XlsFormatProvider: Add support for hidden rows.

Add support for superscript and subscript font effects for cell formatting. Currently, this is not supported by the model and is omitted on import.

Introduce an API for Cloning RadFixedPages.

Implement the Exponential Interpolation Function in PdfProcessing. Currently, NotSupportedFunctionTypeException is thrown with a message "Function type 2 is not supported."

At this point, XlsFormatProvider doesn't support images and they are not imported into Workbook while reading an .xls file.

Add support for strikethrough font effect for cell formatting. Currently this is not supported by the model and is omitted on import.

With the current implementation when exporting a Stitching function all the containing functions are exported as Sampled functions even if they originally have been imported as Exponential interpolation functions, which leads to an increase in the size of the document.

More information can be found in the PDF Specification.

At this point XLS import of SpreadProcessing does not have support for notes/comments.

Add support for PDF Portfolios.

With the current implementation, the compression setting is omitted:

• streamWriter.Settings.StreamCompression

Introduce support for TimeStampServer when using the PdfStreamSigner.

Handle the import of documents when the GoToR action`s file specification object is a string.

When importing a large document (e.g. 2.3GB) , the library fails to parse int value that exceeds the limit which leads to endless importing:

Some PDF files have an additional content added before the file header (before %PDF-1.4 for example). This additional content makes all byte offsets in the document invalid, which causes the format provider to throw an exception.

At this point, to import a similar document it should be pre-processed so the content before the version header is removed before importing it.

Handle the import of documents with invalid offset and no space before dictionary keys.

Handle the import of documents with a negative cross-reference stream offset.

Add support for Border annotation property.

Documents can be signed using the end certificate of a certificate chain, instead of the whole chain. This improves the performance of the signing.

With the current implementation, the documents containing Standard Fonts are not PDF/A compliant (check How to Comply with PDF/A Standard).
