Activity: Pictures 🎨

Complete the setup to install the cImage module and read some key differences based on the latest updates to the module.

Create a file called line.py and save it to your cs100/ch6 folder.

1. Copy the following code into your file:

   from image import *
      
   myWin = ImageWin(300, 300, "Class image")
      
   # create a new image which we modify
   img = EmptyImage(300,300)
      
   # diagonal pixels are colored black
   for i in range(300):
   
       # create a new pixel object with (red, green, blue) values
       blackPixel = Pixel(0,0,0)
   
       # note: setPixel(columnPosition, rowPosition, pixelObject)
       # set pixel at given columnPosition and rowPosition to be the color of pixelObject
       img.setPixel(i,i,blackPixel) 
          
   # YOUR CODE HERE (change image before it is displayed & saved)
      
   # displays the image
   img.draw(myWin)
      
   # saves image to the given file name
   img.save("classImg.gif")
      
   # when you click anywhere on the window, it closes
   myWin.exitOnClick()
   

2. Run the program. Inspect the code to understand what each line does.

3. Create a red square in the upper left corner which has width 100 pixels and height 100 pixels.

4. Add a rectangle in the upper right corner which has width 200 pixels and height 100 pixels, where each pixel is a random color.

When you are finished, your program should produce the following output:

If you finish early

1. Add more shapes to your new image. What else can you create? A triangle? Maybe a tree with leaves on it? A house? A smiley face?

2. Work on your final project with your group.
