            Bug ID: 366781
           Summary: Implement zooming with a pinch gesture on a touch
                    screen
           Product: okular
           Version: 0.25.80
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: oliver.sander at tu-dresden.de

The attached patch implements document zoom controlled by a two-finger pinch
gesture on a touch screen.  Can somebody please have a look at this?  The
actual zooming was done by copy'n'paste, I don't understand the full details of
how zooming works in okular, yet.

I tested it on my Lenovo Thinkpad Yoga, and it works nicely.

The patch needs some infrastructure from
https://git.reviewboard.kde.org/r/126809/ 
On request, I can easily extract that infrastructure into a separate patch, or
include it with this one here.

Unfortunately, I can't get ReviewBoard to accept the patch file.  The error
message is

"The uploaded diff uses short revisions, but Review Board requires full
revisions. Please generate a new diff using the --full-index parameter."

And when doing as told, I get 

"The specified diff file could not be parsed.
Line undefined: fatal: git cat-file 36b31779250246b13f1096f0af443027058d989e:
bad file "

Any ideas?


Reproducible: Always
