Overview

PDFBeads – convert scanned images to a single PDF file Version 1.0

Unlike other PDF creation tools, this utility 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 images placed into a background layer.
