How can I rotate my signature in Preview? I have scanned my signature and can insert it just fine, but at the wrong angle!

How can I rotate it (90 deg)?
I've been having the same problem, but I solved it by opening the pdf file in Preview, hitting File &gt; Duplicate, then adding the signature in the newly created file. This corrects the orientation of the file so that Preview can identify lines and you can just click on them with the signature tool (from the Annotate/Edit toolbar) and add your signature.
