Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device, and more particularly to a character processing device for underlining or shading a character when the character is displayed on a screen or output to a printer.

[0002]

2. Description of the Related Art Conventionally, in a character processing device for displaying a character on a screen or outputting it to a printer, the character is underlined so as to be emphasized or displayed. , It is performed by applying a shading modification.

FIG. 4 shows a typical modification method for characters in a conventional character processing apparatus.
(A) "Iue" in "Aiue Okaki" of Hiragana
4B shows a case of underline modification in which a wavy line pattern is applied as an underline 51, and FIG. 4B shows a simple diagonal line as a shaded area 52 in the “Iueoka” part of the “Aiueoka Kiku” of Katakana. It shows a case where the pattern is applied and is shaded.

In such modification, a character to start modification and a character to end modification on the edit screen are designated, and the specified modification pattern is applied to these characters and all characters between them. Is being done. Specifically, in the case of the underline modification described above, the wavy line pattern of the underline 51 is, as shown in FIG. 4A, the left end of the rectangle 53 representing the size of the underlined first character. By drawing a wavy line pattern repeatedly while keeping a distance corresponding to the length of the wavy line pattern itself as a base point, a continuous underline 51 is displayed as shown in a, b, c, and d. There is. In the case of the hatching modification, the hatched pattern of the hatching 52 is displayed from the upper left corner or the lower left corner of the rectangle 54 representing the size of the first character to be shaded, as shown in FIG. The slanted line pattern of the hanging 52 is repeatedly drawn while keeping the distance of the width and height of the pattern itself, so that continuous hatching is performed as shown in e, f, g, h, i, and j. It is being displayed as 52.

Further, in the above-mentioned conventional modification method, as shown in FIG. 5, in a character string having a wavy line pattern as an underline 51 on the editing screen, for example, a wavy line between "U" and "E" When inserting a character with a pattern, if the character string after the character string to be inserted is displayed, the hatched pattern is shifted from the character string before the insertion and a discontinuous portion (indicated by a point P) appears. Therefore, the length of the oblique line pattern of the underline 51 is made equal to the character pitch, or a method of displaying the underlined character string again from the beginning has been adopted. Also, in the case of the hatching modification, the hatched pattern of the hatching 52 may be shifted for the same reason as in the case of the underline modification, and the width of the hatched pattern may be the same as the character pitch, or A method of displaying the modified character string from the beginning again has been adopted.

[0006]

However, in the modification method in the character processing device, when the length of the wavy line pattern of the underline 51 and the width of the diagonal line pattern of the mesh 52 are made equal to the character pitch, the character pitch is changed. If the variable value is used, the pattern is changed, which causes a problem that extra processing time is required.

In the case where the modified character string is redisplayed from the beginning, the number of characters to be redisplayed becomes large, or the character string with the underline 51 and the shade 52 at the same time is redisplayed. There is a problem that it is necessary to specify the character position of the character that should start the, and for that reason it is necessary to sequentially judge what kind of decoration is applied to the character, and that processing takes a long time. .

The present invention has been made in view of the above problems, and when the character string is underlined or shaded, the patterns do not shift from each other without extra processing time. It is an object of the present invention to provide a character processing device that can realize a good working environment for the operator.

[0009]

To achieve the above object, a character processing apparatus according to the present invention displays a modification pattern storage means for storing a predetermined modification pattern for modifying a character and the modification pattern. Display means, a character position designating means for designating a display position of a character, and a decoration pattern display position designating means for designating a display position of the decoration pattern with respect to the display position of the character. There is.

Further, the modification pattern is characterized by including underline modification and / or halftone modification.

[0011]

According to the above construction, since the display position of the modification pattern such as the underline modification or the halftone modification is specified for the display position of the character, the modification pattern corresponding to the character position is always applied. Become.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a character processing device according to the present invention. A central processing unit (CPU) 5 is connected to a ROM 2 which is a read-only memory via a system bus 1. A RAM 3 which is a readable / writable memory and an external ROM 4 which is a read-only memory added to the outside are connected. The ROM 2 and the RAM 3 store a control program for executing the control of the character processing apparatus, and the ROM 2 and the RAM 3
3 and the external ROM 4 store predetermined character patterns and decoration patterns. Further, in the RAM 3, a register R1 in which character position data is written, a register R2 in which a character code is written, a register R3 in which character pattern data is written, a register R4 in which display start position data of a decoration pattern is written, and a display end position of a decoration pattern. The respective regions of the register R5 in which the data is written and the register R6 in which the data of the modification pattern are written are separately provided.

The CPU 5 also controls, via the system bus 1, a keyboard controller 6 for controlling the operation of the keyboard, a display controller 7 for controlling the display operation of various data, a peripheral device controller 8 for controlling the operation of peripheral devices, and processing. Printer 9 for printing out displayed characters
Are connected. Further, the keyboard controller 6 includes a keyboard 1 on which an operator performs desired input operations and the like.
0 is connected, a CRT 11 that displays various data on the screen is connected to the display controller 7, and a flexible disk 12 and a hard disk 13 can be attached to the peripheral device controller 8.

