PDF Document Creation, Viewing, and Transforming

PDF documents store resolution-independent vector graphics, text, and images as a series of commands written in a compact programming language. A PDF document can contain multiple pages of images and text. PDF is useful for creating cross-platform, read-only documents and for drawing resolution-independent graphics.

Quartz creates, for all applications, high-fidelity PDF documents that preserve the drawing operations of the application, as shown in Figure 13-1. The resulting PDF may be optimized for a specific use (such as a particular printer, or for the web) by other parts of the system, or by third-party products. PDF documents generated by Quartz view correctly in Preview and Acrobat.

Quartz not only uses PDF as its “digital paper” but also includes as part of its API a number of functions that you can use to display and generate PDF files and to accomplish a number of other PDF-related tasks. The following tasks are discussed in this chapter:

• “Opening and Viewing a PDF”

• “Creating a Transform for a PDF Page”

• “Creating a PDF File”

• “Adding Links”

• “Protecting PDF Content”

For detailed information about PDF, including the PDF language and syntax, see PDF Reference, Fourth Edition, Version 1.5.
