ger.h - I'm currently in the process (several hours long so far) of getting ANYTHING using tesseract to build in VS2022. I've got to the point where I seem to simply have to add the (many) dlls to the project directory to pass that hurdle. vcpkg inside VS2022 is not at all straightforward, but I finally managed to get the package installed. Tomorrow perhaps for more.
But I'm not sure I see why the simple sample code will work in C++ and not using tesseract,exe directly. I have coded up some samples in c# (using tesseract.net) but they are no better than the exe - so far. I was hoping that I could get to the point where I could get the symbol level confidence and find that the '1' in the file was then found, but that level of the library is poorly documented. I HAVE dealt with large scale C++ open source project and I truly hate it! This is a personal project and I'm not entirely sure I have the will to read that sort of C++. Whilst I was once an expert in C++ that was 20 years ago and I never got on with stl particularly, so it's a bit daunting! Thanks for all input!
