Question

PPM (Portable Pixmap) use three integers to represent a pixel – this means we can have images with RGB colors. You will create a Pixel class in C++ which has three attributes:

red: int
green: int
blue: int

You will create a default constructor that initializes those values to 255, and an overloaded constructor that takes user input to assign the values. The class will also have the following functions:

changeRGB (): Takes in three integers to update the red, green, and blue attributes. Returns nothing.
printRGB (): Takes in nothing. Prints the red, green, and blue attributes in order with a single space in-between each value. Returns nothing.

You will then recreate the art program from Assignment 5 with the following changes:

Instead of a 2D array of integers, you will create a 2D array of Pixel object. Don’t be scared! This is similar to creating a 2D array of strings.
You will prompt for three color values instead of one – red, green, and blue. These must be stored in a Pixel object in a cell in the 2D array.
You will create a PPM file instead of PGM file – the magic number is “P3” and there will be three integers printed per pixel instead of one.

Sample Output:
[Color Art Program]
Enter an image width: 3
Enter an image height: 4
Enter the fill color's red value: 21
Enter the fill color's green value: 25
Enter the fill color's blue value: 200
