Abstract

Text and graphics are justified along one physical dimension to a predetermined line of justification. A plurality of physical parameters are employed in the justification, each of the parameters is assigned a compression and an expansion adjustment ratio. Such ratios define the maximum adjustment range of each of the parameters. A priority of adjustment is assigned to each of the parameters such that one parameter being adjusted and capable of meeting justification needs is adjusted to the exclusion of all other possible parameter adjustments. In vertical justification of a plurality of columns, text distribution precedes the vertical adjustment. For such vertical justification, the priority of adjustment is based upon natural text/graphics breaks; top priority is use of lead outs, second is skips, third is spaces and last is textual adjustments. Justification is preferably proportional, i.e., the ratios are adjusted when the maximum permitted adjustment is not required for justification. For horizontal justification, similar ratio selections apply.
