WIDTH HEIGHT

255 IMAGE_DATA

The P2 tells image readers that it is a PGM file, and the 255 indicates the largest possible color value is 255.

You will first prompt the user to enter a width, height, and initial color value to fill the image. You should then create a 2D array with those dimensions and initialize each cell with that color value.

You will then use a loop to create a menu that repeatedly prompts the user to make one of the following choices:

Fill in a pixel with a new color

◦ Prompt the user to enter a row and column value and a new color value. If the array has that row and column index AND the color value is between 0 – 255, change the color at the index.

Otherwise, inform the user that it’s an invalid command.

Fill in a line with a new color

◦ Prompt the user to enter a starting row and column value, a new color value, a length value, and a direction (left, right, up, or down, case sensitive). If all those values are valid, fill in each index in the line with those values in the 2D array. If the row, column, color, and/or direction are not correct, inform the user that it’s an invalid command.

If the length is correct but would go outside the array (e.g. a length of 20 but the array only has 10 columns), fill in values up to the edge of the array and then stop. Do not cause an ArrayOutOfBounds error.

Print the PGM file

◦ This should print out the contents of a valid PGM image. You should be able to copy and paste the output into a file and load it in the same way as you did with the PBM file (shown below) – the only difference is that the extension should be .pgm.
