Abstract

Current formatters insert no extra space into the last line of a justified paragraph. This can result in a very dense last line as compared with the rest of the paragraph, which may not be visually pleasing. The present approach consists of increasing the interword spacing in the last line of a multi-line paragraph so that the density of this line matches the average density of the rest of the paragraph. This approach can be implemented in many different ways according to exactly what quantity is to be made uniform. Some of the possible quantities are: average size of interword gaps, the ratio of space to non-blank characters, or the average amount of extra space added for justification. The choice of which quantity to make uniform will make only minor differences in normal text.
