If a matrix is displayed using image() and zoomed so that individual elements occupy more than one pixel on the screen, the elements either display completely or not at all. In particular, if the image is panned so that an element is partially on the screen and partially off, it doesn't display at all.

...then pan the image and observe how elements behave when cropped
