To facilitate interaction with security frameworks like SELinbux and AppArmour, it is even better for the mgmt app to just be able to pass a pre-opened FD across the monitor, rather than using UNIX sockets. > The last 3 patches add support for dumping in PNG format.

We can let it guess format by default, but we should provide a way to force the format via an optional arg. > Next, I would like to add support for a scaling factor too (a typical > use case is to show a small thumbnail of the desktop).

My suggestion would be to use Gdk-Pixbuf, since that also gives you support for saving to arbitrary file formats, as well as scaling, etc. Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|
