Overview

Linearization (PDF 1.2+ fast-web-view, ISO 32000-2 §7.6.2 + Annex F).

A linearized PDF is structured so the first page's data appears near the front of the file, enabling incremental download and display. The structure has:

Part 1: Linearization parameter dict + first-page xref
Part 2: First page's document objects
Part 3: Remaining pages' objects
Part 4: Hint stream (page-offset + shared-object tables)
Part 5: Main xref + trailer
