在PS里要先把路径搞好才能导出啊///。。。

thx very much,i see.
how to use it??

There ar two major format in graph files
   one is RASTER format … BMP, TIFF, JPG, GIF, PHD  ....
   the other is VECTOR … DWG, DXF, WMF, CDR, AI .....
Translation from VECTOR to RASTER is easy,  
IN AutoCAD system Command EXPORT & SAVEIMAGE is used to save the current file as RASTER format.
But Ttranslation from RASTER to VECTOR is rather dificult.
I introduce RASTERVECT for anybody who interesting.
