Yes, you are right. Sorry, I should have checked it in source code before posting just from my memory. Usage of .tostring() was my first approach - I have replaced it later by .getdata() because of speed issues (we are speaking here about methods of the Image module available after installation of PIL). As I have experience with numarray only, I can't help here directly with a code example for Numeric.
