The issue is not reproducible in Q1 2025 (2025.1.205).

In Q2 2025 we introduced the MarkedContent in a RadFixedDocument.

Currently the DocumentInfo property is for export purposes only and meta information about documents is stripped when importing.

According to the PDF specification (ISO 32000), the document info dictionary (often called "metadata" or "Info" dictionary) can include the following standard fields:

Title: The document’s title.
Author: The name of the person who created the document.
Subject: The subject of the document.
Keywords: Keywords associated with the document.
Creator: The application that created the original document.
Producer: The application that converted the document to PDF.
CreationDate: The date and time the document was created.
ModDate: The date and time the document was last modified.
Trapped: Indicates whether the document has been trapped (a printing term).

These fields are stored in the PDF’s Info dictionary and are used by PDF viewers for display, search, and indexing.

It would be great if the SkiaImageExportSettings offer a DocumentUnhandledException event allowing the developer to handle specific errors when exporting to image formats.

This would be an essential improvement in the existing Exception handling mechanism and would enable exporting PDF documents to images even though some parts of the image may not be completely supported: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/features/handling-document-exceptions
