Andreas, the code does work but only after applying your patches. There was no way for application to "solve" the problem by splitting geometry without them. Also the patch is making an assumption about 179 0, -179 0. If extent is across dateline, then the joining line you would make with say the path handler crosses the dateline, rather than going around the world (which is what it used to do). > You may want to try the SVG2 renderer I am currently working on.

However, this must make assumptions on line directions for 179 0, -179 0 if you are doing this at this level. For the moment, I am working with your patches and seeing what are the unresolved issues. I had next to no time on this over last few days but should be able to get back to it this afternoon. -- Phil Scadden, Senior Scientist GNS Science Ltd 764 Cumberland St, Private Bag 1930, Dunedin, New Zealand Ph +64 3 4799663, fax +64 3 477 5232 Notice: This email and any attachments are confidential.
