Re: [udig-devel] Re: tiled rendering and labels

The attached image shows another issue with tiled rendering that I currently know about. In this image the blue line is the tile boundary.

The problem occurs when you have a geometry whose actual position is on one tile but whose style says it should be on a neighboring tile as well. Other than rendering some sort of buffer around the tiles I'm not sure how to fix this issue either.

Yes Jody, you are correct. Labels and tiled rendering do not work well together. I looked into this briefly at one point but I didn't find a decent solution. I believe what we are going to need is one label renderer for each tile rather than just a single label renderer.

I may have some time over the next few weeks to look at this further. Not sure at the moment.

Hi Emily: This may be another corner case; I was testing out tiled
renderer with the "climate change intergration showcase" dataset for
foss4g this year. And labels went absolulty bonkers... this test is
with the last udig 1.2-M3 release and does not reflect any recent work
you have done.

Near as I can tell the label cache implementation is not being reset
on a tile by tile basis; you may even wish to store a tilecache in the
render context you create for each tile? I am not sure how it should
be done ...
