Low level development of map symbol library under logical classification system
WU Guang-che · 2014
Currently,map symbols are made usually by using existing symbol library system or secondary development,leading to the symbols with poor scalability,so it is important to make low level programming of symbol library.With the GDI+,the paper designed a low level programming scheme of symbol library under a logical classification system,which includes map symbol classification and attributes design,low level class design of symbol library and symbol library construction.In the long run,it would have strong practicality and scalability of the low level symbol library system by GDI+.
