WebbPath shapes can be recognized by the different nodes they have. Paths in Krita are mostly bezier curves, and are made up of nodes. For straight lines, the nodes are connected by a line-segment and that’s it. For curved lines, each node has a side handle to allow curving of that segment using the cubic bezier curve algorithm.
