Description

Description: TECHNICAL FIELD The present invention relates to a document processing method capable of setting desired frame information on a display and arranging characters.

[Prior Art] Conventionally, when a document is created by a simple document processing device called a word processor, the characters are aesthetically pleasing due to the fixed pitch, but the operation is relatively easy. . On the other hand, the document processing apparatus having the typesetting function as referred to in the present invention can change the character pitch and the size of the character for each character, so that a visually beautiful document can be output. , Its operation was relatively difficult. Therefore, it is necessary to perform the typesetting process on the document input by the word processor by the document processing method according to the present invention and output it.

[Problems to be Solved by the Invention] However, if the document created by the word processor has document data that should be treated as a table, the appearance of the document data should not be destroyed. When the document created in step 2 is read into a conventional document processing device, this data is not treated as document data that you want to treat as a table, and there is no concept of columns that make up the table, and it is simply processed as a series of document data. There is a problem that the document data input from the word processor as the document data to be handled is destroyed by the typesetting process.

[Means for solving problems]

In order to solve the above problems, the present invention displays input document information, indicates a desired area on the display, and detects character information displayed in the indicated area,
A document processing method, comprising: converting the designated area into vector ruled line data; and outputting the detected character data to an area surrounded by ruled lines output according to the vector ruled line data.

Embodiment An embodiment suitable for the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a system block diagram of a document processing apparatus according to an embodiment of the present invention.

In the figure, 1 is used in the raster scan display method.
A CRT display unit 2, a video RAM (VRAM) that stores display pattern information for one screen, and a display control unit 3 that controls writing of pattern information to the VRAM 2 and reading of the CRT. Reference numeral 5 is a main memory having a program area PA storing a control program according to the flow chart of FIG. 4, a document data storage area TXT, a table area storing table data, CTB, RTB, and CELL. Is a microprocessor (MPU), which performs the main control of this device. M
A keyboard 8 for inputting character data etc. to PU4, and C
Pointing device (P
D) 9 is connected. A hard disk device 6 stores a document file and a character file. Reference numeral 10 is a printer for outputting the created document, and 11 is a floppy disk device for inputting the document floppy created by the word processor. Each of these component blocks is an I / O.
It is connected by bus 7.

The case of handling a document having a table as shown in FIG. 9 created by a word processor will be described below. Document input by word processor is page by page floppy disk device 11
It is read into the document storage area TXT of the main memory 5.
At this time, the ruled line portion of the sentence as shown in FIG. 9 is generally represented by the JIS C6226 ruled line segment code as shown in FIG. FIG. 3 is an exploded view of the ruled line portion of FIG. 9 so that the type of the corresponding ruled line segment code can be understood.

Next, the processing relating to the table portion will be described with reference to FIG.

First, in step 6-1 the table frame is searched. This is the first process to determine the table part, and the outermost frame of the table is searched. Specifically, from the top of the page If the code is searched to the end of the page and is not found, it is determined that there is no table on that page, and the processing of FIG. 4 ends.

If found (5-1 in FIG. 3), check one character at a time in order.

The allowed code is However, if other code comes in, it means that the part you are looking at is not a table and restarts from that part. Start searching for.

When the code is found (5-2 in FIG. 3), the characters are checked downward from the page one by one. The allowed code is If other code comes in The search of step 6-1 is restarted from the part. In the same manner, the check to return to 5-1 through 5-3.5-4 in FIG. 3 is performed. When this check ends, the portion surrounded by the checked area is recognized as a table frame candidate, and the process proceeds to step 6-2.

In step 6-2, the vertical ruled lines included in the table frame candidates are registered in the vertical ruled line table CTB in the main memory 5. The details of the vertical ruled line table LTB are shown in FIG. As a rule of registration, the connected vertical ruled line is considered as one line, but if it intersects with the horizontal ruled line, cut it there and consider it as another ruled line and register it. In FIG. 3, 5-a to 5-h
Will be registered. Specifically, first If there is a ruled line segment code including vertical ruled lines, check one character at a time from the point where
Register it in the table. At this time If there is, the vertical ruled line ends there, so x
The coordinates and the y coordinates of the upper and lower edges are also registered, In this case, since the ruled line may still be present, the y coordinate of the lower end is not registered here.

In this case, one vertical ruled line is registered, and a ruled line at the lower end that has not yet been determined is registered. ) When an undefined ruled line at the bottom is registered, the characters During the period, the check progresses in sequence, and when the other code comes, the lower end is registered. At this time In the case of, the undefined ruled line at the lower end is registered again. Register the ruled lines in the vertical ruled line table while checking as described above, When the column of is reached, the processing of this column is ended. And so on Check and register in the column on the right of The same processing is performed up to the column of, and the processing of the vertical ruled line in step 6-2 is completed.

In step 6-3, the same processing is performed on the horizontal ruled line and it is registered in the horizontal ruled line table RTB in the main memory 5.

The attributes of the ruled lines in the ruled line table are all table rules here in the processing of steps 6-2 and 6-3, but if ruled line segment codes other than those shown in FIG. Will be registered.

In step 6-4, based on the ruled line tables CTB and RTB registered in this way, it is checked whether the areas delimited by the ruled lines in the frame of the table are all rectangular. First, one vertical ruled line is obtained in order from the vertical ruled line table CTB, and the connection with other vertical ruled lines is examined. Here, the one that is connected is considered to be one here, and both ends of the vertical ruled line are found. Next, for each of these both endpoints, the horizontal ruled line table RTB is checked to determine whether or not there are two horizontal ruled lines each having the endpoint as the endpoint.
Find out with. If there are not two, it is 5-1 in FIG.
Check if it is a point of 5-2, 5-3, 5-4, and if it is not, there is a non-rectangular area. Therefore, regarding the frame candidate of this table, assume that it is not a table here, and the processing of FIG. 6 is performed. finish.
Similarly, all the ruled lines registered in the vertical ruled line table CTB are checked, and when finished, the ruled lines are sequentially picked up one by one from the horizontal ruled line table RTB and the same check is performed. When the above checks are completed, all the parts delimited by the ruled lines in the frame of this table can be considered as rectangles.

