Abstract

PURPOSE:To improve document editing efficiency by displaying a floating area by automatically expanding the row height of a row including the floating area or compressing the height of the floating area when the preset height of the floating area is superimposed on an adjacent row by performing document edit. CONSTITUTION:A row constitution processing means C comprises character string data at every row from the character string data and row information stored in a character string data storage means A and floating area data stored in a floating area data storage means B, and a height comparison means E compares the row height of each row with the height of the floating area corresponding to floating mark data on the row, and judges whether or not the height exceeds the row height. When the height of the floating area exceeds the row height, a row expansion means F displays the floating area after automatically expanding the row height to the height of the floating area, or it is displayed after automatically compressing the height of the floating area to the row height with a floating area compression means G.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a document editing device that has a function of setting a floating area within the lines of a document to be edited. [Prior Art] Generally, in document editing devices such as word processors and desktop publishing, when editing a document, if you want to insert a mathematical formula or figure that cannot be expressed with normal characters, you can enter a height and width to create a floating area within a line. There are some that have the function of providing

This floating area is stored as floating mark data in the text storage unit of the document editing device, and for example, as shown in FIG. 14(a), floating mark data ■, ■,
is memorized. Then, as shown in the same figure (b), when character data "ΔΔΔΔΔΔΔ" is inserted before the floating mark data ■, the subsequent character string data moves backward by the number of characters inserted, and the character data before the floating mark data If you delete character data,
Subsequent character string data will be moved forward by the number of deleted characters, and the line structure will also change. Since the floating mark data also moves along with this character string data, the corresponding floating area moves in the character direction as the floating mark data in the line is displayed. At that time, if the floating area indicated by the floating mark data extends beyond the end of the line, the entire floating area is moved to the beginning of the next line, so unlike fixed areas, if the character string changes due to document editing, The advantage is that there is no need to reconfigure the settings. However, after setting this floating area, as shown in FIG.
If it is set to be narrower than the height H of the floating area 43, the floating area and the lines above and below (in the case of horizontal writing) will overlap. Conventionally, in such a case, as shown in FIG. 15(b), a new line mark is inserted between the line in which the floating area 43 is provided and the line adjacent thereto to free up one line's worth of space. I left them open so they wouldn't overlap. [Problems to be Solved by the Invention] However, in the above-mentioned document editing device, a line break operation must be performed every time a floating area overlaps an adjacent line during document editing, which is a burden to the operator. Ta. Also. If a line break is applied to eliminate the overlap with m adjacent (upper and lower) lines, for example, in the example in Figure 15(b), the space between the characters "5" and "6" and between the floating area and "10" There was a problem in that the spaces between them were line breaks, which caused them to not connect, and the advantage of floating areas was lost. This invention was made in view of the above points, and is designed to automatically prevent the floating area set during document editing from overlapping when there is a format change that would cause the floating area to overlap an adjacent line. The purpose is to avoid losing the advantages of floating areas. [Means for Solving the Problems] This invention has been made to achieve the above object, and as shown in the functional block diagram of Fig. 1, a character string consisting of character data and floating mark data. data, and 1
A character string data storage means A that stores line information indicating line separation and line height, and floating area data that represents the height and width of the floating area corresponding to the floating mark data stored in the character string data storage means A. Floating area data storage means B to store
and a line configuration processing means C that configures character string data for each line using the above character string data, line information, and floating area data.
and a display means D for displaying character string data for each line constructed by the line structure processing means C, the line height of each line and the line constructed by the line structure processing means C. A height comparison means E compares the height of the floating area corresponding to the floating mark data existing in the area to determine whether the height exceeds the line height; A line expanding means F is provided for expanding the line height of a line determined to exceed the line height to the height of the floating area and displaying it on the display means D.

