Just to give everyone an example of changing a pixel, consider that you have a white background of 255 for red, 255 for green, and 255 for blue, and red circle, all having 255 for red, 0 for green, and 0 for blue. The size of an image is x:80, y:80.With that out of the way, let's focus on x:5, y:5 (in other words, 5 pixels to the right, 5 pixels down). The color of the pixel is red:255, green:255, blue:255. If you change this to rd:255, green:255, blue:254, the change is way too invisible to human eye, except if you have Paint Shop Pro (an image editor), you can track the pixels and notice the difference between the two image files, even though the images are the same except for slightly-changed pixel.I hope this can be of any help to you all... :)
