German umlauts (the characters 'Ä', 'Ö', 'Ü', 'ä', 'ö' and 'ü') will not be printed to a generated pdf file, but the other German "special" character "ß" works.

 

I use the trial version via the Telerik NuGet feed. A test program and my locally generated file are attached.

A remote go-to action is similar to an ordinary go-to action but jumps to a destination in another PDF file instead of the current file.

PdfProcessing: Signature field validation fails if a document is imported from a byte array of CopyStream property is false.

Workaround: Set the CopyStream property of the ImportSettings to true:

PdfFormatProvider formatProvider = new PdfFormatProvider();
formatProvider.ImportSettings.CopyStream = true;

Inserting a table with more than 10K rows is very slow.

Workaround: 

Use the following approach with SpreadStreamProcessing,SpreadProcessing and PdfProcessing:

 1) Generate an xlsx document with RadSpreadStreamProcessing 
 2) Import the document from 1) with RadSpreadProcessing 
 3) export 2) to PDF

The CIDToGIDMap value is exported as an indirect object. When the value is a PdfString ist should be directly exported and not referred as an indirect object. 

A StackOverflowException is thrown when cloning documents containing a page containing links to the same page. 

More information is available in the Pdf Reference 1.7. Page 442 lists all predefined CMaps that should be imported and exported as PdfName objects. At this point, trying to import a document with such encoding, a NotSupportedException is thrown with message Encoding type is not supported.

OutOfMemoryException has thrown when creating a thumbnail with the ThumbnailFactory.

This behavior is observed with binaries version 2020.2.513 or later.

In Adobe Acrobat, if you bring up the "Document Properties" dialog window and then click on the "Advanced" tab, there is a property under the "Print Dialog Presets" section called "Page Scaling". We should preserve the value on import/export and be able to set it in the code behind.

Importing document containing TextBox widgets with NormalContentSource defining text properties, such as FontSize and Position, are exported with incorrect appearance when the value of the field is modified.

The checkbox state is not correctly imported when the value is not specified

AcroForms are not saved when splitting a document into pages. This leads to forms not being recognized when the file is imported back.

By specification, the InteractiveForm fields can have the same name if they are descendants of a common ancestor. Such fields are different representations of the same underlying field; they should differ only in properties that specify their visual appearance. When such a document is imported an ArgumentException: 'An item with the same key has already been added.' is thrown.

 InvalidCastException when importing a file with missing space. The file contains no space between the objects declarations and the page content and this is why the exception occurs.

NullReferenceException has thrown when importing a form XObject with null Resources in PDF dictionary.

When importing a VariableContent widget with OpenType font, which fails to read the post table of the font file, a NullReferenceException is thrown when the RecalculateContent() method is called.

Workaround: Change the widget font:

foreach (Widget widget in textBoxField.Widgets)
{
    widget.TextProperties.Font = FontsRepository.Helvetica;
    widget.RecalculateContent();
}

Telerik Pdf Processing Cannot open the attached pdf file and exception occur.

Currently adding an Image content element with ImageSource instantiated with a GIF file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

The underline gets over the text when the line spacing is set to exact, spacing after is set to 0, and the font size is less than 12.
