README
PDFio - PDF Read/Write Library
==============================
[](https://github.com/michaelrsweet/pdfio/actions/workflows/build.yml)
[](https://scan.coverity.com/projects/michaelrsweet-pdfio)
PDFio is a simple C library for reading and writing PDF files. The primary
goals of PDFio are:
- Read and write any version of PDF file
- Provide access to pages, objects, and streams within a PDF file
- Support reading and writing of encrypted PDF files
- 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.
