Hi,
I have been trying unsuccessfully to convince Nautilus to display thumbnails of
tgif (*.obj) files. I repeated the steps given in Romano's blog:
http://rlog.rgtti.com/2011/11/24/xfig-thumbnailers-with-gnome3nautilus3/ and
created files: /usr/bin/tgif-thumbnail (with executing permission) and
/usr/share/thumbnailers/tgif.thumbnailer -- their contents is below. The
xdg-mime confirms that the type of *.obj files is application/x-tgif. In
gconf-editor I can see that
/desktop/gnome/thumbnailers/application@x-tgif/command is set to
"/usr/bin/tgif-thumbnailer -s %s %u %u" and
/desktop/gnome/thumbnailers/application@x-tgif/enable is checked. Calling
tgif-thumbnailer manually:
tgif-thumbnailer -s 128 file://myfile.obj myfile.png
produces a little PNG image in the current directory. But still no thumbnails,
only generic icons in Nautilus. Does anybody have a suggestion what else should
I do? Thanks for your time and help!
