Abstract

PROBLEM TO BE SOLVED: To eliminate the need to correct document contents by adjusting the size of a block of a reference character string, repeating a layout process, and guaranteeing the adequacy of a page number that the reference character string indicates and a page number where a reference object appears. SOLUTION: Data are inputted through an input means 1 and a means 2 inserts the part of the reference character string in the document into the document as a blank character string. A page layout means 4 lays out the document. The result is stored in a storage device 3, and the block size of the blank character string is stored in the storage device 3. A reference position acquiring means 5 acquires the appearance position of a reference object, and a reference character string inserting means 2 generates the character string of a reference part. The page layout means 4 lays out the document again, and a number adequacy guaranteeing means 6 compares the result and regenerates the character string when the page that the reference character string indicates is different from the page where the reference object appears, and when they become equal to each other, a display means 7 displays the document on the screen or prints it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a layout processing method and apparatus using inter-element reference, and more particularly to assuring the validity of a number in a part referring to a page and reducing the burden on a user. The present invention relates to a layout processing method and apparatus using inter-element reference which enables the processing.

[0002]

2. Description of the Related Art SGML (Standard) is a document format suitable for automatically generating a table of contents, an index, and the like from a document and performing processing such as display and printing together with the original document.
Generalized Markup Langu
age) and other structured documents.

[0003] In SGML which is a structured document, layout information is not described in the document itself, and a document called "tag" is provided for each document element (for example, title, date, report destination, etc. in a report). Symbols are used to identify elements.

Tags include a start tag (described as "<element name>") indicating the start of a document element and an end tag (described as "</ element name>") indicating the end of the document element. Write the document element between the tags.

[0005] SGML is a document type definition (DTD: Document Type Define) in addition to a document.
) is required, and the definition of the tag and the definition of the document structure in the DTD (for example, the date appears only once in a report, etc.). , Etc.) are described.

[0006] SGML requires an SGML declaration in addition to the above-described document and DTD. The SGML declaration includes a maximum number of characters such as codes and element names used in the document, and "<>".
Is described as a tag. These documents,
The three elements of the DTD and the SGML declaration are the components of the SGML.

[0007] As described above, an SGML document is a list of tagged document elements, and does not describe any layout information, character size, and the like. A document processing device or the like is required.

In a document processing apparatus that lays out an SGML document and prints or displays it, when creating a table of contents or an index, the document is laid out once and “chapter” or “section” which is a component of the table of contents is created. , Etc., and a page in which a character string as a component of an index appears, and layout is performed again based on this information.

By using the same method, it is possible to refer to an appearance page such as a figure in the text.

However, when a reference character string is inserted into the text, the page layout after the location where the reference character string is inserted changes depending on the length of the reference character string, and the page where the reference object exists changes. Sometimes.

FIG. 7 shows an example of a document layout result using a conventional layout reference.

In FIG. 7, pages 51-1 through 51-
Reference numeral 4 denotes a state in which the first layout has been completed. The reference character string “see FIG. 1 page” is on page 51-1 (page 85), and the reference object “FIG.
(Page 99).

Pages 52-1 through 52-4 show the result of the layout performed again in consideration of the fact that the reference object "FIG. 1" is laid out on "99 pages". Has been replaced by "See Figure 1 on page 99".

However, on page 52-1, the reference character string "see page 99 of FIG. 1" is longer than "see page 1 of FIG. 1," so that page 52-1 (page 85) and page 52-2. (86 pages), and as a result, the reference object “FIG.
-4 (hundred pages), the page number of the reference character string differs from the page where the reference object appears.

For this reason, when the layout is performed again, as shown in pages 53-1 to 53-4, the reference character string "FIG.
The page "See page 99" is replaced with "See page 100 in Fig. 1."
Reference page "Figure 1" is again shorter than page 53-3 (page 99).
Is laid out.

As a result, since the page number of the reference character string is different from the appearance page of the reference object, the layout is performed again.

The document processing apparatus repeats the above-described processing, but cannot obtain a correct result forever and cannot determine a reference character string.

As a system that performs such a layout reference process, there is a document processing system called "TeX" for scientific papers. In "TeX", the page number indicated by the reference character string and the reference object No action is taken when the page that appears differs.

[0019]

As described above, when the reference character string cannot be determined, if the page number indicated by the reference character string is different from the page number where the reference object appears, it is left as it is. However, it is necessary to end the layout as a document having a defect or to manually change the position of the reference object by the user and perform the layout again.

Therefore, according to the present invention, the layout is performed so that the page number indicated by the reference character string matches the page number where the reference object appears, and the inter-element reference that does not require the user to modify the contents of the document is used. It is an object of the present invention to provide a layout processing method and apparatus which are provided.

