Prawn

Prawn is a Ruby library and document layout tool used for the programmatic generation of PDF files. It functions as a vector graphics engine that allows for the creation of portable documents containing formatted text, custom shapes, and organized page layouts.

The library differentiates itself through a coordinate-based vector rendering system that supports multi-stop gradient fills, complex polygons, and layer-based blending. It provides a comprehensive typography system capable of embedding TrueType and OpenType fonts to support UTF-8 characters and right-to-left text for multilingual publishing.

Broad capabilities include document structure management with hierarchical outlines, the embedding of raster images with transparency support, and the insertion of interactive hyperlinks. The system also includes security features for document encryption and password protection.
