ABSTRACT:
An information processing system having a character/pattern generator, in which outline information of a character/pattern expressed in a vector form is subjected to any of at least two sorts of coordinate transformations in accordance with an address allocation scheme of an output engine to-be-used. Besides, in generating and transferring character/pattern data of dot form for each of the outline information items of character/pattern parts in subregions into which a region of the character/pattern has been divided, the outline information of the character/pattern is divided in either of horizontal and vertical directions in data transfer unit in accordance with the address allocation scheme of the output engine to-be-used. Further, in transferring the character/pattern data of the dot form, addresses are updated in conformity with any of at least two address update schemes in accordance with the address allocation scheme of the output engine to-be-used.
