Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a document processing device that allows easy editing of tables.

[Conventional technology]

In the tabulation method used in conventional document processing devices, the means for drawing ruled lines are as follows: (1) Two points, a starting point and an ending point, of the ruled line are specified.

(2) Specify the number of lines to be drawn, calculate the position of the ruled line by dividing the distance between the standard ruled line already drawn and the specified position by the number of lines to be drawn, and calculate the position of the ruled line. Place the ruled line □ of the position on the grid that is the nearest grid point (see Figure 2).
a), (b) 100).

This method was used.

This will be explained based on FIG. 15 in FIG. 2(a) is a reference line. The distance between this reference line and the cursor 2o (if the reference line is a horizontal ruled line, the difference in the y coordinate; if the reference line is a vertical ruled line, the difference in the X coordinate; in this example, the difference in the y coordinate) is the number of ruled lines. Divide by 5 to find the interval between ruled lines. If the positions of the five ruled lines are determined at this interval, the result will be as shown by the dotted line 16 in (a). By aligning the positions of these ruled lines to the nearest grid 100, a result as shown in FIG. 2(b) is obtained.

But - do tables used for boat fishing documents have equal line widths?
Even though there are many tables, with the divided ruling method described above, as shown in FIG. 2(b), there is a deviation by the maximum nigerid interval, making it difficult to draw evenly spaced ruled lines. Furthermore, in order to create one table, a ruled line that is parallel to one ruled line and has the same length is drawn each time, making the operation complicated.

〔the purpose〕

In view of the above points, it is an object of the present invention to provide a document processing device that can draw equally spaced ruled lines on a sheet of paper according to a specified grid (size information) with a simple operation.

〔Example〕

Hereinafter, the present invention will be explained in detail using the drawings. Note that a document in the present invention is a text (including a table) and one figure.

This is a general term that includes images, etc. Furthermore, as long as the functions of the present invention are executed, it does not matter whether it is a single device, a system consisting of a plurality of devices, or a system in which processing is performed via a network such as a LAN. It goes without saying that the present invention is applicable. Note that the basic idea of the document processing of the present invention was to electronically perform the process of drawing by a person on a desk with a pen, etc. In the specification, "drawing a line", "moving", etc. are all electronically processed.

[System Block Diagram] FIG. 1 is a system block diagram of a document processing apparatus according to an embodiment of the present invention. 1 is a CRT unit used in the raster scan display system, 2 is a video RAM (VRAM) that stores display pattern information for one screen, and 3 is a VRAM.
This is a display control unit that controls writing of pattern information to CRT1 and reading of pattern information to CRTl. 4 is a microprocessor (MPU) which is the main control of this device. Reference numeral 5 denotes a main memory having an area for storing control programs and document data as shown in the flowchart described later. Connected to the MPU 4 are a keyboard 8 for inputting character data, etc., and a pointing device (hereinafter referred to as P and D) 9 for specifying a position on the CRT and inputting and editing data such as graphics. Reference numeral 6 denotes a hard disk device in which document files, programs and character fonts as shown in the flowcharts described below are stored. IO is a printer for outputting created documents, and has a double-sided printing machine and the like. 11 is an image scanner for reading image data such as images, and 12 is a floppy disk device for storing document files and the like. Each of these constituent blocks is connected by an I10 bus 7.

[Document editing screen] The document editing device configured as described above uses CRTl to edit the lettering, character arrangement, and print format based on typesetting rules.
Using the keyboard 8, P, and D9, quick document editing can be performed on any area on the screen, or even on a frame area within that area. FIG. 3-1 shows an example of a document editing screen, where 20 is a cursor operated by P and D, and 21 is a paper window displaying a print format on the screen. As shown in Figure 3-2, the paper contains characters 50, figures 51, images 52, and forms 5.
3 data can be input. Each item is prioritized and displayed in the following order: form, image, shape, and text. Note that the tables described below are considered to be equivalent to the above characters. Reference numeral 22 in FIG. 3-1 is a user menu in which a kana-kanji window for character input and function keys for function selection are displayed. A status line 23 displays the keyboard input mode, messages to the operator, and the like. Reference numeral 24 denotes a frame-open area on the paper (hereinafter referred to as a frame). Within the frame, text (small set), table layout, and graphic image data can be input, and as with the paper, they are superimposed and displayed according to their priority order. be done.

