Video instruction: how to open djvu format

Hello, dear readers of the blog site. You've probably come across scanned images on the Internet. books in Djvu format(their files have the same extension).

Usually, it is not fiction that is distributed online in this way, but books containing drawings, graphs, formulas and other things that are quite difficult to convert into digital format using text recognition programs.

At first, I thought that this strange djvu() format was an ordinary set of raster images (photos) that were the result of scanning a book. But in this case the file size would be very large, and we do not observe this.

What is a file with such a mysterious extension and how can you open it to start reading the information contained in “déjà vu”, and what programs are best to use. I will try to answer all these questions in this article.

What is a Djvu file?

It turns out that djvu was developed about fifteen years ago and is a very successful mixture of test and graphic formats. In principle, when digitizing books, two scenarios are possible:

Perform text recognition on a scanned page and save it using compression algorithms, which allows you to obtain a very small weight of the final file. The downside is that you lose images, backgrounds, marginal notes, dog-ears, and other things that may be important in some cases. But it will be possible to conduct a full search using recognized texts.
You can save scanned texts as pictures, for which these or tiff are suitable. However, the weight of even one scanned page will be prohibitively high if we want to maintain quality. Well, it will be impossible to search through texts.

Djvu combines the advantages of the methods described above, while having virtually no disadvantages. Format Deja vu can be classified as text-graphic, which in itself already sounds unusual, but it promises a lot of dividends. Judge for yourself:

The original scanned image is compressed in Djvu ten times more densely than it would be using JPEG, and its quality remains virtually unchanged. At the same time, jpeg will definitely blur the text, graphics, and everything that is possible, and our hero will leave everything in its original form.
An A4 sheet, scanned and converted to déjà vu, will weigh around 50 kilobytes (read about that) if the source had color graphics (or background), and around 10 kilobytes if it was black and white. Brilliant, and this is taking into account the fact that the scanning was carried out in a high resolution of 300 DPI. The same file saved in tiff format (without loss of quality) would weigh several hundred times more.
The Djvu file contains a text layer through which you can conduct a full search, and if you wish, you can leave only it (removing the color mask and background information), which will further reduce the size.

All this is achieved thanks to a rather original approach. I could be wrong, but in my opinion it is as follows:

Separate the text of the page and its background. The algorithm monitors many factors and, with the right settings, can even rip out the text component from the cover of a magazine, where words can also be used as a background.
The text is saved in a one-bit version (black and white) and is compressed quite tightly.
The background is saved separately and compressed a little less efficiently.
Information about the color of the text and illustrations used in the book is also compressed, but using a different algorithm.
As I already mentioned, the Djvu format provides a separate text field, thanks to which you can search through scanned books.

But the questions of creation and principles of data formation in déjà vu files are of interest to us insofar as, and it will be much more interesting to find out how they can be open and read Djvu.

Naturally, special reading programs (readers) are used for this purpose, which are available for both computers and mobile devices based on Android or iOS (ipad, iPhone). It’s convenient, after all, on the way home or to work to increase your level of education by reading a smart book on your mobile phone.

How to open Djvu - reading programs on a computer

There are several programs that are focused on working only with déjà vu files, but there are a number of universal solutions that allow you to read books in almost any form. There are also Djvu editors that allow you to edit or even create your own masterpieces.

Among Deja Vu readers intended for computers, it is worth highlighting the following readers:

It fully supports the Russian language and even managed to be captured by the “great and terrible” Yandex, forcing you almost by force and by default searching in all your browsers:

In general, they make it possible to abandon all this wealth (including), but not everyone pays attention to this when installing the program. Of course, with the same one it all looks even more intrusive, but the leading Runet search engine has also already filled all the free programs with its add-ons to the point of “don’t play around.”

As I already mentioned, Djvu can have a text layer embedded, so when reading books containing it, you can search by words and phrases.

On the left, WinDjView has a navigator with page thumbnails, and at the top there is a toolbar where you can open a new file, change the scale and type of display of pages (endless feed or imitation of a book spread), and also rotate them, if necessary, at an angle multiple of 90 degrees.

What’s noteworthy is that this deja vu reader opens new books in new tabs, which allows you to work with several materials at once in one program window. There is also the ability to make bookmarks and leave comments (from the right-click context menu). You can use a screen magnifier from the toolbar and full-screen viewing mode (in this case, you can turn pages with a simple mouse click).

