Reference numeral 4 denotes an external main storage device including a hard disk.

FIG. 4 is an explanatory diagram showing ruled line management information managed in the RAM. As shown in FIG. 4, each ruled line has coordinates (x1, y1) of its starting point and coordinates (x2, y2) of its ending point.
Is managed (registered) on the RAM 6. Here, as shown in the figure, vertical ruled lines and horizontal ruled lines are managed separately.

FIG. 5 is an explanatory diagram showing two kinds of embodiments of the operation method for creating ruled lines. Referring to FIG. 5, an operation method for creating a ruled line according to the first embodiment will be described. In order to create a table with ruled lines on the document screen displayed on the display 7, the outline (frame) of the table is first created by designating the upper left coordinate and the lower right coordinate by the outline creation function. This rectangular area is divided by ruled lines to create a target table.

In order to draw a rule using the mouse 2, an arbitrary point 41 in the rectangular area closest to the start point of the rule to be created and the point on the rule to be created is first designated (pointed). .

Next, an arbitrary point 42 in the rectangular area closest to the end point of the ruled line to be created is pointed. The end point 42 to be pointed does not necessarily have to be on the ruled line to be created.

Therefore, by operating the mouse 2 as described above, a rectangle including the pointed start point and including the start point of the ruled line to be created and a rectangle including the end point of the ruled line to be created are divided. You can draw horizontal horizontal rules or vertical vertical rules. Therefore, the first embodiment of FIG. 4 shows an example in which the horizontal ruled line 43 is drawn.

Here, the pointed start point and the pointed end point are in the order of the points, not the positional relationship of the points. Further, an embodiment in which the ruled line to be created is a ruled line including the pointed end point instead of the pointed start point can be considered.

FIGS. 6 and 7 are flowcharts showing a ruled line creation process according to the first embodiment of the present invention. The flow of the ruled line creation processing according to the first embodiment shown in FIG. 5 will be described with reference to FIGS. Step 51: When the start point is pointed on the screen by the mouse 2, the designated start point coordinates are captured by the position coordinate detection processing of the CPU 3.

Step 52: Similarly, when the end point is pointed by the mouse 2, the designated end point coordinates are
Is acquired by the process of detecting the position coordinates.

Step 53: It is determined from the coordinates of the start point and the coordinates of the end point whether to create a vertical ruled line or a horizontal ruled line. This determination is made assuming that the coordinates of the pointed start and end points are (px1, py1) and (px2, py2), respectively.
By comparing px1-px2 | with | py1-py2 |, it is determined that a horizontal ruled line is created if the X coordinate distance is greater than the Y coordinate distance, and a vertical ruled line is created otherwise.

Step 54: When it is determined that a horizontal ruled line is to be created, the process proceeds to step 55, where the case where px1 <px2 will be described.

Step 55: The CPU 3 searches for a neighboring vertical ruled line by searching the position coordinates managed on the RAM 6 from among the ruled lines surrounding the pointed start point by the neighboring ruled line search processing. More specifically, the starting point (x1,
y1), end points (x2, y2) at both ends, and y1
Of the vertical ruled lines satisfying <py1 <y2 and x1 (= x2) <px1, the vertical ruled line that minimizes | px1-x1 | is the desired vertical ruled line.

Step 56: Similarly, by searching for a neighboring ruled line, a vertical ruled line existing outside of the ruled line surrounding the pointed end point is retrieved by searching the position coordinates managed by the RAM 6. More specifically, the starting point (x3, y
3) having end points (x4, y4) at both ends and y2 <
Among the vertical ruled lines satisfying py2 <y4 and px2 <x3 (= x4), the vertical ruled line that minimizes | x3-px2 | is the desired vertical ruled line.

Step 57: Next, a perpendicular line (horizontal rule line) including the pointed start point and intersecting with the obtained two vertical rule lines is obtained. In detail, assuming that the coordinates of both ends of the vertical ruled line obtained above are a start point (x1, y1), an end point (x2, y2), a start point (x3, y3), and an end point (x4, y4), The position coordinates are the starting point (x1, py
1) It becomes the end point (x3, py1) and is replaced by the process of position coordinate replacement.

Step 58: Further, it is checked whether or not the perpendicular (horizontal rule) intersects the vertical rule on the end point side. Specifically, y3 (= y1) <py1 <y4 may be satisfied.
If not, an error occurs and the user is notified that a ruled line cannot be drawn at that location, and the process ends.

Step 59: The starting point (x1, py1) and the ending point (x3, py1) of the obtained perpendicular line (horizontal ruled line) are displayed by ruled line display processing. By the processing of steps 55 to 59, a predetermined horizontal ruled line can be drawn.

In the case of a vertical ruled line by the processing of steps 60 to 64, a predetermined vertical ruled line can be drawn in the same manner.

