public class ZGPreviewSEMA

extends javax.swing.JComponent

Bean used for the preview of a Map. This is a blue rectangular area correponding to a part of a map. Every coordinate or dimension has to be given propotionally to the map ; for example the width of the area will be given as: (width of the area in map unit)/(width of the map in map unit).
