Open Source Ruby PDF Software

Prawn is a pure Ruby PDF generation library that provides a lot of great functionality while trying to remain simple and reasonably performant. Extensive text rendering support, including flowing text and limited inline formatting options. Comprehensive internationalization features, including full support for UTF-8 based fonts, right-to-left text rendering, fallback font support, and extension points for customizable text wrapping. Support for PDF outlines for document navigation. Low level PDF features, allowing users to create custom extensions by dropping down all the way to the PDF object tree layer. (Mostly useful to those with knowledge of the PDF specification). If you are looking for a highly flexible PDF document generation system, Prawn might be the tool for you. It is not a reporting tool or a publishing toolchain, though it could be fairly easily used to build those things.
