With Construct2 you should probably use the SVG plugin
since according to this (old) thread
SVG is an alternative to the canvas itself.
Be aware that by default, C2 doesn't support vector graphics at the moment.
You should probably have a good look at the manual
to see what C2 is intended to do and what is is not.
