I have been using your library and am very pleased. I needed and so added the following code to EnRubber.pas:

procedure TRubberbandMouseHandler.SetSourceSelection(Rect: TRect );
var
XFactor, YFactor: double;
begin
// GetSelection(Rect);

XFactor := GetXFactor;
YFactor := GetYFactor;

Rect.Left := Round(Rect.Left / XFactor);
Rect.Right := Round(Rect.Right / XFactor);
Rect.Top := Round(Rect.Top / YFactor);
Rect.Bottom := Round(Rect.Bottom / YFactor);

SetSelection(Rect);
end;

This allowed me to set the selection coordinates relative to actual graphic size rather than the displayed size. Please feel free to include this code.
