Page under construction!

Problem 1

You have been hired for the summer by a company that makes wrapping paper. The company has a Web form where customers can pick different colors, a general theme, and a message to print in the middle of the page. Then a Python program generates an image that is printed by a large format printer.

The image above shows one particular output, for somebody who has selected Cars as the theme, Yellow as the background, and "Happy Easter" as the message.

Your assignment

You must write a program that generates a sample output, with a predefined color, a predefined scheme, and a predefined message. Your program will NOT ask the user for any information.

Submission

You must submit 2 files:

• Your program, which should be called hw11a.py
• An image of the output generated by your program. It should be called sheet.png or sheet.jpg

Requirements

• Your program should print rows of cars. The color of the cars should be randomly generated.
• Your program uses the same car for each row (the image above shows an output of the optional and extra-credit program)
• You are free to pick the shape of your car. It must have at least 2 rectangles and at least two wheels. You pick the shape that you like.
• A given car can have differently colored rectangles, or the same color for all its rectangles. You decide.
• Cars are allowed to extend past the boundaries of the window.
• The message in the middle should appear inside a rectangle that hides the cars underneath it
• The message should be as centered in the rectangle as possible.
• The message should be large enough to be easily readable

Hints

• To set the color of the background, you can use the setBackground() canvas method:

win = GraphicsWindow(MAXWIDTH, MAXHEIGHT)
canvas = win.canvas()
    
canvas.setBackground( 0, 250, 250 )

• Printing text can be used using two other canvas methods: setTextFont() and drawText():

canvas.setTextFont( 'arial', 40, 'bold' )
canvas.drawText( 100, 100,  "CSC111 Homework 11" )

Submission

Remember that you must submit 2 files, the program and a screen capture of your window. The submission URL is http://cs.smith.edu/~thiebaut/111b/submit11.php

Optional and Extra-Credits: Problem 2 (20 points)

20 extra points = 10 points for program, 10 points for image
This second problem requires you to use two different types of cars. They should be different enough from each other to be easily distinguished from each other.

The program must generate rows of cars, alternating between the two types. The first row should have cars of Type 1, the second row cars of Type 2, and continuing alternating between the two.

You need to submit two files, a program called hw11b.py and a screen copy of your image, called hw11b.jpg or hw11b.png (all lower-case). Submit both to the same URL as above.
