# ScanSourceSettings Object (IScanSourceSettings Interface)

<Note>
  This object is implemented in FRE for Windows.
</Note>

This object provides access to the scanning settings of a source.

<Note>
  By default, the scanning area rectangle is not set (all the properties PaperBottom , PaperLeft , PaperRight , PaperTop are set to 0). In this case, the scanning area will be selected by the scanner, which will generally mean the whole available scanning area.
