The ABC of PDF with iText
The ABC of PDF with iText
PDF Syntax essentials
About the Book
This book is a vademecum for my other books entitled "Create your PDFs with iText," "Update your PDFs with iText," and "Sign your PDFs with iText."
In the past, we used to refer to ISO-32000 whenever somebody asked "why can't I use PDF as a format for editing documents" or whenever somebody wanted to use a feature that wasn't supported out-of-the-box.
Although it wasn't always our intention, answering "read the specs" was lethal for the conversation as the spec consists of more than a thousand pages. In this short book, I'd like to give a short introduction to the syntax of the Portable Document Format. It's not the definitive guide, but it should be sufficient to help you out when reading the other iText books.
