Method: PDF::Writer#move_pointer

Defined in:
lib/pdf/writer.rb

#move_pointer(dy, make_space = false) ⇒ Object

Used to change the vertical position of the writing point. The pointer is moved down the page by dy (that is, #y is reduced by dy), so if the pointer is to be moved up, a negative number must be used. Moving up the page will not move to the previous page because of limitations in the way that PDF::Writer works. The writing point will be limited to the top margin position.

If make_space is true and a new page is forced, then the pointer will be moved down on the new page. This will allow space to be reserved for graphics.
