     <p>In order to manipulate an image, we need to be able to access individual pixels.  This capability is provided by

     <p>Each Pixel object has three attributes: the red intensity, the green intensity, and the blue intensity.  A pixel provides three methods
                 that allow us to ask for the intensity values.  They are called <c>getRed</c>, <c>getGreen</c>, and <c>getBlue</c>.  In addition, we can ask a
                 pixel to change an intensity value using its <c>setRed</c>, <c>setGreen</c>, and <c>setBlue</c> methods.</p>
