全国省级及主要河流矢量地图样图(MapInfo格式)

shp演示程序 主要改正了使用点线符号（PointLineSymbol）绘制时的死机问题，并调整了几处不正确的bitmap用法。此外增加了小工具shp2esd，用来批量转换shapefile为esd文件。 把这几个目录覆盖掉1.0版的同名目录（先下载easymap1.0），重新编译就可以使用了。 -shp demo program to correct the use of the main points and lines symbols (PointLineSymbol) drawn at the time of death, and adjust the number of incorrect usage bitmap. In addition an increase of small tools shp2esd, used for bulk document conversion shapefile for esd. Several out this directory cover version 1.0 of the same name directory (first download easymap1.0), the compiler can re-use.