[0021]

In order to achieve the above-mentioned object, the present invention provides a layout processing method using inter-element reference for generating a reference character string based on a page number on which a referenced object is laid out. When the page on which the object is laid out moves due to a reduction in the size of the block of the reference character string as a result of the relayout, the size of the block of the reference character string is changed to the size before the relayout is performed. And the layout is performed again, and the page number indicated by the reference character string matches the page number on which the object is laid out.

Here, when the reference character string is inserted at a plurality of positions, the size of the block of the reference character string in the reference character string is reduced to move the page of the object. The layout may be configured so that only the block size of the reference character string is held at the size before the re-layout and the layout is performed again.

Further, a blank in the document generated by performing the layout again while maintaining the size of the block of the reference character string at the size before the re-layout is performed. It can be configured so that it is laid out at a place where it changes.

According to the present invention, in a layout processing apparatus utilizing inter-element reference for generating a reference character string based on a page number on which a referenced object is laid out, the size of the block of the reference character string is re-laid out. Means for performing the layout again while maintaining the size before performing, and means for ensuring that the page number indicated by the reference character string matches the page number on which the object is laid out. .

Here, when the reference character string is inserted at a plurality of positions, the page of the object is moved by reducing the size of the block of the reference character string in the reference character string. The layout may be configured so that only the block size of the reference character string is held at the size before the re-layout and the layout is performed again.

[0026] Further, the size of the block of the reference character string is held at the size before the re-layout and the layout is performed again. It can be configured to have a means for laying out at a place where it changes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a layout processing method and apparatus utilizing inter-element reference according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing an embodiment of a layout processing method and apparatus using inter-element reference according to the present invention.

FIGS. 2 to 4 are flow charts showing the flow of layout processing in the embodiment shown in FIG.

In FIG. 1, a layout processing device 10
Are input means 1 for obtaining necessary data from a keyboard or a file, etc .; reference character string inserting means 2 for inserting a reference character string into a document; a storage device 3 such as a magnetic disk, an optical disk, a magnetic tape, and a memory; Page layout means 4 for laying out a document based on data, reference position obtaining means 5 for obtaining the appearance position of a reference object from a document, and checking whether the page number indicated in the reference character string matches the page where the reference object appears. It comprises a number validity assurance means 6 for assuring, and a display means 7 for displaying or printing a laid out document on a screen.

Here, the flow of the layout processing will be described with reference to the flowchart shown in FIG.

When the layout process is started (step 101), necessary data such as document data is input by the input means 1. The reference character string insertion unit 2 inserts the reference character string portion in the input document into the document as an empty character string (step 102).

Next, the document is laid out by the page layout means 4, the layout result is stored in the storage device 3, and the block size of the empty character string is stored in the storage device 3 (step 103).

The reference position acquiring means 5 acquires the appearance position of the reference object from the layout result stored in the storage device 3, and the reference character string inserting means 2 generates the character string of the reference part (step 104).

When the character string of the reference portion is generated, the page layout means 4 performs layout again (step 10).
5) The result of the relayout is compared by the number validity assurance means 6, and if the page indicated by the reference character string is different from the page where the reference object appears (N in step 106)
O) Regenerate the different character string (step 10)
7) Repeat the layout (step 105) and subsequent steps.

As a result of the re-layout, if the page indicated by the reference character string is equal to the page where the reference object appears (YES in step 106), the layout processing is terminated (step 108), and the layout result is displayed by the display means 7. Displayed or printed on screen.

FIG. 3 is a flowchart showing the flow of the relayout process in step 105 shown in FIG.

When the re-layout is started to properly represent the reference number (step 201), the reference character string is first laid out (step 20).
2). At this time, the number indicated by the reference character string is the page number where the reference object obtained as a result of the previous layout appears.

From the result of the re-layout, the size of the block of the reference character string is compared with the size of the reference character string when the previous layout was performed (steps 203 and 204).

If the comparison results are equal (NO in step 203, NO in step 204), the processing of the next reference character string is performed (YES in step 206).

As a result of the re-layout, if the size of the block of the reference character string is larger than the size of the reference character string in the previous layout (NO in step 203,
(YES in step 204) The layout after the reference character string insertion position is performed, and the processing of the next reference character string is performed (YES in step 206).

As a result of the re-layout, if the size of the block of the reference character string is smaller than the size of the reference character string at the time of the previous layout (YES in step 203), the monitoring mode layout described later is changed. (Step 207), if the monitoring mode layout ends normally (YES in step 208), the process of the next reference character string is performed (YES in step 206), and if the monitoring mode layout ends abnormally (NO in step 208). ) The size of the block of the reference character string is returned to the previous size, and the layout after the reference character string insertion position is performed (step 209).
The next reference character string is processed (YE in step 206).
S).

