Create an interactive programthat performs 3 image manipulations on an image [week9-photo.jpg](width = 600, height = 400, image credit: Ruca Souza).

The program must:

• Take user input (0/1/2/3/4) using a while loopto determine which manipulation options (2/3/4) they want to apply.
  • If the user enters 0, the program exits
  • if the user enters 1, show the original image*
  • if the user enters 2/3/4, perform the manipulation, then showthe result image*
  • if the user enters something other than the expected input(e.g., 5), display the message ?Sorry, I don?t understand 5? andtake the user input again.
• Define one function for each manipulationoption:
  • 2: invert(pixels) ? for each R/G/B value ineach pixel, ?flip? the value within the 0-255 range (e.g., 0becomes 255, 3 becomes 252, 127 becomes 128, 254 becomes 1, 255becomes 0). Hint: the original value and the ?flipped? value add upto 255.
  • 3: cover(pixels) ? change the bottom half ofthe image to black. If the image has an odd number of rows, changethe middle row as well.
  • 4: flipHorizontal(pixels) ? exchange eachpixel on the left with the corresponding pixel on the right withthe same distance to the middle of the image.
• Use a nested for loop in each function toapply changes to the pixels.
• Each function returns a 2D pixel array thatcould be used as parameters for saveImage and showImage

Remember to design your algorithm in English first, thentranslate it to Python code. Test as you go!

Notes

• For this exercise you will be using an image processing library(pygame) which is not natively available in IDLE. You can choose touse Repl.it (https://repl.it/ (Links to an external site.)) to dothis exercise, or use another Python code editor called Mu(https://codewith.mu/ (Links to an external site.)). Both have thelibrary built-in and is ready for use.
• We have provided you with 3 functions (getImage, saveImage, andshowImage) in a separate Python module file namedcmpt120imageWeek9.py. Use it to help you with this exercise.Do not change anything in this file.
• You must put all your function definitions for the manipulationoptions in another Python module file namedcmpt120imageManip.py. Each function takes in oneparameter returned by the getImage function (which is a 2D arraycontaining all the pixels). Refer to our lectures for details.This file should import the module:cmpt120imageWeek9.
• You must put your code for the interactive program (asking foruser input) in a Python file named main.py. Thisfile is what we called a ?driver file? that calls functions fromother modules including getImage, showImage, invert, cover,?etc
