"Validation of an electronic signature requires data to validate the signature such as CA certificates, Certificate Revocation List (CRLs) or Certificate status information (OCSP) commonly provided by an online service (referred to in the present document as validation data). If the document is stored and the signatures are to be verifiable long after first created, in particular after the signing certificate has expired, the original validation data may no longer available or there may uncertainty as to what validation data was used when the document was first verified."
Images could have orientation set in their metadata:
Workaround: Rotate the image before inserting it into the RadFixedPage (check the attached project).
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.
This case can be handled using the Handling Exceptions mechanism.
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.
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.

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.
When a Table consisting of one TableRow that contains a TableCell with a Rowspan > 1 set, additional lines are added to the table.
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();
