[0038] The specific implementation method is:
[0039] 1) The first step: write xml information and set the parameter information for map generation. The specification format of xml is defined as figure 2 .
[0040] Among them, the area and text tags can be defined repeatedly, each area represents an area, and text represents text remarks. The color property is to set the area background color. The linecolor and linewidth are to set the color and size of the line between regions. It is to set the area information description. The clickfunc, clickargs, clickdoublefunc, clickdoubleargs, movemousefuncs, movemouseeargss, outmousefuncs, outmouseeargss attributes are the trigger event information of the setting area. The points attribute is to set the outline information of the map. The marginleft, margintop, scalex, and scaley are to set the map zoom function.
[0041] According to the needs of Anhui, the specific definition of the xml file is as follows image 3 :...
