<p>PURPOSE:To obtain a better converted figure, by converting a figure to be enlarged or reduced in the order of the (x) direction and (Y) direction and reversely, and correcting both obtained figures on dot-correspondence basis. CONSTITUTION:The original figure 1 is processed in the order of 1st-axis (x axis) convertion 8 and correction 9, and 2nd-axis (Y axis) conversion 10 and correction 11, and the resulting figure is stored in a memory 12. Further, the original figure 1 is processed in the order of the Y-axis conversion 8 and correction 9, and x-axis conversion 10 and correction 11, and the obtained figure is stored in a memory 13. The figures stored in the memories 12 and 13 are compared mutually, dot to dot, by an AND logical part 14 and coincident dots are extracted to form the converted figure 7. It is corrected by dot-by-dot addition 19 or erasure 20 as shown by, for example, figure B. Thus, errors originating from half-adjustment are reduced to obtain the better converted figure.</p> |
