Module: Vivlio::PDF::Outline

Defined in:
lib/vivlio/pdf/outline.rb

Overview

How PDF bookmarks are produced. Each strategy answers two questions: whether Chromium should build the outline itself while printing, and which TOC entries (if any) we write afterwards with HexaPDF.

Defined Under Namespace

Classes: Headings, None, Strategy, Toc
