How to return height and width of a base 64 encoded graphic using tkinter

I am adding an image to my canvas background using a base 64 encoded graphic. My question is how to return the width and height of the encoded graphic image_png so I can set the width and height of the canvas to the same. 

import tkinter as tk    

image_png = """

NYa2q7mcirC5I5FofsK6hcHHgsSgx4a9yzXK0rrV19gRADs=
"""
master=tk.Tk()
master.geometry("100x100")

canvas=tk.Canvas(master)
canvas.grid()

photo=tk.PhotoImage(data=image_png)
canvas.create_image(0, 0, image=photo, anchor="nw")

master.mainloop()

I thought the solution could be something like the following (to make an example):

height, width = photo.height(), photo.width()
canvas.create_image(height = height, width = width, image=photo, anchor="nw")

Use width, height method of the PhotoImage:

...
photo = tk.PhotoImage(data=image_png)
print(photo.width())  # => 32
print(photo.height())  # => 32
...
