Here is how I've changed it, based on your message and the errors I received
while putting it together:
# load and display several images using Tkinter
# Tkinter reads only GIF and PGM/PPM images
# (for additional formats use Image, ImageTk from PIL)
from Tkinter import *
import time
root = Tk()
root.title("Click me!")
def next_image(event):
x0 = 0
y0 = 0
x1 = 1
y1 = 0
photoId = canvas1.create_image(x0, y0, image=photo)
step = 10.0
dur = .3
for i in range(1, int(step)+3):
xi = x0 + i*(x1-x0)/step
yi = y0 + i*(y1-y0)/step
canvas1.coords(photoId, xi, yi)
time.sleep(3)
canvas1.update_idletasks()
image = "DustY1.GIF"
photo = PhotoImage(file=image)
# make canvas the size of image1/photo1
width1 = photo.width()
height1 = photo.height()
canvas1 = Canvas(width=width1, height=height1)
canvas1.pack()
# display photo1, x, y is center (anchor=CENTER is default)
x = (width1)/2.0
y = (height1)/2.0
canvas1.create_image(x, y, image=photo)
canvas1.bind('<Button-1>', next_image) # bind left mouse click
root.mainloop()
its not really working at all now. I'm sure this is the right direction to
go, but I'm still not getting anywhere. I tried using the update, but it
didn't seem to do anything. At this point, I simply want movement from left
to right.
help... ?
