Currently, signature flags, represented by the 'SigFlags' optional entry, are not imported and exported, and there is no API for setting them.
As a result, documents signed with RadPdfProcessing (or with RadPdfViewer) appear in Adobe Reader without the blue document message bar at the top (the analogue of the RadPdfViewer's SignaturePanel).
If the API is supported, setting the flag to 1 or 3 would ensure that the message bar would be visualized in Adobe Reader.
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.
Splitting a row leads to copying all rows below it. During that operation, the information for the row height is lost, when the previous row has a cell spanning on the split one, leading to a missing row in the exported document.
The issue is a regression introduced in R1 2021.
Currently RadFixedDocumentInfo is used only for export of Author, Title and Description document metadata properties. This should be extended to support custom properties. We should also implement the import of RadFixedDocumentInfo.

According to PDF specification, all fonts should be embedded except from 14 Standard PDF fonts. This guarantees that the PDF file is self-contained and will be rendered successfully on different devices and operation systems. However, some clients prefer not to embed fonts in order to reduce file size. That is why we may provide such API.

Currently, for .NET Framework scenarios, this could be achieved using RadPdfViewer's WPF control ThumbnailFactory class. Sample code may be seen at this forum post: http://www.telerik.com/forums/pdf-thumbnail-returns-transparent-images#jO33X-E8Cki_qLh_KsToWg.
The feature should be implemented for .NET Standard as well.
When a row has two cells and the content of the first one is large, the width of the second cell results in too small value while measuring and its content remains invisible.
Workaround: Set PreferredWidth to the second cell.
Table table = new Table(); TableRow row = table.Rows.AddTableRow(); row.Cells.AddTableCell(); TableCell secondCell = row.Cells.AddTableCell(); secondCell.RowSpan = 2; table.Measure(); table.Rows.AddTableRow();
According to the PDF Specification: The first entry in the table (object number 0) is always free and has a generation number of 65,535;
