DjvuSharp is a set of .NET bindings for DjvuLibre library and targets .NET standard 2.0
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.
The DjvuSharp library targets .NET Standard 2.0, thus it can be used in projects that target .NET Standard 2.0+, .NET Core 2.0+, .NET 5.0+ and possibly others. DjvuSharp includes a pre-compiled native library, which currently supports the following platforms:
- win-64
- linux-64
Support for other platforms is planned.
Note: you should make sure that end users on Windows install the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, 2019 and 2022 for their platform, otherwise they will get an error message stating that djvulibre-21.dll could not be loaded because a module was not found.
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.
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.
