This is a simple utility which displays and updates an image from the Python Image library.`from PIL import Image, ImageTk import Tkinter as tk from random import randint

class Chip8Screen(tk.Frame): def init(self, parent, resolution): tk.Frame.init(self, parent); self.parent = parent; #self.pack(); self.screen_data = Image.new('RGB', resolution); self.screen = ImageTk.PhotoImage(self.screen_data); self.label = tk.Label(parent, image=self.screen); self.label.grid(row=0, column=0); parent.bind('w', self.draw_random_pixel);

    def redraw_image(self):
            self.screen = ImageTk.PhotoImage(self.screen_data);
            self.label.configure(image=self.screen);

    def draw_random_pixel(self, event=None):
            print("Draw random pixel.");
            x = randint(0, 100);
            y = randint(0, 100);
            r = randint(0, 255);
            g = randint(0, 255);
            b = randint(0, 255);
            self.screen_data.putpixel((x, y), (r, g, b));
            self.redraw_image();

def main(): root = tk.Tk(); c8 = Chip8Screen(root, (320, 240)); root.mainloop();

if name=="main": main(); `
