The Form object does not inherit the graphics state of the page

NullReferenceException is thrown when importing a PDF document containing InlineImage with missing parameters

Currently, the ListLevel object doesn't provide an API for changing the passing of the Bullets.

At this point, the setting paragraph Borders is not supported.

A possible workaround could be to draw a rectangle around the desired Block.

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

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. 

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

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;

Wrong encoding is used when the PDF file contains font with custom encoding

Workaround:

System.ArgumentException when setting a password to a document with form fields

Exception when merging file that contains notdef characters with PdfStreamWriter

When using the Telerik.Documents.ImageUtils.JpegImageConverter default implementation in Blazor WebAssembly application the Magick.NET library doesn't load all of its assemblies.

Workaround:
Create a custom implementation of the JpegImageConverterBase class: Create Custom JpegImageConverter in .Net Standard.

According to the Pdf Reference, a rectangle is written as an array of four numbers giving its coordinates. However, specific documents contain the numbers for the rectangles for the Type0Font's bounding box as indirect references. Trying to import such a setup results in an ArgumentException "The IndirectReference type cannot be converted to a real numeric value.".

According to the CMap specification (page 49): Overlapping codespaces are not permitted.

When a TextBox field has a smaller size than the default padding of the field an exception is thrown: ArgumentOutOfRangeException: width should be greater or equal than 0. (Parameter 'width')

Currently, importing a document with non-embedded TrueType font will result in a font instance with an empty font source. Support should be added for providing custom font data of TrueType fonts during document import.

By specification, the last line of the file contains only the end-of-file marker, %%EOF. If the file contains many trailing bytes at its end, a NotSupportedException: 'StartXRef keyword cannot be found.', is thrown.

Workaround: Trim any content after the end-of-file marker (see FixInvalidEndOfFile). 

I have read that there limitations to PDF files being imported, however, the file being imported  was generated with FixedContentEditor, so, should be able to import?

  using (Stream stream = Stream)
        {
          try
          {
            this._document = provider.Import(stream);
            _InputPath = fileName;
          }
          catch (Exception e)
          {
            Errors = "Could not open file " + fileName + ": " + e.Message;
            this._document = null;
          }
        }
      }

Currently, there is such an option using the FixedContentEditor`s DrawWidget() method.
