Hi Simone,
We actually already have a tile rendering system in place with uDig. We
have also added support for uDig to use WMS-C tiled servers. So we are
already retrieving tiles from a GeoWebCache server. Right now we are
simply keeping some of these in memory as the user pans around. I'm
really just looking for a simple way to write images to disk and was
wondering if uDig had a common API for doing this already.

Ciao Graham,
I am extremely interested in what you are talking about, for a simple
reason, I would like to do something like that for building piramids
on the fly and store them outside the original file when accessing
large raster with no native overviews.
I think the best thing you can start from in geotools is Jody plugin
for tiled sources (which I think you might be already using). However,
looking at the bigger picture I would urge you to consider an
integration/reuse of the backend of GeoWebcache to achieve this task,
which some modifications of course.
I think that with some good old thinking + collaboration we could
share the same engine for various purposes.
Simone.

Hi all,
I'm looking to store some tile images on disk so they can be easily read
later. I'm picturing tiles being grouped by layer name and scale so there
will be tree directory structures to hold the tiles. I haven't done much
work with writing to disk within uDig or GeoTools and was wondering if there
are any classes or APIs commonly used for this sort of stuff? Are the
general Java File classes usually used, or is there something better? Any
suggestions? Thanks,
