Hi again,
here's another little (haha, took hours) thing: I created an
openraster-thumbnailer based on cover-thubmnailer (well, I stripped out
a lot of things), that means, gnome/nautilus people will be able to see
.ora previews on their desktop / in their browser windows. I attached
the files needed for this (openraster-thumbnailer and
openraster-thumbnailer.schemas), but I haven't created an installation
script, yet.
However, here are the instructions:
sudo cp openraster-thumbnailer /usr/bin/
sudo chmod +x /usr/bin/openraster-thumbnailer
sudo cp openraster-thumbnailer.schemas /usr/share/gconf/schemas/
gconftool-2 --install-schema-file
/usr/share/gconf/schemas/openraster-thumbnailer.schemas
gconf-schemas --register
/usr/share/gconf/schemas/openraster-thumbnailer.schemas
(but I'm unsure if that last step is needed)
Then simply restart nautilus (e.g. "killall -9 nautilus") and it should
create thumbnails for .ora files. If it doesn't, you might need to append
image/openraster ora
to /etc/mime.types
If anyone's good at packaging or writing install-scripts, please let me
know. I'd be glad to be able to upload .deb files to my launchpad PPA so
that at least ubuntu users can easily install this script.
If there are archlinux users out there, I think it won't be too hard to
upload it to AUR or so.
Thanks
Till
P.S.: It still needs proper testing, though ;)
