libHaru is a free, cross platform, open source library for generating PDF files.
At this moment libHaru does not support reading and editing existing PDF files and it's unlikely this support will ever appear.
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.
Looking for a new maintainer!
The project seems to be in more or less good shape (as in `it still compiles and works`), but it hasn't been actively maintained
and/or developed for a few years and badly needs a new maintainer.
If you think you can do it and have some spare time to spend on it (not too much), don't hesitate to introduce yourself on the mailing list:
email@example.com (you might want to subscribe to it first).
