[OpenLayers-Users] KML reprojection?

[Jeremy Husmann]

Hello everyone,

 

I am in the process of adding a KML as a baselayer (I was quickly helped
by Eric and Christopher by finding the constructor attribute need for
this.).

 

Now I seem to have stuck another in relation to projections.  

 

I have noticed that if I add the KML as the only base layer it comes out
a bit squashed, when if I don't change any projection settings and just
add a WMS layer as another base layer it seems to correct the KML. -
Unsure if anything is going on behind the scenes (with my KML being
reprojected?) or if im just missing something extremely obvious. - Any
help would be appreciated.

                        var nzBounds = new OpenLayers.Bounds(165, -47,
180, -34.5).transform((new OpenLayers.Projection("EPSG:4326")), (new
OpenLayers.Projection("EPSG:900913")));
