Can the Dynamic Web TWAIN SDK automatically rotate upside-down pages during the document scanning process?

Dynamic Web TWAIN does not auto-rotate pages by default, but you can rotate images in code using the API covered in this example.

If you have the OCR Add-on (v19.3+), you can call DetectPageOrientation() to detect the page orientation from recognized text and use that result to decide how to rotate.

Some scanners also offer an AutoDeskew/AutoRotate capability that runs on the device. If your scanner supports it, enable that option (see our de-skew guidance for scanner-side setup); otherwise, use the rotation API noted above based on your own detection logic.