Furthermore, in the above document editing device, instead of the line expansion means F, the height of the floating area of the line determined by the height comparison means E to exceed the line height is reduced by the line height. A floating area reduction means G may be provided for displaying on the display means D. Furthermore, it is preferable to provide both a line expansion means F and a floating area reduction means G, and an expansion/reduction specifying means H for specifying and validating either one of them. [Operation] The document editing device according to the present invention converts the character string data and line information stored in the character string data storage means A and the floating area data stored in the floating area data storage means B into line configuration processing means. C composes the above character string data line by line, and the height comparing means E compares the line height of each composed line with the height of the floating area corresponding to the floating mark data existing in that line. , determine whether the height exceeds the line height. If the height of the floating area exceeds the height of the line, the line expansion means F automatically expands the height of the line to the height of the floating area and displays it, so there is no need to bother with line feed operations. Since there is no storage space and only a minimum amount of expansion is required, the advantages of floating areas are less likely to be lost. Alternatively, if the floating area reduction means G automatically reduces the height of the floating area to the line height and displays it,
Although the floating area becomes narrower, the loss of the advantages of the floating area is completely eliminated.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained in detail with reference to FIGS. 2 to 13. FIG. 2 is a block diagram showing the configuration of a document editing device according to the present invention. This document editing device consists of a keyboard 1 as an input device, a microcomputer (CPU) 2, a memory 3 such as RAM and ROM, a storage device 1!4 such as a floppy disk device, and a display device Its such as a CRT. are connected via a bus line. The keyboard 1 has keys for inputting letters and numbers and keys for instructing various functions related to document editing, including inputting character data, floating mark data, inputting the height and width of a floating area, and expanding lines or reducing an area. Input instructions to enable one or the other, input to execute line expansion or area reduction, etc. The CI'U2 controls the entire document editing device, and also controls the line configuration processing means C, height comparison means E, and line expansion means F shown in FIG.
, implements the floating area reduction means G and processes other functions related to document editing. The memory 3 is a work area that temporarily stores floating area data corresponding to character string data and floating mark data input through the keyboard 1, and processes the data by the CPU 2. It also serves as a work area when reading and editing document data. That is, it serves as the character string data storage means A and the floating area data storage means B shown in FIG.

The storage device 4 is an external storage device that stores edited sentence a data including the character string data and floating area data edited in the memory 3. The display device 15 is, for example, a display device such as a CRT or LCD (referred to as rcRTJ in the following explanation), and displays character string data and floating area data stored in the memory 3, as well as various other instruction messages for the operator. Next, FIG. 3 is a block diagram showing the detailed functional configuration of the CPU 2 and memory 3 in FIG. 2, and the same parts as in FIG. 2 are given the same reference numerals. When a key is pressed from the keyboard 1, data corresponding to that key is sent to the input character identification section 7 via the input control section 6.

The input character identification section 7 identifies the sent data and sends it to one of the character input processing section 8, floating area input processing section 9, line format input processing section 10, format input processing section 11, and editing processing section 12. ．． After receiving the character data and storing it in the character string data section 13, the character input processing section 8 transfers the processing to the page composition processing section 17. The floating area input processing unit 9 receives the floating mark data, the normal specifications of the height, width and attributes of the floating area, the line extension specification, the floating area reduction specification, and the floating actual data, and inputs the floating mark into the character string data unit 13. The data is stored together with the character data, and the floating actual data and the height and width of the floating area are stored in the area data section 14. Note that floating actual data is stored in a table that stores floating areas. Then, the process is transferred to the page configuration processing section 17. The line format input processing section 10 inputs the line format information of the line pitch and line attributes sent from the input character identification section 7 to the line format data section 15.
, and the processing is transferred to the page configuration processing section 17. The format input processing section 11 receives page format information such as paper size, paper direction, margins, columns, etc., and inputs it to the page format data section 1.
The page structure processing section 17 then stores the page structure in the page structure processing section 17. Further, instructions for editing functions other than those mentioned above are sent to the editing processing section 12 for processing. The page configuration processing unit 17 performs processing to configure a page based on the character string data configured for each line by the line configuration processing unit 1. The page configuration data unit 18 stores information for each page configured by the page configuration processing unit 17. On the 1st day of the processing department,
The string data read from string data section 1-3,
The height and width of the floating area read from the area data section 14, line format data section 15, and page format data section 16, respectively,
Processing to determine line height for each line based on line format information, page format information, and line height data, and process to determine in-line addresses of floating areas are performed.