[Word Processor Editing] Next, each editing function will be explained. Word processor editing allows you to input and edit characters on paper or in frames. Character input is performed using functions such as romaji-kana conversion and kana-kanji conversion. Each paper has a format assigned to it.
Paper size, the position of the hanmen (the area for inputting and editing documents, etc. on the paper), the number of columns, the number of lines in the film, the text size, the font (Mincho, Gothic, etc.), non-pull (page number) ), columns (margin headings), etc. are defined. Characters are organized and displayed or printed according to this format. Editing functions also allow partial character size and font changes, character decorations such as underlining, accent marks, ruby, superscripts, and subscripts, and line alignment such as centering, right alignment, left alignment, and equal allocation. It also has a search and replace function that searches for a string and replaces it with another string. It also has a floating frame editing function that allows you to move, input, or delete characters, move to follow the characters, empty the floating frame, change the size, delete it, etc.

[Shape editing] Next, shape editing includes editing functions such as inputting shapes such as straight lines, circles, rectangles, and ellipses, changing area and line type, moving, copying, erasing, transforming, rotating, enlarging, and reducing shapes. , is composed of multiple layers, and has functions such as a multilayer structure that allows each layer to be displayed and edited individually, and multiple layers to be displayed overlapping each other.

[Image editing] Image editing involves inputting images from an image scanner,
It has functions for rotating, reversing, moving, copying, and erasing image data, as well as editing in dot units, and trimming to partially cut out image data.

[Fixed frame editing] Next, unlike floating frames, fixed frame editing is a frame that is opened at a fixed position on the paper, and has functions such as opening, resizing, moving, and erasing frames that do not depend on the movement of characters.

[Table Type Processing Next, table type processing, which is the center of the present invention, will be explained. Editing can be performed on frames that do not contain subgroups. Functions can be broadly divided into two: ruled line editing, which allows you to draw, move, and delete ruled lines, and character editing, which allows you to input all characters and make decorations such as underlining and ruby. The purpose of ruled line editing is to create a table by drawing ruled lines, and to create a rectangular area surrounded by ruled lines called a cell. Text can be entered into this cell. The purpose of text editing is to input text into cells created by border editing. By using these two editing functions,
You can quickly (and easily) create high-quality and complex tables.

[Table data table layout] Figure 4 is a diagram showing an example of the layout of a table data table, which is part of the document data on the hard disk.
-Frame as shown in Figure 2) Consists of an attribute table. The control table is for managing the entire table data table. 5tat stores a number representing the tabular data type. measr stores control information for conversion from internal storage coordinate units to CRT or printer coordinate units. Next, offsets and counts of diagonal lines, horizontal lines, vertical lines, text, and cell attributes are stored. The offset is data indicating the starting point address of the diagonal line, horizontal line, vertical line of the ruled line table, the text data table, and the table area of the cell attribute table. Also, the count indicates the number of records for diagonal lines, horizontal lines, vertical lines, text, and attributes, with n1 records for diagonal lines, n2 records for horizontal lines, and n3 records for vertical lines.
, n4 text records, n cell attribute records
There are 5 pieces. These offsets and counts allow the areas of the ruled line table, text table, and attribute table to be grasped.

[Figure 4 Ruled Line Table] The ruled line table is a collection of information on diagonal lines, horizontal lines, and vertical lines. PO3(x,y) stores the starting position of each line. 1ine 5style stores information representing the line type of each line, such as a solid line or a dashed-dotted line.

1ine width stores information about the thickness of each line. Flag stores lock information for each ruled line. "roand" stores information about corner rounding at the intersection of a horizontal line and a vertical line. len of horizontal line record, vertical line record
gth stores information about the length of each line. diagonal w
-1ength and h-1ength store length information in the horizontal direction and vertical direction, respectively. The text offset of the horizontal line record stores an offset indicating at which position in the text table the text data corresponding to the cell that the horizontal line constitutes is stored. If there is no text, a value of -1 is stored. Each record of the ruled line table is arranged in diagonal lines and horizontal lines in ascending order of X coordinate values, and vertical lines in ascending order of y coordinate values, based on the start position information indicated by PO3 (x, y). Note that this ruled line may be called an elemental piece that constitutes a cell.

[Figure 4 Text Table] The text table is composed of variable length text records. The attribute offset is the attribute of the text, such as writing direction (vertical writing/horizontal writing), font size, left, right,
This is an offset indicating where in the cell attribute table, character alignment such as centering, line spacing, character spacing, etc. are stored. The text count stores the number of characters of text data. The text data is an array of character codes and consists of text count 2-byte codes. A flag indicating the display state of the cell is set in flag. One text record exists for each cell having characters or attributes, and there is always one attribute record for this text record. However, the same attributes are assigned to texts that have exactly the same attributes.

