    PDFBeads is a small utility written in Ruby which takes scanned
    page images and converts them into a single PDF file. Unlike other
    PDF creation tools, PDFBeads attempts to implement the approach
    typically used for DjVu books. Its key feature is separating scanned
    text (typically black, but indexed images with a small number of
    colors are also accepted) from halftone pictures. Each type of
    graphical data is encoded into its own layer with a specific
    compression method and resolution.
