Previsualization

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

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 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 ).