[FIG. 4 Cell Attribute Table] The cell attribute table is composed of variable length cell attribute records. attrsiz is the size of one cell attribute and stores the number of bytes. flg stores a flag indicating whether it is used or not. m e s h stores the middle paint pattern number of the cell.

K um -f stores flags indicating vertical or horizontal writing, a designation of 9-character pitch between characters, and a flag of designation of 2-line pitch. aldp is above.

Information on bottom, left, and right character alignment, rotation angle for rotated display, and display method (outline, overwriting, etc.) is stored. f
Ont stores information about character fonts (Mincho, Gothic, etc.). ps stores the character size. 1ns
For p and chsp, values of line pitch or line spacing, character pitch or character spacing are stored according to k um -f. l r
m g n and u d m g n store the values of left and right and top and bottom margins.

The operator can draw the lines graphically as shown in Figure 1O as described later by using divided rules and continuous rules, which will be described later.However, internally, the vertical and horizontal rules are As shown in the figure, the data is divided at the intersection and stored. Since it is memorized like this, when drawing a table, do it graphically and edit each cell (delete only the left side of one cell, etc.)
When doing so, it becomes possible to do so for each elemental piece. or,
The text data of each cell is held by the upper left horizontal ruled line (the ruled line indicated by the thick line in FIG. 5-2) among the ruled lines constituting each cell (FIG. 5-2).

[Divide ruled lines] Using Figures 6 to 8, draw multiple parallel ruled lines at equal intervals. (The method will be explained. Figure 6 is a control flowchart. When you instruct to draw rules, the division number input window shown in Figure 7-40 is displayed.At 5 tepl in Figure 6, enter the number of parallel and evenly spaced ruled lines (divided ruled lines) (number of divisions) from the keyboard.
Enter. FIG. 7 shows that the number of divisions has been input as 10. In step 52, a reference line 41 in FIG. 7, which serves as a reference for dividing ruled lines, is determined. To do this, move the cursor 20 using P and D on the ruled line that has already been drawn, and press the P and D buttons once (hereinafter referred to as 1 click), or draw the ruled line (P and D at the starting point of the ruled line). The reference line is determined by pressing the button, moving the cursor to the end point while holding it down, and releasing the button. Next, in step 3, move the cursor to any position and press the P and D buttons to determine the distance between the reference line and the cursor position (y
By finding the difference in coordinates (or the difference in the X coordinate in the case of vertical ruled lines) and dividing this distance by the number of divisions, the distance between the divided ruled lines (Ll in Figure (a) for the S-th line) is determined. In addition, in FIG. 8-1, it is a horizontal ruled line. Next, in step 5, the distance obtained in step 5 is approximated to an integral multiple of the grid interval so that all the divided ruled lines are aligned with the grid 100.

The approximation is done by. Since the division is performed by rounding down to the nearest whole number, the value obtained is obtained as an integral multiple of the grid interval (L2 in Fig. 8-1(b)). Next, 5t in Figure 6
In ep5, display as many divided ruled lines as the number of divisions at the divided ruled line interval determined in 5tep4 (Fig. 8-2 42
). The above steps from step 3 in FIG. 6 are repeated until the P and D buttons are released. The operator moves the cursor while pressing the P and D buttons until the ruled line spacing is appropriate.

Accordingly, a plurality of equally spaced ruled lines are displayed in real time.

By releasing the P and D buttons, the ruled line interval is determined and a record of divided ruled lines is registered.

[Continuous Rule Drawing] Next, a method for continuously drawing parallel ruled lines at arbitrary positions will be explained. It is started by instructing continuous ruling using the keyboard or P or D. A control flowchart for continuous ruling is shown in FIG. 9-1.

First, a reference line is determined at 5 tepl. This is P,
Move the cursor onto the ruled line already drawn by D,
It is determined by one click or by drawing a ruled line (FIG. 9-2 41). Next, in step 2, move the cursor 20 to the position where you want to draw a ruled line parallel to the reference line and click once. ! :5In steps 4 to 7, if the reference line is a vertical ruled line, register the record in which the X coordinate of the reference line is replaced with the coordinate of the grid closest to the click position if the reference line is a horizontal ruled line, and the y coordinate is replaced with the coordinate of the grid closest to the click position (FIG. 10). From step 2 onwards, parallel lines can be drawn continuously by repeating l-clicks.

