Nice one Ingo -- much better than Notepad for a production environment. :-)]]> Tue, 24 Aug 2010 20:36:20 +0000 http://www.quickpdf.org/forum/jbig2-support-will-be-in-722_topic1545_post6902.html#6902 <![CDATA[JBIG2 support will be in 7.22 : Hi!In a production environment...]]> http://www.quickpdf.org/forum/jbig2-support-will-be-in-722_topic1545_post6900.html#6900 Author: Ingo

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

Ah, yup. The file does indeed contain JBIG2 compressed images. This would be my problem.
 
In that case, I look forward to the beta in a few weeks with JBIG2 support. :)

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.

How do we know if a PDF uses JBIG2? I have a few PDFs that print out as blank documents when using QuickPDF and I had read that it may be because of JBIG2 support.

If this one does in fact contain JBIG2 then I will send it to you for testing.

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

This is really a good news and I'm looking forward to it. Just to add to that ... it will be really helpful if QP extends its support for HTML Tags. This will ease the process of making some typical PDF reports without much of PDF-styling effort.]]> Mon, 23 Aug 2010 04:13:26 +0000 http://www.quickpdf.org/forum/jbig2-support-will-be-in-722_topic1545_post6881.html#6881 <![CDATA[JBIG2 support will be in 7.22 : Hi Guys,I just thought you might...]]> http://www.quickpdf.org/forum/jbig2-support-will-be-in-722_topic1545_post6862.html#6862 Author: Rowan

Hi Guys,

I just thought you might like to know that the next version of Quick PDF Library will include JBIG2 support. We'll have a public beta ready in the next 1-2 weeks, perhaps sooner, that you can try out.

If you have any PDF files that use JBIG2 images that you'd like me to add to our repository of test files, please email it to rowan.hanna@debenu.com.

Cheers,
- Rowan.
