open_dxf_lib

open_dxf_lib 打开的库，用于读取和写入.dxf文件（与AutoCAD兼容）。 这样很好，很容易： ... DXF_file f = new DXF_file ( Mode . Open_file , " /home/mydxf.dxf " ); Color_dxf c = new Color_dxf ( 255 , 255 , 255 ); f . put_text( 100 , 50 , 450 , 0 , 0.5 , c, " text in dxf file " ); f . put_arc( 250 , 300 , 50 , 120 , 360 , c, 4 ); f . put_circle( 400 , 300 , 50 , c, 4 ); f . put_line( 0 , 320 , 100 , 50 , core.dash_type .