[Delete ruled lines] Moving text data by deleting ruled lines will be explained.

First, FIG. 11(a) is a control flowchart regarding deletion of horizontal ruled lines. Check whether the horizontal ruled line to be deleted in step 5 has text (whether the text offset of the horizontal line record in Figure 4 is not -1), and if it does not have text (if it is -1), delete the horizontal ruled line record (step 5). ). If you have text, check in step 5 whether or not there is a cell above the horizontal ruled line, and if it is not a cell, erase the text data in step 4, and erase the ruled line data in step 5 (step 12-
Cases such as the erasure of H3 in Figure 1(b)). When the top is a cell (as in the case of erasing Hl in 12-1(a)), it is treated as if cells C1' and C2 are combined by erasing the i-line, and the text data of Hl is created in step 3. This is combined with the text data held in H2, which is the text data in the upper cell, to obtain a result as shown in the left diagram of FIG. 12-1(a).

Note that text synthesis in the present invention is performed based on the attributes of the cell to be synthesized using the aldp or the like of the cell visceral table shown in FIG. In other words, in (a) of Figure 12-1, if one of the attributes of cell C1 is "centering", the attribute of the cell created by deleting Hl will also be "centering", and the composite text [Aa Ii Koko is centered. This also applies to other text compositions.

The rearrangement of character strings in table layout and the composition of characters will be explained using FIGS. 12-2 to 12-3. FIG. 12-2 is a diagram showing only the text table of FIG. 4. First, extract the synthesis target text as shown in (a) (in the example of Figure 12-1 (a), the text record held by H2) as shown in Figure 12-2 (b), and extract the extracted text record. The following text table (c)
Like, stuffed before.

At this time, the text 0ffset of the horizontal ruled line that holds this packed text record is shifted, so check the text offset of the record in the horizontal ruled line table in order, and check the text 0ffs that is larger than the offset of the destination text.
The text offsets of all horizontal ruled lines are corrected by subtracting the sans of the synthesis destination text from the text offset of the ruled line record with et. Next, insert the extracted destination text at the end of the text table, and set the text offset of the composite light horizontal ruled line record.
Stores the inserted position. Next, the destination text is similarly set to the state shown in e), ``Move after the destination text.''

FIG. 12-3 (a) shows the text records of the compositing source and the compositing source that have been moved to the end of the text table. Next, the header part (12th-
11O) in Figure 3(a) is taken and the subsequent parts are moved forward to make it as shown in Figure 12-3(b), and the text count of the composition source text record is added to the text count of the composition source text record.

Further, by setting the text offset of the composite light horizontal ruled line record to -1, the composition is completed.

Next, FIG. 11(b) is a control flowchart when vertical ruled lines are erased. It is checked whether the vertical ruled line to be erased at 5 tepl is a ruled line forming the left side of the cell. If not, the ruled line record is deleted in step 5 and the process ends. If it is a ruled line that forms the left side (for example, the 12th
Vl in Figure 1 (b)) The cell (Figure 12-1 (b)
Check whether the horizontal ruled line H3 at the upper left corner of C3) has text (step 2).

If you don't have it, go to 5tep4, if you have it,
Check whether the left side of the vertical ruled line is a cell (st
ep3). If it is not a cell, go to 5tep4, if it is a cell (for example, when deleting v3 in Figure 12-1 (C))
In step 4, the text of the cell on the right is synthesized (the text of H5 is synthesized with the text of H4).

[Movement of ruled lines] (Movement of horizontal ruled lines) The movement of horizontal ruled lines will be explained. FIG. 13 is a control flowchart. First, check whether the ruled line to be moved in 5tepi has text data (whether the text offset of the horizontal ruled line record in Figure 4 is not -1), and if it does not have it (if it is -1), move it as is. . 5 if you have text
In step 2, it is checked whether there is a cell above the horizontal ruled line. If it is not a cell, the text data will also move along with the ruled line (move H9 in Figure 14 (C) to the position of H9'. H9' had text, but since it is no longer a cell, the text will not be displayed. Figure 14 (C) right figure). If the top is a cell, it is checked in step 5 whether the result of moving the ruled line constitutes a cell. If the destination is also a cell (H in Figure 14(b)
8 to H8', the destination is cell 9') The text data moves together with the ruled line. If the movement destination is not a cell (Figure 14(a)) [move 6 to H6'), the text data of that border is combined with the text data of the cell above in step 4 (the text of H6 is moved to H6').
7). This synthesis is shown in Figure 12-2,
This is the same as the explanation in FIG. 12-3.

