How to rotate the preview
You can rotate the document preview from the document view. Open the document and click the rotate icon in the preview on the right-hand side.
What rotation does not change
The rotation is temporary. When you close the document and open it again, the preview is shown in its original orientation and you need to rotate it again.
Rotation is available for PDF files only.
Rotating the preview only changes what you see on screen. It does not change the captured data.
