PDF Reference version 1.4 is a thorough, updated reference for software developers looking to incorporate PDF capabilities into their applications. These could be PDF producer apps (those that "save to" PDF directly) or PDF consumer apps (those that read PDFs and allow users to modify their contents). The book includes all the material covered in the previous edition on version 1.3, as well as items new to 1.4. The new features include a filter for decoding JBIG2-encoded data, enhancements to encryption and interactive forms, ability to import content from one PDF to another, addition viewer preferences and trigger events, and accessibility support for disabled users.
The book includes a general description of PDF architecture and a comparison to the PostScript language, and explanations of the following: PDF syntax at the object, file and document level, graphics operators, facilities for presenting text in the form of character shapes or "glyphs" defined by the font, how device-independent descriptions render the page to match the output device, version 1.4's transparent imaging model (which allows objects to be painted with varying degrees of opacity), interactive features, and how PDFs can incorporate higher-level information useful for the interchange of documents among apps. A PDF version of the entire book is included on the companion CD. Also, the index is lengthy and detailed--a definite plus to any reference.
The book is surprisingly readable despite its highly technical content. However, it's unlikely that general graphics professionals who only create and print PDFs will need this reference. It tells how PDFs work (right down to the syntax, operators and Postscript), not how to work with PDFs. Developers, on the other hand, who are creating applications that will read and/or generate PDFs, will find this an essential addition to their bookshelves. --Angelynn Grant
