You will probably also need the Imagemagick software for converting scans from one format to another: You need the djvu software, which includes a viewer, and some tools for creating and handling DJVU files. Method 1 - page at a time with DjVuLibre You may consider preprocessing the scans with Scan Tailor. Linux See also: User:GrafZahl/How to digitalise works for Wikisource Method 0 - converting graphic files with foreground/background separation To use it, you will need Python, Imagemagick and DjvuLibre. Currently this script is for Windows, but it can be easily converted for Linux. This script allows you to take a whole directory of image files (JPG, PNG, GIF, TIFF, and any file that Imagemagick can convert to PPM) and convert and collate them automatically into a DJVU file. The size can be substantially reduced by applying foreground/background separation with didjvu and/or minidjvu. Individual DjVu pages can be aggregated into a multi-page DjVu using the djvm program this program can also be used to insert or delete pages from a djvu file.Īn important caveat of this process is that high quality scans come at the cost of larger files, and there is currently a 100 Mb limit on uploads to commons. All of these image format conversions can be performed by the freeware ImageMagick library (in batch, with mogrify). black-and-white) scans, such as most page text images, a smaller DjVu file can be obtained by converting the page images to the monochrome PBM format, then encoding to DjVu using the cjb2 encoder. Images in lossless formats such as PNG should be converted to PPM (for colour scans) or PGM (for greyscale scans), then encoded using c44. Jpeg images can be directly encoded into individual DjVu pages using the c44 encoder. However, a far higher quality document can be achieved using the DjVuLibre software library.

One could convert using PostScript or multipage TIFF as the intermediate format, rather than PDF, but this would of course require different conversion tools. Note that there are many other options for converting pages to. If the scanned images are made available as individual images, then the easiest option is to print them to a PDF document via one of the many "virtual printer" tools, such as the free PDFCreator then convert the PDF document to DjVu as described above.
