Layer.WMS: use layer.projection

[fredj]

Layer.WMS uses the map.projection object, the layer.projection should used instead.

Replying to fredj:

Layer.WMS uses the map.projection object, the layer.projection should used instead.

Are you sure? What if the base layer and the layer in question use a different projection? Then Layer.WMS will request tiles in the wrong srs.

[fredj]

But why do we have a projection property in the base class ? Is it only applicable with non raster layers (WFS, GeoRSS) ?

[ahocevar]

If the layer is a base layer, the map will take the projection from it. This is the original purpose of layer.projection. For layers that can be projected, it is used for reprojection. But this is a more recent use of layer.projection. And for Layer.WMS, we cannot reproject, so we have to request tiles in the map projection.

ok, thanks for the explanation.
