When exporting with  TaggingStrategyType.Build, automatic table detection can include surrounding content in the table and generate rows, cells, and header associations that do not match the document’s logical structure. Headings may become table-cell content instead of remaining separate elements.

The exported PDF may pass automated accessibility validation despite having incorrect semantics for screen readers.

Provide a public API for setting the Scope attribute on explicitly created table-header (TH) structure elements.

Currently,  StructureElement.Attributes,  StructureElementTableAttributes, and  TableScopeAttribute are internal. Applications can create TH elements but cannot directly specify whether headers apply to a row, column, or both.

This prevents PDF/UA-1 compliance when table relationships are not defined through Headers and IDs.

Add a setting to choose whether import continues or throws when invalid structure-tree data is detected. Default behavior continues import, skipping invalid entries without repairing them.

Excessive text wrapping and row heights due to columns collapsing to excessively narrow widths when the total column width exceeds the table width.

Regression in versions after 2026.3.810.

Workaround: Manually readjust the column Width values.

Release 2026.3.1014 (2026 Q3)

Handle the import of documents that have an invalid boolean value for the PrintScaling property of ViewerPreferences. The expected value of the /PrintScaling entry is a PDF name object:

/PrintScaling /None
/PrintScaling /AppDefault

When importing such documents, the following exception is thrown: 

InvalidCastException: 'Unable to cast object of type 'Telerik.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfBool' to type 'Telerik.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfName'.'

Release 2026.3.1006 (2026 Q3)
Importing the attached PDF throws InvalidCastException while parsing its structure tree. A /Layout attribute sets /BorderThickness to integer scalar 1. ISO 32000-1:2008 allows this value as a number or a four-entry array; a scalar applies to all four edges. The importer handles real values and arrays, but not PdfInt.

Setting PdfImportSettings.IgnoreMarkedContent to true currently skips marked-content containers but still imports the structure tree, so it does not avoid the exception.

Expected: Import integer and real scalar values as thickness for all four edges; preserve four-entry array values. When IgnoreMarkedContent is true, skip structure-tree import while still importing pages.
