c# - WPF - How to make thickness be independent on scale? -

i draw shapes programmatically, via drawingcontext. , want shapes have fixed thickness independent on rendertransform's scale.

can it?

use drawgeometry method draw shapes geometries. apply transform transform property.

var transform = new scaletransform(...); var ellipse = new ellipsegeometry(); ... ellipse.transform = transform; drawingcontext.drawgeometry(null, pen, ellipse); 

you can modify transform after drawing shapes.
