While OpenOffice.org has internal support in the Windows desktop integration for the system file browser, providing thumb previews of OpenOffice.org files (see source code), such a feature is completely missing in its KDE integration.
The idea here is to develop a plug-in for KDE file managers (Dolphin and Konqueror) to preview OpenOffice.org files (Open Document Format) as thumbnails. Although this could be integrated into OpenOffice.org source code, I find it better to distribute the plug-in as a KDE extension, because it is developed using only the KDE API, and so it does not need OpenOffice.org to be installed for it to work.
Features
- the plug-in only works for Open Document Format files (the default file format since OpenOffice.org 2), not the old binary file format
- the plug-in only creates a thumbnail when the OpenOffice.org document already has a thumbnail file (ODF files are zip files, the plug-in searches for the Thumbnails/thumbnail.png file inside it). This means that there is no thumbnail preview for OpenOffice.org Base files (or in case the ODF file has no Thumbnails/thumbnail.png, or the thumbnail.png is corrupted)
- when the document is digitally signed, the plug-in reflects this fact by painting a signet on the upper right corner of the thumbnail. This is done slightly different from the way OpenOffice.org does it in its Windows integration:
Notice that there is no check at all about the digital sign validity: the plug-in only looks for a META-INF/documentsignatures.xml file, which only indicates that the document is signed.
- transparency is handled properly by removing the alpha channel (Note that although I thought it was an OpenOffice.org feature, the transparency on the thumbnail.png file is a bug: see issue). The plug-in will keep the check for alpha channel so that it can work with old files created before the issue fix.
Where to download
The plug-in has its page on KDE-Look.org:
