I'm surprised, but I've seen that happen before. I suppose it depends on just how sharp the sharp edges were on your images.

Now, if someone wants to spend the time proving me wrong they are welcome to a an original scan to try it. I assume you've run something like optipng [1] over the images. I've found with complex images you can get quite a size decrease with 'optipng -o7 *.png'. However, if the size of the images at present is ok, there's no need to change anything. The quality looks fine as it is. On another note, in my tests I managed to reduce the size of the default Mapnik tiles by about 5% but I guess that reduction is small since they've already been slightly optimised. -- Matt Williams http://milliams.com [1] http://optipng.sourceforge.net ___ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
Re: [OSM-dev] Out of copyright WMS offering - looking for assistance
Alas I don't seem to bale able to make the slippy plugin work for these OOC tiles. Part of the problem seems to be that the plugin insists on downloading tiles even if I have the auto_download set to false, and secondly it seems to retry the same tile if the tile is not present and hence it just continue to retry this tile over and over again without aborting. Since we only have tiles for some areas this stops the thing working.

Since we only have tiles for some areas this stops the thing working. Hi Andy. I've been hacking on that plugin a lot lately. It's probably my fault that it ignores the auto_download thing. I'm switching all of that code over to the JMapViewer code so that we can use its caching code. That's going to necessitate rewriting the stuff that keeps track of tile sources. At the moment, I've removed the ability to add your own custom sources. I'd be happy to add your new tiles source if you can give me the URL, though. I'll also work on the jpg vs. png issue once I have some tiles that are in jpg. :) OK, well here's a quick hack to try out. It should obey the auto-loading preference if specified. You can also add custom map sources by editing your prefs file and adding entries like this: slippymap.custom_tile_source_name1=Mapnikcopy slippymap.custom_tile_source_url1=http://tile.openstreetmap.org You can add several as long as you end the names with 1, 2, 3... Here are the jars: http://daveh.dev.openstreetmap.org/josm/20091018/ I'll give it a try, thanks. Does anyone care about having a gui to add custom sources? I'm not sure how common it is for people to need that. Mostly these can I think be hard coded as and when they come up (or for the hardened mapper added manually). Mostly a new set of tiles are only going to come along periodically I'd have thought. -- Dave ___ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev

Hi folks, You are perhaps aware that we have some more out of copyright mapping available (for the UK) and that the set-up on the new dev box will permit other out of copyright map series (extensive areas rather than individual maps) to be tiled and uploaded similarly. There is one small fly in the ointment currently in that TimSC's WMS code (php) is currently set up to work just off z14 tiles. For the 1:25,000 scale mapping I've been uploading I'm creating z15 and z16 tiles. These work fine in potlatch but because the z14 tiles are being used for the WMS, JOSM users are missing out on all the lovely detail. There is also the wish to get the code using the various zoom tiles appropriately across the range as each map series is likely to have a different zoom range available. TimSC is tight for time to look at this but happy to answer questions, so we are looking for anyone else who fancies a challenge to get these great new map tiles available for JOSM users (and other map series as they come along).