Therefore, the character processing device includes a character position designating means for designating the display position of the character and a modification pattern display position designating means for designating the display position of the modification pattern with respect to the display position of the character. Have, CPU5
2 sequentially reads the program according to the flowchart of FIG. 2 from the ROM 2 and the RAM 3 via the system bus 1 to perform the character modification processing. The operation will be described in detail below with reference to FIG.

First, in step S1, the leading character position of the character string to be displayed is written in the register R1. When a coordinate system that defines the X-axis in the horizontal direction and the Y-axis in the vertical direction with the upper left corner of the screen as the origin is used as the coordinate system for specifying the display position, and character display positions x and y are specified in that coordinate system Displays a character by aligning the upper left corner of the rectangle representing the size of the character with that position.

Next, in step S2, the leading character code of the character string to be displayed is written in the register R2. In this embodiment, a 2-byte code such as the JIS code is used as the character code, but the code is not limited to the JIS code as long as the code is defined so that one character can be specified.

Next, in step S3, the register R2
It is determined whether or not the content of is 0. Register R2
If the content is 0, it means that the character string to be displayed ends at that point, and the process proceeds to step S8. On the other hand, if the content of the register R2 is not "0", it means that there is a character to be displayed, and the process proceeds to step S4. Then, in step S4, the register R2
The character pattern specified by is written in the register R3. Next, in step S5, the character pattern written in the register R3 is displayed at the position designated by the register R1. Next, in step S6, the display position of the character to be displayed next in the register R1 is set, in step S7 the character code to be displayed next is written in the register R2, and the process returns to step S3 to repeat the process. Above, step S3
Through a series of repeated processing from step S7 to step S7,
Display a character string on the screen.

After the display of the series of character strings is completed, the process proceeds to step S8 to start the modification process. Step S8
Then, the position at which the underlined or shaded pattern starts is stored in the register R4 in the same coordinate system as that of the character pattern. Next, in step S9, the position at which the modification pattern of underline modification or halftone modification ends is stored in the register R5 in the same coordinate system as the above-described start position. FIG. 3 shows the relationship of these position designations. As shown in FIG. 3, the start position A of the modification pattern and the first character position S of the character string do not necessarily have to match. Further, the position A is just the start position of the pattern, and the actual modification is as shown in FIG.
As shown in, it is performed from the beginning position S of the character string,
No modification is made between position A and position S. In addition, position A
May be fixed to the left end of the character display area on the screen, or may be the head of each character string, and is not limited as long as the position is predetermined.

Next, in step S10, an underlined or shaded modification pattern is written in the register R6. Next, in step S11, the positional relationship between the register R4 and the register R5 is checked, and if R4 <R5 is satisfied, that is, if the modification pattern has not reached the end position, the process proceeds to step S12 to continue the processing. , R4 <R5
If is not satisfied, it is considered that the modification processing has already been completed, and the processing ends.

In step S12, the modification pattern in the register R6 is displayed at the position indicated by the register R4,
In step S13, the position of the register R4 is added by the width of the modification pattern of the register R6, and the process proceeds to step S11 to repeat the process. By this series of processing, the modification patterns shown at the positions B, C, D, and E in FIG. 3 are displayed, the patterns are repeatedly displayed up to the end position Z, and finally the continuous modification patterns are applied to the character string. . Further, by always keeping the start position A constant irrespective of the display position S of the character string, the continuity of the modification pattern applied to the character string can be maintained.

It is needless to say that the present invention is not limited to the above-mentioned embodiment and can be modified within the scope not departing from the gist. Further, although FIG. 3 shows the case of underline decoration, it goes without saying that in the case of halftone decoration, the same processing as underlining is performed by repeatedly displaying halftone patterns.

Further, in the process of inserting the same modified character string "insert" between "i" and "u" of the character string of FIG.
As shown in FIG. 6, at the start position A of the modification pattern, the same start position A as when the original modified character string was drawn is specified, and at the beginning position S of the character string, the character string to be inserted is inserted. Specify the position, specify the ending position of the decoration of the character string containing the character string to be inserted in the end position Z, and redraw all the character strings after the insertion character string, while maintaining the continuation of the decoration pattern. , You can insert the required string.

Further, FIG. 6 shows the case of underline decoration, but it goes without saying that the same applies to the case of halftone decoration.

[0025]

As described in detail above, according to the present invention, it is possible to easily and quickly perform underline modification, halftone modification, etc., without requiring extra processing time, regardless of the display position of a character string. It is possible to display a desired modification pattern while maintaining continuity, and it is possible to realize a good working environment for the operator.
