问题 I have a Path in WPF and I'd like to get the single points of this path. Is this somehow possible? (I used a WPF built-in PathSegment and I'd like to get the points that WPF calculated) Thanks for any hint! 回答1: Geometry.GetFlattenedPathGeometry returns " a polygonal approximation of the Geometry object. " You can then iterate over the figures and segments of the flattened Geometry: each figure should consist of a single PolyLineSegment , from which you can iterate over the Points property to

Thus: PathGeometry g = Path.Data.GetFlattenedPathGeometry();

My problem is to measure the surface area of a path. I generate a random Path and draw it on a canvas. After touching on this closen path, i want to get the area size of this drawn path. How can i get the real area size of this path? The pathes (shapes) looks like this here: link to the image I found a solution. I generate a Region from the path and use a RegionIterator to get Rects inside the Region. With this Rects i can calculate the whole area of the path. private void calculateArea(Region region) { RegionIterator regionIterator = new RegionIterator(region); int size = 0; // amount of
