getdata() Returns the content of this image as a sequence object containing pixel values. The sequence object is aligned so that the values for the first row immediately follow the values for the null string, etc.
Note that the sequence object returned by this method is an internal PIL datatype that only supports certain operations sequence. To convert it to a regular sequence (e.g. for printing) use list (im.getdata ()).
Syntax: Image.getdata (band = None)
band - What band to return. The default is to return all bands. To return a single band, pass in the index value (eg 0 to get the “R” band from an “RGB” image).
Returns type : A sequence-like object.
