Amazon.com description: Product Description: The official guide to the Portable Document Format! This revised and expanded book from Adobe Systems describes the Portable Document Format (PDF), the native file format of the Adobe(r) Acrobat(r) family of products. These products enable users to exchange and view electronic documents easily and reliably, independently of the environment in which they were created. PDF builds on the PostScript(r) page description language, layering a document structure and interactive navigation features on PostScript's underlying imaging model. Aided by the explosive growth of the Internet, and with well over 100 million copies of the Acrobat Reader application distributed around the world, PDF has become the de facto standard for electronic document exchange. Since the PDF specification was published in 1993, updates have been available from Adobe via the Web. However, this book is the first publication of the specification that is completely self-contained, including the precise documentation of the imaging model from PostScript along with all the PDF-specific features combined in version 1.3 of the PDF standard. This comprehensive specification has been extensively reorganized and revised to ensure that it is complete and accurate. Book Highlights: Explains the overall architecture of PDF and the imaging model it shares with the PostScript language Presents the PDF syntax at the object, file, and document level Includes coverage of graphics operators, fonts, rendering, interactive features, and document exchange Lists all the operators used in describing the visual content of a PDF document This authoritative and up-to-date book is an indispensable resource for application developers building PDF generator applications that create PDF files directly. It is also the best source for information needed to write PDF consumer applications, which read existing PDF files and interpret or modify their contents. The enclosed CD-ROM contains the entire text of this book in PDF.
