Oh right, for those facing a similar issue, what I did was
1. relpace the eng.traineddata file with the eng.traineddata found here
tesseract-ocr/tessdata:
Trained models with fast variant of the "best" LSTM models + legacy models
(github.com) <https://github.com/tesseract-ocr/tessdata/tree/main> I didn't
delete the original file but renamed it.
2. Test the orientation command directly with tesseract in the terminal
like so tesseract
"C:\Users\osain\OneDrive\Desktop\2000\Document_20240110_0001.jpg" stdout
--psm 0 --oem 0
If this command works in the terminal then it will work in the node wrapper
version. Here is how I called it.
tesseract.recognize(path, {
oem: 0,
psm: 0,
lang: "eng"
})
.then((data) => {
return data
})
.catch((error) => {
console.log(error.message)
})
