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

Add support for movie annotations.

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.

 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.

By specification, FitH destinations are defined with page and top position. A null value for top specifies that the current value of that parameter is to be retained unchanged. However, importing such a document with PdfProcessing leads to ArgumentOutOfRangeException:  'Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index'.

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.

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

OutOfMemoryException has thrown when creating a thumbnail with the ThumbnailFactory.

This behavior is observed with binaries version 2020.2.513 or later.

Exported checkbox fields have state "/On " instead of "/Yes ". 

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.

KeyNotFoundException exception is thrown when the platform type is MacintoshNonSymbolic and the encoding is WinAnsiEncoding.

Exception when trying to import symbols with the ZapfDingbats font

Currently Type0Font class has CMap that can only be Identity-H.

In PDF, symbolic font programs, such as ZapfDingbats, have built-in encodings that are usually unique to each font, and ordinary their encoding cannot be overridden. When importing a document using a symbolic font with defined encoding, which overrides the build-in encoding, a KeyNotFoundException: 'The given key was not present in the dictionary.', is thrown.

In the PDF specification, if the font name consists of two words, they are separated by a dash (e.g. Times-Roman).
Provide support for Standard Fonts separated by blank space (e.g. Times Roman).

Currently, the implementation of the PdfFormatProvider supports the import of Link and Widget annotations. However, other annotation types, such as Text and Pop-up annotations, are imported with limited support - only some of their visual appearance properties are imported. This leads to unpredictable results when exporting or merging. However, the exception could be avoided and the annotation can be skipped. This will ensure the client application is running without errors.

Annotation types may be seen on page 615 in PdfReference 1.7.

There is a wrong reference in the WPF .NET Core version of Telerik.Windows.Document.Fixed.dll that causes a FileLoadException with the message "Could not load file or assembly 'System.Drawing.Common, Version=5.0.0.0'"

Workaround: Add NuGet reference to System.Drawing.Common, version 5.0.0.0. Note: mark "Include prerelease" so you can see it in the NuGet Package Manager

When the resources of a FormXObject are defined using indirect reference, an InvalidCastException is thrown while parsing the document content.

Provide API for enforcing the use of only FIPS 140-2 compliant hashing algorithms.
