This Python program is used to get the GIF (Graphic Interchange format) file and draw the smileys when the user clicking the GIF image.
Explanation of Solution
Program:
#import the header file
from graphics import *
#definition of "drawFace" method
def drawFace(center, size, window):
#get the "x" value
x1 = center.getX()
#get the "y" value
y1 = center.getY()
#get the "p1" value
p1 = Point(x1-(.7 * size), y1 - size)
#get the "p2" value
p2 = Point(x1+(.7 * size), y1 + size)
#call the "Oval" method
head = Oval(p1, p2)
#fill the color
head.setFill("white")
#call the "draw" method
head.draw(window)
#get the "lc" value
lc = Point(x1 - .2 * size, y1 + .6 * size)
#get the "rc" value
rc = Point(x1 + .2 * size, y1 + .6 * size)
#call the "Circle" method
leftEye = Circle(lc, .13 * size)
#fill the color
leftEye.setFill("white")
#call the "draw" method
leftEye.draw(window)
#call the "Circle" method
rightEye = Circle(rc, .13 * size)
#fill the color
rightEye.setFill("white")
#call the "draw" method
rightEye.draw(window)
#get the "m1" value
m1 = Point(x1 - .3 * size, y1 - .5 * size)
#get the "m2" value
m2 = Point(x1 + .3 * size, y1 - .25 * size)
#get the "m3" value
m3 = Point(x1 + .3 * size, y1 - .5 * size)
#call the "Rectangle" method
mouth = Rectangle(m1, m2)
#fill the color
mouth.setFill("white")
#call the "draw" method
mouth.draw(window)
#call the "Line" method
leftLip = Line(m1, Point(x1- .3 * size, y1 - .25 * size))
#get the center position
mLeftCent = leftLip.getCenter()
#get the "x" position
mLCx = mLeftCent.getX()
#get the "y" position
mLCy = mLeftCent.getY()
#call the "Point" method
mRightCent = Point(x1 + .3 * size, mLCy)
#call the "Line" method
lip = Line(mLeftCent, mRightCent)
#call the "draw" method
lip.draw(window)
#get the "x" positions
m1x = m1.getX()
m3x = m3.getX()
#get the "y" positions
m1y = m1.getY()
m2y = m2.getY()
#calculate the "t" value
t = m1x - m3x
#calculate the "t1" value
t1 = Point(m1x - (1/8 * t), m2y)
#call the "Rectangle" method
teeth = Rectangle(m1, t1)
#call the "draw" method
teeth.draw(window)
#iterate "i" until it reaches 7
for i in range (7):
#clone the face
t2 = teeth.clone()
#call the "move" method
t2.move(-i * (1/8 * t), 0)
#call the "draw" method
t2.draw(window)
#definition of main method
def main():
#get the input filename from the user
fname = input("Enter filename: ")
infile = Image(Point(10, 10), fname)
#get the width of the image
wWidth = infile.getWidth()
#get the height of the image
wHeight = infile.getHeight()
#set graph win name
window = GraphWin('Smile!', wWidth,wHeight)
#set the coords
window.setCoords(0, 0, 20, 20)
#draw a smiley
infile.draw(window)
#get how many faces the user wants to draw
n = eval(input("How many faces should we block? "))
#iterate "i" until it reaches "n"
for i in range(n):
#get the mouse action
point = window.getMouse()
#draw a face by calling the method "drawFace"
drawFace(point, 3, window)
#call the "main" method
main()
Output:
Enter filename: test_img.gif
How many faces should we block? 2
