I am using a djvu file, and with okular I have annotations in it. Now, I wish to be able to use this file in Mendeley, which supports only pdf extensions. I know that I can save annotations in okular using Export As -> Document Archive. But that is saved with .okular extension. How do I convert it to .pdf?
DjVu is a computer file format used for storing eBooks and scanned documents. The DjVu file format uses the extension .djvu or .djv and is developed as an alternative to PDF. It uses technologies such as arithmetic coding and lossy compression for achieving the fast and small loading of high-quality and readable images.
To open a DjVu file on Mac, you need to download a DjVu viewer Mac OS X. DjVu viewer Mac OS X is a .djvu file reader enabling you to open and view DjVu files on Mac and convert DjVu to PDF mac. Although there are many types of DjVu viewer Mac OS X on the market, the basic functionality is almost the same. The following introduces how to open DjVu file on Mac using DjView4.
Opening a .djvu file can be a bit challenging for some users as the format is not as widely supported as other formats like PDF. However, there are several options available for opening .djvu files, including the following:
Although there are several options available for opening .djvu files, the process can still be uneasy for some users, especially those who are not familiar with the .djvu format. However, using an online conversion tool like Visual Paradigm Online can make the process much easier and more convenient by converting the file to PDF format.
Printing a .djvu file can be a bit more challenging than printing other file formats, as not all printers support this format natively. However, there are several options available for printing .djvu files, including the following:
DjVu is a good format to distribute documents and books. DjVu need no fonts, support text layer and outline. With Djvu-Spec Pdf2Djvu Converter you can easy convert pdf to djvu.Portable version - link "Files"
Note that there are many other options for converting pages to .djvu. One could convert using PostScript or multipage TIFF as the intermediate format, rather than PDF, but this would of course require different conversion tools. It is also possible to convert from .pdf or .ps to .djvu with the DjVuLibre software and its GSDjVu plug-in but due to licensing restrictions installing the plug-in is a fairly intricate process that involves compiling a patched version of Ghostscript.
Another free Windows tool that can come in handy for the images-to-pdf-to-djvu process is ConcatPDF, a GUI tool that permits easy splitting and merging of PDF files. This tool can also be used online. An example of how ConcatPDF might be used is: if a 100-page document has previously been scanned and converted to .djvu and the single page #42 needs to be re-scanned, ConcatPDF would allow that one page to be inserted into the intermediate .pdf file without tracking down the other page images and re-composing the entire document. Installing ConcatPDF version 1.1 requires as prerequisites that the free Microsoft program libraries Microsoft .NET Framework Version 1 and the corresponding Visual J# .NET Redistributable Package be installed beforehand.
However, a far higher quality document can be achieved using the DjVuLibre software library. Jpeg images can be directly encoded into individual DjVu pages using the c44 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. For bitonal (i.e. 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. All of these image format conversions can be performed by the freeware ImageMagick library (in batch, with mogrify). 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.
An 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. The size can be substantially reduced by applying foreground/background separation with didjvu and/or minidjvu.
You need the djvu software, which includes a viewer, and some tools for creating and handling DJVU files. You will probably also need the Imagemagick software for converting scans from one format to another:
With pdf2djvu, you need to crop directly the pdf before the conversion. On Linux this may be quite difficult. You could use ImageMagick convert -crop, but attention: with multiple page big PDF document, this can take several GB of memory (the limit is 16 TB!) and kill your computer if you don't use the -limit area 1 option directly after -crop. This make the conversion very long.
Use djvudigital,[5] which like pdf2djvu converts pdf directly in DjVu.[6] There are licensing problems, because the GSDjVu library has a different license, then you'll need to compile it by yourself; the included utils make this step quite easy, but still long (about 1 hour) and a bit annoying.[7]
But, then you can convert PDF document into DjVu with a single command (see the previous section for crop). The conversion is slow (I find it will complete a 300 page PDF document in about 30-40 minutes). The resulting DjVu is of higher quality and lower file size compared to both the previous two methods.[1] Additionally, DjVuDigital can handle JPEG2000 (aka JPX) files embedded in PDF documents, which is a feature of many Google books. pdf2djvu, Any2Djvu and Internet Archive conversions all fail to convert these files, leaving blank pages in the output.
Another method to convert the images to djvu is to zip them and use the Any2Djvu site to create the djvu file. The Any2Djvu will extract the images in the zip and create a OCRed djvu. OCR functions will only with English text.
The OCR option available at the free conversion service Any2DjVu does do an OCR of the scanned image but the resulting text is embedded within the .djvu file itself and must be extracted so it can be used on Wikisource.
Many of the already-created djvu files available at archive.org and other sites have the Google copyright page attached to the front of the document. Wikimedia policy, based on an analysis of the underlying law, does not accept that copyright is established on a public domain work simply by scanning or copying it or taking a two-dimensional photograph that faithfully represents its subject. See Wikimedia Commons for more information about scans, artwork and the position of the WMF.
Such copyright pages and other extraneous material can be removed with DjVuLibre, an open source program maintained by the inventors of djvu under the GNU Public License. Binaries are available for Windows, Mac, Linux, Solaris, and IRIX. It includes djvm.exe, which is run as a command-line utility. If you cannot figure out how to do this, you can message Mkoyle (talk), and he will do it for your file and email the file to you for upload. The command line to delete (-d) the first page (1) is as follows:
If a DJVU file is missing pages, you can insert placeholders, so that if the pages are found and inserted later, existing pages won't need to be moved. You can use File:Generic placeholder page.djvu for the placeholder.
The [[File:...]] link tag accepts a named parameter "page" so that, for example, this wiki code displays the image of page 164 of the file Emily Dickinson Poems (1890).djvu on the right, 150 pixels wide (the rear cover of the book, containing no text):
Lengthy comments below discuss representing smaller images from DjVu document page as separate objects, which is not easily possible because DjVu document page is itself just a single image with optional text layer, with no "information" about smaller images as separate objects. If DjVu document has color images, then they'll be usually placed on background layer; in this case user can take advantage of tools like ddjvu (extract only background layer) and imagemagick (auto-crop) to output just images instead whole canvas, but it can't be automated for creating PDF output 041b061a72