The line configuration data section 21 stores the character string data at the beginning of the line constructed by the line configuration processing section 19, and the area position data section 22 stores the character direction and line direction address within the row of the floating area. ．． The page display processing unit 23 performs a process of displaying the page configured by the page configuration processing unit 17, and transfers the process of displaying each line to the line display processing unit 24. The line display processing unit 24 uses the information stored in the line configuration data unit 21 and the area position data unit 22 to create display data for each line when displaying character strings on a page by the processing of the page display processing unit 23, and The display processing unit 25 creates display data of the floating actual data of the floating area corresponding to the floating mark data. The display memory 2B stores the display data created by the line display processing section 24 and the area display processing section 25, and the display control section 27 controls the CRT 5 and displays the display data on the screen of the CRT 5. Display it. FIG. 4 is a flowchart of line structure precept processing by the line structure processing section 19 of FIG. First, in step 1, the character width addition value (N) and the maximum line height value (MAX) are each reset to O. This character width addition value (N) is a variable that adds the character width each time character string data is read, and the maximum value (MAX) of the line height is the value of the character string data when that line is read. This is a variable that determines the line height. Next, in step 2, character string data is read one character at a time from the character string data section 13, and in step 3, it is determined whether it is a sentence end code or a line feed code.

Based on this judgment, if it is an end-of-sentence code or a line feed code, proceed to step 4, read the first character of the next line, and return. In step 3, if the code is other than a sentence end code or line feed code, proceed to step 5, and judge whether or not it is floating mark data. Based on this judgment, if it is floating mark data, proceed to step 6, set the width of the floating area corresponding to the floating mark data in the area data section 14 as the character width, and check whether the attribute of the floating actual data is specified as line extension in step 7. Decide whether or not.

If line extension is specified in step 7, proceed to step 8 and change the height of the floating area to the line height and proceed to step 10; if line extension is not specified, proceed to step 9 and leave the line height unchanged. and proceed to step 10. Then, in step 10, the address of the floating area in the character direction is stored in the area position data section 22, and step 12
Proceed to.

In step 5, if it is not floating mark data, the process proceeds to step 11, where the line configuration data section 21 stores the line height and character width corresponding to the character height, and the process proceeds to step 12.

In step ↓2, the character width addition value (N) is compared with the line width, which is the length of one line, and if the line width becomes smaller, it means that the configuration of one line has been completed, and the process proceeds to step 4.

Based on this comparison, if it is less than the line width, proceed to step 13,
Step 6 or Step 11 for character width addition value (N)
The character width in is newly added, and the process proceeds to step 14.

In step 14, the line height (MAX) is compared with the line height determined in step 8, step 9, or step 11, and if the line height is larger, in step 15 this line height is changed to the line height (MAX). ), and if the line height is less than the line height (MAX), return to step 2. Initially, line height (MAX) =
Since it is O, naturally [MAX<line height], and the line height determined in the above step is set as the line height (MAX). In this way, read the string data one character at a time,
If the height of the floating area exceeds the line height (MAX) corresponding to the character height, the height of the floating area is set to the new line height (MAX).
) and stores the address in the character direction of the floating area in the area position data section 22 until the character width of the read character string data exceeds the width of one line to form a line. Next, when the line configuration processing is completed, page configuration processing is performed by the page configuration processing section 17. The page configuration process will be explained using the flowchart shown in FIG. When the above-mentioned line composition processing is completed in step 20, it is determined in step 21 whether the line fits within the page. If the line does not fit within the page, the process proceeds to step 26, but if it does, step 2
In step 2, the row configuration data is stored in the row configuration data section 21, and in step 23, the address of the floating area in the row direction is stored. Then, in step 24, it is determined whether or not it is a page break code. If it is a page break code, proceed to step 26; if it is not a page break code, proceed to step 25. In step 25,
It is determined whether or not it is an end-of-sentence code, and if it is an end-of-sentence code, the page configuration process is ended, and if it is not an end-of-sentence code, the process returns to step 20. In step 26, the next page configuration data is read from the page configuration data section 18, and the process returns to step 20. When the line configuration processing and page configuration processing are completed in this manner, the line display processing section 24 performs line display processing to display the lines.

