Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a method of displaying ruled lines in a display device such as a word processor, and particularly to a method for displaying ruled lines at corners such as branching points and bending points of ruled lines. Concerning rounding.

(b) Prior Art As disclosed in Japanese Patent Publication No. 61-41418, devices such as word processors have conventionally
Ruled lines are input and displayed, for example,
These ruled lines were used to display table frames and highlight titles. The displayed ruled line pattern was a linear pattern that was a combination of straight lines extending in the vertical direction and straight lines extending in the horizontal direction.

(c) Problems to be solved by the invention Conventionally, only linear patterns could be displayed as ruled line patterns, so at branch points and bending points, only angular T-shape or L-shape shapes could be displayed. , it was impossible to display a curved pattern.

(d) Means for solving the problem The present invention provides a display means, an instruction means for instructing the ruled line pattern displayed on the display means, an instruction means for instructing rounding processing, and a basic pattern of rounded ruled lines. and a storage means for storing, in accordance with the instruction means, determines a directional component of the ruled line pattern instructed by the instruction means, and when at least one of the upper and lower direction components and at least one of the left and right direction components exists, Based on the direction component of the specified ruled line pattern, a corresponding rounded basic ruled line pattern is read from the storage means, the pattern or a combined rounded ruled line pattern is outputted, and the outputted rounded ruled line pattern is converted into the specified rounded ruled line pattern. The ruled line pattern is displayed on the display device instead of the ruled line pattern.

(E) Effect In the present invention, when the indicating means instructs a cross-shaped or L-shaped angular ruled line pattern at the branching point and the bending point on the display means, and the instructing means instructs the rounding process, the indicated Since the ruled line pattern always has at least one of the upper and lower and at least one of the left and right direction components, the rounded ruled line pattern composed of the rounded basic ruled line pattern will be displayed in place of the specified ruled line pattern, and therefore, Rounding processing is performed at corners such as branching points and bending points.

(F) Embodiment FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, in which 1 is a keyboard, 2 is a key input control section, 3 is a cursor control section, and 4 indicates the direction of ruled lines to be created. 5 is a line type detection unit that detects the type of ruled line to be created; 6 is a ruled line code creation unit comprising a first ruled line code creation unit 7 and a second ruled line code creation unit 8; 9 is a ruled line code and a code memory for storing character codes; 10 is a ruled line pattern output unit that creates a ruled line pattern corresponding to the ruled line code read from the code memory 9; 11 is a video
A display control unit including RAM 12, 13
is a display, and 14 and 15 are OR logic sections.

The ruled line code stored in the code memory 9 is the second
As shown in the figure, it has an attribute section and a code section, and the code section stores code information NSEW indicating the vertical and horizontal direction components and line type of the ruled line pattern.
The attribute part contains border information CC indicating that it is a border,
In this configuration, rounding information P indicating whether or not rounding processing is to be performed is stored. The specific structure of the code information NSEW is the same as that of the above publication, and the rounding information P consists of 1 bit, and "1" indicates that rounding is "present".
"0" indicates "no rounding".

The ruled line pattern output unit 10 also includes a read determination unit 16 that reads and determines the contents of the code memory 9 addressed by the cursor control unit 3, a first ruled line pattern creation unit 17, and a second ruled line pattern creation unit 1.
8, and a rounding basic ruled line pattern storage section 19 in which basic patterns for constructing rounded ruled line patterns at branch points and bending points of ruled lines are written.
Eight types of rounding basic ruled line patterns are prepared for each type of line such as thin line, thick line, wavy line, etc. As an example, the eight types of rounding basic ruled line patterns A to H for thin lines are shown in Fig. 3. . AB, CD,
Each of the EF and GH patterns is a pattern corresponding to each direction component, up, down, left and right, and has two types of patterns for each direction component.

