Subject: Conversion to TImage and Bitmap confusion

I'm using WitsEnd's barcode package to recognize a barcode on a scanned page and it refuses to work with a .Graphic.BitmapHandle from the Envision TImageScrollBox component but it works fine with a .Picture.Bitmap.Handle from the TImage component

I've tried many things but this it what it boils down to:

ImageScrollBox : TImageScrollBox;
Image1 : TImage;


ImageScrollBox.LoadFromFile( 'g:\scandocs\test.bmp', 0 );

{this is probably the wrong way to do this and what I need help with}
Image1.Picture.Graphic := ImageScrollBox.Graphic;

{this works - it saves a file that is identical to the one loaded above}
Image1.Picture.SaveToFile( 'g:\scandocs\testx.bmp' );

TestHandle1 := ImageScrollBox.Graphic.BitmapHandle;
{TestHandle1 is non-zero at this point (but I can't vouch for it's validity)}

TestHandle2 := Image1.Picture.Bitmap.Handle;
{TestHandle2 is zero at this point}
