Description Shaarav 2022-04-15 10:50:06 UTC 
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.

ADDITIONAL INFORMATION
