Why is Photoimage put slow?

When manipulating photoimage objects, with:

import tkinter as tk

img = tk.PhotoImage(file="myFile.gif")
for x in range(0,1000):
  for y in range(0,1000):
    img.put("{red}", (x, y))

the put operation takes a very long time. Is there a faster method of doing this?


Use a bounding box:

from Tkinter import *
root = Tk()
label = Label(root)
img = PhotoImage(width=300,height=300)
data = ("{red red red red blue blue blue blue}")
img.put(data, to=(20,20,280,280))
