Oscilloscope graph data cannot be converted to graphs

Question

I have successfully saved the oscilloscope graph data into the variable image_data, but I can't convert the data of this variable into PNG file, BMP file, and so on.

How should I write ....

import pyvisa
from PIL import Image


rm = pyvisa.ResourceManager()


scope = rm.open_resource('USB0::0x0957::0x1796::MY63080487::0::INSTR')


scope.write(':DISPlay:DATA? PNG, COLOR')


image_data = scope.read_raw()

print(image_data)
