javascript - paperjs: clip two paths -

-

im trying exclude 1 polygon polygon in paperjs, cant seem figure out how this.

var base_points = [[50,50],[100,50],[125,10]]; var clippolygon = [[50, 50], [100,50], [100,0], [200, 0],[200,300]];  var base = pointstopath(base_points); base.strokecolor = "#000";  var clip =   pointstopath(clippolygon); clip.strokecolor = "#ff00";  var clipped = base.exclude(clip) clipped.fillcolor = '#00ff00'

i made jsfiddle attempting here.
