Hi there I have a pdf and whenever I try to Import the PDF file into PdfFormatProvider.Import method for flattening purposes, it throws null reference exception.

I have added a sample .net project with PDF added as source. You just need to run the project on your end. I am using version 2023.3.1106 of document processing library.

I am using ASP.NET 4.8 framework.

Thanks

Some fonts don't include bold and italic font styles. These fonts can be exported with the default typeface, and additional transformation could be applied to the letters itself - e.g. skew transform for the italic.

Note: Make sure that this will also work when exporting to PDF in WordsProcessing.

For example exporting the text "\uD83D\uDE0A" with "Segoe UI Symbol" font family should export a single smiling face. Instead the characters are skipped during the export as PdfProcessing is trying to export them as separate char values ("\uD83D" and "\uDE0A") and the font does not contain glyphs corresponding to these char codes.

StackOverflowException when importing a document with style based on itself.

Use the following code to strip the faulty "based on" definition from the RTF:

RtfFormatProvider provider = new RtfFormatProvider();
var rtf = File.ReadAllText(ofd.FileName);
rtf = this.ReplaceSelfBasedOnStyle(rtf);
this.flowDocument = provider.Import(rtf);

...

private string ReplaceSelfBasedOnStyle(string rtf)
{
    string pattern = @"{[\n]*\\s[0-9]+[^;]* \\\w* (Normal);}";

    var matches = Regex.Matches(rtf, pattern);
    foreach (Match match in matches)
    {
        string oldValue = match.Value;
        string newValue = oldValue.Replace(@"\sbasedon0 ", string.Empty);

        rtf = rtf.Replace(oldValue, newValue);
    }

    return rtf;

Steps to reproduce:

1.Create a zip archive for a txt file with password protection

2. Try updating the protected file and insert a new text line for example

The settings used for decrypting the file don't seem to be used encrypting again after the update operation. Here is a sample code snippet for reproducing the error message:

    Sub Main()
        Dim sZipFilePath As String = "..\..\test.zip"
        File.Delete(sZipFilePath)

        CreateArchive(sZipFilePath)

        Dim decryptionSettings As DecryptionSettings = EncryptionSettings.CreateDecryptionSettings()
        AddHandler decryptionSettings.PasswordRequired, AddressOf DecryptionSettings_PasswordRequired
        Dim compressionSettings As CompressionSettings = Nothing
        Dim encoding As Encoding = Nothing
        Using oFS As FileStream = File.Open(sZipFilePath, FileMode.OpenOrCreate)


            Using oArchive As ZipArchive = ZipArchive.Update(oFS, encoding, compressionSettings, decryptionSettings)
                For Each entry As ZipArchiveEntry In oArchive.Entries
                    Using entryStream As Stream = entry.Open()
                        Dim reader As New StreamReader(entryStream)
                        Dim content As String = reader.ReadToEnd()

                        entryStream.Seek(0, SeekOrigin.End)
                        Dim writer As New StreamWriter(entryStream)
                        writer.WriteLine("Updated line.")
                        writer.Flush()
                    End Using
                Next
            End Using
        End Using
    End Sub

    Private Sub CreateArchive(sZipFilePath As String)
        Using stream As Stream = File.Open(sZipFilePath, FileMode.Create)
            Dim encryptionSettings As PasswordEncryptionSettings = encryptionSettings.CreatePkzipPasswordEncryptionSettings()
            encryptionSettings.Password = "MyPassword"
            Dim compressionSettings As CompressionSettings = Nothing
            Dim encoding As Encoding = Nothing

            Using archive As ZipArchive = ZipArchive.Create(stream, encoding, compressionSettings, encryptionSettings)

                Using entry As ZipArchiveEntry = archive.CreateEntry("text.txt")
                    Dim writer As StreamWriter = New StreamWriter(entry.Open())
                    writer.WriteLine("Hello world!")
                    writer.Flush()
                End Using
            End Using
        End Using
    End Sub

    Private Sub DecryptionSettings_PasswordRequired(ByVal sender As Object, ByVal e As PasswordRequiredEventArgs)
        e.Password = "MyPassword"
    End Sub

The stream that is internally created by the CreateFromDirectory method remains opened and the user can't close it:

This is error message observed when using the below code snippet:

The process cannot access the file 'C:\Users\dyordano\OneDrive - Progress Software Corporation\MyProjects\1640071ZipFileCreateFromDirectory\myzip.zip' because it is being used by another process.

        static void Main(string[] args)

            string archiveFileName = @"..\..\myzip.zip";
            string sourceDirectoryName = @"..\..\Folder";

            return empty;
        }

Note: We should ensure that all of the obsolete API that used to use the "leave open" flag don't keep the stream locked.
