Masked areas can be defined to hide information on a document from an operator. When the document is displayed, the Document Viewer displays the defined areas masked in either black or white, which means that they are not visible to the operator.

Documents that display masked areas have some restrictions:

• The document cannot be rotated. A warning is displayed if you try to rotate the page.

• You cannot assign another classification result.

• You cannot use Edit Batch mode.

• Lassoing the masked area in the viewer does not return OCR results.

• You cannot debug scripts.
