# # Composer
#
# This example shows how [HexaPDF::Composer] simplifies the creation of PDF
# documents by providing a high-level interface to the box layouting engine.
#
# Basic style properties can be set on the [HexaPDF::Composer#base_style] style.
# These properties are reused by every box and can be adjusted on a box-by-box
# basis.
#
# Various methods allow the easy creation of boxes, for example, text and image
# boxes. All these boxes are automatically drawn on the page. If the page has
# not enough room left for a box, the box is split across pages (which are
# automatically created) if possible or just drawn on the new page.
#
# Usage:
# : `ruby composer.rb`
#
