CamlPDF

This is CamlPDF, an OCaml library for reading, writing and manipulating Adobe portable document files.

CamlPDF consists of a set of low level modules for representing, reading and writing the basic structure of PDF, together with an initial attempt at a higher level API.

CamlPDF is released under a BSD licence with special exceptions. See the LICENCE file in the source for details.

CamlPDF forms the basis of our PDF Command-line Toolkit and .NET PDF Toolkit, our PDF Editor for Mac OS X and the PDF import for a major commercial vector graphics package.

Features

• Support for PDF versions 1.0-1.7;
• Large file support: 64-bit file handles and fully tail-recursive;
• Lazy data reading, lexing and parsing - Optionally reads and processes data only when it's required;
• Depends only on zlib.
• Cross compiles with Microsoft F# to build a .NET DLL

Notable Omissions

• External streams.
