or there should be an optional parameter "bool AcceptNewlines" or "bool IgnoreNewlines"

 

Currently, this can be implemented like this:

private void InsertTextWithNewlines(Block block, string text)
{
    string[] lines = text.Split(new[] {"\r\n", "\r", "\n"}, StringSplitOptions.None);

    for (int i = 0; i < lines.Length; i++)
    {
       block.InsertText(lines[i]);
       if (i < lines.Length - 1)
       {
          block.InsertLineBreak();
       }
    }
}

Release R1 2021
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.
