You are using ImageEnvert.
When you select an object, you copy and paste it,
The selected object is not copied. 
ImageEnvert's image is copied. 
I want to copy and paste the selected object to the clipboard.
The sauce I used is as follows.
procedure TfrmMain.imgViewKeyDown(Sender: TObject; var Key: Word; Shift: TShiftState);
begin
  if ((ssCtrl in Shift) and (key=ord('C'))) then begin
    imgView.ObjCopyToClipboard;
  end else if ((ssCtrl in Shift) and (key=ord('V'))) then begin
    imgView.UnSelAllObjects;
    imgView.ObjPasteFromClipboard(MousePos.X,MousePos.Y);
    imgView.Update;
  end;
End;
