Description Allison Karlitskaya (desrt) 2005-09-03 21:37:36 UTC 
evince should have an eog-style UI mode where you have these semantics:

  - scroll wheel zooms in/out (scrolling is sensitive to location -- if you are
pointing at a specific region of the document and scroll up then you zoom it to
that region).  similarly, if you're zooming out then it's done in such a way
that the position of the mouse cursor doesn't change with respect to the document.

  - click+drag moves you around in the document


for certain types of documents, this navigational mode is absolutely amazing
(large detailed maps, for example)

Scroll wheel will zoom out with Ctrl pressed, click on button 2 should start drag

I understand that such things are not easy discoverable, but isn't it enough
that they exist?
Comment 2 Allison Karlitskaya (desrt) 2005-09-03 22:22:46 UTC 
I didn't know about this.  Thank you.

The scroll in/out behaviour doesn't have the nice properties (listed above) that
eog's has, though, so I think this bug should remain open (but I will change the
summary)
Comment 3 Marco Pesenti Gritti 2005-09-22 15:41:55 UTC 
I dont know if the position of the mouse shouldnt change. I tend to think it's
more important that document position doesnt change in respect to page bounds.
Try to change zoom with the zoom control to see what I mean.

Now I'm not sure why this doesnt work for mouse wheel scrolling. nsh any idea?
Comment 4 Allison Karlitskaya (desrt) 2012-01-19 03:24:25 UTC 
This bug still exists: the zooming is not impacted by the position of the mouse cursor.
Comment 5 John Beard 2016-04-22 11:13:48 UTC 
This seems to now work on git master (3.20)? When I Ctrl-scroll-up at with the mouse over the top of a page, that is what is zoomed in on, and if I scroll out and move the mouse to the bottom and zoom in again, _that_ is what is zoomed in on.
