PURPOSE:To obtain the excellent computer graphic processing system which can generate a line segment attached a line type with the high degree of freedom at high speed. CONSTITUTION:A line type preparing function 1 is provided to prepare the line type, a recording means is provided with a line type table 2 to register the line type prepared by this line type preparing means 1, a real line data calculating function 3 is provided to calculate a coordinate value for generating the line segment completely with intergers without multiplication and division, and a line type reflecting function 4 is provided to generate the line segment while reflecting the line type, which is registered on the line type table 2, upon real line data calculated by the real line data calculating function 3. |
