The random position generator is factored out in inteface plus separate
classes, are you interested in trying to implement
a possoid disc based one?
The objective is to generate a random distribution of points inside the
tile that will be then provided to TexturePaint for
filling polygons. The interface to implement is simple:
interface PositionSequence {
Position getNextPosition();
void lastPositionResults(boolean conflict);
}
The first method returns a x,y,rotation, the second one is called back to
notify the generator whether the generated position
was used, or stumbled into another alrady painted symbol.
You can find everything inside the RandomFillBuilder class, in the GeoTools
render module.
