Description Hakon 2002-08-31 11:31:14 UTC 
If you open a picture in eog, and it's too large to displayed 100% within
the desktop, it will open as 50% or so... But if you use the scrollwheel on
the mouse to zoom, you may wind up at 99% for example. I think it should
always be rounded off to exact zoom levels, like 100% ; 200% etc. since
those produce the most correct display.
Comment 1 Hakon 2002-08-31 14:18:10 UTC 
Well, actually, I don't think this problem occurs if the window is
initially zoomed to 50% but if it is 33% then it becomes obvious.
Comment 2 Federico Mena Quintero 2002-09-12 00:29:05 UTC 
It is not a round-off error.  The zoom factor changes by a constant
multiplier (1.05) in the source.  This produces the most pleasant
effect when zooming continuously.
Comment 3 Hakon 2002-12-24 01:11:04 UTC 
Okay but what about always have zoom:100% as index:100 then?
The current behaviour is probably that index:100 is the initial
display when you open a file, even if it is at zoom:33% in order to
fit the screen.
Comment 4 Jens Finke 2003-04-09 14:57:39 UTC 
The current behaviour is as follows: 

+/- keys: smooth scrolling, which may end up with 99%.

STRG++/STRG+- key combinations: indexed zoom, which changes in
predefined steps. (50%, 100%, 200% ...)

This seems good to me.
