CaptureOnTouch V5 Pro - Auto rotation issue with PDFs

evrena — Sat, 30 Aug 2025 07:45:45 GMT

I am using CaptureOnTouch V5 Pro with a DR-C230 scanner on a Windows 11 pc. Only when saving as PDF, the software automatically rotates the document to match the orientation of the scanned text, by adding margins from all sides and altering the dimensions of the created document. The tick box "rotate image to match orientation of the text" or the PDF output settings including "Add OCR information" don't make any difference. This doesn't happen when saving as PNG. Any help would be appreciated.

Hello!

The issue of your document automatically rotating and gaining margins when saved as a PDF is caused by how CaptureOnTouch V5 Pro's OCR engine and PDF conversion work together. Because a PDF is a fixed-size format, the software adds margins when it rotates the image to correct the text orientation. To fix this, you should try disabling any auto-rotate or deskew settings in the scanner's underlying TWAIN driver settings, or configure the software to save as an "Image-only PDF" to bypass the OCR process entirely.

Thanks for the hint. I found that the "Processing Mode" option in the PDF settings was causing the documents to auto-rotate. I fixed the issue by choosing "Speed Priority".
