ABSTRACT:
A character generation device that easily implements a multiple-font system without increasing the data amount is provided. Character data of a basic font is stored in a character data storage while paste component data is stored in a paste component data storage. A shape recognizer determines a length and an angle of a process-target element as well as an angle of a stroke to which the process-target element belongs, by referring to a font attribute storage based on a font code and character number specified from a keyboard. A paste component data modifier performs scaling up/down processing and rotation processing with the selected paste component data by referring to the font attribute storage. A data synthesizer generates character data that paste components, subjected to the scaling up/down process and the rotation process, are applied onto the process-target element. Thus, by applying paste components to the process-target element in the basic font, a multiple-font system can be implemented with small amounts of data.
