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。
