Hi. I wrote a render script that (similar to the compositing that hike&bike map does) does things that mapnik is not capable of. My script is written in python and can render bboxes into arbitrarily sized images, as well is able to serve tiles (e.g. http:localhost/bla.../12/345/678.png) However it is probably the utmost slow renderer there is, it takes about 3 minutes for a simple tile. (Which is ok, because it's experimental only at the time. :)) How can I make renderd (or tirex, or tilecache) call that script, I found no documentation on that. I want to create metatiles of course, too, because I have a thin lines of garbage at the tile boundaries. Can you please give me a hint/link on how/where to start? Thanks a lot, Kay
