PURPOSE:To furthermore improve the degree of freedom of plotting expression by changing correlation between a plotting line and a position in the line width of the plotting line. CONSTITUTION:The coordinate value of start point data P0 of straight vector data V and the coordinate value of end point data P1 are stored in a working memory, the length L of the data V is calculated from these coordinate values, the coordinate values of respective vertexes Q0, Q1, Q2, Q3 of a rectangle to be a plotting area are calculated from line width data W and line width position data (t) stored in the working memory, and the rectangular plotting area is converted into plotting information based on respective coordinate values to display the plotting information on a display device. |
