1. You can use tesseract.exe from here:
https://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-w64-setup-5.3.3.20231005.exe
Properly working:
tesseract.exe invoice.png texto.txt
oText:Add(OCRFromFileUsingTransym( TestTifFile, 4 ) )
I tried emailing the .dll to Enrico but nowadays you can't send a .dll even you alter the extension.