Referring to FIG. 5, a description will be given of a method of operating ruled line creation according to the second embodiment. In order to create a table on the document screen displayed on the display 7 with ruled lines, the outline of the table is first created by designating the upper left coordinates and the lower right coordinates by the outline creation function. This rectangular area is divided by ruled lines to create a target table.

In order to draw a ruled line using the mouse 2, an arbitrary point 44 in the rectangular area closest to the starting point of the ruled line to be created and the point on the ruled line to be created is first pointed. Next, in the direction of the end point of the ruled line to be created, an arbitrary point 45 near the intersection of the ruled line to be created with another ruled line is pointed. The end point 45 to be pointed need not necessarily be on the ruled line to be created, and may not be in a rectangular area including the end point of the ruled line to be created as in the first embodiment.

At this time, the coordinate of the pointed end point 45 is corrected to a horizontal coordinate 47 if it is close to the coordinate of the pointed start point, and to a vertical coordinate if it is close to the vertical. By doing so, the rectangle that includes the pointed starting point and that includes the starting point of the ruled line to be created and the horizontal horizontal ruled line or the vertical vertical ruled line that separates the rectangle near the end point of the ruled line to be created Can be pulled. In the second embodiment shown in FIG. 5, a horizontal ruled line 46 is drawn.

Here, the pointed start point and the pointed end point are in the order of the points, not the positional relationship of the points.

FIGS. 8 and 9 are flowcharts showing ruled line creation processing according to the second embodiment of the present invention. Using FIGS. 8 and 9,
The flow of the ruled line creation processing according to the second embodiment illustrated in FIG. 5 will be described. Step 71: When the start point is pointed on the screen by the mouse 2, the start point coordinates are captured by the position coordinate detection processing of the CPU 3.

Step 72: Similarly, when the end point is pointed on the screen by the mouse 2, the coordinates of the end point are captured by the position coordinate detection processing of the CPU 3.

Step 73: It is determined from the coordinates of the start point and the coordinates of the end point whether to create a vertical ruled line or a horizontal ruled line. This determination is performed in the same manner as in the first embodiment. The coordinates of the pointed start point and end point are (px1, py1), (px
2, py2).

Step 74: If it is determined that a horizontal ruled line is to be created, the process proceeds to step 75, where the case where px1 <px2 will be described.

Step 75: The Y coordinate of the pointed end point is corrected to be equal to the Y coordinate of the start point by position coordinate correction processing. Therefore, the coordinates of the corrected end point are (px2, py1).

Step 76: By the neighborhood rule search process, a horizontal rule existing outside the ruled line surrounding the pointed start point is searched by searching the position coordinates managed in the RAM 6. More specifically, it has a start point (x1, y1) and an end point (x1, y2) at both ends, and has y1 <py1 <
Among the horizontal ruled lines satisfying y2 and x1 (= x2) <px1, the one that minimizes | px1-x1 | is the horizontal ruled line to be obtained.

Step 77: Similarly, by the process of searching for a neighboring rule, a horizontal rule existing outside the ruled line surrounding the corrected end point is retrieved by searching the position coordinates managed in the RAM 6. More specifically, the starting point (x3, y
3), having end points (x4, y4) at both ends and y3
(= Y1) <py1 <y4 and px1 <x3 (= x
Among the vertical ruled lines satisfying 4), the one in which | x3-px1 | is the minimum is the required vertical ruled line.

Step 78: Next, a perpendicular line (horizontal rule line) including the pointed starting point and intersecting with the obtained two vertical rule lines is obtained. More specifically, if the coordinates of both ends of the vertical ruled line obtained above are the starting point (x1, y1), the ending point (x2, y2), the starting point (x3, y3), and the ending point (x4, y4), the perpendicular ( The position coordinates of the horizontal ruled line are the starting point (x1,
py1) and the end point (x3, py1), and are replaced by position coordinate replacement processing. Here, since the end point has already been corrected, this perpendicular line intersects the vertical ruled line on the end point side, so that it is not necessary to perform processing to check whether it intersects with the vertical ruled line on the end point side. .

Step 79: The starting point (x1, py1) and the ending point (x3, py1) of the obtained perpendicular line (horizontal ruled line) are displayed by ruled line display processing. By the processing of steps 75 to 79, a predetermined horizontal ruled line can be drawn.

In the case of a vertical ruled line by the processing of steps 80 to 84, a predetermined vertical ruled line can be similarly drawn.

[0047]

According to the present invention, when a table is created within a frame of a ruled line created in advance, a target ruled line can be automatically and efficiently created without specifying coordinates of a start point and an end point accurately. Even when the ruled line is long, the distance for moving the cursor from the start point to the end point is shortened, and the operability is improved.
