DJVU reader from scratch. C#

Question

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.

Metro? WinForms? WPF? Silverlight? ASP.Net? MonoTouch? – SLaks Jan 10 '12 at 01:06 — SLaks, Jan 10 '12 at 01:06

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.

I do not ask me. I asked where to I start? What to read, so I can read the file and extract images. – Jin Jan 10 '12 at 01:04

yes, but you asked one of the most vaguest questions ever, with little or no context. What have you tried? what isn't working? what environment? what os? StackOverflow is not Rent-a-Coder. – John Gardner Jan 10 '12 at 01:08

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

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!

Use the FileStream class to read the file.

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

I thought this format the algorithm. And I can not just draw pictures. If I'm wrong correct. – Jin Jan 10 '12 at 01:07
I can't understand what you said. – SLaks Jan 10 '12 at 01:08

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

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
