Hi all, I know Jukka is using TMS-layer as an overlay on top of Google or what so ever layer. I think that the "overzooming" effect could be accomplished by doubling the layer's tile size and doing a little fake in order to fit 256x256 tile in 512x512 or 1024x1024 div. Maybe there are some more elegant ways to handle this, I do not know.
But if we do like I suggested, how could it be done on-fly? I know I can make this artificial client side zooming happen adding 'layer.setTileSize(new OpenLayers.Size( )) while initialising the map. But if I do it afterwards, it doesn't seem to be working. I also tried removing and adding the layer, redrawing it and couple of other things without any success. I added my tilesizing into a function which constructs the TMS-url, so everytime the zoomlevel gets over a certain limit, the tile size is adjusted. Maybe I am going wrong in this. Should I use some event handler?
