Not really but you could use a PhotoImage like so:-


from Tkinter import *
root=Tk()
canvas=Canvas(root)
canvas.pack()

pxmap=PhotoImage(width=10, height=10)
for x in range(10):
    for y in range(10):
        pxmap.put('red', (x, y))

canvas.create_image(10, 10, image=pxmap)
root.mainloop()



This will create a red square at 10, 10 in the canvas.
