Method: PDF::Core::Text#text_direction

Defined in:

lib/pdf/core/text.rb

#text_direction(direction = nil) ⇒ Object Also known as: text_direction=

Call with no argument to retrieve the current text direction.

Call with a symbol to set the document-wide text direction. This can be overridden using the :direction text option when drawing text or a text box.

pdf.text_direction = :rtl
pdf.text("hello world")                     # prints "dlrow olleh"
pdf.text("hello world", :direction => :ltr) # prints "hello world"

Valid directions are:

• :ltr - left-to-right (default)

• :rtl - right-to-left

Side effects:

• When printing left-to-right, the default text alignment is :left

• When printing right-to-left, the default text alignment is :right
