Subject: TIFF Image is displayed upside down

I have TIFF image which has been scanned than rotated 180 degrees and than saved into file. That file is transferd to the and user. When end user opens this file (I use TImageScrollBox to display it), the image is displayed upside down. If I save this image from MemoryStream into a file right before I load it into TImageScrollBox (LoadFromStream or LoadFromFile) it still displayed upside down, but I can open the same file using Imaging for Window and it will display it correctly. Even if I open the same file in TImageScrollBox at design time it still shown upside down.

Here is the snippet of my test code:

imgvar: Variant;
ms: TMemoryStream;
imgChartImage: TImageScrollBox;


//Get image as variant
imgvar := dmCMIS.scnFileNet.AppServer.GetImage(dr.DocID, dr.PageNo);
if Assigned(ms) then ms.Free;
ms := TMemoryStream.Create;
ms.Position := 0;
//Convert variant into stream
VariantToStream(imgvar, ms);

ms.Position := 0;
//The saved image is displayed property in Windows Imaging

ms.Position := 0;
//After the same image is loaded into TImageScrollBox it
//displayed upside down
imgChartImage.LoadFromStream(ms, 0);
