wpf - How does InkCanvas calculate bezier control points when drawing smooth paths? -


inkcanvas in wpf draws smooth curves when using touch screen when using mouse looses it's smoothness. why inkcanvas use different techniques when using mouse or touch screen?

to draw smooth bezier-curve between points seem necessary calculate put control points (one quad , 2 cubic bezier). my question how inkcanvas calculates these points when using touch screen?

i'm going render cubic bezier path mouse points (not wpf) i'm looking code calculate these control points. noticed inkcanvas suprised did differently when using mouse.
