看到有人在论坛中询问如何把DXF格式转的PDF再转回DXF格式，可以让AUTO Cad继续修改，想到了我昨天刚下载的PSTOEDIT，本来还打算删除掉呢，今天发现它居然可以做这个工作，对我是没有什么用途，放在这里供需要的人翻阅吧。
下面就把相关的程序介绍下：
pstoedit
pstoedit is a tool converting PostScript and PDF files into various other formats suported by different drawing editors. As a prerequesite it needs GhostScript to be installed (binary installation is sufficient).
依靠Ghostscript把PostScript(PS)和PDF转成其他格式(通过插件可以支持更多格式)：
Currently pstoedit can generate the following major formats:
- Tgif .obj format (for tgif version >= 3)
- .fig format for xfig
- pdf - Adobe's Portable Document Format
- gnuplot format
- Flattened PostScript (with or without Bezier curves)
- DXF - CAD exchange format
- LWO - LightWave 3D
- RIB - RenderMan
- RPL - Real3D
- Java 1 or Java 2 applet
- Idraw format (in fact a special form of EPS that idraw can read)
- Tcl/Tk
- HPGL
- AI (Adobe Illustrator) (based on ps2ai.ps - not a real pstoedit driver - see notes below and manual)
- Windows Meta Files (WMF) (Windows 9x/NT only)
- Enhanced Windows Meta Files (EMF) (Windows 9x/NT only)
- OS/2 meta files (OS/2 only)
- PIC format for troff/groff
- MetaPost format for usage with TeX/LaTeX
- LaTeX2e picture
- Kontour
- GNU Metafile (plotutils / libplot)
- Skencil( http://www.skencil.org )
- Mathematica
- via ImageMagick to any format supported by ImageMagick
- SWF
Ghostscript
an interpreter for the PostScript language and for PDF(一个PostScript和PDF的解析器)
很多的虚拟PDF打印机程序都是依靠它来实现postscript到PDF的转换工作，开源的就有PDFCreator
安装好ghostscript 和pstoedit后，命令行的方式PDFtoDXF是：
pstoedit -f dxf in.pdf out.dxf
另外pstoedit可以做为GsView的插件来使用，至于怎么集成，中文可以看这个教程：

至于pstoedit的其他用法，各位自己看帮助，虽然都是英文，但在下水平也不怎么样，就懒得翻译了。
