ABSTRACT:
A first picture composed of first pixels including a first number thereof arrayed in a first direction and individually having a first image data is multiplied to provide a second picture composed of second pixels including a second number thereof arrayed in a second direction and individually having a second image data. An association is effected between each of the first number of first pixels and a total of h of the second number of second pixels, where h is an integer digitally equivalent to a multiplication factor, before a total of h fractions of the first image data are distributed to the h second pixels, as the second image data thereof, so that a compositional context of a first image representable by the first image data is substantially left in a second image representable by the second image data, permitting a directionally deformable multiplication of a digital picture.
