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).

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  only)
  • Enhanced Windows Meta Files (EMF) (Windows, but also Linux/Unix if
    libemf is available)
  • 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)

  • Mathematica
  • via ImageMagick to any format supported by ImageMagick
  • SWF
  • CNC G code
  • VTK files for ParaView and similar visualization tools

From above cheat, we know pstoedit supports generate DXF, but it needs the help of Ghostscript or GsView

Ghostscript is the name of a set of software that provides:
* An interpreter for the PostScript (TM) language and the Adobe Portable Document Format (PDF — sometimes confused with Acrobat, Adobe’s PDF browser/editor product), and
* A set of C procedures (the Ghostscript library) that implement the graphics and filtering (data compression / decompression / conversion) capabilities that appear as primitive operations in the PostScript language and in PDF.
