Created attachment 183010 [details] A sample document scanned up side down at the scanner side, and then flipped in skanpage and exported with OCR enabled SUMMARY If I scan a document flipped at the scanner side, and then flip the pages in Skanpage before exporting to PDF with OCR enabled, then the OCR seems to produce garbled text. Based on the output, my speculation is that when you do this, the OCR runs on the unflipped pages and are misinterpreted which results in garbled text. I can confirm that by scanning the same document right side up and then exporting with OCR, this issue does not occur. I have attached a sample PDF which I scanned upside down and ran the OCR on to show what I mean. STEPS TO REPRODUCE 1. Scan a document page upside down 2. Flip the page in Skanpage 3. Export the page with OCR enabled 4. Open the page in a PDF reader (Okular is what I used), select some text, copy and paste into a text editor OBSERVED RESULT The text is completely garbled and does not match what the exported PDF displays. EXPECTED RESULT The text should correspond to what the exported PDF displays SOFTWARE/OS VERSIONS Linux/KDE Plasma: Linux Kernel 6.6.90-1-MANJARO (64-bit) KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0 ADDITIONAL INFORMATION I am using Tessaract 5.5.0 and Wayland.