When the above processing is completed for all the reference character strings (NO in step 206), the relayout processing ends, and the flow proceeds to the processing in step 106 in FIG.

FIG. 4 is a flowchart showing the flow of the monitoring mode layout process. When the monitoring mode layout is started (Step 301), the layout is performed with the logical content next to the logical content in which the reference character string is inserted (Step 302) as the layout target (Step 303).

If the layout object is a reference object (YES in step 304) and the page is laid out on a page different from the previous layout result (NO in step 307), the monitoring mode layout ends abnormally (step 308). .

Also, when the layout target is a reference object (YES in step 304) and the layout is laid out on the same page as the previous layout result (YES in step 307), the layout target is not a reference object (NO in step 304). ), The same processing is repeated for all logical contents (Y in step 305).
If all the logical contents are completed (ES, step 302 and subsequent steps) (NO in step 305), the monitoring mode layout ends normally (step 306).

FIGS. 5 and 6 show examples of the processing results of the layout processing in the embodiment shown in FIG. 1. FIG. 5 shows a case where only one reference character string is inserted, and FIG. FIG. 11 is a diagram illustrating an example of a layout processing result when a character string is inserted at a plurality of positions.

In FIG. 5, pages 11-1 to 11-
Reference numeral 4 denotes a state in which the first layout has been completed. The reference character string “see page 1” is on page 11-1 (page 85), and the reference object “FIG. 1” is on page 11-3.
(Page 99).

Pages 12-1 to 12-4 show the result of the layout performed again in consideration of the fact that the reference object "FIG. 1" is laid out on "99th page". Has been replaced by "See Figure 1 on page 99".

However, on page 12-1, the reference character string "see page 99 of FIG. 1" is longer than "see page 1 of FIG. 1," so that page 12-1 (page 85) and page 12-2 (86 pages), and as a result, the reference object “FIG.
-4 (hundred pages), the page number of the reference character string differs from the page where the reference object appears.

For this reason, when the layout is performed again, as shown in pages 13-1 to 13-4, the reference character string "FIG.
"See page 99" has been replaced by "See page 100 in Figure 1."
See page 99.

When the layout after the shortened reference character string is laid out normally, the page number of the reference character string and the appearance page of the reference object remain different forever as shown in the conventional example.

Therefore, the layout of the blocks of the reference character string is performed like the pages 13-1 and 13-2 while maintaining the same size as the pages 12-1 and 12-2. In this case, the layout cannot be determined unless there is a blank at the top of the page 13-2, and a blank remains in the worst case.

However, this blank is shown in FIG.
By arranging the documents in a well-balanced manner at the top and bottom of the document and at the places where the paragraphs of the document change, the document can be laid out with a natural finish.

In FIG. 6, pages 21-1 to 21-
4 shows a state in which the first layout has been completed, and the reference character string “see FIG. 1 page” is added to page 21-1 (page 85) and page 21-2 (page 86), and the reference object “FIG. On page 21-3 (page 99)
It is laid out.

Pages 22-1 to 22-4 show the result of the layout performed again in consideration of the fact that the reference object "FIG. 1" is laid out on "99th page". And the reference character string “see FIG. 1 page” on page 21-2 has been replaced with “see FIG. 1 page 99”.

However, since the reference character string "see page 99 in FIG. 1" is longer than "see page in FIG. 1," the reference object "FIG. 1" is laid out on page 22-4 (hundred pages). That is, the page number of the reference character string is different from the page where the reference object appears.

Here, as in the example shown in FIG.
When the reference character string “see page 99 of FIG. 1” is reduced to “see page 100 of FIG. 1” while the size of the block of the reference character strings 2-1 and 22-2 is fixed, page 23
Both -1 and 23-2 are blank.

In the case of this example, the reference object “FIG. 1”
Is laid out on page 22-4 (hundred pages) because of the reference character string of page 22-1 (see FIG. 1, page 99), the size of the block of the reference character string on page 22-2 is changed. Even if the page is shrunk, the appearance page of the reference object “FIG. 1” does not change as shown in page 24-4, and there is only one blank space on page 24-1.

As described above, when there are a plurality of reference character strings and the reference character strings are shortened, if the size of the block of the reference character strings is unconditionally reduced, a plurality of blanks are generated. Can determine the layout by making only one blank.

In the above-described embodiment, reference is made between elements in a figure, and a reference object refers to the figure. A character string indicates a page in which the figure appears. In the method and the apparatus, a reference object can be arbitrarily specified, including a table, an expression, a character string, and the like.

[0062]

As described above, according to the present invention,
By adjusting the size of the block of the reference character string and repeating the layout, the validity of the page number indicated by the reference character string and the page number where the reference object appears is guaranteed, so that the user can check the reference character string. Or manually adjust the layout.