(Movement of vertical ruled lines) Next, movement of vertical ruled lines will be explained. FIG. 15 is a control flowchart. First, at 5 tepl, it is checked whether the moving ruled line constitutes the left side of the cell. If No, the ruled lines are moved in step 5 and the process ends. Yes
Then, in step 2, it is checked whether the upper left horizontal ruled line of the cell (H15 when trying to move v5 in FIG. 16(C)) has text. If No, go to step 5, and if it is, go to step 3 to check whether the left side of the moving ruled line is a cell. If it is not a cell, go to 5 step 7 (Figure 16 (c) (7) V5 to V
5'i, :Move, H15 (The D text is no longer a cell, so it is no longer displayed.) If it is a cell, proceed to 5step 4 and determine whether the movement destination is a cell. 5 for cell
tepl, the text on the upper left horizontal ruled line of the source cell is synthesized with the upper left horizontal ruled line of the destination cell (the text of H13 in FIG. 16(b) is synthesized with the text of H13'). If it is not a cell (v3 in Fig. 16(a) is
3') Upper left horizontal ruled line (Hll) of the source cell
The text of is combined with the text of the upper left horizontal ruled line (HIO) of the cell (C6) on the left side of the moving ruled line (as the text of the ruled line of HIO').

[Cell Erase] Next, a method for erasing ruled lines in units of cells without destroying cells adjacent to the cell to be erased will be explained. First, cell deletion is instructed using the keyboard or P and D. Next, if there is one cell to be erased, click that cell one time using P and D (FIG. 17(a)). If there are multiple figures, see Figure 17 (
b) Press the P and D buttons, move the cursor while holding them down to specify the range, and release the buttons. In this case, all cells touching the rectangle (indicated by the dotted line in FIG. 17) formed by the two points of the pressed and released positions of the P and D buttons are targeted for cell deletion and are displayed in reverse video. When a cell to be deleted is specified, first, the horizontal ruled line records in the ruled line table of FIG. 4 are sequentially processed as shown in the control flowchart of FIG. 18. First, 5tepl
, check whether there is a cell below the border. In other words, check whether this ruled line constitutes the top edge of the cell. If it is a cell, it is checked in 5tep2 whether the cell has been inverted (targeted for cell erasure). If it is reversed, in step 3 it is checked whether the area above the ruled line is a cell (whether it forms the bottom side of the cell).

If it is a cell, it is checked in step 5 whether the cell is inverted. If it is reversed then 5te
At p5, the text record indicated by the text offset of the ruled line is deleted, and the ruled line record is deleted. Also, if the upper cell is not inverted in 5tep4, if there is the next ruled line in 5tep8, 5te
Repeat from pl. The process ends if there is no next ruled line. or,
If it is not a cell in step 3, the text record and ruled line record are deleted in step 5. Also, 5
In tepl, there is no cell below the border, or 5te
If the cell below is not inverted in p2, 5t
In ep6, check whether the cell is above the ruled line. If it is not a cell, the process moves to the next ruled line in step 5.

Also, if above the ruled line is a cell, in 5step7,
Check to see if the cell above is flipped. If it is highlighted, the ruled line and text record will be deleted; if not, the process will move on to the next ruled line.

Next, the same process is performed for vertical ruled lines. However, in the case of vertical ruled lines, check the bottom of the ruled line in 5 tepl, 5 step 2 to the right (check llq, 5 tepa, 4.
Similar processing can be performed by checking the left side of the line in 6.7. Also, since the vertical ruled line does not have text, the text record is not deleted in step 5.

By doing the above for all horizontal and vertical ruled lines,
You can erase all the ruled lines on the boundaries between cells that are being inverted and the edges of cells with no adjacent cells, without damaging the cells adjacent to the erased cells (,
Cells can be erased.

As explained above, the present invention has the following effects.

By providing a means for drawing a plurality of parallel, evenly spaced ruled lines, and a means for continuously drawing parallel ruled lines at arbitrary positions, it was possible to quickly (tabulate) as desired by the operator with fewer operations.

When erasing or moving ruled lines, the composite light for characters is determined by considering the relationship between the left and right bottom left of the cell, which is the area where characters are input, to prevent the generation of unnecessary character data that does not belong to any ruled line. This saves document file space.

〔effect〕

As detailed above, the dimensional information (
For example, it has become possible to provide a document processing device that can draw equally spaced ruled lines according to a grid.
