libHaru is a free, cross platform, open source library for generating PDF files.

It supports the following features:

  • Generating PDF files with lines, text, images.
  • Outline, text annotation, link annotation.
  • Compressing document with deflate-decode.
  • Embedding PNG, Jpeg images.
  • Embedding Type1 font and TrueType font.
  • Creating encrypted PDF files.
  • Using various character sets (ISO8859-1~16, MSCP1250~8, KOI8-R).
  • Supporting CJK fonts and encodings.

You can add the feature of PDF creation by using HARU without understanding complicated internal structure of PDF.

libHaru is written in ANSI C, so theoretically it supports most of the modern OSes.
