Skeleton Program for Processing Images

The program below will work with this image, named "catGlasses.gif". It should be located in the same directory where the program is saved.

# imageProcessingSkel.py
# D. Thiebaut
# A skeleton program to start doing image processing
# in Python

from graphics import *

# image geometry
# 424x18
# make the window the same geometry
WIDTH  = 424
HEIGHT = 418
IMAGEFILENAME = "catGlasses.gif"

#----------------------------------------------------------------
def waitForClick( win, message ):
    """ waitForClick: stops the GUI and displays a message.  
    Returns when the user clicks the window. The message is erased."""

    # wait for user to click mouse to start
    startMsg = Text( Point( win.getWidth()/2, win.getHeight()-15 ), message )
    startMsg.draw( win )    # display message
    win.getMouse()          # wait
    startMsg.undraw()       # erase

def main():
    # open the window
    win = GraphWin( "Image Editor", WIDTH, HEIGHT )

    # open the cat image
    cat = Image( Point(WIDTH//2, HEIGHT//2), IMAGEFILENAME )
    cat.draw( win )

    waitForClick( win, "click to close" )

    win.close()

main()
