Scaling Polyline w/o scaling thickness

[Niklas L]

Hello I'm scaling some Polylines, and for some I want the thickness of the line to follow the scale, works fine by default, but for some I want to keep a fixed pixel width regardless of scale. Is that possible in some simple way or do I have to calculate the StrokeThickness myself? thanks in advance Niklas

How are you currently doing this?

Oh, sorry, I'm setting a TransformGroup containing a ScaleTransform and a TranslateTransform, on the Polylines RenderTransform property. I managed to recalculate the width, but it adds a lot of overhead in adding a number of event handlers. So I'm still interested in a simpler way to do this. /Niklas

I don't know of a simpler way. My guess is that you'd need to scale/translate the polyline points separately and create a new PolyLine from those points if you want to prevent the strokethickness from getting transformed.

That's just as bad as recalculating the width I'd guess (if not worse, performance wise). Thanks for taking the time. /Niklas
