A .Net wrapper for tesseract-ocr

branch: master

A .NET wrapper for tesseract-ocr.


Visual Studio 2012 x86 and x64 Runtimes

Since tesseract and leptonica binaries are compiled with Visual Studio 2012 you'll need to ensure you have the Visual Studio 2012 Runtime installed. This can be found here.

Tesseract language data

You will also need to download the language data files for tesseract 3.02 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 2012 x86 & x64 runtimes installed (see note above).
  3. Download language data files for tesseract 3.02 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.
