Introduction

PDFio is a simple C library for reading and writing PDF files. The primary goals of pdfio are:

• Read any PDF file with or without encryption or linearization
• Write PDF files without encryption or linearization
• Extract or embed useful metadata (author, creator, page information, etc.)
• "Filter" PDF files, for example to extract a range of pages or to embed fonts that are missing from a PDF
• Provide access to objects used for each page

PDFio is not concerned with rendering or viewing a PDF file, although a PDF RIP or viewer could be written using it.
