Implement "biggest inscribed circle" labelling
----------------------------------------------
Key: GEOT-2822
URL: http://jira.codehaus.org/browse/GEOT-2822
Project: GeoTools
Issue Type: Improvement
Components: core render
Affects Versions: 2.6.1
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 2.6.1
For better labelling over polygon layers that present oddly shaped polygons it
would be nice to have a "biggest inscribed circle" algorithm that tries to put
the label in the widest area inside the polygon as opposed to the centre of
gravity.
This could be implemented efficiently by superimposing a grid on top of the
polygon and marking all the cells that are inside the polygon, and then
implementing a progressive "erode" algorithm that would point at cells that are
the farthest away from the polygon borders
