Subject: Print Orientation

I'm creating a small application to print tiff-f images attached to emails. It always prints landscape, I've tried using transform to rotate 90degrees but it still prints landscape. I also check the image by loading it into a visible TImage without an orientation problem. The code is as follows:

procedure TForm1.POPAfterRetrieve(Sender: TObject);
var
Files,
Page: integer;
CanDelete: Boolean;
Graphic: TDibGraphic;
TiffStream: TMemoryStream;
GraphicPrinter: TDibGraphicPrinter;

begin
GraphicPrinter := TDibGraphicPrinter.Create;
GraphicPrinter.PrintMode := pmFullPage;
GraphicPrinter.TopMargin := 0.25;
GraphicPrinter.LeftMargin := 0.25;
GraphicPrinter.Height := 10.5;
GraphicPrinter.Width := 8.0;

Graphic := TTiffGraphic.Create;
TiffStream := TMemoryStream.Create;

CanDelete := True;
try
for Files := 0 to Msg.AttachedFiles.Count-1 do
begin
TiffStream.Clear;
TiffStream.LoadFromStream(Msg.AttachedFiles.Items[Files].BodyBin);
for Page := 1 to Graphic.GetImageCount(TiffStream) do
begin
try
Graphic.Clear;
TiffStream.Seek(0, soFromBeginning);
Graphic.ImageToLoad := Page;
TiffStream.Seek(0, soFromBeginning);
Graphic.LoadFromStream(TiffStream);
Image.Picture.Graphic := Graphic;
Image.Invalidate;
GraphicPrinter.Print(Graphic);
except
StatusBar.Panels[1].text := 'Invalid Page!';
CanDelete := False;
end;
end;
end;
finally
GraphicPrinter.Free;
TiffStream.Free;
Graphic.Free;
end;

if CanDelete then
POP.DeleteMessage(1);
end;
