Abstract

PURPOSE:To prevent such a trouble where the characters are superposed on each other due to the change of character forms by shifting the character strings following an adjacent character according to the superposing extent if a specific character is superposed on its adjacent character due to the change of the character form. CONSTITUTION:A control part 1 is prepared together with a designating means 12 which designates a sentence containing the character forms to be changed. The part 1 changes a character designated by the means 12 into a desired form and detects the size of an area superposed on a character adjacent to a noticed character based on the form of the changed noticed character. Then the part 1 moves the character strings following a character adjacent to the noticed one based on the size of the detected area. Thus it is possible to automatically eliminate such an inconvenient case where the characters are superposed on each other due to the change of character forms.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device, and more particularly to a character processing device capable of displaying characters in a plurality of character forms.

[Prior Art] Today, in document processing devices such as word processors, it has become possible to edit and print out documents by transforming them into various forms of characters.

However, when a specific character in a collection is transformed into, for example, an italic character, there is a problem in that the character pattern overlaps with the adjacent character pattern.

Therefore, in order to avoid the characters from overlapping each other,
For example, if it is possible to insert a space between overlapping characters or change the inclination of italicized characters, it is necessary to reduce the inclination so that the characters do not overlap.

[Problem to be Solved by the Invention] However, if the former operation is performed, a problem arises in that character spacing becomes uneven, making it difficult to see.

In addition, if the latter is performed, that is, the transformation process is performed again to eliminate overlaps after character transformation, the intended character shape will not be obtained after all, and in some cases, the document creation efficiency will be reduced because the transformation process is performed many times. A problem arises in that the condition deteriorates significantly.

The present invention has been made in view of this problem, and an object thereof is to provide a character processing device that can automatically eliminate overlapping of characters due to changes in character form.

[Means for Solving the Problem] A character processing device of the present invention that solves this problem has the configuration shown below. That is, in a character processing device that displays and outputs characters in a plurality of character forms, there is provided a specifying means for specifying at least one sentence whose character form is to be changed, and a character specified by the specifying means in a desired character form. a changing means for changing the character; a detecting means for detecting, from the form of the character of interest changed by the changing means, the size of an area where the character of interest overlaps with a character adjacent to the character of interest; A moving means is provided for moving the character string based on the size of the area detected by the detecting means.

[Operation] In the configuration of the present invention, when the changing means changes the form of the character specified by the specifying means, the detecting means detects the size of the overlapping area with the adjacent character, and the size of the detected area is changed. This method moves adjacent character strings based on the

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Description of Device Configuration (FIG. 1)> FIG. 1 shows a block configuration diagram of a document processing device in this embodiment.

<Explanation of processing outline (FIGS. 2 to 4)> The processing outline of changing the character form in this embodiment in the above-described configuration will be described below.

Figure 2 shows VRAM13 (or IMEM14 when printing)
) is a conceptual diagram showing the expanded address position of the normal character pattern above.

In the figure, 21 is a typesetting (horizontal format) in which a character pattern of normal characters is developed within the grid.

When looking at the character development area 22, the lower left position 23 is the character pattern development start address.

Now, an outline of the processing when changing the character format in relation to the character development area and the development start address will be described below.

FIG. 3(a) shows the character development area before the character form is changed, and the start address B is shown. (0.0) as a reference, address B, ~B3 and address 82 ~ B5 are also 1. The development position and character form of character 2 are defined.

Now, as shown in FIG. 3(b), let us consider the case where character 1 is developed in the character development area 32 (the area surrounded by the solid line), that is, the case where character] is input as an italic character. At this time, if the character 2 to the right of the character 2 is inputted as a normal character pattern, the character pattern areas will overlap with each other as shown in the figure.

Therefore, in the embodiment, as shown in FIG. 3(c), when an italic character is specified, the development area of subsequent character strings is set horizontally so as not to overlap with the development area of the adjacent character. This is to shift the direction.

The problem here is how much the shift amount ΔX should be, and this is determined as follows.

First, by operating the bointing device 12,
Display the transformation definition screen as shown in Fig. 4, and set parameters for character shape transformation, such as the size parameter pt, which is the output size point, and the italic parameter (s x, s y) that indicates the angle of the italic character. . The set data is stored at the correct location in the RAM of the program memory 6.

Next, when a character string is input from the keyboard 11, the input character string is CR-coded according to the previously set character format.
Displayed on the T device 10.

At this time, the standard character development area 31 (Fig. 3(a)
)) is the expansion start address B. (0.0) as a reference, and is defined by addresses B1 to B3, and based on the set italic character parameters (sx, sy), addresses B1 and B3 are set in the character development area 32 in FIG. 3(b). The element addresses of B+' and B3° are changed.

However, the size of the characters can be obtained from the following equation (2).

s i z e = p t X O. 35]4Xmm
Unit resolution...■Next, the overlapping distance ΔX between the modified character 1 and the normal character 2 is expressed by the following formula (■).

ΔX=B3゜(X) B3(X)=BI゜(X)
B1(X)Bl'(X) -BO(X)=Bl°(X)... ■However, Bn(X) indicates the address (coordinate value) of the X component.

