With the current implementation, the Trigger Events are skippet on import.

From the PDF Specification: An annotation, page object, or interactive form field may include an entry named AA that specifies an additional-actions dictionary that extends the set of events that can trigger the execution of an action.

When calling the RadFixedDocument`s Clone() method the RadFixedPage`s MediaBox and CropBox are not copied.

Attempting to open a Pdf document containing an unsupported action type results in a NotSupportedActionException being thrown (see PdfProcessing: Add support for actions of type Launch).

 

Can the behavior be changed to ignore unsupported actions and allow the document to be opened?

 

With the current implementation, the Standard Fonts preloaded in the FontsRepository cannot be replaced.

An exception when the NormalContentSource of a widget is null and one flatten the form fields 

This type of action is currently not supported and a NotSupportedActionException is thrown when accessing such an object.

These exceptions can be handled using the Handling Exceptions mechanism.

Watermark transparency is not imported correctly

When importing a document containing a specific image stream an exception is thrown.

Implement async PDF conversion from RadFlowDocument and Workbook

When importing a document containing an inline image that starts with spaces a NullReferenceException is thrown.

The checkbox state is not correctly exported when the value is specified.

According to the PDF specification (Adobe® Portable Document Format Version 1.7), the appearance dictionary is optional and it is specifying how the annotation is presented visually on the page.

Exceptions thrown:

InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfNull' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Annotations.Appearance'.'

NullReferenceException: 'Object reference not set to an instance of an object.'

When importing such documents an InvalidDataException (Unknown compression method <method-name>) is thrown.

According to the current .ZIP File Format Specification these methods are 7, 11, 13, 15, and 17.

Compression method:

        0 - The file is stored (no compression)
        1 - The file is Shrunk
        2 - The file is Reduced with compression factor 1
        3 - The file is Reduced with compression factor 2
        4 - The file is Reduced with compression factor 3
        5 - The file is Reduced with compression factor 4
        6 - The file is Imploded
        7 - Reserved for Tokenizing compression algorithm
        8 - The file is Deflated
        9 - Enhanced Deflating using Deflate64(tm)
       10 - PKWARE Data Compression Library Imploding (old IBM TERSE)
       11 - Reserved by PKWARE
       12 - File is compressed using BZIP2 algorithm
       13 - Reserved by PKWARE
       14 - LZMA
       15 - Reserved by PKWARE
       16 - IBM z/OS CMPSC Compression
       17 - Reserved by PKWARE
       18 - File is compressed using IBM TERSE (new)
       19 - IBM LZ77 z Architecture 
       20 - deprecated (use method 93 for zstd)
       93 - Zstandard (zstd) Compression 
       94 - MP3 Compression 
       95 - XZ Compression 
       96 - JPEG variant
       97 - WavPack compressed data
       98 - PPMd version I, Rev 1
       99 - AE-x encryption marker (see APPENDIX E)

Writing a page to a stream with resources, defined with names including space or dash characters, are not exported using an escape sequence.

Provide support for inserting transparent images in Net Standard

Adding a table with the same code leads to different results 

When adding 10 identical tables onе or more have missing rows at the bottom. The seems to be caused by the text measurement. 

Some operators cannot be correctly parsed which causes incomplete import/export

The executing of the PostScriptReader`s Read method takes a lot of time when iterating content streams with many Path geometries.

There are many instances of the internal Transition, State and ImageXObject classes.

Currently, RadFixedDocumentInfo is used only for the export of Author, Title, and Description document metadata properties.
