            Bug ID: 452653
           Summary: (Feature Request) Smoothening of freehand line
                    annotation
           Product: okular
           Version: 21.08.1
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: shaaravgunsi at gmail.com
  Target Milestone: ---

SUMMARY
The lines produced by the freehand line annotation tool are often jagged with
pixelated and sharp curves. It would be nice if they could be smoothened after
the user is done making the line, to make it look better.
Microsoft Edge and PDF-XChange Editor both do this.


STEPS TO REPRODUCE
1. Draw a freehand line with a touchpad or mouse

OBSERVED RESULT
A small amount of 'noise' comes into the drawing, causing it to look jagged and
not nice.

FEATURE REQUEST
The drawing is smoothened by the app after the user is done drawing the curve.

SOFTWARE/OS VERSIONS
Operating System: Kubuntu 21.10
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2
Graphics Platform: X11

ADDITIONAL INFORMATION
I can provide a screen recording showing what I mean in Okular and Edge if
needed
