“““Simple?object?oriented?graphics?library??

The?library?is?designed?to?make?it?very?easy?for?novice?programmers?to
experiment?with?computer?graphics?in?an?object?oriented?fashion.?It?is
written?by?John?Zelle?for?use?with?the?book?“Python?Programming:?An
Introduction?to?Computer?Science“?（Franklin?Beedle?&?Associates）.

LICENSE:?This?is?open-source?software?released?under?the?terms?of?the

PLATFORMS:?The?package?is?a?wrapper?around?Tkinter?and?should?run?on
any?platform?where?Tkinter?is?available.

INSTALLATION:?Put?this?file?somewhere?where?Python?can?see?it.

OVERVIEW:?There?are?two?kinds?of?objects?in?the?library.?The?GraphWin
class?implements?a?window?where?drawing?can?be?done?and?various
Graphicsobjects?are?provided?that?can?be?drawn?into?a?GraphWin.?As?a
simple?example?here?is?a?complete?program?to?draw?a?circle?of?radius
10?centered?in?a?100x100?window:

--------------------------------------------------------------------
from?graphics?import?*

def?main（）:
????win?=?GraphWin（“My?Circle“?100?100）
????c?=?Circle（Point（5050）?10）
????c.draw（win）
????win.getMouse（）?#?Pause?to?view?result
????win.close（）????#?Close?window?when?done

main（）
--------------------------------------------------------------------
GraphWin?objects?support?coordinate?transformation?through?the
setCoords?method?and?pointer-based?input?through?getMouse.

The?library?provides?the?following?graphical?objects:
????Point
????Line
????Circle
????Oval
????Rectangle
????Polygon
????Text
????Entry?（for?text-based?input）
????Image

Various?attributes?of?graphical?objects?can?be?set?such?as
outline-color?fill-color?and?line-width.?Graphical?objects?also
support?moving?and?hiding?for?animation?effects.

The?library?also?provides?a?very?simple?class?for?pixel-based?image
manipulation?Pixmap.?A?pixmap?can?be?loaded?from?a?file?and?displayed
using?an?Image?object.?Both?getPixel?and?setPixel?methods?are?provided
for?manipulating?the?image.
