TOPIC 11 – GRAPHICS FUNCTIONS

LESSON WORK

QUESTION 1

Create a simple flag. While Canada’s flag would be awesome, perhaps a flag from France or Italy or any other country will take you a little less time.

Try to:

• Use up most of your window.
• Place the flag in (or near) the middle.
• Give your flag a reasonable width and height ratio. (Most flags aren’t square.)

QUESTION 2

Below you will find code that creates 15 different shapes and the window output of that code. You must associate each shape number with a letter. If you prefer, here is a link to a PDF document that you can print.

YOUR ANSWERS

Your answers should look like this:

1G

2A

3B

and so on…

THE CODE

public class Question2

{

public static void main (String[] args)

{

NOOPDraw.createWindow(500,400,"Guess which one!");

//SHAPE 1

NOOPDraw.drawRectangle(50,50,100,50);

//SHAPE 2

NOOPDraw.drawRectangle(200,200,50,100);

//SHAPE 3

NOOPDraw.drawClosedShape(200,120,220,150,260,160,290,120,260,90,230,100);

//SHAPE 4

NOOPDraw.drawLine(0,0,370,300);

//SHAPE 5

NOOPDraw.drawEllipse(50,300,100,50);

//SHAPE 6

NOOPDraw.drawClosedShape(25,200,35,250,45,200,35,150);

//SHAPE 7

NOOPDraw.drawRectangle(200,0,150,75);

//SHAPE 8

NOOPDraw.drawRectangle(400,100,75,75);

//SHAPE 9

NOOPDraw.drawTriangle(400,290,360,340,440,340);

//SHAPE 10

NOOPDraw.fillRectangle(350,175,25,25);

//SHAPE 11

NOOPDraw.drawClosedShape(280,300,280,350,300,350,300,300);

//SHAPE 12

NOOPDraw.drawRectangle(150,275,50,50);

//SHAPE 13

NOOPDraw.drawClosedShape(50,200,100,200,100,240,150,240,150,180,50,180);

//SHAPE 14

NOOPDraw.drawEllipse(300,0,75,75);

//SHAPE 15

NOOPDraw.drawTriangle(360,240,440,240,400,290);

}

THE OUTPUT

QUESTION 3

You have two options of for this question. Choose the one you prefer. Enjoy!

OPTION #1

Create a scene of your choice making use of as many functions as possible.

OPTION #2

Find a clipart image online and do the equivalent of tracing it. You can open the image in Paint or Paint.net. Inside, the x and y coordinates of the mouse are given at the bottom. So if you move the mouse at the ends of different lines, you can know the coordinates of that point. Use this information to recreate the image with NOOPDraw.

Note that curved segments (not full circles) can be replaced by many short straight segments.
