File thumbnails

If your application handles files which could be printed or could be represented well as a document, adding a thumbnailer makes the files show up in Files with images that correspond to the document.

The gnome-desktop library defines the interface and associated files that a thumbnailer must implement. The component responsible for calling the thumbnailer is GnomeDesktopThumbnailFactory.

A common helper for thumbnailers, which handles the command-line parsing and output file generation, is gnome-thumbnailer-skeleton.
