Previsualization

To take OpenKM previsualization should configure several applications that are used for OpenKM by this purpose.

To preview documents is mandatory your browser have installed flash player, ensure you got it installed

Configuration has two main steps:

Step 1 - Install OpenOffice or LibreOffice

• In Third-party software integration: OpenOffice.org is explained relevant information about how doing it Third-party software integration: OpenOffice.org and Application configuration > Enable OpenOffice.org integration
• In configuration parameters from administration there's a check button ( 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.
• After configured and tested openoffice / libreoffice is installed is needed restarting OpenKM, because OpenKM will automatically starts soffice service on startup time.
• To ensure all is fine, login openkm, select some document convertible to pdf, and using Toolbar download document converted to pdf.

Configuration test:

Log server indicating soffice service is started:

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 ( 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

• Enable ps to swf conversion, get more information at Application configuration > Enable PS to SWF conversion.
• Enable preview images, get more information at Application configuration > Enable image preview.
• To ensure all if fine, login openkm and try previewing some file.

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 ).
