Re: [OSM-talk] New static-maps API - relations
You can now view relations using the Static Map API. e.g. here is one of the underground lines in OSM: http://tinyurl.com/mjcd7o The equivalent slippy-map view is at http://tinyurl.com/klkrkl and its main page http://dev.openstreetmap.org/~ojw/relation/ will let you enter a relation ID. To get the relation ID for something, try copying from a potlatch edit session, or look the wiki for some interesing examples. Currently this website only shows 'route'-type relations, and only shows ways (not nodes or hierachical relations) regards, OJW p.s. I'm still trying to figure-out transparency in GD. Anyone know how to put a semitransparent line on a transparent background, and save the result as PNG? ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] New static-maps API - relations
If my memory is correct you first do a createcoloralpha(r,g,b,a) where r,g,b a are 8 bits values but I don't remember if 0 is full transparent or full opaque. You then use that color as usual. You may have to first create a fully transparent color and use it to fill the entire image otherwise the resulting image ends up opaque. Yann Le 7 juil. 09 à 23:56, OJ W a écrit : p.s.
