Support import of images defined with v:imagedata element (VML Object) in Docx

Add support for GoToR action

Note: related item: PdfProcessing: Introduce functionality to preserve GoToR actions during import/export

Provide API for inserting Watermarks that depend on Optional Content / PDF Layers (Not to be confused with Watermark Annotations).

With the current implementation, the documents containing Standard Fonts are not PDF/A compliant (check How to Comply with PDF/A Standard).

PdfProcessing: Invalid annotation position leads to missing content.

From the PDF specification: "The current stroking alpha constant, specifying the constant shape or constant opacity value to be used for stroking operations in the transparent imaging model."

Not respecting it leads to lost image transparency.

In version 1 there are three profiles that have different levels of detail in their structure: Basic (B), Comfort (C) and Extended (X): https://mind-forms.de/e-rechnung/welches-zugferd-profil-kann-ich-verwenden/ 

The use case we should cover is make stamp or other signatures immovable.

When cloning or merging a document containing a Link with Actions collection an exception is thrown: NullReferenceException: 'Object reference not set to an instance of an object.'

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.

Handle the import of documents with Associated Files (/AF) elements whose content is set to null.

PdfProcessing: ArgumentException is thrown when importing a document with a duplicated filed names.

System.ArgumentException: 'An item with the same key has already been added. Key: Telerik.Windows.Documents.Fixed.Model.InteractiveForms.RadioButtonField'

It is reproducible when you have at least 2 pages with RadioButtonFields. The import operation goes smoothly. However, merging or removing a page after import leads to the described error.

Matte color is used for preblending images with some background color, using the SMask. Matte color is specified using the optional 'Matte' entry for the SMask object.

See PDF 1.7 specification, page 554-555:

Matte
array
(Optional; PDF 1.4) An array of component values specifying the matte color with which the image data in the parent image has been preblended. The array consists of nnumbers, where n is the number of components in the color space specified by the ColorSpace entry in the parent image’s image dictionary; the numbers must be valid color components in that color space. If this entry is absent, the image data is not preblended.

Add a setting that allows enabling printing of protected documents.

The issue is reproducible only with nested tables - tables positioned inside some other table cell. When using simple tables the text is always wrapped and rendered correctly. This may be used as a workaround for scenarios which allow replacing nested tables with simple ones.

This may cause either big distance between some glyphs, or overlapping glyphs.

As some other decoders, JBIG2 may also handle different parameters in order to correctly decode the stream. Currently, decode parameters are not supported for this decoder.

The NotImplementedException is thrown while getting the color from unsupported color space (for example ICC). This exception occurs during the import of shading patterns with gradient stops using this color space or during the import of tiling pattern with underlying color space.
