MapDisplay 是一个矢量图形读取与编辑软件。我们自定义文件格式包括点、线、面、注记四大方面，对于点我们主要读取它的ID、颜色、坐标，而线另外包括线形、线宽，面则另外包括填充色，注记主要是记录ID、颜色、坐标、字体信息，对于这四方面，我们还读一个标记flag，以决定是用基本方法绘图还是用符号库来绘图。另外，为了兼容性，我们也设定它能直接读DXF文件，以处理来自AUTOCAD、Corel Draw等矢量图形编辑软件的数据。 MapDisplay的功能包括读文件并以合适大小来显示地图，并能进行放大、缩小、开窗、平移、旋转、复原、保存位图、转换文件格式、双视图互相操作、数据库查询等。 -MapDisplay is a vector graphics editor and reader software.
