No, I mean that like

Image1.Picture.Bitmap := SomeBitmap;

actually executes a


(see TPicture.SetGraphic called by TPicture.SetBitmap in picture.inc), so

SomeBitmap := Image1.Picture.BItmap;

should execute (with proper checks)


I speak about manipulating the Tpicture.Bitmap property itself, not the 
TBitmap properties, which would not be affected.
