*Hello Nick, * thank you very much for your answer. I'm coming from the user space, my technical background is limited. This is why my understanding is always only half of the game, but at least getting some directions.
So I found this: http://www.openocr.net/ - I've worked with docker, so I understand a bit the architecture, and I like that it hides away the more diffcult stuff and it is nicely boxed :) If you scroll down, there is a features list. The 4th item says: - Pass arguments to Tesseract such as character whitelist and page segment mode Is this what we are looking for? "page segment mode" and "character whitelist"? If I puzzle that together correctly, this is the api access you talked about... But I don't feel confident enough to make a conclusion. I would prefer to abstract the things, I don't understand. This is fair, isn't it? :) Thanks and I hope this might inspire anyone, who happens to read this anyhow... Am Dienstag, 29.
