Examples of org.geomajas.gwt.client.map.MapView

org.geomajas.gwt.client.map.MapView

This class represents the viewing controller behind a MapWidget. It knows the map's width, height, but it also controls what is visible on the map through a Camera object. This camera hangs over the map at a certain height (represented by the scale), and together with the width and height, this MapView can determine the boundaries of the visible area on the map.

But it's more then that. This MapView can also calculate necessary transformation matrices to go from world to view space an back. It can also snap the scale-levels to fixed resolutions (in case these are actually defined).
