PURPOSE:To draw out a V groove as a smooth curved part at the time of drawing information output by processing connection dummy data for adding arc data corresponding to line width to end points of drawing data consisting of line elements with specific width after raster vector conversion. CONSTITUTION:This device is provided with an arithmetic means 3b which computes dummy circle data connecting end points of chart data which is made into vectors by a raster vector converting means 3a and a drawing control means 4c which drives a drawing means 7 according to the dummy circle data computed by said arithmetic means 3b and line drawing data. Then when the chart data which are converted into the vectors are outputted by the raster vector converting means 3a, end points of the chart data are connected arcuately under the control of the drawing control means 3c to draw the chart data. Consequently, the V groove of chart end points by the raster vector conversion is corrected arcuately and the end points of the chart such as chart such as a drawing are outputted smoothly at the time of chart output. |
