When a PDF document is being imported, some of the characters may experience unexpected results while reading the font.

NOTE: the document is displayed in the MAUI/WPF/WinForms PdfViewer controls with missing parts of the text.

When exporting the pdf pages as images with the Skia engine, some parts of the document got missing.

Note: In the previous Version 2024.3.806 these parts appeared.

An ArgumentNullException is thrown when importing a document with a missing required MediaBox operator in the Page object ("ArgumentNullException: 'Value cannot be null.")

When loading some PDF documents with German culture, part of the text got missing.

Workaround: set English culture before loading the document

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");

RadPdfProcessing currently supports interactive forms whose data is defined directly in the document. To preserve them when importing and exporting documents, add support for import-export interactive forms based on the Adobe XML Forms Architecture (XFA).

From PDF 2.0 the XFA forms are depreciated.

Following the steps:

1. Create two PDF documents that contain form fields where the name contain a period, e.g. "person1.name".

2. Merge the two documents:  https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/model/interactive-forms/form-fields/formfields#merging-documents-with-form-fields 

SkiaImageFormatProvider: Add support for Text, TextMarkup, Line, and Stamp annotations.

Currently, these annotations are omitted on image export.
