Abstract

PROBLEM TO BE SOLVED: To set the restriction of character arranging position such as hanging arrangement by determining the arrangement of characters on each line based on character information held by a holding means. SOLUTION: With respect to a character string displayed on a CRT display device 1, a character string to execute hanging setting is range-designated by key-inputting from a keyboard 4 or through the use of a pointing device 5 such as a mouse, etc. The range designated state is reverse-displayed. Then with respect to this reverse displayed character string, information of 'hanging' is designated. Set information of 'hanging' is embedded in document data to be stored in RAM 8. Through the use of the 'position' of character information arranged with in a line expressing the base line of the line by 'baseline' in this way, a character shown by 'code' is displayed for coordinate values (position and baseline).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing method and apparatus, and more particularly to a document processing method and apparatus for suitably controlling character arrangement within a line.

[0002]

2. Description of the Related Art The procedure for arranging characters in a conventional document creating apparatus is as follows. That is, the length required to arrange the character data is calculated while arranging the character data, and the next character of the character code meaning a line feed or the length required to arrange the character is one line width. Leads to the next line from the character beyond.

In a recent text creating apparatus, specific character data such as punctuation marks and parentheses are registered in advance, and characters are arranged by the above method. As a result, specific character data (for example, punctuation marks and closing brackets) is placed at the beginning of a line. It is common to have a prohibition processing function that performs processing so as not to be arranged. In this prohibition processing example, when specific character data is to be arranged at the beginning of a line, the character arrangement is automatically adjusted by pushing the character immediately before the character data to the next line. FIG.
(1) of 4 is a diagram showing an example of such prohibition processing. In this way, by setting the specific character data to be subjected to the prohibition processing in advance, the creator of the text does not have to perform the prohibition processing each time by the editing operation, and the operability is improved.

Further, depending on the text editing apparatus, instead of performing the prohibition process on the specific data, a punctuation mark or a closing bracket is placed at a position exceeding the line length so that a specific character is not placed at the beginning of the line. Is being processed. Such processing is called hanging processing. FIG. 14B is a diagram showing an example of such a hanging process.

[0005]

However, in the conventional document processing apparatus that automatically performs the prohibition processing and the hanging processing, the hanging processing can be performed only on a predetermined character in the document creating apparatus or the document unit. There wasn't.
Therefore, it was not possible to hang arbitrary characters in the document.

15 (1) and 15 (2) are examples showing the above problems. In (1), the characters “.” And “)” that should be hung are lined up continuously. Here, when prohibition processing is set for “.” And “)”, even if the document creator tries to hang both of these two characters on the previous line, the conventional document creation apparatus automatically prohibits the prohibition. The processing is performed and the character arrangement is determined as shown in (1) of FIG.

In FIG. 15 (2), the audible sound is at the beginning of the second line. In some cases, it may be better to make dangling sounds and consonants. However, if these characters are not set as dangling characters, dangling processing is not performed in the conventional document creation device. That is, the hanging process cannot be executed for any character that is not set as a hanging character.

Therefore, in the conventional document creating apparatus, in order to make arbitrary character data appear to be hanging, it is desired to change the line length of only the line having a character to be hung or to hang it. For example, by making the entire line with character data prohibition of separation and making a line intentionally overflowing,
The document creator had to make various efforts, and the operation was troublesome.

The present invention has been made in view of the above problems, and it is a document that makes it possible to specify a part of character data arranged in an area and set a character arrangement position restriction such as a hanging arrangement. An object is to provide a processing method and apparatus.

[0010]

A document processing apparatus of the present invention for achieving the above object has the following configuration. That is, a document processing device that performs display based on document data, and a setting unit that specifies a desired character in the document data and sets restriction information that restricts the layout position of the specified character. For each character of the document data, a holding unit that holds character information including restriction information set by the setting unit, and a character arrangement in each line in the display of the document data are held by the holding unit. And a determining means for determining based on the character information.

Further, the document processing method of the present invention which achieves the above object comprises the following steps. That is, a document processing method for performing display based on document data, the setting step of designating a desired character in the document data and setting restriction information for restricting an arrangement position of the specified character. A holding step of holding character information including restriction information set by the setting step for each character of the document data; and displaying the document data,
And a determining step of determining the arrangement of characters in each line based on the character information held in the holding step.