If you select “File” - “Settings” from the WinDjView program menu, then on the second tab you can set the inversion of colors (for example, in order to read white text on a black background), as well as adjust the brightness, contrast or gamma for better perception of the document in Djvu format.

At the beginning of the article, I mentioned that in déjà vu, the scanned document is broken down into a black and white text component, a background, and foreground color information. So, in WinDjView all this can be clearly seen by selecting “view” - “mode” from the menu.

The latest current version dates back to 2005 (version 2.0.0.26) and its compatibility with modern operating systems is not guaranteed, although it still works on my Windows Vista, although not as quickly as its modern counterpart described just above. It does not require installation and works directly from the folder where you unpacked the archive with the program.

During installation, you need to check the box that you will not use this reader for commercial purposes, so as not to pay for the program.

Well, STDU Viewer will also ask you which file extensions you would like to associate it with, except for deja vu.

In principle, there is nothing so global in this reader that would not be in WinDjView, but... Firstly, it’s captivating a huge number of formats, which can be opened and read using this program.

Secondly, a very convenient and thoughtful interface.

Almost all of the reader’s functionality is displayed in the form of toolbars located around the entire perimeter of the program window. The place where thumbnails of the pages of the book you are reading are usually displayed, has as many as six tabs located at the bottom.

Not all of them apply to Djvu, but still. The same bookmarks, which can be designed in the form of a tree, can easily replace the missing navigation in your reference book or reference book.

The brightness and contrast settings are also displayed as an icon in the lower right corner, where there are also buttons for switching the document display mode.

Thirdly, there are some nice functional delights that will help during daily work with STDU Viewer:

Well, fourthly, there is a huge number of settings that can be made in STDU Viewer so that this reader is fully suited to your habits and needs.

For example, you can customize (File - Program Settings) even the appearance of the tabs, which, of course, is a trifle, but quite pleasant:

Djvu readers for Android and iOS (iPad and iPhone)

For some reason, I mostly manage to read books on the road, but there are always a lot of other, more important and interesting things to do. In this regard, I was faced with the task of downloading some suitable déjà vu reader for my beloved iPad, received as a gift from Profit Partner, but also in addition to everything - for an Android phone.

At the same time, I try to try all the free options for programs and applications before coming to the conclusion that I have no other option but to part with my hard-earned money. Actually, the main candidates for the place of Djvu are e-readers for iOS on the Internet. DjVU Book Reader.

Everything seems to be fine, both reviews and screenshots, but they are asking for it, albeit a small, but still a sum of money (169 rubles). I thought that this software was a bit of a mess, so I entered the word Djvu in the search bar in the Apple Store and asked to filter only free applications.

After testing to open various files in déjà vu format and assessing ease of use and functionality, a clear leader emerged among free programs for iPad - KyBook.

The software is unique, in my opinion, because while it is free, it fully supports EPUB, FB2, PDF, DJVU, CBR, CBZ and audiobooks in MP3, M4A, M4B formats.

When reading, the pages turn beautifully (the animation can be customized), there are a lot of settings and functionality, such as creating bookmarks, leaving notes, searching through the contents of the book, etc. things that are accessible from the top toolbar.

The KyBook reader has unexpectedly many settings:

Including there is a separate group of settings for this reader for PDF and DJVU formats:

In the library of this reader, you can sort books, create shelves for them, move files between them, rename them, and do everything that is usually required from such programs.

In addition, it is possible to use your existing applications for working with cloud storage systems such as , or Google Drive.

True, by providing access to your files in Dropbox and other clouds, KyBook warns you that it can even change them, which I personally don’t really like.

So I Djvu files are thrown into the Dropbox folder on the computer (via Wi-Fi), after which I open the application of the same name on the iPad and add them to my favorites, so that they are not later pulled over the mobile Internet, which is not always fast and also limited.

It seems to me that it will be safer this way.

Now it’s time to move on to the question of how to open Djvu on Android. The Internet told me that the best options are two free applications, which I still use today, because I didn’t have any particular complaints about their work, but just in case I left both of them in case some kind of twisted deja vu file opens one of them can not.

So, I present to you deja vu readers for Android:

Good luck to you! See you soon on the pages of the blog site
