Preface

The Portable Document Format (PDF) is a file format for representing documents in a manner
independent of the application software, hardware, and operating system used to create them and of the
output device on which they are to be displayed or printed.

What's in this guide?

This document describes Adobe's extension and implementation notes relative to the
soon-to-be-published ISO 32000, Document management, Portable document format, PDF 1.7. Until
ISO 32000 is published, this document will reference the PDF specification represented by the PDF
Reference, sixth edition, version 1.7 (Nov. 2006) and the PDF Redaction: Addendum to the PDF Reference, sixth
edition, version 1.7. The next version of this document to be released after ISO 32000 is published will
reference specifications in ISO 32000.
The extensions are to the PDF document format. Adobe plans to submit these extensions to ISO as
candidates for inclusion into the next version of the ISO 32000 specification. The implementation notes are
differences between the PDF specification, including the extensions, and what is implemented in Adobe
PDF applications, such as Adobe Acrobat.

Who should read this guide?

This guide is intended for developers of applications that consume or produce PDF content. The
implementation notes are intended for developers who need more detail about the Adobe Acrobat family
of products.
