with TIETextLayer(ImageEnView.CurrentLayer) do
 begin
   txt := Text;
   if txt.IsEmpty then
     ShowMessage('Text is empty');
end;

Hi

That is correct. IsEmpty refers to the currently selected bitmap. Non-image layers do not have a valid bitmap, so return IsEmpty = true.

Use something like:

isEmpty := ( ImageEnView1.LayersCount <= 1 ) and ImageEnView1.IsEmpty;