Finally, the cell data of step 6-5 is registered. This process fetches one ruled line in order from the horizontal ruled line table RTB, searches the vertical ruled line table CTB for the vertical ruled lines that extend below it at both ends, and if not, the horizontal ruled line that connects to the contact There should be a line, and it is searched from the horizontal ruled line table RTB, it is considered as one line including the original ruled line, and the vertical ruled line extending below the end point is searched again. If there is a vertical ruled line, it becomes the edge of the cell. In this way, the left and right ends of the cell are determined, and then the lower end of the cell is determined based on either one of the left and right vertical ruled lines. This is the lower end and the end point of the vertical ruled line, the horizontal ruled line extending in the original horizontal ruled line direction is searched from the horizontal ruled line table RTB, and if there is, the position is the lower end of the cell. If there is not, there should be a vertical ruled line with the end point as the upper end point, and it is searched from the vertical ruled line table CTB, and the horizontal ruled line table RTB is similarly searched for the lower end point. The lower end of the cell is determined by repeating the above.

When the cell range is determined, it is registered in the upper left x-coordinate, y-coordinate, lower right x-coordinate, y-coordinate of the cell table CELL in the main memory 5, and further included in the cell based on the range. A character string is determined, the character string is stored separately, and a pointer to the character string is registered in the cell table CELL. Details of the cell table CELL are shown in FIG. 5 (b).
The above processing is performed from the horizontal ruled line table RTB 5-4 to 5-3.
By performing for the lines other than the horizontal ruled lines that make up the
All cells in this table are cell tables as shown in Fig. 5 (b).
It is registered in CELL and the character string contained in the cell is also determined.

With the above, the processing of FIG. 4 is completed, the table portion of the document of FIG. 9 is recognized as a table, and the information about the ruled lines and the information about the cells are all registered in the tables CTB, RTB, and CELL of FIG. .

Therefore, in this document, the text part is typographically formatted with the frame part of the table as the prohibited area, and the table part is created with ruled lines from the tables CTB and RTB in FIG. 5, and the characters in each cell are the cell table. When the typesetting in the cell is performed based on the information of CELL, it is output in the typeset state while the format of the table as shown in FIG. 6 is maintained.

In this way, a document created such that the outer frame of the table as shown in FIG. 9 is rectangular and all the areas delimited by the inner ruled lines are also rectangular can be used as it is.

Next, a case of handling a table created in an incomplete form as shown in FIG. 7 will be described. It is possible to determine that such a document is not a complete table when the process of FIG. 4 checks that the area formed by the ruled lines in step 6-4 is all rectangular. In such a case, that page of the document is then displayed on the CRT1 with a fixed pitch, similar to the display on a word processor. Then, the operator operates the pointing device 9 to add or delete ruled lines on the CRT 1 to create a complete table. Specifically, in the case of adding a ruled line, both ends of the ruled line to be added are instructed, and when the instruction is given, the device first determines from the coordinates thereof whether the vertical ruled line is added or the horizontal ruled line is added. If vertical ruled lines are added, all the vertical ruled lines connected to it are taken out from the vertical ruled line table CTB, set as one, and the horizontal ruled line that intersects the ruled line is searched from the horizontal ruled line table RTB, and the created vertical ruled line is created. Divide and register in vertical ruled line table CTB. Add horizontal ruled lines in the same manner. When deleting a ruled line, the point on the ruled line to be deleted is designated, and the device searches the ruled line table CTB, RTB for the designated ruled line from the coordinate and deletes it. If it is a vertical ruled line that has been deleted, all horizontal ruled lines that intersect with the vertical ruled line are fetched from the horizontal ruled line table RTB, the connected ones are integrated, and then the vertical ruled line table CTB is searched again and divided. And register again in the table. When the addition and deletion of ruled lines are completed as described above, step 6 in FIG.
By performing the processing from -4, a document having a table as shown in FIG. 7 can be output as shown in FIG.

Further, a case of handling a document having a table without ruled lines as shown in FIG. 8 will be described.

In the process of FIG. 4, such a document is processed as a table having no table in the process of step 6-1.

Therefore, in this case, the operator gives an instruction to display this page similarly to the word processor, and designates the frame of the table by the pointing device 9 by designating the upper left and lower right points thereof. In the following, the process of adding and deleting ruled lines may be performed as in the case of FIG. In this way, the eighth
A table having no ruled lines as shown in the figure can also be output as shown in FIG.

Since the tables CTB and RTB are as shown in FIG. 5, in addition to obtaining the output as shown in FIG. 6, the attribute of the ruled line is specified to change the ruled line type such as the back ruled line. It is possible to specify not to print the ruled lines, to change the size and typeface of the characters in a certain cell, or to make them vertically set, and to save them as they are.

In other words, by handling the frame defined by the cell table CELL as one column, it is possible to edit and typeset the document while maintaining the appearance of the document table created with a fixed pitch such as a word processor. it can.

〔The invention's effect〕

As described above, according to the present invention, by designating a desired area in the displayed document information, the characters displayed in the area are displayed as ruled lines corresponding to the area. Since the data is output to the enclosed area, it is possible to arrange the characters in the table at the same time as creating the table having the structure indicated on the display.