Therefore, as in the past, when an instruction is given to create a ruled line using the ruled line keys, numeric keypad, and cursor keys of the keyboard 1, the first ruled line code creation section 7 operates, and the ruled line direction and line type are specified, as well as the cursor in the code memory 9. A new ruled line code is created based on the ruled line code corresponding to the position and its surroundings, and the created ruled line code is written into the code memory 9.
In this case, the rounding information of the ruled line code stored in the coat memory 9 is all "0". The read determination unit 16 reads the ruled line code of the address specified by the cursor from the code memory 9, and when the rounding information is “0”, the ruled line pattern first generation unit 1
7 is activated, the first creation section 17 creates a ruled line pattern corresponding to the ruled line code, as in the conventional case. Then, the created ruled line pattern is
The created ruled line is written at the cursor position in the video RAM 12, and therefore, the created ruled line is displayed on the screen of the display 13.

The above description is about the ruled line display that has been commonly performed in the past, but in this embodiment, the following rounded ruled line display can also be executed.

That is, it is assumed that the creation of the ruled lines as described above has been completed and that the ruled lines as shown in FIG. 4A are already displayed on the screen of the display 13.

In this case, the ruled line pattern a at the bending point of the ruled line
When you specify with the cursor and operate the rounding command key on the keyboard 1, the second ruled line code creation section 8
In response to a rounding command, the ruled line code at the cursor position is read, and first, it is determined whether the rounding information is "1" or "0". Then, when the result of the judgment is "1", the rounding information P is reset to "0", but in this case, since it is "0", next, based on the code information NSEW, the rounding information P is reset to "0". , determines whether at least one of the top and bottom and at least one of the left and right exists, and if so, sets the rounding information P of this ruled line code to "1"; otherwise, leaves it as "0". Keep it. In the displayed ruled line patterns b and c, only one of the left and right or up and down direction components exists, but in the ruled line pattern a, both the downward and rightward components exist, so this ruled line code The rounding information P of is set to "1".

The read determination section 16 reads the ruled line code at the cursor position from the code memory 9, and when the rounding information P is "1", activates the second ruled line pattern creation section 18. In this second creation section 18, the corresponding rounded basic ruled line pattern is read out from the storage section 19 based on the code information NSEW of the input ruled line code, the read patterns are synthesized, and the current ruled line at the cursor position is A round ruled line pattern having the same directional component as pattern a is created. And the created rounded border pattern is the video
A round ruled line pattern is written to the cursor position in the RAM 12 and displayed at the cursor position on the display screen.

For example, in the case of ruled line pattern a, there is a downward component and a rightward component, both of which are thin lines, so the rounded basic ruled line patterns C and F shown in FIG. 3 are read out, these patterns are combined, and the A ruled line pattern α shown in FIG. 5 is created, and this pattern α is displayed in place of the ruled line pattern a, as shown in FIG. 4B. Furthermore, when the ruled line pattern d in FIG. Since there are downward and leftward components, the rounded basic ruled line patterns B, D, G, and H are combined to form the fifth
The rounded ruled line pattern β shown in the figure is created and displayed in place of the ruled line pattern d, as shown in FIG. 4B.

Furthermore, since the storage unit 19 has rounded basic ruled line patterns corresponding to each direction component as shown in FIG. 3 for each line type, for example, as in ruled line pattern e in FIG. If the line is thin and the rightward component is a dotted line, the second ruled line pattern creation unit 19 creates a rounded ruled line pattern γ shown in FIG. 5 that has the same direction component and the same line type for the same direction component. be done.

By the way, as described above, when the rounding information P of the ruled line code at the cursor position is already set to "1", the second ruled line code generation section 8 resets it to "0". If the rounding command key on the keyboard 1 is operated when the rounded ruled line pattern is already displayed as shown in FIG. The display returns to the ruled line pattern. If a key for commanding rounding processing and a key for issuing a command for undoing are provided separately, the determination of the rounding information P in the code memory 9 can be omitted, and the rounding information P can be set and reset unilaterally. You can also do that.

In this embodiment, as shown in FIG. 3, rounded basic ruled line patterns corresponding to each direction component are prepared. It is also possible to prepare a pattern, output the pattern as it is at the bending point, and synthesize the patterns at the branching point to output an appropriate rounded ruled line pattern.

(G) Effects of the Invention According to the present invention, it becomes possible to display the bending points and branching points of ruled lines with roundness through simple operations, allowing for more free-form framing and more prominent This makes it possible to display highlighted images, etc.