In this way, Δx:=B+'(x) is obtained from the formula (2), so the character 2 is expanded to a position shifted by ΔX in the right direction. This avoids the problem of overlapping due to character pattern deformation.

In addition, as shown in FIG. 3(d), characters 1. The same applies to the case where character 2 is transformed. In the case shown, the character 2
is in the opposite direction to character 1, that is, italic parameter (-sx'
．． sy).

Now, ΔX in this case can be calculated using the following formula (■).

△X= (B3' B3 )+ (83 B
3゜゜) = (B1゜-B+ ) + (B3 - B3゜) = (B1゜ - B.) + (B3 - B3゜゜) = B.゜＋(B3 B3")
...■In other words, move the expansion address of character 2 and the following normal character to the right △x (=B+゜ten(B3 11
33")), it becomes possible to obtain a result as shown in FIG. 3(e).

Incidentally, the modified character type setting in this embodiment is performed on a display screen as shown in FIG.

In the figure, 42 is a modified character parameter window,
It consists of a parameter setting area 43 and a candidate character group 45. This modified character parameter window 42 is displayed overlapping the document editing area 40 as shown in the figure by specifying the "emphasized Japanese text" icon in the menu area 41 with the cursor 46. Note that the document editing area 40 literally shows the document being edited.

In addition, the modified character parameter window 42 is to be used for the character where the document editing cursor (not shown) is located when ``emphasized Japanese text'' is selected, but it is necessary to specify a range to some extent. , character strings within that range may be transformed.

Now, when the modified character parameter window 42 is displayed, the operator selects a desired character from the candidate character group 45. The selected character is displayed next to the parameter setting window 43 as a character 44. In the embodiment, a state is shown in which the upper leftmost character of the candidate character group is selected.

Next, in order to transform the character, use the parameter setting area 4.
Set values related to transformation in the main items in 3. Characters based on this set value are reflected on the characters 44 in real time.

In this way, when the operator has finished processing related to the modified character, he gives a command to that effect to the device (actually, specifies an unillustrated icon with the cursor 46), and closes the modified character parameter window 42 (erases it from the screen).

When this closing process is performed, the character of interest is transformed based on its parameter value, but if an overlapping part occurs as a result, all characters located to the right of the character of interest are shifted by the distance of the overlap. That's why.

Description of Processing Procedure (FIG. 5)> The operation procedure of the MPU 2 will be explained according to the flowchart of FIG.

It is assumed that the character (or character string) to be transformed has already been specified prior to this process.

First, in step 81, it is determined whether or not a highlighted character instruction has been made. If there is no such instruction, the process advances to step S2, and processing based on the information instructed (or input) at that time is performed. Note that this process is not related to the gist of the present invention, so a description thereof will be omitted.

Now, when the emphasized character instruction is detected, the process proceeds to step S3, and character transformation information for the character (or character string) of interest is input. When the input of the modified character information is completed, the process proceeds to step S4, and the address of the character development area of the character of interest (or character string) is calculated based on the information. Then, from this calculation result, it is determined whether or not an overlapping portion occurs with respect to the character of interest.

If it is determined that an overlapping portion occurs, the process proceeds to step S6, and the overlapping distance is calculated. and,
In step S7, the character string located on the right side of the character (character string) of interest is shifted to the right by the overlapping distance. Then, in step S8, the expanded address of the shifted character string is obtained, and the process proceeds to step S9, where the layout and display is performed on the CRT device 10 based on the expanded address.

On the other hand, if it is determined that no character overlap occurs,
The process immediately proceeds to step S9.

With the above processing, when a character is transformed, it will not overlap with an adjacent character.

<Description of Other Embodiments (FIG. 6)> In the embodiments described above, italics are defined as the deformation information, and the avoidance of overlapping characters due to italics has been explained. However, it is not limited to this italic type. For example, assume that a shadow is defined as the deformation information. If the amount of shadow in this case is (x.y), then Fig. 6(a)
An overlap occurs between character 1 and character 2 as shown in . Therefore, character 1 defined by address B o "" B 3 is changed to address B as shown in FIG. 6(b). ．． Bl', B2゜, B
If the expanded address with shadow is defined as 3 degrees, the overlap between character 1 and character 2 can be avoided.

Incidentally, the shift amount ΔX in this case is used in the following equation (2).

△X: 82° (x) - B 2 (X) B3' (X) - 83 (X) - (4) However, B1° (x) =
B l (X)B1゜(Y) = B + (Y)
+ yB2゜(X,Y) =Bz(X.Y)+(
x. y)B3゜(X,Y) =B3(X,Y)+
Let it be (x, y).

In the embodiment, although characters (character strings) to be transformed are described as existing in an existing document, the present invention is not limited to this. For example, this may be the case where the character form for the character to be inputted from the keyboard is set. In other words, the present invention can be applied to a case where characters are input in italics and normal characters are input in the middle.

[Effects of the Invention] As explained above, according to the present invention, when the form of a specific character is changed so that it overlaps with an adjacent character, the character string after the adjacent character is changed based on the size of the overlap. By moving the characters, it is possible to avoid the problem of overlapping due to changes in character form.
