Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to character data processing devices, and in particular, to efficient modification of characters in document creation systems that display and print character data such as word processors. It relates to character data processing methods that can be used.

[Conventional technology]

In character data processing, when modifying characters in a string of two or more characters by enlarging, slanting, adding decorations, etc., the characters may be modified so that the effect of the modification changes in stages. be.

Although it was possible to modify the text of this food using conventional technology such as a word processor with a character modification function, there were some problems in terms of operability. This will be explained below using FIG. 2.

The screens of the 201ii display device are shown in FIGS. 2(a) to 2(e). Here, the character string 204 in FIG. 2(a) in which each character in the character string has the same size is replaced by the character string 204 in FIG. 2(c) in which the size of each character in the character string changes in stages.
Assume that you modify it like this. In the case of the conventional technology, modification operations were basically performed on a character-by-character basis. As a result, first, the size of the character 202 in one character string 204 is reduced to a character 205, and the state of the character string 205 is generated.

(Subsequently, by returning the same processing operation for the number of characters)
, a character string 206 can be obtained.

However, as mentioned above, the need to modify each character not only increases the number of operations depending on the number of characters, but also requires constant understanding of how much modification should be performed for each character. This placed a burden on the workers.

Furthermore, in the prior art, although it was possible to modify multiple characters at once, it was impossible to apply only the same modification content to all characters to be modified. Figure 2(a)
The character string 207 is an example in which the character size is reduced compared to the entire character string 202. Even if the conventional technology is used in this case, it will inevitably put a burden on the operator.

Further, in another conventional technique, the character string 209 in FIG. 2 (θ)
However, the deformation process could be performed by deforming the circumscribing frame 20B. However, in the case of another conventional technology, by treating the character string 209 as one figure, the circumscribing frame 209
13, and is different from the method using attribute information, which is the problem of the present invention, in terms of processing content. Further, other conventional techniques have functional limitations such as not being able to partially process character strings, and have problems with operability.

As described above, in the prior art, since there was no means for changing attribute information step by step, operability became a problem in character modification processing in which the modification effect changes step by step.

[Problem to be solved by the invention]

The purpose of the present invention is to improve this problem and improve the operability and expand the functions in the modification process of character data. The goal is to provide an efficient character data processing environment.

[Means for solving problems]

The above purpose is a means of calculating attribute information that gives a stepwise modification effect to the shape of each character to be modified, and a means to change the attribute information of character data to be modified based on the calculated attribute information. This can be achieved by adding a new feature to the conventional technology.

[Effect]

The means to calculate attribute information that gives a gradual modification effect to the shape of each character to be modified is to calculate the attribute information regarding the modification of two specified character data in a character string and the information between the two character data. Based on the number of character data, the attribute information required to give a gradual modification effect is calculated. The means for changing the attribute information of the character data to be modified based on the calculated attribute information is based on this calculation. Change information.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a flowchart showing an example of this method.

Moreover, FIGS. 3(a) to 3(θ) show the process progress displayed on the display device screen 301 when the process is performed according to the flowchart.

Hereinafter, unless otherwise specified, it is assumed that the operator's instructions, data, etc. are input using an input device such as a cheeboard. Here, as an example of processing, the character string 502 consisting of five characters in FIG. 3(a) is changed to the character string 3 in FIG.
A case will be described in which modification is performed such that the line width of the four characters from the beginning of the character string changes in stages, as in 03.

First, an example of a data structure that implements this method will be described. Character string data 401 includes an identification code C(n) 402 indicating the type of character. As character attribute information,
Character line width L(n) 402, character rotation angle R(n)
403, scaling factor 3 (
n) consists of 405. This data element is 40
A set of records 2 to 405 constitutes a record, and the character string data 401 includes records for the number of characters. (n) in the notation takes a natural number value and indicates which character data each data element is information about. 406 in Figure 4 indicates the record of the k-th character.7 Character string data 501 in Figure 5 is a representation of the character string 302 in Figure 5(a) using the data structure described above. .

In the first record 502 of the character string data 501, the identification code is the character "A", the line width of the character is "1", the rotation angle of the character is "0", and the scaling factor of the character is "2". This indicates that the modification has been applied. In this way, the character string data 501 is made up of a total of five records, with similar code codes for the remaining four characters.

Next, the flow of processing will be explained according to the flowchart of FIG.

First, regarding the two characters located at both ends of the range where a gradual modification effect is applied, the attribute information of the two characters is different, and the two characters exhibit different modification effects, which is a premise for applying this method. For example, in FIG. 3(b), the modification range is assumed to be from characters 305 to 304 on the display screen 601.
The line width of the characters is thicker. Regarding the strokes and line widths of characters, the two characters at both ends of the modification range have different modification effects.

However, if the premise state shown in FIG. 3(b) has not been generated, the premise state determination step 10 in FIG.
6, and the process of standard character modification step 101 is performed.

In the standard character modification step 101IC, one or both of the first character and the last character of mE to be modified in the character string is modified by the rounding that generates the prerequisite state. The modification process uses a character-by-character modification operation, which is a conventional technique.For example, it is assumed that each character in the character string 602 in FIG. 3(a) has the same modification effect. Here, in order to generate the state of the character 304 in FIG. 3 (13), only the fourth character of the character string 302 is modified and the line width of the character is made thicker. The character string data resulting from this processing is shown in FIG.
(4) 1 yuan with 1502 changed to “7” here is:
As shown in 503 in FIG. 5, it was "1".

