This product features three tools for scanned image "cleanup" in PDF.
Eraser removes dirty edges, punch holes etc
Positioner allows the image to be correctly positioned on the screen (thus correcting the irritating problem when dealing with scanned documents where all the pages are not correctly "centred")
Measurer is a measurement tool allowing the precise measurement of two points on a PDF page
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
