When applying MultipleSubstFormat1, an exception is thrown: "NullReferenceException: 'Object reference not set to an instance of an object.'"

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

In Q2 2025 we introduced the MarkedContent in a RadFixedDocument.

This error happens when importing a document.

Handle documents with mismatched font Subtype and FontFile type when exporting PDF to image with SkiaImageFormatProvider.

The StokeAlphaContant is not handled correctly when applied on a TextFragment:

Wrong clipping order when exporting a document with MarkedContent leads to a missing content.

The standard fonts listed at http://docs.telerik.com/devtools/wpf/controls/radpdfprocessing/concepts/fonts#standard-fonts cannot be embedded in a document. Using one of them prevents the document from complying with PDF/A standard.

Manually set form field values are not preserved when opened in Adobe Acrobat.

Implement GetColor method for IndexedColorSpaceObject.

When exporting a PDF page to an image with the SkiaImageFormatProvider the following error occurs: 

System.IndexOutOfRangeException: 'Index was outside the bounds of the array.'

Missing spaces from TextFragments when exporting to plain text.

Error message: 

System.InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Forms.FormFieldsTree' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfArray'.'

Specific TextFragments that are positioned a little further from the previous text are incorrectly recognized as word start by the text recognizer engine and result in additional white spaces in the exported text.  

InvalidCastException is thrown due to incorrectly parsed stream dictionary.

Import-export changes the color of the shading object.

Add support for "AcroSendMail:SendMail" named action.

Such a document can be considered as invalid. However, it would be good to provide functionality to handle it.  

Wrong font loading when FontFile2 is CFF (Compact Font Format).

Implement functionality to support scenario when a document which already has a signature to be signed again or add two or more signatures.
