Is it possible to find intersection area?

[victoriaSh]

Just a question. I have Paths with strokeWidth. I want to find area of grey and black paths (on screenshot) and compare it to their intersection area to detect that user draw a letter.
Intersection of paths doesn't include information about strokeWidth. it seems that converting path to rectangle will not work for curved paths.
Is it possible to find intersection area with kdl-intersection package?

I would rather render both letters to a bitmap and compare them pixel by pixel. Assuming, that you want to calculate some kind of similarity score.

If you wish to calculate how well a kid writes, then go with completely different approach: compare strokes, not the intersection with the template. Imagine the drawn A is just a little bit bigger than the template. The two (almost) vertical strokes are both just next to the template. Therefore, the grey area is huge, but the kid created almost a perfect letter.
