Step 2 - Install pdf2swf

  • Enable pdf to swf conversion, get more information at Application configuration > Enable PDF to SWF conversion.
  • In configuration parameters from administration there's a check button Check.png ( in older version is not used an icon is used a link called check ) that can be used to ensure your openoffice or libreoffice path are written correctly.
  • Ensure your browser has macromedia flash plugin.
  • To ensure all if fine, login openkm and try previewing some file.

Step 3 - Optional configurations

Aditional considerations about preview

OpenKM cache stores converted pdf and swf files into cache folder ( in administration configuration paramaters the parameter cache.home indicates the path used in your server ).
