Method: HexaPDF::Content::Canvas#close_subpath

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

#close_subpath ⇒ Object

:call-seq:

canvas.close_subpath      => canvas

Closes the current subpath by appending a straight line from the current point to the start point of the subpath which also becomes the new current point. Returns self.

If there is no current path when the method is invoked, an error is raised since a valid current point (#current_point) is needed.

Examples:

#>pdf
canvas.move_to(10, 10).
  line_to(110, 10).
  line_to(60, 60).
  close_subpath.           # Draws the line from (60, 60) to (10, 10)
  stroke
