# ScanSourceSettings-Objekt (IScanSourceSettings-Schnittstelle)

> ScanSourceSettings-Objekt (IScanSourceSettings-Schnittstelle) in der ABBYY FineReader Engine API — Dieses Objekt ermöglicht Zugriff auf die Scan-Einstellungen einer Quelle.

<Note>
  Dieses Objekt ist in FRE für Windows implementiert.
</Note>

Dieses Objekt ermöglicht den Zugriff auf die Scan-Einstellungen einer Quelle.

<Note>
  Standardmäßig ist das Rectangle des Scanbereichs nicht festgelegt (alle Eigenschaften PaperBottom, PaperLeft, PaperRight und PaperTop sind auf 0 gesetzt). In diesem Fall wird der Scanbereich vom Scanner bestimmt, was in der Regel dem gesamten verfügbaren Scanbereich entspricht.
