A .NET wrapper for tesseract-ocr.

Version 3.0 Note

The current version of 3.0 unfortunately has some stability issues (See issue #231) please use the previously released version (2.4.1) which can be installed using the following command from the Package Manager Console (View -> Other Windows -> Package Manager Console):

Install-Package Tesseract -Version 2.4.1.0

Dependencies

Visual Studio 2013 x86 and x64 Runtimes

Since tesseract and leptonica binaries are compiled with Visual Studio 2013 you'll need to ensure you have the Visual Studio 2013 Runtime installed.

Tesseract language data

You will also need to download the language data files for tesseract 3.04 from tesseract-ocr.

Getting started quickly

1. Add the Tesseract NuGet Package by running Install-Package Tesseract from the Package Manager Console.
2. Ensure you have Visual Studio 2013 x86 & x64 runtimes installed (see note above).
3. Download language data files for tesseract 3.04 from tesseract-ocr and add them to your project, ensure 'Copy to output directory' is set to Always.
4. Check out the Samples solution ~/Samples/Tesseract.Samples.sln for a working example

If you run into any issues please check out this wiki page which details a number common issues and some potential solutions.