After the above-mentioned prerequisite state is generated, the process proceeds to the following reference modification range step 102.

In the standard modification range designation step 102\C, the range to be modified within the character string is determined by designating the first and last characters of the range. Here, as shown in FIG. 3(C), the first character 505 and fourth character 506 of the character string are designated. The specified operation limits the range to be modified to the first four characters of the string.

Next, in a modification item designation step 103, one to be subjected to modification processing is selected from among the character modification items, in this case, the character line width per rotation angle scaling factor. In the example shown in FIG. 3, the item line width of characters is specified. By this specifying operation, the character line width L(n
) will be processed only.

Next, in attribute information calculation step 104, attribute information for intermediate characters within the modification range excluding the first and last characters is calculated. In the case of the third factor, the changes in the line width of the first character 305 and the last character 306 in the modified range are divided into four stages by calculation, and the line width of the middle character in that case is calculated. Find the attribute information to be given. The following calculation formula is used for the calculation process.

d= (Z(7)-Z(X))/(7-X)...(A
)z(n)=Z(x)+(n-x)xa m (B)
In the above equation, each variable indicates the following contents.

X: Order of the first character of the modification range from the beginning of the string y: Order of the last character of the modification range from the beginning of the string n: Order of the characters whose attribute information is to be modified due to modification, from the beginning of the string Z(k): Attribute information of the th character from the beginning of the character string d: Variable for temporary storage of calculation results A case will be described in which the above calculation formula is applied to the character string data 601JIC in FIG. 6. In this case, equation (A) becomes as follows.

a=(L (a)-L, (1))/(4-1)=(7-
1)/l = 2... (C) Using the result of the above 0 (C) formula, the (B) formula becomes as follows.

L(n)=L(1)+(n-1)x2 =1+(n-1)X2...(D) Use equation (D) to find n! +1 to y-IKQ to find L(n). In this example, since n=2.3, the following attribute information can be found.

L(2)=3, L(3)=5...(
E) As described above, the attribute information calculation step 104 calculates the attribute information of the character to be modified.

Finally, in attribute information setting step 105, based on the attribute information obtained in step 104, the attribute information of the characters whose attribute information should be changed and the characters between the beginning and the end of the block modification range are changed. In the example of FIG. 6(C), the character string 503 of FIG. 5(d) is obtained by changing the attribute information of characters 307 and 308 based on the nine attribute information determined by this calculation. Character string data 701 in FIG. 7 shows the status of the processing result. Based on the result of equation (B) obtained in the previous step 104), the line width 702 of the second character is set to 1.
3", and the line width 703 of the third character is set to "5".

By the way, in the example of this explanation, based on the change in the attribute information of the range specified in the reference modification range designation step 102, modification processing is performed only on characters in the same range. Similarly, it is also possible to perform modification processing on the entire character string based on the change in attribute information in the range specified in step 102. That is, it can be realized by applying the processing of the attribute information calculation step 104 and the attribute information setting step 105 of the chart 70 in FIG. 1 to all characters in the character string. This will be explained below using the same example as above. formula(
Based on D), if n is the entire string, then t) n=
2. 5. Perform calculations on 5.

In the case of z=1.4, the result of this calculation, which is already known and does not need to be determined, is as follows.

I, (2) = 3, L(s) = 5.

L(5)=9...(F) Based on the result of equation (F), this can be realized by changing the character string data in the same way as in the above example. An example of the displayed results is
The character string 3030 in FIG. 3(d) and the character string 309 in FIG. 5(e) are obtained.

Here, the character string 509 shows the result of applying the gradual change tendency of the line width of the - to four characters of the character string 503 up to the fifth character.

In addition, by repeatedly applying the process according to this method to the same character string, it is possible to apply this extreme modification to multiple locations, such as the character string 801 to the 0 character string 801.
In the case of , the character enlargement/reduction magnification is modified in two places: the range of - to third characters and the range of fourth and fifth characters.

Furthermore, a character string 802 in FIG. 8 is the result of applying this method to the rotation angle of characters. For the data, attribute information was set so that the rotation angle of the characters increased by 45 degrees. This method can be effectively utilized when the effect of modification can be expressed quantitatively. Further, two or more types of modification effects can also be achieved by similar processing. The character string 805 is an example in which this method is applied to two types of attribute information items: character line width and character enlargement/reduction lJS magnification.

Next, the equipment configuration for realizing the present invention will be explained based on FIG. 9. The device configuration includes an input device 901 such as a keyboard for inputting character data etc. and operation instructions, a storage device 902 for storing character data etc., and a display device 90 such as a CRT display for displaying processing results of characters etc.
3 and a control device 904 that controls each part. The control device 904 includes a data input section 905 that receives character data input and operation instructions from the input device 901 or the storage device 902, an attribute calculation section 906 that calculates attribute information based on the method of the present invention, and an attribute calculation section. The data editing section 907 changes character data, etc. based on the processing results of the data editing section 906 and instructions from the data input section, and the data display section 908 displays the processing results and operation instructions of the data editing section 907 on a display device 905. Ru.

〔Effect of the invention〕

According to the present invention, it becomes possible to efficiently apply a stepwise modification effect to a character string. Furthermore, since the number of operations does not depend on the number of characters, fF is effective when performing this type of modification on a large number of characters.
