35 | * There are two different layer types: |
||
36 | * - MapLayer: Displays Maps, but also Geometries. The configuration for displaying maps have to be done in the MapAdapter |
||
37 | * - GeometryLayer: Only displays Geometry objects. |
||
38 | * |
||
39 | * MapLayers also can display Geometry objects. The difference to the GeometryLayer is the repainting. Objects that are |
||
40 | * added to a MapLayer are "baken" on the map. This means, when you change it´s position for example the changes are |
||
41 | * not visible until a new offscreen image has been drawn. If you have "static" Geometries which won´t change their |
||
42 | * position this is fine. But if you want to change the objects position or pen you should use a GeometryLayer. Those |
||
43 | * are repainted immediately on changes. |
