Properly speaking, the covered area should be shown scattered randomly about the pixel square. (b) A pixel from the image V, 30% covered. (c) The two pixels, drawn in a single square; the overlap area is 12% of the pixel. (d) The compositing result for U over V: All of the opaque part of U shows (covering 40% of the pixel), and the nonhidden opaque part of V shows (covering 18% of the pixel).

An n × k image is stored in the upper-left corner; to its right is an n × k/2 version of the image, then an n × k/4 version, etc.; below it is an n/2 × k image, then an n/4 × k image etc. The remaining quadrant is filled in with versions of the image that are condensed both in row size and column size. The recursion stops when the image is reduced to a single pixel. (b) A MIP map for a real image.
