[OpenLayers-Users] Mercator projections in OpenLayers

[Arnd Wippermann]

 Hello,

I dont understand the question. I thought, Openlayers is only an environment
to generate a request to get tiles from some data provider. Of course in the
projection the data provider supports. A reprojection is not in the scope of
openlayers. I dont understand, how it will possible to reproject a map with
client javascript.

Mit freundlichen Grüssen

The maps.civicactions tile action does not support this action: the tile.js
that OpenStreetMap uses (and has become the most well maintained version of
tile.js) does support this, but does not support unprojected data.

There are no plans to create a layer which supports non-linear changes of
geographic bounds. 

It should be possible to do this in a layer subclass, and we welcome all
patches for OpenLayers.
