title: How to control the size of a picture using tkinter?
body: <p>I want to control the size of the picture in <code>m_image</code> (say, I want it to be 420x380).<br>
  How do I do that?  </p>
  
  <pre><code>import tkinter as tk
  
  m_gui = tk.Tk()
  m_image = tk.PhotoImage(file = 'pic.gif')
  m_canvas = tk.Canvas(m_gui)
  m_canvas.create_image(0, 0, image = m_image)
  m_canvas.pack()
  
  m_gui.mainloop()
  </code></pre>
  
  <p>It would be great if you could also give an explanation about the first two parameters of the <code>create_image</code> func.</p>
  
  <p>Thank you</p>
