That text layer can be generated when "printing" to DjVu, but it normally is built from the image material that you get when you scan files to the DjVu format. When available it uses the C++ based djvu2txt from the djvu-libre toolset, otherwise it uses a, much slower, decoding done in Python. When the DjVu support for Calibre was added a few years ago, it was implemented by taking the text layer, when available, and extract and convert that to textual material usable for conversion, by Calibre, to other formats. Help me to view books correctly.Įdit (day 06/ month 05/year 2016): I filed a bug report and got a response from the developer. I don't understand if Calibre is having a bug or if it's converting ebooks to some basic format. Other viewer (not calibre) can format equations, of the same ebook, and displays the whole book correctly, this is how it should look: If I open them from Windows, and I choose to "open with" Calibre the ebook viewer, the result is that they are displayed very badly, with a ugly standard font, with equations all ugly, It easier to show it so I will copy some images comparing how it's viewed with Calibre vs other viewers that work fine.Ĭalibre with a DjVu, all the pages looks like this: If I try to choose them with Calibre open from my library, then they never finish loading. My problem is when viewing ebooks with Calibre viewer, two things happen:
CALIBRE E BOOK VIEWER E LOOKS LIKE C UPDATE
There was a update very recently which I installed, so this could be due to bad installation or something like that. I don't know what version the program is, since I couldn't find any about dialog to confirm it. I'm using Calibre the ebook viewer to view PDFs, DjVu, and ePub books.
