Small black squares is places in the area +% of the box. The dimension of black square (length \deltablack) may be +% set by any means (\setlength). But it's reasonable to choose +% this dimension little greater than dimension of point of the +% output printer. By default it is equal to 0.3pt, that is suitable +% for the printer of 300 dpi. +% +% The degree of darkness is regulated by means of change the distance +% between small black squares. In this style squares are placed in the +% rectangular order - it's simpler, but result is not always very good. +% - See the style "shadbox1.sty". +% +% The retribution for driver-independence is: the less squares and +% nearer to each other, the greater the size of output DVI-file (and +% grows quickly).
