Hi, Since the release of Leaflet there has been some discussion about passing default settings to a Mapstraction constructor, so that (for example) a tile set can be specified before the instance gets initialised. Has there been any official decision on this? I''ve read that Mapstraction''s stance is that each provider should be required to have a default tile set (which does make sense). But, this means business using mapstraction could incur two sets of fees for tile bandwidth (the default tile set which can''t be switched off, and the new tile set that the developer *actually* wants). Being able to override this default would be a great help Thanks for any info - andrew -------------- next part -------------- An HTML attachment was scrubbed...

Hi Andrew,
I use leaflet for mxn
here''s how we do it, I don''t believe we load two tilesets
var mxn = new mxn.Mapstraction(map_div,''leaflet'');
mxn.options.enableDragging = true;
mxn.options.scrollWheelZoom = false;
mxn.applyOptions();
mxn.setOption({defaultLayer:false});
mxn.addTileLayer(
''http://otile{s}.mqcdn.com/tiles/1.0.0/osm/{z}/{x}/{y}.png'',

I think Andrew Kirwin is correct. Leaftlet requires a basemap to
initialize. In order to keep it matching other providers we
recommended having a default load on initialization. That happens
internal the new mxn.Mapstraction constructor. You likely won''t see it
if your JS runs fast but you would likely see a request for tiles in
your Network panel.
I agree that we should either extend to provide optional arguments at
the end, or even have the constructor optionally take in an Object
dictionary and accept creation like:
var mxn = new mxn.Mapstraction({div: map_div, provider:
''leaflet'',
layers:
[''http://otile{s}.mqcdn.com/tiles/1.0.0/osm/{z}/{x}/{y}.png'']}
);
any thoughts?

Ed - what I mean is that in the background Mapstraction by default requests tiles, and then the new Tile layer requests tiles over the network. See this screenshot of the Network panel: https://skitch.com/ajturner/8tqfy/double-tiles from Andrew Kirwin''s JS example: http://jsfiddle.net/amk221/mh4Vb/1/ Ideally, we wouldn''t have to have a large object initializer, but the alternative would be to keep extending the explicit parameters. Does anyone else see an issue or solution for the initialization option to specify Tiles (and other parameters)?

As I said previously, I believe the behaviour of most of the providers is to only load tiles once setCenter has been called for the first time. I think leaflet should mimick this i.e. if no custom tile layer is added by then then load a default. If we go down the road of allowing that stuff to be specified in the constructor it needs to either call in to other Mapstraction methods to do the work or we need to amend the other providers to also support it. Don''t want to get into one set of constructor params for one provider a different set for another provider....that is not an abstraction.
