The PDF output format in OmniPage uses predefined MarkedContent
object types defined in PDF 1.4.
Human reading object
is the original object type in OmniPage.
Tagged object is a MarkedContent
object type used in a PDF StructTree,
the Attributes column shows the
standard attributes of the Tagged object.
If an attribute is not filled in a PDF file, the value of the attribute
is the default (leftIndent, 0 spacebefore,
...) according to the PDF 1.4 reference.
