Winkel Tripel projection and SVG rendering problems
---------------------------------------------------
Key: GEOT-3534
URL: http://jira.codehaus.org/browse/GEOT-3534
Project: GeoTools
Issue Type: Bug
Components: core referencing, core render
Affects Versions: 2.7.0
Reporter: Alexander Karnstedt
Priority: Minor
Attachments: export.svg, TestWinkelTripelSvg.java
Rendering a SVG with Winkel Tripel projection causes various error messages,
because the projection is not invertible. There is also a problem with
calculating generalization distances, thus produces faulty SVG polygons.
A workaround to cope with the faulty SVG is to set generalization distance to 0:
renderer.setGeneralizationDistance(0d);
Stack Trace:
