Map Labeling UML Diagram
JViews Maps has a
dynamic map labeling mechanism. When activated for a specified map
layer, all graphic objects of this layer are labeled in a separate
thread. This ensures maximum responsiveness of the GUI while
performing the background layout. The labeling process is done
every time the user changes the view by zooming, scrolling, and so
on.
