Here is the PDF. http://www.b2ss.net/textandpicture.pdf ... when I use qpdf to render the PDF only the image is visible the text is not... why? what can i do to get it work properly? Please help.

thanks in advance.

I forgot to mention: i'm using DELPHI DCU version from delphi and the method RenderPAgeToStream, the problem appears there. When I use .NET C# and ActiveX control - renderdocumenttofile, it's working perfectly...

Hi!

The dcu-version is 5.21 and the activex is 5.22. I think Marian had made few improvements in the 5.22-version - they are missing in the 5.21-version. So it's like it is. You can use the activex-version or you can pay Marian to do this improvements in the dcu-version for you personal, too.

Best regards,
Ingo

I could use the activeX version. Can anyone please send me an example for using RenderPageToStream in delphi?

ps: How much for the 5.22 DCU version?

Hi!

Marian don't share the new 5.22 code for free. If you want to buy it you can ask at him at support [ at ] quickpdf [ dot ] org.

Best regards,

Sample of using QuickPDF.RenderPageToStream.

procedure RenderPageToStream(

Pdf : IQuickPDF2;

Stream : TStream;

PageResolution: Integer = 110; // usualy used is 72; acrobat use 110.

ImageType: Integer = 0; // 0 is BMP; 3 is JPG; 4 is GIF; 5 = PNG

ZoomFactor: Double = 1; // 1 = 100%

PageRotation: Integer = 0); // possible values are: 0, 90, 180, 270

var

istm : ActiveX.IStream;

begin

ASSERT(Assigned(Pdf));

ASSERT(Assigned(Stream));

        istm := TStreamAdapter.Create(Stream, soReference);
        try
            Pdf.RenderPageToStream(
                PageResolution,
                Pdf.SelectedPage,
                ImageType,
                istm,
                ZoomFactor,
                PageRotation);
        finally
            istm := nil; // will release the StreamAdapter !!!
        end;
end;
