Abstract

This chapter discusses PDF by showing how to use Quartz to create new PDF documents. Creating new PDF documents in Quartz is straightforward, primarily because the PDF file format is the graphics metafile format used by the Quartz imaging model. All drawing performed using Quartz is captured with high fidelity when the content is captured as as a PDF document. PDF is the graphics data format used on the Clipboard, so to support cutting and pasting data between applications. Quartz provides numerous functions that examine PDF content, including PDF metadata and the PDF content stream that includes drawing commands. Moreover, Quartz provides functions that allow you to extract virtually any information you want from a PDF document, including the raw data that makes up the page content stream of any page. In addition, Quartz provides the ability to parse the content stream data. Parsing, examines the drawing content of any page in a PDF document.