<Procedure for Setting Hanging Characters by Specifying Character Range> A procedure for setting a character range and setting a hanging character as shown in FIG. 2 will be described. FIG.
FIG. 7 is a flowchart illustrating a procedure for designating a hanging character according to this embodiment. It should be noted that this flowchart is activated when the range is specified as shown in FIG. 2 and an instruction operation is performed to set a hanging character.

First, the character offset 3e (offset) of the first character of the designated range (the highlighted range in FIG. 2) is obtained in step S16.1, and step S1
Substitute the variable count in 6.2. Next, in step S16.3, the character offset 3e (offset) of the last character in the designated range is acquired.

In steps S16.4 to S16.6, the hanging flag (burasagari) in the character information of each character from the first character to the last character in the designated range is set to "1".
Set to. First, in step S16.4, it is determined whether the variable count is larger than the offset of the last character. If the variable count has not reached the offset of the last character, the process proceeds to step S16.5 and the offset indicated by count is offset.
Set burasagari of character information having t value to "1". Then, in step S16.6, count is set to 1
Is added, and the process returns to step S16.4.

As described above, by setting burasagari in steps S16.5 and S16.6 until the count value exceeds the offset value of the last character in step S16.4, all the values within the specified range are set. Burasagari in the character information of the character is set to 1. In the in-line typesetting process that follows, the bura set in this way
Refer to sagari to determine the characters to put in the line.

<In-line typesetting process> Next, the in-line typesetting process according to this embodiment will be described. First, an outline of the method of character arrangement within a line will be described. FIG. 5 is a flow chart showing a procedure for arranging characters in a line according to this embodiment.

First, in step S7.1, row initialization processing is performed. Details of the line initialization process will be described later with reference to FIG. Next, in step S7.2, characters are arranged in a line. Here, in consideration of the hanging process, as many characters as possible can be driven in and characters that can be arranged in the line are determined. Details of the processing in step S7.2 will be described later with reference to FIG. Then, in step S7.3, an in-line character arrangement position determination process for the line is performed. Details of this process are shown in FIG.
Will be described later.

Next, the details of the process of arranging characters in a line according to the present embodiment will be described by describing the processes of the above steps in more detail.

FIG. 6 is a flow chart showing the procedure of the row initialization processing according to this embodiment. First, step S
At 8.1, the number of characters in line 2c (word_count) is initialized. The in-line character count 2c is information regarding the number of characters in a line in which character layout is to be performed, and the initial value is 0.

In step S8.2, the beginning coordinate 2a (kumi
sitan) and line end coordinates 2b (kumisyuuttan) are defined.
Generally, the coordinate value will be inherited from the immediately preceding line. Of course, it is also possible to change the line start coordinates 2a and the line end coordinates 2b on a line-by-line basis, and the respective values will change depending on the situation.

In step S8.3, the baseline position 2f (baseline) of the line and the character offset 3 of the first character in the line
Define e (offset). baseline is the baseline of the previous line
It is + row pitch. 1 if the beginning of the offset document, otherwise offset + 1 of the last character of the previous line
It is.

In step S8.4, 0 is substituted for the length length of the character arranged in the line. Subsequent Step S8.5
Substitute 0 for the number of characters overflow to be hung in the line. Further, in step S8.5, 0 is substituted for the number of characters overflow for which hanging processing is performed within the line.

The above is the line initialization process. Next, the in-line character arrangement process (step S7.2) will be described. FIG. 7 is a flow chart showing the procedure of in-line character arrangement processing according to this embodiment.

In step S9.1, an area for setting character information is secured. Here, the character information is the information shown in FIG. In step S9.2, various character information is set. The following information is set here. That is: ・ offset ・ code of character specified by offset ・ word_size of character specified by code ・ gap of character specified by offset, code ・ hanging flag (burasagari). For burasagari, "1" is set for the character for which "hanging" is set, and "0" is set otherwise.

Next, in step S9.3, the length of the character string at the time when the characters set in step S9.2 are arranged in the line is calculated. The length of the string at this point
The length has a value represented by length = length + word_size + gap (1).

