Module render 

Low-level PDF rendering utilities.

This module provides low-level abstractions over printpdf: A Renderer creates a document with one or more pages with different sizes. A Page has one or more layers, all of the same size. A Layer can be used to access its Area.

An Area is a view on a full layer or on a part of a layer. It can be used to print lines and text. For more advanced text formatting, you can create a TextSection from an Area.
