Fantastic!  I've just upgraded to 2.3.3 and I don't see this problem any more.
Great work guys, thanks!

I'm seeing large images (which don't fit) being scaled down to a tiny size
well below 75% of the available screen area.  I can't tell exactly why yet.

There is also a little oddness with some images I have which should fit
normally on the screen, but for reasons that I can't determine, are scaled
down.

My biggest use case is weather maps, which you can find at weather.noaa.gov.
These things are quite large, and when you are viewing them, you want to see
the whole thing, as large as it will go (and sometimes larger to see if a
wind speed is really 40 knots, or if it is really two 20 knots overlapping
each other).  Generally, I'll download more than one (high altitude winds,
low altitude, sea state, and 24, 48, and 72 hour predictions of each), using
a script, and then view them.

Full screen mode (F11) doesn't cut it because the scroll bars disappear, and
the image is only scaled to fit (and ctl-= no longer works).  In fact, with
some of my smaller images (non-weather), they get scaled up!

As far as window size goes, it seems to me to be a policy that should be
determined by the window manager.  75% seems like a decent size, but I'd like
to argue that if you are going to hard code a policy like this into a
program, then you should give the user the option of setting the value
including the option of being able to deactivate it.

I can sympathize with you about feature bloat, sometimes it seems that the
worst thing about open source is that good programs never reach the point
where they have fully matured; there is always some guy out there, like me,
who wants a new feature that perhaps no one else will ever use.

I mean, I could also really use hot keys for rotating the weather maps
because they like to publish some of them sideways (due to the fact that
they are really radio fax images, which have one fixed dimension (width)),
but what I'd really like is a feature more like the GIMP's which lets you
assign the hot keys yourself...

Don't get me wrong, I love EOG!  At least it has scrollbars, and navigable
controls, unlike xv.  Keep up the good work!

Cheers,

Mike
