[josm-dev] Walking Papers Plugin

[Frederik Ramm]

Hi,

    I have committed a new and rather experimental "walking papers" plugin.

For those who don't know what Walking Papers is (www.walking-papers.org, 
don't forget the dash or you end up with some nutcases): A web site 
where you can print out a map and, after scribbling on the printout, 
scan it and upload it and have it delivered to you as slippy map tiles.

I used Lubomir Varga's Slippy Map plugin as a basis. I first wanted to 
add functionality to the Slippy Map plugin but it turned out that what 
Walking Papers needs is a bit different, mostly because for each Walking 
Papers ID you will want a slippy map layer of its own.

When you load the plugin there is a new entry in the main menu, and by 
clicking on that you can create a new Walking Papers layer. This 
requires entering the Walking Papers ID, for example in

http://walking-papers.org/scan.php?id=bdtgnkvs

the ID would be "bdtgnkvs".

The plugin still has some weaknesses, most notably that it does not 
properly detect the area for which Walking Papers has computed tiles, so 
it will try and download tiles all the time if you zoom to another area 
on the map. To find out where I have to zoom for displaying a specific 
ID, I actually have to screen-scrape the URL above... I'll try and find 
out if there is a better way. Potlatch seems to support it just fine.

I haven't yet committed the .jar file so I hope the plugin will not show 
up in JOSM automatically - you'll have to build it yourself. If anyone 
wants to make any improvements, you're more than welcome to do so ;-)

Bye
Frederik
