This selected stroke will be edited in the subsequent processing, and this edit mode includes steps S206 to S209. First, in step S206, it is determined whether editing is completed. If the editing is completed, the process is ended, the edited character is stored in the storage device, and the edited character is targeted for the subsequent process for the character.

On the other hand, in step S206, if the editing is not completed, the process proceeds to step S207 to execute the stroke editing process. Here, the "stroke edit processing" is to perform processing such as (adding / decreasing / moving / changing attributes) the control points forming the stroke.

Of these, "to change the attribute" means that, for example, when there are three control points, the three points are interpolated by an arc, and whether the stroke for forming a curved line is a straight line or an arc. It means changing stroke attributes such as. Of course, it is not limited to a circular arc, and a spline curve or the like can be considered. Further, "add / reduce / move" means to delete all strokes / delete some strokes to reduce the whole stroke / change the positional relationship of strokes with other strokes to display the selected stroke. To change, etc. Here, FIG. 6 shows an example in which the attribute of one point in one character is changed to change the straight line into a curved line (arc).

When the stroke editing process in step S207 is completed, it is determined in step S208 whether the stroke has been changed. If the stroke has not been changed, the process returns to step S206. On the other hand, if the stroke has been changed, the process proceeds to step S209, and in step S209, the character screen is displayed again according to the result of the stroke change, and the change in stroke is reflected on the character screen. FIG. 7 shows a display example when the characters and strokes shown in FIG. 5 are edited. Then, the process returns to step S206.

As described above, by displaying the character screen and the stroke screen at the same time and displaying the change of the stroke immediately on the character screen so that the edited result can be easily visually confirmed, the character of the stroke change can be confirmed. It is possible to immediately know the influence on the, and the effect that the character editing becomes easy and reliable can be obtained. have.
