# frozen_string_literal: true

# Horizontal text alignment can be achieved by supplying the <code>:align</code>
# option to the text methods. Available options are <code>:left</code>
# (default), <code>:right</code>, <code>:center</code>, and
# <code>:justify</code>.
#
# Vertical text alignment can be achieved using the <code>:valign</code> option
# with the text methods. Available options are <code>:top</code> (default),
# <code>:center</code>, and <code>:bottom</code>.
#
# Both forms of alignment will be evaluated in the context of the current
# bounding_box.
