Why is Photoimage put slow?

Question

for x in range(0,1000):
  for y in range(0,1000):
         


        

Answer 1

Use a bounding box:

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