DJVU reader from scratch. C#

I want to write your own djvu reader in C #. Prompt where to start?

Program write in C # (Winforms) in Visual Studio. The problem arises in that I do not understand how to read djvu. Or rather take it apart to import each image for further display in the program.

I have a C# Djvu reader which is open sourced. You can find it here: https://github.com/Telavian/DjvuNet

Edit: My library has been taken over by 4creators at: https://github.com/DjvuNet/DjvuNet

Unfortunately, this project doesn't work fully. Normally the documents having some pages open only. The one-page documents which don't have PageHeader, don't boot. Dear Telavian, look please at this moment. I could send samples of documents which don't open

DjVu is an open standard. There is a C++-based library which reads the format. You can just copy it if you can open source your code (it's GPL): http://djvu.sourceforge.net/.

If not, you can start with the specs at http://djvu.org/resources/ and code up your own from scratch.

Good luck!

CamiNova, the company that took over development and maintenance of DjVu from LizardTech makes a .NET SDK available. I would start there.

You start with File -> New Project

Stack overflow isn't a "do it for you" site.

You've identified the problem. The solution is then to read up on the format and the spec.

Use the FileStream class to read the file.

Use the Bitmap class (WinForms) or the WriteableBitmap class (WPF) to write pixels.
