I've been using http://guichaz.free.fr/gliv/ http://guichaz.free.fr/gliv/ for a long time. I guess the fast hw-accelerated zooming/rotation was the hook. This one promises high-quality zooming using OpenCV, which to me sounds like it would not be hardware-accelerated. Though my PC is now a lot faster than it was a decade (or more?) ago, so maybe it's not such a killer feature anymore. I'll this this one a shot, in particular as the page for GLiv says: > Note that gliv-1.9.7 is probably the last release of GLiv. Other image viewers like Eye of GNOME are now sufficiently fast that I don’t use GLiv anymore. There will be new releases only if I receive bug reports. At first try it seems it's more difficult with qimgv to zoom into a particular region that with GLiv :/, otherwise it seems fast and fine.
