The memory includes a second memory area for storing a coordinate value of the graphic information, a first memory area for storing a geometric element defined by coordinate values and pointers indicating store areas storing the coordinate values, and a third memory area for storing a dimension value defined by a difference between two coordinate values and pointers indicating store areas storing the two coordinate values. When a coordinate value or a dimension value is changed, the graphic information processing apparatus changes also other necessary coordinate values or dimension values when such a change is executed. | |
