Tkpath

Tkpath is a Tk canvas that adds these new SVG item types: path prect polyline ppolygon circle ellipse ptext group style.

Tkpath can be used as an enhanced drop-in replacement for the Tk canvas. It has also been extended to support image fills.

Tkpath now supports the use of images as arguments to the -fill option. This makes it possible to render complex shaped images. eg.
