamingRenderer but all I seem to
output is a blank image.
Here is a link to my code:
https://github.com/mores/maven-examples/blob/master/gis/src/test/java/org/test/AppTest.java
What am I missing ? Why aren't my points getting rendered ?
-Thanks
