DjvuSharp : .NET bindings for DjvuLibre library

DjvuSharp is a fork of v8ify/DjvuSharp. It is a set of .NET bindings for DjvuLibre library and it targets .NET Framework 4.8

It is useful to decode .djvu files and it can render a djvu page to raw pixel data. It also has features to access and decode other djvu file metadata.

Getting Started

This DjvuSharp library fork targets .NET Framework 4.8. DjvuSharp includes a pre-compiled native libraries for:

• Windows x86
• windows x64

Note: The included libraries are built from majkimester/DjVuLibre repo, and they are statically linked with Visual C++ platform libraries. Installing of the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, 2019 and 2022 is not required.

If you have issues with statically linked platform libraries you can build and replace libdjvulibre.dll and libjpeg.dll with dinamically linked platform dlls. In this case the Redistributable needs to be installed, otherwise they will get an error message stating that libdjvulibre.dll could not be loaded because a module was not found.

Usage

Examples

The examples folder in the repository contains some examples of how the library can be used to extract pages from document and render them to a raster to raw pixel bytes.

DjvuSharp library

The first step when using DjvuSharp is to create a DjvuSharp.DjvuDocument object:

    DjvuDocument document = DjvuDocument.Create("path/to/your/djvu/file.djvu");

This object is IDisposable, therefore you should always call the Dispose() method on it once you are done with it (or, better yet, wrap it in a using directive).

From there on, you can work with DjvuDocument object directly. Or you can create a DjvuPage object.

    // Here we are accessing the second page of the document
    // Since, the page numbering starts from 0 in DjvuSharp
    DjvuPage page = new DjvuPage(document, 1);

The DjvuPage is the most important object, as it has most of the useful attributes and methods.
