Users sometimes have to deal with new and yet completely unknown formats. In many cases, such acquaintance is accompanied by increased nervousness, because it is very important to quickly perform certain manipulations, and the proposed file is stubbornly unwilling to open on a computer.
Similarly, the situation with the DjVu format. When trying to open scanned books and magazines downloaded from the Internet, a window appears on the PC screen, announcing that the computer does not have DjVu reading software installed.
Of course, if you can refuse to open a file with the DjVu extension, download the necessary literature in a different format, then do just that. However, in many cases, you simply cannot back up, so you have to figure out what the DjVu format is, rather than open it on your computer.
Assigning DjVu format
Such a strange format for many is not new and incomprehensible for experienced users, since it has already managed to take root systematically over the long fifteen years of its existence.
Mostly in this format are stored scanned images. Its advantage is that it is accompanied by much smaller sizes than other formats of scanned tables, images, charts and other information.
Advantages of DjVu
If you identify a task that involves the digitization of important literature, you can solve it quickly enough if you have a computer and a scanner at hand.
However, it is important to consider the format in which you will save the scanned material. You can save it, like the rest of the image, but the size of even one page will be extremely large, not to mention the whole book. In addition, you will not be able to search for a given word or fragment, which is often needed by users who do not just read the literature, but write a report or scientific work.
There is also a second option to save scanned materials, which implies a powerful compression during saving. In this case, it is possible to make the size of the digitized book minimal, also to provide conditions for a reliable and fast search, but you will have to accept the loss of images, charts and drawings.
If you do not want to drive yourself into the framework, then you have to look for a successful alternative, which is the format of DjVu.
The main advantages of "deja vu" are:
- powerful compression, exceeding at least ten times the compression of jpeg (one sheet is accompanied by a size of 10 to 50 KB);
- preservation of clarity for textual and graphical information;
- implementation of a full search.
Thanks to such excellent characteristics, the DjVu format has successfully “got accustomed” and is currently popular with many users.
For those who are not yet familiar with it, it is easier to learn new knowledge about how to open DjVu on a computer.
Software to open djvu files
So, if you are faced with the need to open a document saved in the DjVu format, it will be useful for you to familiarize yourself with some programs that are oriented to work with documents with such an extension. Install absolutely all software on a computer is not necessary. It is important to choose one program for yourself, install it on a PC and start enjoying its work, no longer asking how to open the DjVu file.
