Hello,
I have some problems to understand the discussion.
To get tiles from any data provider I have to use the projection the data
provider supports. For WMS the BBOX must contain values, which lie in this
projection.
When I use a projection in OpenLayers, which is not supported by the data
provider, I'm not able with reprojection of the BBOX-values to get the
correct tiles. A square in one projection is not a square in the other
projection.
Therefor I must use a mapserver (when the data provider, who often support
various projections, not support the projection I want), which is able to
reproject data and send back the correct distorted (to the original
projection of the data provider) image to OpenLayers. I have to use a
program (mapserver), which is able to distort images. With Javascript there
is no possibly to do this.
When I'm wrong, please some clues so I can follow the discussion.
Mit freundlichen Grüssen
