This assignment is due Thursday night (4/24/14) at midnight. You can work in pair-programming mode on this homework.
Contents
Problem 1 (100 points)
- 100 points = 70 points for program, 30 points for image
- program: 70 = 20 points for documentation, 50 points for program structure, logic, and organization.
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, Blue as the background, and "Happy Easter" as the message.
Your assignment
You must demonstrate that you can have the programming job by writing 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 hw11a.png or hw11a.jpg
Requirements
- Your program should print rows of cars. The color of the cars should be randomly generated.
- Your program organizes the cars in rows, one above the other. The car may or may not align vertically (the image above shows them aligned vertically).
- You are free to design the shape of your car. It must have at least 2 rectangles and at least two wheels.
- A given car can have differently colored rectangles, or the same color for all its rectangles. Your design decision.
- 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.
- The actual text of the message is up to you. It should be at least 5 characters long.
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" )
- Do not hesitate to give your classes extra methods that can make your life easier in your main program. For example, I used a setRandomColor() method for my Car class. This way I can generate a black car, then ask it to pick its own random color:
# generate a black car by default c = Car( x, y, w, h, (0, 0, 0) ) # make it pick a random color for itself c.setRandomColor()
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 to be easily distinguished from one another.
The program must generate rows of cars, alternating between the two types of car. 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.
