Original guide

A list of all the properties for the Document Definition objects in PDF Make. Gathered from the examples source code. Up to date for version 0.1.38.

The Document Definition is a javascript object: {}. It can contain the following.
content: array. This defines the layout of your document. All your tags will be defined in there. You define tags using object (e.g. content: [{text: 'Hello World'}])
styles: object. A dictionary of all the named styles in your document. You can then apply a style to any object using style: 'name' or style: ['name1', 'name2']
defaultStyle: object. Defines a style to be applied to every element in the document.
images: object. Another dictionary that you can use to specify all the images in your document.

View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
View engine: Also called a "template library" or "templater", ie. a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).
HTML templater: A template library that's designed specifically for generating HTML. It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.
String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potenti
