Description GeeKen 2012-07-25 11:32:19 UTC 
Problem description: 

As long as I remember in Open Office and in LibreOffice, when using DRAW, the Zoom slider at the bottom right of the screen can be used as an Input to control Zoom.

However its scaling ("Gain") goes insanely large after 100%, making it unusable.

Steps to reproduce:
1. .... Just use the Zoom Slider to Control Zoom!!
2. ....
3. ....

Current behavior: 

1) Gain of Zoom Slider is non-linear and far too high, after 100% Zoom.

2) Slider is too short to be easily used.

Expected behavior:

1) Gain of Zoom Slider is usable & linear, like a mouse does to the pointer on the screen of any Operating System.

2) The Zoom slider is made 3+ times longer than it is, with a more bold 
"% Zoom number", so this can be used for fine and stable control of Zoom.

Even if it is stepped to 10% Zoom intervals, thats AOK.

Thanks

I can confirm this bug in version 3.5.6.2. The zoom factor seems to increase exponentially. On the lower end, we have 2 cm (on my screen) to zoom from 8 to 100 %. after that, 1 mm increases zoom from 100 to 400 %!
Unfortunately the plus and minus buttons are useless as well, because they change the zoom factor by only 5 % points with each click. Zooming from 100 to 200 % is impossible. The maximum of 3000 % is also rather extreme.

I agree with this bug report.  It is a major usability defect.  It is the one factor that makes me think twice about using OO for drawings.  No other drawing tools have this level of problem with the zoom control.

This bug can still be reproduced in 5.x.
Comment 5 Henrik Mantke 2016-02-01 17:26:33 UTC 
I am working on this bug. 

The problem is not an exponential. The zoom changes linear with the slider position in two parts. The first part goes from 1% to 100% and occupies the first half of the slider. The second part that occupies the second half of the slider goes from 100% to max zoom. For draw and impress this means 100% to 3000%. Therefore this part has a very high constant slope. In combination with the snapping point, that turns the zoom to 100% again, if you move the slider very little it is impossible to reach zooms between 100% and 200% with the slider.

Zoom example with 120% sized document

I don't know if that's the same or related but: 
If we open 120% sized document, it's not at all obvious how to size it back to 100%. In this case, it's almost clicking in the same line, which is not well seen.
This 100% zoom bar should be more visible, thicker and higher, if possible.
