If I understood you correctly - You would like to have something like this:
tesseract lm-110.jpg lm-110 -l fra makebox that creates box file and then some tool that will replace symbol(text) part of box file with content of e.g. lm-110.txt (certified text)? I did this with QBE[1]. But there are some (QBE) limitations: - there must be one symbol per box - number of boxes must be the same as count of symbols in your text file (without spaces) So my workflow was something like this: 1. create box file (or open image in QBE - it will offer you to create box file) 2. remove unnecessary boxes (heading, footer, page numbers, scan relics...) 3. split multisymbol boxes (e.g in one box file there was more symbols) 4. import text from external file (QBE->File->Import...->Import text file) It still needs user interaction (no automatic), but it can help, if you need something like that.
