The DrawingPanel also supports getting and setting the RGB values of individual pixels, which makes it useful for learning about various looping and 2D list- processing algorithms. See PyDoc comments for individual functions below for more information. This library is based on Python's Tkinter GUI system. In particular, the drawing surface used by DrawingPanel is a Tkinter Canvas object, and many of our functions are wrappers around Tkinter Canvas functions. The DrawingPanel supports properties like color, background, width, height, etc. that can be accessed/modified either using traditional methods like get_color and set_background, or as properties named color or background. @author: Marty Stepp, Stanford University @author: Allison Obourn, University of Arizona @author: Stuart Reges, University of Washington @version: 2018/02/28 @copyright: Marty Stepp, Allison Obourn, Stuart Reges; for individual, educational, non-commercial, private use only; all other rights reserved. @see: http://effbot.org/tkinterbook/canvas.htm cCs|S(sn Converts between a single 0-based client coordinate and a 1-based Tkinter canvas coordinate.
