I’ve tried importing some scanned Korean text and then running OCR with mixed results.
The first page worked well, it straightened the text and I could copy and paste the Korean text fine, but for other pages, the image of the Korean text was flipped vertically in the final PDF+Text document, and of course the OCR text was gibberish.
Are there any preparation steps I can take with the images so that they get OCR’ed more reliably?