In step S9.4, it is determined whether a character can still be arranged in the line. The determination is sequentially performed under the following three conditions. That is, 1. If the currently placed character is a line feed code, no more characters are placed in the line. If length <kumisyuutan-kumisitan, characters can be placed in a line. Even if kumisyuutan-kumisitan <length, if the burasagari = 1 for the character currently being processed, the character can be arranged.

If it is determined in step S9.4 that no more characters can be placed in the line due to the above three conditions, this process ends.

On the other hand, if it is determined by the above three conditions that the character can still be arranged in the line, step S
Go to 9.5 and place the next character on the line
Step f9 by advancing fset by 1 and incrementing word_count by 1.
It returns to the process of 1.

In-line character arrangement processing can be performed by advancing the above processing until characters cannot be arranged in the line.

Next, the character arrangement position determination processing executed in step S7.3 will be described. FIG. 8 is a flowchart showing the procedure of the character arrangement position determination processing according to this embodiment.

By the procedure described in FIG. 7, the character string to be arranged in one line and the length length of the character string are obtained.
In step S10.1, the margin distance is calculated by subtracting the length (length) required for character arrangement from the line length (difference between line start coordinates and line end coordinates). Therefore, this distance
Can be calculated by distance = kumisyuutan-kumisitan-length (2).

Next, in step S10.2., It is determined whether or not there is a blank space. This determination is made based on whether distance <0 (3) holds. If the above equation (3) is established, it means that the length required for character arrangement is longer than the line length, so it is considered that there is a "hanging" character,
The procedure moves to the dangling arrangement process in step S10.6. The details of this hanging process will be described later with reference to FIG.

On the other hand, if the expression (3) is not satisfied in step S10.2., The procedure goes to the determination in step S10.3. In step S10.3, it is determined whether the line currently being processed is a natural line break. If there is no natural line feed, natural placement processing is performed in step S10.5. The natural arrangement processing will be described later with reference to the flowchart of FIG.

Furthermore, if it is determined in step S10.3 that there is a natural line break, step S10.4.
Proceed to and perform the uniform placement process. The uniform placement process will be described later with reference to the flowchart of step 11.
Here, the natural line feed is not a line feed based on a line feed code, but a case where characters are not lined up in one line and line feed is performed naturally.

The above is the outline of the character arrangement position determination processing. Next, the hanging placement process of step S10.6, the natural placement process of S10.5, and the uniform placement process of S10.4 will be described.

First, the hanging character arrangement processing will be described. FIG. 9 is a flowchart showing the procedure of the hanging placement process according to this embodiment.

First, in step S11.1, the number of hanging characters (overflow) in the line is calculated.
This processing will be described later with reference to FIG. Next, in step S11.2, the characters not related to hanging in the line are evenly arranged by the end of the line. Details of this uniform placement processing will be described later with reference to FIG. And
In step S11.3, the number of characters indicated by overflow is naturally arranged from the end of the line. Details of this natural arrangement processing will be described later with reference to the flowchart of FIG.

The hanging character arrangement processing can be performed as described above. Next, the above-mentioned natural arrangement processing, uniform arrangement processing,
Each processing of overflow calculation processing will be described.

FIG. 10 is a flowchart showing the processing procedure of the natural character layout processing according to this embodiment. First, in step S12.1, the character arranged at the start position of the natural arrangement is acquired. This is when the in-line character arrangement is natural arrangement (the procedure according to the flowchart is step S10.5
Is the character at the beginning of the line, and is the dangling start character in the case of the hanging arrangement (when the procedure according to the flowchart is executed in step S11.3.).

Next, the arrangement position of the natural arrangement start character is determined. As for the arrangement position, the in-line character arrangement is naturally arranged (step S1
In the case of 0.5), it is the set end, and in the case of the hanging arrangement (step S11.3), it is the set end. Therefore, in step S12.2, it is determined whether or not the currently acquired character is the character at the beginning of the line. If it is the character at the beginning of the line, the work variable kumisitan for determining the arrangement is substituted for pos in step S12.3, and 1 is substituted for the work variable count for counting the number of characters in step S12.4. It should be noted that whether or not it is a character at the beginning of a line is determined by the information on the character or line in the typesetting (for example, the object address (prev) immediately before the typesetting or the first word address in the line (first_wo
rd)) is realized by holding. For example, if prev is NULL or the address of first_word and the address of the current word are the same for a word, it can be determined that the word is the word at the beginning of a line.

