Re: [udig-devel] Re: tiled rendering and labels
|
This is a multi-part message in MIME format.
Hello Again Jody,
I had a look at this issue again this morning and have a partial
solution to it. However I need to add the following method to the
RenderContextImpl.java class (and modify the getLabelPainter method
slightly)
public synchronized void setLabelPainter(ILabelPainter labelPainter){
this.labelPainter = labelPainter;
}
Do you have any objections to me adding this function?
I've attached a picture of what I have working at the moment. As you
can see the labels show up for each tile, however there are some issue
with label chopping at tile boundaries. I guess this can probably be
fixed by "meta-tiling".

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 ...
