PDF-Creation Problem

edited January 2008 in Devices
Hi all,

I have a problem with the RB 10.07 and the TpdfDevice. In a Intraweb
Application I generate a PDF.
On some systems (mostly XP) it is working perfectly. On Windows Server is
does not work.

With each print the size of the output stream differs. The first output is
ok, but the second and consecutive prints are scrambled.

Below is the code which generate the report. Is there something I have
missed or special in an IntraWeb-Application?

Var
fOutputStream : TMemoryStream;
lPDFDevice: TppPDFDevice;
PlanName : String;
begin
lPDFDevice := TppPDFDevice.Create(nil);
try
FOutputStream := TMemoryStream.Create;
try
lPDFDevice.PDFSettings := PPlan.PDFSettings;
lPDFDevice.OutputStream := FOutputStream; // assign output
stream
lPDFDevice.Publisher := PPlan.Publisher;

PPlan.Template.FileName := UserSession.WorkingDir+'PERSPLAN.RTM';

PPlan.Template.LoadFromFile;
PPlan.TextFileName := PlanName;

PPlan.PrintToDevices;

finally
WebApplication.SendStream(foutputStream, true, 'application/pdf',
'PersonalPlan.pdf');

end;
finally
lPDFDevice.Free;
end;
end;
-- Output Stream will be freed by IntraWeb

    Hi Sven,

    How does the output stream differ when you create it with your server app?
    Are you still getting a valid PDF file? If you save the PDF to file before
    sending it over the server, is it already corrupt?

    Hi Nico,

    The pdf is mostly valid. (it has a correct start and end header). And yes,
    it is corrupt before sending. I had the fear that this was a problem with
    the builtin pdf engine. I tried it with gnostice and it looks good. We were
    happy.....

    But we just moved one hour ago from the dev system to the prod system and
    now we have the same "shit". Argh. So it could not be the pdf engine device.

    We are using regions and they are streched over the complete page and the
    labels are invisible.

    I can send you two pdf if you want...

    Best regards

    Sven



    (sorry, i send this to support@.....)

    We are now a step forward. We are stable (hopefully) on the production
    system because we installed a printer driver on the system. It looks that if
    there is no printer driver installed, the regions does have a problem. They
    are stretching and are in the foreground. Does this make sense for you?

    Hi Sven,

    Sorry for the delay in this response, I somehow lost track of this thread.

    I did a test on a machine with no printers installed and was able to
    successfully export a report with stretchable regions to PDF without any
    problems. Are you able to recreate this issue on any other machines with no
    printers or just the Windows Server one?

    Hi Nico,

    I can create this on systems with XP (in a VM) and/or Windows Server 2003
    (Standard/Web).
    If I just install a printer the problem seems to be gone. (I run this within
    Atozed Intraweb)

    I have here two pdf outputs to show it. Can I send it to you by mail?

    Greetings

    Hi Sven,

    Yes, please send the PDF to support@digital-metaphors.com with the
    PDFSettings.Compression property set to clNone and I'll take a look at them
    for you.
