    This is the error i'm getting :

    >>> finalExam()
    getPixel(picture,x,y): x (= 300) is less than 0 or bigger than the width (= 299)
    The error was:
    Inappropriate argument value (of correct type).
    An error occurred attempting to pass an argument to a function.
    Please check line 26 of /Users/xorachelannx3/Desktop/CIS150-Programming/CIS 150 FINAL EXAM LAB/FinalExam_RGrass.py

    Not sure why this doesn't work, i've set my media path to the location of those images. anyone have any ideas on what is going wrong?

    Without knowing anything about makePicture let's guess

    canvasX = canvasX +2

    is a problem, you should go to half width and half height?

    You could kludge with
    try:
    except:
    statement.

    good luck!
