HW1's sample result has been updated to include two more files from Task 2, Ducky-OD4-max256.ppm and Peppers-OD4-max256, which are using the following scaling formula before conducting ordered dithering:

I = (gray * 17) / 256;

The two original results, Ducky-OD4.ppm and Peppers-OD4.ppm, were using a slightly different scaling formula:

I = gray / 15;

You may use either formula in Task 2.
