Unpaper is also capable of extracting two separate page images where facing pages of a book have been scanned into a single image. Depending on the quality of the original scans, you may find it useful to process them with the unpaper utility, which deletes black borders around the pages and aligns the scanned text squarely on the page.Conversion from PNG format to PBM format with convert:Ĭonvert rig_veda-000.png rig_veda-000.pbm.(The examples below use the convert tool from ImageMagick, but they will also work with GraphicsMagick's gm convert command.) Therefore you need to convert your scans if they are not already in one of these formats. The tool cjb2 is used to creating a DjVu file from a PBM or TIFF file. You will probably also need the ImageMagick or GraphicsMagick software if you need to convert page scans from bitmap formats. You need the DjVuLibre software, a collection of command-line tools for creating, modifying, and viewing DjVu files. By exporting the pages into tiff (same format), it is possible to crop the margins with XnView, and to load the pages into DjVu Solo. Tiff files from Gallica can be opened in FineReader (even after the evaluation period is over). Please see page Help:Converting PDF to DjVu Other formats In this case, one solution is to create a second DjVu file for these pages. This can be problematic when some pages (like in introductions) are numbered in Roman numbers. It is advisable to have the page numbering match that of the original book, for easier use. The DjVu format created a default page numbering which is displayed in a drop-down menu (see Image:Wind in the Willows.djvu). Navigation is done by using the name of the file prefixed by "page:" and followed by "/X", with "X" is the page number. Once a is uploaded to Commons, an index page needs to be created. This is the case on all language versions of Wikisource. Pages of DjVu files can be navigated in Mediawiki installations that have the ProofreadPage extension plugin installed.
