Hello,
I'm using Processing 2.2.1 with the latest version of the Unfolding library on a Win 7 box.
The problem is the following :
When running most of the examples, I get a black map (or unzoomable and making glitches when panning), and the processing console fires a lot of messages complaining that :
The file "http://a.www.toolserver.org/tiles/bw-mapnik/13/4095/2726.png" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.
or..
The file "http://tile.stamen.com/toner-background/12/1236/1516.png" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.
I think the a.toolserver.org
mentioned in the first error message is the OpenStreetMaps
default provider's server.
So, I went to the a.toolserver.org
to see if, by chance, it was down or something. Instead, I got a (not so) pretty page saying that "We've Moved", along with the following message :
We're sorry, but the user-supported tool you have attempted to reach
did not leave a forwarding URL where we could automatically redirect you.
So I said to myself that maybe was the problem.
But the URL mentioned in other error messages (like the second one here http://tile.stamen.com/toner-background/
did not work either.
So.. I ran all the examples and this happens with most examples, except the one using the Microsoft.AerialProvider (which seems to work correctly), or certain Stamen providers :(
I have a project to code involving heavy use of Unfolding so if you gurus out there have an idea, please help me out !
So all you code gurus.. @codeanticode , @amnon , @poersch , @gotoloop, and you @tnagel, please help me on this one :)
Thanks in advance and merry Christmas !

Ok, might be two problems. The general one is that OpenStreetMap's tool server moved to a new location where the respective team did not set up the bw-mapnik tile provider anew. Meaning, Unfolding's default map provider is not working anymore.
Please see https://github.com/tillnagel/unfolding/issues/100
I try to release a new version with another default provider early next year ;) The work-around for now is to use another map provider. http://unfoldingmaps.org/tutorials/mapprovider-and-tiles.html#map-styles
Regarding the second problem (the Stamen map also not working), I wonder if this is unrelated. When I click on your link it works for me. If it does for you too, maybe check whether Processing can access the web at all.
Thanks a lot @tnagel ;)
The Stamen problem is now resolved, and I've changed the default provider on all the examples to various providers and it works... fine !! ;)
One more question : are you going to update the library, when the
OpenStreetMaps
provider will be working again so we can use tiles from OpenStreetMaps ?Thanks for your time (and for the GREAT library !)
Hi, I want to use unfolding Maps.
If I use the example SimpleMapMarker, the App crahes after start with this information: FATAL EXCEPTION: Thread-9366 java.lang.NoSuchMethodError: processing.core.PApplet.loadImage at de.fhpotsdam.unfolding.tiles.TileLoader.getTileFromUrl(Unknown Source) at de.fhpotsdam.unfolding.tiles.TileLoader.run(Unknown Source) at java.lang.Thread.run(Thread.java:841)
The error is the same if I use various Map Provider from: http://unfoldingmaps.org/tutorials/mapprovider-and-tiles.html#map-styles
Any suggestions?
@DennisEB : That must be a version problem. Download and install latest version of Processing and Unfolding and it should work.
BTW : this question has nothing to do with the original and you should move it to a new thread.
