Abstract:

Encoding electronic documents involves a tradeoff between maximizing the ease of dissemination and preserving the document appearance. For instance, a simple text file is the most easily and universally disseminated form of document, but it preserves none of the appearance. This paper proposes a new image-based document representation, called DigiPaper, which is designed to easily disseminate electronic documents with a guaranteed appearance, thus eliminating the tradeoff. DigiPaper provides fixed appearance by representing documents in image form, but uses new compression techniques to make the file size comparable to formats such as Word, PowerPoint or PDF. DigiPaper compression is based on two technologies, the Mixed Raster Content (MRC) color image model and token-compression. DigiPaper files are much smaller than current image formats used for scanning, achieving about a factor of 7 improvement in compression over TIFF Group 4 compressed images.
