Description Vitaliy Lotorev 2011-05-25 13:10:06 UTC
currently zooming algorithm in Writer/Draw/Impress inconsistent and different:
in following examples zoom out performed with Ctrl+mouse_scroll_down, zoom in - Ctrl+mouse_scroll_up
Writer:
  zooming in seems to be 'stateless': it always zooms in to the very first page. It doesn't takes into account where text cursor is set or where mouse cursor is pointing. Most modern programs with ability of zooming (CADs,EDAs, map viewers, MS Word) zoom to currently editing text or to mouse cursor.
  Example: create 100 pages of random text, set text cursor to the middle of document(e.g page#50), currently we can see half of the page #50, now zoom+out to 20% and zoom in back - now we can see page#1, not page #50. 
  Yes, after hitting any arrow on keyboard view will return to text cursor (i.e page#50) but it's inconvenient and disattracts attention.

Impress, Draw:
   zoom in always to center of page.
   Example: start edit Text/rectangle by double-clicking on it or select any object, zoom in, now user sees center of page and has to search for text cursor/selected object with horizontal/vertical scrollbars which is extremely inconvenient.

Enhancement suggestion:
In Writer/Impress/Draw zoom in to currently selected objects (in case a group of objects selected - to center of the group) or text cursor.

RC2 is bit by bit identical with release version, so separate items in the version picker are useless. Changes have been discussed with Michael Meeks.

libreoffice 3.5, this issue isn't fixed

First Issue: Zooming in Writer

for me this is partly not reproducible with LO 4.3.0.4 (Win 8.1):
If I zoom in and out it stays on the cursor' page and does not switch to the first page, but the zooming focus is not on the cursor position, this means if you zoom out the cursor is not in the middle of the screen, which results in that you see more following pages, but not the preceding pages


Second Issue; Zooming in Draw

still that way reproducible with LO 4.3.0.4 (Win 8.1)


I think to solve this would be a good enhancement.
Comment 5 Rodolfo 2015-02-02 05:35:06 UTC
@vlotorev, isn't better zoom in/out using mouse cursor point as reference instead of selected objects?
I can do that.
Comment 6 Vitaliy Lotorev 2015-02-15 21:18:39 UTC
@Rodolfo, that would be great.

Please, note there is already such a bug: https://bugs.documentfoundation.org/show_bug.cgi?id=53224

Also there is a closed bug https://bugs.documentfoundation.org/show_bug.cgi?id=83588 (I didn't get into it) which shows that different devs have different opinions whether 'zooming to center' bug or not.
