The PDF specification was first published when Adobe® Acrobat® was introduced in 1993. Since then, updated versions of the PDF Reference have been made available from Adobe via the Web. A significant number of developers and systems integrators offer customized enhancements and extensions to Adobe's core family of products. Adobe publishes the PDF specification to foster the creation of an ecosystem around the PDF format. The PDF Reference provides a description of the Portable Document Format and is intended for application developers wishing to develop applications that create PDF files directly, as well as read or modify PDF document content.
This book provides a description of the PDF file format and is intended primarily for developers of PDF producer applications that create PDF files directly. It also contains enough information to allow developers to write PDF consumer applications that read existing PDF files and interpret or modify their contents.
