trying to make a valentine card? dont know how to do

the question or what I need is to make a valentine day card.

1. needs 4 types of graphics

2. greeting of "Happy Valentines!"

3. need one animation object moving, flickering/shivering , or color changinf background.

it needs to have sleep in it. (this is restating what the sheet says)

this is the graphics.py function

Learning objectives: Develop a Python program that uses the author's graphics package. Assignment: Write a program called greeting.py that displays a greeting card with Valentine theme. Use the author's graphics packages, graphics.py. Since everyone likes to design their own Valentine theme (heart, arrow, candy, etc.), we will leave it up to you what the details of the finished product should look like. To make the program more fun, there should be several elements you must include: 1. At least 4 different types of graphics 2. Greeting message like: "Happy Valentine!" 3. At least one animation as followings: a. Flickering/Shivering b. Object movement C. Color changing (either background of window or object's color) The loop that makes the movement (animation) may go too fast. To slow it down, use the sleep() function from the time library that is a part of Python. You will need to import the library into your code. The line time. sleep (0.1) will make the program pause for one tenth of a second, Make sure to provide users instructions on how to interact with your greeting card. For example, the message "Click anywhere to close" will accept a user's a mouse click and gracefully close the window. Adding sound effect is optional We will have a little in-class competition for the best Valentine greeting card among those who submit this assignment by due date, A Read aloud Computer Science 220 Policies for All Programming Assignments: Programming assignment grades will be based on elegance and usibility as well as correctness of result Collaboration policy for CSC 220 signments 1.

It was written by Jolin Zelle for use with the book "Python Programming An Introduction to Computer Science (Franklin, Beedle & Associates). The most recent version of the library can obtained at http://map Wartburg edu/relle/python. This document is a reference to the functionality provided In the library See the comments in the file for installation instructions There are two kinds of objects in the library The Graphwan class implements a window where drawing can be done, and various graphics objects 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 sain: vin - GraphWin("My Circle", 100, 100) - Circle(Point(50,50). 10) c.draw(in) vin.getMouno() # pause for click in window vin.clone) main() Grapain objects support coordinate transformation through the setCoorda nethod and input via monte or laryboard The library provides the following graphical objects Point, Line, Circle, Oval, Roctangle. Polygon, Text, Entry (for text-based input), and Image. Various attributes of graphical objects can be set such as outline.color, fill-color, and line width Graphical objects also support moving and andrawing for animation effects. 2 Graph Win Objects A GraphWin object represents a window on the screen where graphical images may be drawn. A program may define any number of GraphWins. A GraphiWin understands the following methods GraphWin(title, width, height) Constructs a new graphics window for drawing on the screen. The parameters are optional the default title is "Graphics Window," and the default size is 200 x 200 pixels Example: vin - GraphVin("Investnent Growth", 640, 480) plot(x, y, color) Drawn the pixel at (x,y) in the window. Color is optional block in the default Examples win.plot(35. 128, "blue") plotPixel(x, y, color) Drawn the pixel at the "raw"position (x,y) i noring any coordinate transformations set up by setCoordo.

Example: keyString win.checkey) Note: keystring may be the empty string net Coorde (x1, y11, rur, yur) Sets the coordinate system of the window. The lower left comer is (ally) so the upper-right corner is (rur, yur). Currently down objects are redrawn and sequent drawing is done with respect to the new coordinate system (except for plotPixel). Ecumple: vin.setCoordo co, 0, 200, 100) 3 Graphics Objects The module provides the following classes of drawable objects Point Line Circle Oval Rectangle, Polygon, and Text. All objects are initially created filled with a black outline.

Examples message.setTextColor("pink") 4 Entry Objects Objects of type Entry are displayed as text entry boxes that can be edited by the user of the program. Entry objects support the generic graphics methods move().draw(graphwin), undravo, setF111(color), and clone(). The Entry specific methods are given below. Entry(centerPoint, width) Constructs an Entry having the given center point and width. The width is specified in number of characters of text that can be displayed. Example: inputBox - Entry(Point(3,4), 5) get anchor () Returns a clone of the point where the entry box is centered Example: centerPoint - inputBox.getAnchor) getText Returns the string of text that is currently in the entry box.