On the other hand, if it is not the beginning of a line, step S1
Substituting kumisyuutan for pos in 2.5, step S
At 12.6, the number of dangling start characters counted from the beginning of the line is assigned to the automatic variable count that counts the number of characters. That is, count = word_count-overflow + 1 (4). Here, overflow is the number of hanging characters, and acquisition of the overflow value will be described later with reference to the flowchart in FIG.

In step S12.7, pos is substituted for the character arrangement position 3e (position) of the character information of the character whose arrangement is to be determined. Then, in step S12.8, it is determined whether the arrangement of all characters up to the end of the line has been determined. This judgment is made based on whether count = word_count (5) holds. When the expression (5) is satisfied, the arrangement positions of all the characters have been determined, and thus the process ends.

When the expression (5) is not established, pos to be substituted for the character arrangement position 3e (position) of the next character is calculated in order to arrange the next character on the line. That is,
In step S12.9, the character size w of the current character is set to pos.
ord_size is added, the next character is acquired in step S12.10, 1 is added to count in step S12.11, and gap is added to pos in step S12.12. Thus, when the next character pos is obtained, step S1
Return to processing of 2.7.

By continuing the above processing, the natural arrangement position of the character in the line is determined. Next, the character uniform arrangement process will be described. FIG. 11 is a flowchart showing the procedure of the character uniform arrangement process in this embodiment.

First, in step S13.1, the uniform character spacing wo
Get rd_pitch. The method of acquiring word_pitch will be described later with reference to the flowchart of FIG. Next, in step S13.2, the first character of the line to be subjected to the uniform arrangement process is acquired. Then, in step S13.3, 1 is assigned to the work variable count for counting the number of characters. Step S1
In 3.4, the work variable pos for calculating the character arrangement position
Substitute kumisitan for.

Next, in step S13.5, pos is substituted for the position position position of the character currently being processed. In step S13.6, it is determined whether or not the uniform placement process is finished. The determination condition is count = word_count-overflow (6). If Expression (6) is satisfied, it means that the arrangement positions of the characters to be evenly arranged have all been calculated, and thus this processing is ended. If the formula (6) is not satisfied, pos for the next character is acquired in step S13.7 and subsequent steps.

First, in step S13.7, the current character size word_count is added to pos. Next, step S
At 13.8, the next character to perform Haiti is acquired. Then, in step S13.9, 1 is added to count.
Furthermore, in step S13.10, gap + word_pit is added to pos.
ch is added to obtain the arrangement position pos for the next character. Then, it returns to step S13.5 and repeats the above-mentioned processing.

By continuing the above processing, it is possible to perform the uniform arrangement processing of the characters in the line. Next, a method of calculating the uniform character spacing (word_pitch) in step S13.1 will be described. FIG. 12 is a flow chart for explaining the procedure for calculating the uniform characters in this embodiment.

First, in step S14.1, it is determined whether or not there are characters to be evenly arranged in a line. The determination condition is whether or not word_count-overflow <2 (7) holds. When the expression (7) is satisfied, the character to be arranged is one character, so that the uniform arrangement processing cannot be performed.
Therefore, word_pitch = 0 is substituted in step S14.2, and this processing ends.

If equation (7) does not hold, there are at least two characters, so that they can be arranged evenly, and the processing from step S14.3 onward is executed.

First, at step S14.3, 1 is substituted into the work variable count for counting the number of characters. Next, step S
At 14.4, the first character of the line on which character arrangement is to be performed is acquired. In step S14.5, the work variable work_length for calculating the length of the character string to be evenly allocated is set to step S
Substitute the word_size of the first character acquired in 14.4.

Next, from step S14.6 to step S
At 14.9, the length of the character string to be evenly allocated is calculated. First, in step S14.6, it is determined whether or not the condition for ending the calculation of the length of the evenly allocated character string is satisfied.
The determination condition is count = word_count-overflow (8). If the expression (8) is not satisfied, it means that the next character can be evenly allocated, so that the next character is acquired in step S14.7. Then, in step S14.8, 1 is added to count. Then, in step S14.9, word_size + gap is added to work_length to update the length of the evenly allocated character string. Then, it returns to the determination of step S14.6.

