What?
epub-thumbnailer is a simple script that tries to find a cover into an epub file and creates a thumbnail for it.
Why?
Because I want my file manager (Nautilus, Thunar, Caja, et al.) to display nice thumnails for my epub ebooks, as it does for pdf files or images, to go from this:
to this:
How to install?
Run the installer!
sudo python install.py install
Basically, it moves the thumbnailer script to /usr/bin and installs the necessary hooks:
- In gnome2, using a gconf schema (check src/epub-thumbnailer.schemas)
- In gnome3, using a thumbnailer entry (check src/epub.thumbnailer)
After installation, you might need to restart your file manager and remove cached thumbnails (~/.cache/thumbnails)
Stand-alone
This will look into the epub_file to find its cover, and will save a size px png file as output_file
epub-thumbnailer <epub_file> <output_file> <size>
