Hi Martin and others,
on my ImageJ 1.39k (Mac OSX) the magnifying glass behaves
exactly like the "+" and "-" keys for zooming.
With both methods of zooming, there is a feature that might
make it look inconsistent at the first glance:
When zooming in, ImageJ always extends the image to the bottom
and right, keeping the top left at the original position. The
window is enlarged only if there is enough space on the screen
for the enlarged window (current window size times the zoom
factor, leaving some extra space near the borders).
Otherwise, the window size remains fixed.
So an image well below half screen size will always get a larger
window by zooming in if it is placed at top left.
It won't get a larger window if placed near the bottom or right
borders of the screen.
Maybe this was the reason for the seemingly inconsistent
behavior?
Michael
