Method: HexaPDF::Content::Canvas#polyline

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

#polyline(*points) ⇒ Object

:call-seq:

canvas.polyline(x0, y0, x1, y1, x2, y2, ...)          => canvas

Moves the current point to (x0, y0) and appends line segments between all given consecutive points, i.e. between (x0, y0) and (x1, y1), between (x1, y1) and (x2, y2) and so on. The last point becomes the new current point. Returns self.

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

Examples:

#>pdf
canvas.polyline(50, 50, 150, 50, 150, 150, 50, 150, 50, 50).stroke
