Abstract

Text and graphics are recursively (includes iteratively) distributed among a set of balanceable columns capable of receiving text and graphics. The recursive distributions are at successively varying columnar depths (all columns in each recursion have a common target depth), upon completing each recursion, the difference between the resulting shortest and longest column depths is measured and compared with a standard. If the standard is met, the distribution is made final, otherwise subsequent recursions up to a predetermined number of recursions are employed. If the standard is not met, then after the predetermined number of recursions, the distribution yielding the least differential is selected as the final distribution. Vertical justification of the columns follows.
