polygon_round(points, radius, precision, [draw=true], [stroke], [fill], [weight]) -> NULL || List of points

Get a polygon and round his corners

Syntaxe

polygon_round(points=points, radius=20, points=10)

Arguments

Name	Required	Default	Description
`points`	yes	-	List for polygon'coords
`radius`	yes	-	Radius of angles
`precision`	yes	-	Number of points to add (more precision, more points)
`draw`	-	true	If false, return a list of points, and don't draw (stroke, fill & weight are ignored)
`stroke`	-	-	Stroke color
`fill`	-	-	Fill color
`weight`	-	-	Stroke weight (thickness)
