[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a function (undo function) for restoring deleted drawing contents when drawing characters / figures.

[0002]

2. Description of the Related Art Most of the undo functions of conventional character / graphics drawing software have a function of simply memorizing and restoring the contents deleted one time ago. Corresponds to this.

As an example of such a one-time restoration, there is a technique described in Japanese Patent Application Laid-Open No. 3-224026.

In Japanese Patent Laid-Open No. 3-280162, a plurality of figures are displayed, and when the displayed figure is deleted by the user, the deleted figure is stored and restoration of the deleted figure is designated. Then, the stored deleted figure is displayed by a dotted line, and when the representative point of the figure displayed by the dotted line is picked by the user, the figure having the picked representative point is displayed (restored) by the solid line. The technology is described.

[0005]

According to most of the above-mentioned conventional techniques (including Japanese Patent Laid-Open No. 3-224026), it is possible to restore only the deleted contents of the past one time (the contents deleted immediately before).

According to the technique described in Japanese Patent Laid-Open No. 3-280162, the deleted contents can be restored a plurality of times. However, when the restoring process of the deleted contents is designated, the deleted figure is displayed as a dotted line and restored. This is a technology that restores the specified contents when the representative point of the desired figure is specified by the user. Therefore, when the deleted figures overlap or the deleted figures are complicated, they are displayed as dotted lines. There is a problem that it is difficult to determine the representative point of the figure and the usability is not good. In addition, in normal processing that does not specify the restoration processing, there is a problem that it is not possible to know whether or not there is deletion content that can be restored. Further, there is a problem that it cannot be applied when the deleted contents are characters.

It is an object of the present invention to provide a method for improving a function (undo function) of restoring deleted drawing contents when drawing a character / graphic.

More specifically, according to the present invention, deletion contents stored in a plurality of times are stored, icons corresponding to the deletion contents are displayed, and one of the displayed icons is designated by the user. And, by displaying (restoring) the deleted content corresponding to the specified icon, it is an object to provide an undo method having a function of tracing back the deleted content up to a plurality of times in the past and restoring it.

[0009]

Proceed to 17. In process 417, the stored 2
The character information surrounded by one character cursor position and the position information (deleted content information) are acquired and held. Then, the process ends (418).

FIG. 15 illustrates details of the restoration process (312 in FIG. 11). When the mouse button is pressed to start the process (501), first, the mouse position (position coordinate) is obtained (502). Next, from the icon information stored in the icon pattern storage unit corresponding to each displayed icon, the X and Y coordinates of the upper left corner of the icon (61 and 62 in FIG. 6) and the X and Y axis direction display of the icon are displayed. The width (63, 64) is obtained and the display range of the icon is calculated (503). After that, it is judged whether or not the calculated display range and the mouse position overlap (504), and when it is judged that they overlap, a delay is given for a predetermined time.
After that (505), it is determined whether the mouse button is released (506). When it is determined that the button has been released, after a certain time delay (507), it is determined again whether the button has been pressed (508). When it is determined that the button has been pressed, the icon overlapping the mouse cursor is specified by the above-described method (method of sequentially comparing the mouse position and the icon display range) (509),
A deletion content storage unit corresponding to the specified icon is specified (511). After that, the process exits the loop (512) and ends the process (513).

The icon moving process (FIG. 12) will be described in detail with reference to FIG. When the mouse button (21 in FIG. 1) is pressed to start the processing (601), the mouse position is first obtained (602). Next, from the icon pattern storage unit of each displayed icon, the X at the upper left corner of the icon,
The display range of the icon is calculated by obtaining the Y coordinate (61, 62 in FIG. 6) and the display width (63, 64) in the X and Y axis directions of the icon (603). Then, it is determined whether or not the calculated display range and the obtained mouse position overlap (604), and if they do overlap, after a certain time delay (605), it is determined whether or not the mouse button is released. (606). If it is determined that the player has not been released, a loop is entered (607). In the loop, the mouse position is obtained (609) and the icon is moved to the mouse position (61).
