I have FINALLY got the c++ samples working in Visual Studio 2022. The code I am using is the first tesseract sample code from here <https://tesseract-ocr.github.io/tessdoc/Examples_C++.html> .
Bizarrely, this simple code finds the page numbers at the bottom of the page perfectly happily, whereas the tesseract executable did not. This is good news - though confusing... Thanks to all for your input on this - I think for the moment I'm enough ahead that I can call this issue closed. I will be seeing if I can replicate this in c# which is a more productive environment for me than C++. Iain On Sunday, July 14, 2024 at 7:47:47 AM UTC+1 Iain Downs wrote: > Apologies.