On the other hand, if the expression (8) is satisfied in step S14.6, it means that the length of the evenly-allocated character string has been determined. Therefore, in step S14.10, the difference between the line length and the character string length is determined. The distance is calculated by distance = kumisyuutan-kumisitan-work_length (9).

In step S14.11, the uniform character space word_pitch in the uniform allocation is obtained. word_pitch is di
It is a value obtained by dividing stance by the number of uniformly allocated characters-1. That is, the uniform character spacing is calculated by word_pitch = distance / (word_count-overflow + 1) = distance / (count + 1). Next, step S1
The calculation of overflow in 1.1 will be described. FIG.
3 is a flowchart for explaining the overflow calculation procedure in this embodiment.

First, in step S15.1, it is determined whether or not the line is for the hanging process. The determination condition is kumisyuutan-kumisitan <length (10). If the formula (10) is not satisfied, the lines do not overflow, so that the hanging is not performed. Therefore step S
At 15.2, overflow = 0 is substituted, and this processing ends.
On the other hand, if the expression (10) is satisfied, a line overflow has occurred, and therefore, the number of overflowed characters is obtained and substituted into overflow in the processing from step S15.3 onward.

First, in step S15.3, 1 is substituted into the work variable count for counting the number of characters. Next, step S
At 15.4, the first character (and character information) of the line is acquired. Then, in step S15.5, the word_size of the character acquired in step S15.4 is substituted for the work variable work_length for calculating the length of the character string.

Succeedingly, in a step S15.6, it is determined whether or not the character being processed is a dangling start character. The judgment condition is kumisyuutan-kumisitan <work_length (11). If Expression (11) does not hold, it is considered that the state is not yet in the hanging state, and work_len when the next character is arranged by steps S15.7 to S15.9.
Determine gth and determine whether it is a dangling start character. That is, in step S15.7, the character (character information) to be arranged next is acquired, and in step S15.8, count is obtained.
Is added to. Then, in step S15.9, work
_length is the word of the character acquired in step S15.7_
Add size and gap. As a result, the character string length (work_length) when the character acquired in step S15.7 is arranged
Is obtained, the process returns to the determination in step S15.6.

On the other hand, in step S15.5, the equation (11) is obtained.
If is true, overflow occurs in step S15.10.
Ask for. Since overflow is the number of characters up to the end of the line including the character currently being processed, overflow = word_count-count + 1 (12). word_count is the total number of characters in the line obtained in step S9.5 (FIG. 7) described above. Over ov
The erflow calculation process ends.

By executing the above processing,
It is now possible to place (hang) any specified characters that are hung.

<Display Method of Arranged Characters> For a character arranged in a line whose baseline is represented by baseline, the coordinate value (posi
The character can be displayed by displaying the character indicated by code in (tion, baseline). Here, it goes without saying that the display includes a display on the display device 1 and a visible display by a recording device such as a printer.

As described above, according to the present embodiment, by designating a desired range in a character string, it is possible to easily set "hanging" character arrangement information (FIG. 2). It is now possible to change the placement position of characters locally.

For this reason, it becomes possible to arrange the hanging of arbitrary character data and the like as intended by the text creator by a simple operation, and the work of the text creator for creating the text is improved.

Further, a part of the character data which is set to set the restriction of the character arrangement position is specified by specifying a desired range of the character string displayed based on the document data. It becomes possible to interactively specify the characters whose character arrangement positions should be restricted, which improves operability.

When hanging is specified as the restriction of the character arrangement position, the character string to be displayed in one line is determined so that the character specified as the hanging character does not come to the beginning of the line.
Overflow is detected based on the difference between the character string length required for the character string to be displayed in one line and the line length of the normally arranged line,
When the overflow is detected, the character string in the line length is arranged in the normal arrangement line, and the character string in the overflow is added to the normal arrangement line and arranged on the same baseline. In this way, since it is possible to distinguish between the normal arrangement line and the overflow portion, it is possible to arrange the characters in the normal line in an even arrangement and arrange the characters in the overflow according to the pitch of the character information of each character. It becomes possible and various character arrangements can be realized.

Further, by further comprising display means for displaying the document data according to the character arrangement decided by the deciding means, when the limitation of the character arrangement position is set, the result can be confirmed quickly. Become. It should be noted that this display includes display on a monitor screen or recording display on a recording medium by a printer.
