Why is Photoimage put slow?

Question

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):
         


        

Answer 1

Try constructing a 2d array of colors and call put with that array as parameter.

Like this:

import tkinter as tk

img = tk.PhotoImage(file="myFile.gif")
# "#%02x%02x%02x" % (255,0,0) means 'red'
line = '{' + ' '.join(["#%02x%02x%02x" % (255,0,0)] * 1000) + '}'
img.put(' '.join([line] * 1000))