Most platforms will support at least PPM and GIF images Display is done with an Tange object Images support the generic methods move (dx, dy), draw(graphin), undravo), and clone). Image-specific methods are given below Image CanchorPoint, filename) Constructs an image from contents of the given file, centered at the given anchor point. Can also be called with width and height parameters instead of filename. In this case, a blank (traruparent) image is created of the given width and height (in pixels) Example flower Image - Image(Point(100,100), "lover.gif"> Examples blank Image - Image (320, 240) getAnchor () Returns a clone of the point where the image is centered Excample: centerPoint - flower Image.getAnchor() gotWidth() Returns the width of the image. ExauplewidthInPixelu - flower Image.getWidth) gotHeight() Returns the height of the image. Frampler haghti Pivals - Anuar image gat. Haight getPixel(x, y) Returns a list Cred, green, blue) of the RGB values of the pixel at position (x,y). Each value in a number in the range 0 256 indicating the intensity of the corresponding RGB color. These numbers can be turned into a color string using the color rgb function (see next section) Note that piscel position is relative to the image itself, not the window where the image may be drawn. The upper-left corner of the image is always pixel (0,0) Example: red, green, blue - flover Image.getPixel(32,18) 6. Generating Colors setPixel(x, y, color) Sets the pixel at position tr.y) to the given color. Note: This is a slow operation Exampler Flower Image.setPixel(32, 18, "blue") nave(leane) Saves the image to u file. The type of the resulting file (eg. GIF PPS) determined by the extension on the filem Example: flowerinagesave"mypic.ppn) 6 Generating Colors Colors are indiented by strings. Most normal colores such as "red" "purple" "green" Keyan" etc. skllavalle. Many culon Wales, di 2-3 "red", which are increasingly darker shades of red. For a full list, look up X11 color names on the web. The graphics module also provides function for mixing your own colos numerically. The function color_rgb(red, green, blue) will return a string representing a color that is a mature of the interities of red, green and blue specified. These should be ints in the range 0-255. Thus color_rgb(255, 0, 0) is a bright red, while color.rgb(130, 0, 130) is a medium magenta Example: Circle.setFill(color.rgb(130, 0, 130)) 7 Controlling Display Updates (Advanced) Usually, the visual display of a Graphwin is updated whenever any graphics object's visible state is changed in some way. However, under some circumstances, for example when using the graphics library inside some interactive shells, it may be necessary to force the window to update in order for changes to be seen. The update() function is provided to do this update() Causes any pending graphics operations to be carried out and the results displayed For efficiency reasons, it is sometimes desirable to turn off the automatic updating of a window every time one of the objects changes. For example, in an animation, you might want to change the appearance of multiple objects before showing the next "frame of the animation. The Graphin constructor includes a special extra parameter called autoflush that controls this automatic up dating. By default, autoflush is on when a window is created. To turn it off, the autoflush parameter should be set to false, like this: wa - Graphwan("My Animat20n", 400, 400, autorius "False) Now changes to the objects in via will only be shown when the graphics system has some idle time or when the changes are forced by a call to update() The update() method also takes an optional parameter that specifies the maximum rate (per second) at which updates can happen. This is useful for controlling the speed of animations in a hardware-independent fashion. For example, placing the command update(30) at the bottom of a loop ensures that the loop will "spin" at most 30 times per second. The update command will inact an appropriate pause each time through to maintain a relatively constant rate. Of course, the rate throttling will only work when the body of the loop itself executes in less than 1/30th of second Example: 1000 frames at 30 frames per second 1. Controlling Deplay Updates (Advanced) vin - Graph Vin("Update Example", 320, 200, autof lush-Falne) for 1 in range(1000) craving commands for ith frame> update (30) TT