The line display process will be explained using the flowchart shown in FIG. First, in step 30, character string data is read character by character from the character string data section 13, and in step 31, it is determined whether or not it is the first character of the next line by referring to the line configuration data in the line configuration data section 21.

If it is other than the first character, the process advances to step 32 to determine whether or not it is floating mark data, and if it is floating mark data, the process advances to step 33 to determine whether the :4 dynamic area attribute is designated as area reduction.

If area reduction is specified, the process proceeds to step 34, where the area display processing unit 25 reduces the height of the floating area to the line height, and the display control unit 27 displays the floating area on the CRT.
5 on the screen and return to step 30. If area reduction is not specified, the process proceeds to step 35, displays the floating area as is, and returns to step 30. If area expansion is specified, the line height is expanded to the area height as necessary in the line configuration process shown in Figure 4, so even if the floating area is displayed as is in step 35, adjacent lines It does not overlap with the characters.

If it is not floating mark data as determined in step 32, the process advances to step 36, character data is displayed, and step 30
Return to. In this way, when it is determined in step 31 that the read character string data is the first character of the next line, the display process for one line is ended.

FIGS. 7(a) and 7(b) are diagrams showing display examples of lines including floating areas. In other words, when the attribute of the floating area is specified as line expansion, as shown in FIG. The row height h of the row including the floating area 28 is expanded to the height H of the floating area 28 and displayed. Further, when the attribute is designated as area reduction, the height H of the floating area 2 days is reduced to the row height h of the row and displayed, as shown in FIG. 2(b).

Next, setting of the floating area will be explained with reference to the flowchart of FIG.

When the operator selects the task of creating a new floating area within the line, the menu shown in FIG. 9 is displayed on the screen of the CRT 5. Then, the operator sets the height of the area according to this menu. Enter the width in the Ili column using the numeric keys on keyboard 1, and set the area attributes in the attribute setting column to ``Normal (no attribute)'', ``R line expansion'', and ``Area reduction''.
(The default is "Normal") and when you instruct "Execute" using the execution key, the height, width and attributes of that area are stored in the area data section 14 in FIG. Determine whether it is "normal" or not, and if it is not "normal", terminate the process. However, if "Normal" is specified, it is determined whether the height of the input area exceeds the line height, and if it does, a confirmation message as shown in Figure 10 is displayed. Display.

If "cancel" is instructed by the cancel key, the menu shown in FIG. 9 is displayed again and the process returns to inputting the height and width.

When "execute" is instructed by the execution key, this process ends.

Next, a display example of an edited document when the attribute is set to line expansion will be described.

FIG. 11(a) is an example of character string data stored in the character string data section 13.
"wo", "J='J*'de", etc. are character data at the beginning of the line, and ■, ■, ■ are floating mark data. The line structure of this character string data is determined by the line structure data table 40 as shown in FIG. 11(b) provided in the line structure data section 21 of FIG. character data ``uki'', ``wo'', r necessary'', r-J, r
The songs are stored in the order of songs. In addition, the floating actual data corresponding to ■ and ■ of the floating mark data are stored in the floating area table 41 in the area data section 14 as shown in FIG.
are stored in each. Then, the height of the area of floating actual data A and B indicated by floating mark data ■ and ■ exceeds the line height of that line,
Assuming that line expansion is specified as an area attribute, the display on the screen of the CRT5 in which the character string data and floating actual data are combined is the second line containing floating actual data A and B, as shown in Figure 13. The row height of the third row containing . is expanded to the height of the floating real data A and B areas.

〔Effect of the invention〕

As explained above, the sentence Wm collection device according to the present invention is
If the height of the set floating area overlaps an adjacent line due to document editing, the line height of the line containing the floating area will be automatically expanded or the height of the floating area will be reduced and displayed. Therefore, when editing a document, there is no need to reset the floating area or perform extra line feed operations, improving the efficiency of document editing.

Furthermore, the advantage of floating areas, in which a series of character strings and floating areas always move in a connected manner, is almost never lost.
