Assignment $7$ B: Art Program! For our last assignment in CSE $1321$L$,$ we$$ll learn how to

create a basic image editing program. Most images are saved in binary format $$ this

means they are not human readable without special software like a hex editor.

However, a few are saved in ASCII$/$text mode, and you can read and edit them with just

a text editor. One such type is the black and white PBM images you created in a

previous assignment. For this one, we$$ll create the color Portable Pix Map image format.

You will create a program that generates the contents of a PPM file for a square image

$($we$$ll learn how to actually save a file in CSE $1322).$

You will create a Pixel class which has three attributes:

$$ red: int

$$ green: int

$$ blue: int

You will create a constructor that takes user input to assign the three RGB 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.

In a separate Assignment$7$B driver class, do the following:

$$ Prompt the user to enter a width and height value

$$ You will create a $2$D list of Pixel object based on the width and height. Don$$t be

scared! This is similar to creating a $2$D list of strings.

$$ Prompt the user for the initial fill color $$ this will be used to initialize all the Pixel

objects in the $2$D list to the same RGB

$$ Repeatedly prompt the user to make one of the following choices:

$$ Print the PPM file to the screen. Note that every valid PPM file starts with a

$$header$,$ which looks like this:

P$3$

$255$

The width and height values should be what the user entered, and the pixel

values should come from the $2$D list$$s objects.

$$ Change a pixel to a new color. Prompt the user for the pixel$$s coordinates and

the new RGB value, then update the Pixel object at that location in the list.

Refer to your prior work with the level map creator $$ the logic is similar.

$$ Change a line of pixels to a new color. Prompt the user for the starting

coordinates, the length, and the new RGB value. Then, update the colors of

all Pixel objects in that horizontal line. Refer to your prior work with the level

map creator $$ the logic is similar.

$$ Quit. Print the final image to the screen and stop the program.

If you$$re interested in actually seeing the image itself, check the appendix of this

assignment.
