摘要

A document generating apparatus and a document generating method capable of easily and effectively generating a document with a supplementary explanation in which a supplementary explanation character string is given in a ruby form in a character size which conforms to a character size of a document. The document generating apparatus (and method thereof) decides, for each line, a character size for characters included in each line in each character area, and corrects information on the character size based on the calculated value of the character size.
