#polygon(*points) ⇒ Object
Draws a polygon. The arguments are [x
, y
] pairs that define the points that make up the polygon. At least two points must be specified. If the last point is not the same as the first, adds an additional point to close the polygon.

#polyline(*points) ⇒ Object
Draws a polyline. The arguments are [x
, y
] pairs that define the points that make up the polyline. At least two points must be specified.

#rect(width, height, x = 0, y = 0) ⇒ Object
Draws a rectangle whose upper-left corner is [x
, y
] and with the specified width
and height
. Unless otherwise specified the rectangle has square corners. Returns a Rectangle object.
Draw a rectangle with rounded corners by calling the #round method on the Rectangle object. rx
and ry
are the corner radii in the x- and y-directions. For example:
canvas.rect(width, height, x, y).round(8, 6)
If ry
is omitted it defaults to rx
.
