[转]在AutoCAD中根据MapInfo导出DXF文件块属性填充图斑

现状地类有林地,159255127有林地农村居民点,255204204农村居民点望天田,255255110望天田机耕道,255180178机耕道旱地,255255183旱地果园,255223127果园河流水面,171255255河流水面荒草地,210255180荒草地坑塘水面,171255255坑塘水面裸岩石砾地,192192192裸岩石砾地祼岩地,255255255祼岩地农村宅基地,255204204农村宅基地特殊用地,255132132特殊用地沟渠,171255255沟渠工矿用地,255180178工矿用地

  第一行:"现状地类" 为Mapinfo中的字段名   以下行为具体配置,如第一行    有林地,159255127有林地  第一个"有林地"为字段里的值,后跟的9位数据为RGB颜色,后面的"有林地"是图层名,图层不存在会自动创建 配置文件名为:  d:\xdxah.ini  在程序中此路径和名称固定
