#X text 7 -643 When an image is represented as a grid every pixel value
will vary between 0 and 255 Color wrapping occurs when the result of
the operation on the pixel value would be higher than 255 Values above
255 are counted from 0 For example: if a pixel has a red value of 240
and 20 is added to it \, you get 5 instead of displaying 260 (240 +
20 - 255 = 5);
