JBIG2 support will be in 7.22

Hi Guys,

Glad to hear you're excited by this news. We'll also look at extending HTML tag support. Cheers!

Open the PDF in notepad and then search for JBIG2. That usually does the trick (although, it won't pick up every instance of JBIG2 compression). But if you email the files to me I will check them out regardless of whether it's a JBIG2 related issue.

Hi!

In a production environment you won't use Notepad to check for JBIG2 ;-)
Read the pdf-file-content into a stream/string and check the content with the Pos-syntax.
Here's a small sample (Delphi):

   var fs           : TFileStream;
       textkomplett : String;
// . . .
   Edit1.Text := 'c:\temp\sample.pdf';
   textkomplett := '';
   fs := TFileStream.Create(Edit1.Text,fmOpenRead+fmShareDenyWrite);
   try
     SetLength(textkomplett,fs.Size);
     fs.Read(PChar(textkomplett)^,fs.Size);
   finally
     fs.Free;
   end;
// . . .
   Result := Pos('JBIG2', textkomplett);

Cheers, Ingo
