ZoomOut

Unit:SDL_geoatlas
Class:TGeoAtlas
Declaration:function ZoomOut (CurrentLat, CurrentLong, CurrentResolution: double): boolean;

Calling the method ZoomOut has the same effect as pressing the right mouse button while the property ZoomButton.Down is true. The position specified by the parameters CurrentLat and CurrentLong must be contained in the new map. The parameter CurrentResolution specifies the resolution of the current map (in meter/pixel). The function ZoomOut returns TRUE if a map has been found (and displayed) which offers a resolution worse than the current one; otherwise a FALSE value is returned.
