[OpenLayers-Dev] OL not suitable for raster layers?

I think we identified the source of our problems. In fact, our pixels
are probably not square. The author of both maps is one of these guys
working on global scales using ‘strange’ projections. I obliged him to
transform his maps to EPSG:4326, as demanded by the OGC standard
specifications, and the result might be an irregular pixel ratio. It
seems that MapServer5.2.1, gvSIG and ArcGIS can handle that and display
the pixels in place.
We will now see if we can get the pixels square somehow or otherwise
reproject from the original projection although I am not sure if the
latter will finally solve our problem in OpenLayers.
I will report to the list whether a simple reprojection does it or we
actually have to resample the maps.
Thanks for your time,
