Method: HexaPDF::Content::Canvas#polygon

Defined in:
lib/hexapdf/content/canvas.rb

#polygon(*points, radius: 0) ⇒ Object

:call-seq:

canvas.polygon(x0, y0, x1, y1, x2, y2, ..., radius: 0)          => canvas

Appends a polygon consisting of the given points to the path as a complete subpath and returns self. The point (x0, y0 + radius) becomes the new current point.

If radius is greater than 0, the corners are rounded with the given radius.

If there is no current path when the method is invoked, a new path is automatically begun.

Examples:

#>pdf
canvas.polygon(10, 10, 90, 10, 70, 90, 20, 100).stroke
canvas.stroke_color("hp-blue").
  polygon(130, 130, 150, 100, 170, 150, 130, 190, radius: 10).stroke
