Instance Methods

$obj = $obj->scan

Set up the information for the next page of the document and scan it. The page will be named, placed in its document directory and logged and added to the table of contents file there.

If the page name is the special token 'spine', then the special pageid of "000.spine" is used instead of the current pageid and the document scan format is set for the width of the spine in whichever dimension on the scanbed is appropriate: scanner height if landscape; scanner width if portrait.

Increment the page number or numbers.

Returns self.
