Abstract

PURPOSE:To easily execute the comparison of layout between respective pages by providing a display means for a sentence to be inputted from an input means, document storing means to store the sentence and layout developing means to transform the page, line and digit of the sentence to coordinate values for the unit of a dot according to format information. CONSTITUTION:An activating means 100 is operated for layout display, one file stored in the document storing means is wholly layout-developed by a layout developing means 110 and the layout of a document is outputted to a display means 120. The line and digit positions of the page, where characters are existent, are shown by dot coordinates and the dot is turned OFF not to be displayed by a picture. Reversely, in the case of a part excepting for the sentence, 24X24 dots are defined as the constitution unit and the dot coordinate values for the line and digit positions of the page, where the part is existent, are turned ON to be displayed by the picture. The respective dot coordinates are relatively made coincident with the page, line and digit of the real text. Thus, the whole constitution of one document file can be observed in one picture.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character processing device, and particularly when performing layout editing processing of a document containing a mixture of text, figures, tables, and images.
The present invention relates to a character processing device that facilitates processing by displaying a layout.

[Prior Art] For example, in conventional character processing devices, the display range when displaying the layout of a document is generally limited to one page of paper size, as shown in FIG. This is because, due to the relationship between the display screen size and the size of characters, images, figures, etc. displayed in the layout, the layout size that can be displayed at one time is limited to one page. Therefore, in order to view the layout of several pages, it was necessary to switch screens using key actions such as page break.

[Problem to be solved by the invention] However, in the above method, in order to know the layout relationship with other pages, it is necessary to change the screen by key action such as page break. needed a memory device. In character processing devices without a storage means as described above, in many cases the user's ability to memorize images is relied upon.

The present invention was made in view of the above-mentioned problems.
By displaying the layout of all document files, it is possible to easily compare the layouts of each page.

[Means for Solving the Problems (and Effects)] According to the present invention, when the activation means 100 of FIG. 1 is operated to display a layout, all one document file stored in the document storage means is , layout development means 11
0, and the layout of the document is output to the 1,000-column display 120 (see FIG. 3). At this time,
In order to make the layout image as small as possible, the text portion is not displayed. For example, on the text screen, 1 character is 2
If the configuration is 4×24 dots, each character is represented by one dot. That is, the line column position of the page where the character exists is indicated by dot coordinates, and the dot is turned off so that it is not displayed on the screen. Conversely, parts other than text (for example, images,
(tables, figures, etc.), use 24x24 dots as a constituent unit, and calculate the tot coordinate value of the line column position of the page where it exists.
Display on the screen as N. And the coordinates of each dot are
Match the pages, lines, and columns of the actual text relative to each other. The above processing is performed by the layout development means 110.

[Example] Hereinafter, the present invention will be explained in detail with reference to the drawings.

The microprocessor CPU reads various control signals stored in the ROM, and various controls are performed in accordance with these control signals.

FIG. 6 shows the format of documents stored in the text buffer. The index section of the general structure stores the starting address of the line management information section, the starting address of the text section, and the starting address of the layout data section. The line management information section stores information for managing text for each line of text, that is, a pointer to the text section for each line and the number of bytes for each line. In the text portion, character codes or control codes for identifying figures, tables, images, etc. are stored in continuous areas.

In the figure, the parts from * to * correspond to the above control code.

The layout data section stores layout data management information and layout data. The location where the actual data of the layout data section is stored is known from the control code of the text data. The layout data coordinate section determines the position where the actual data is to be pasted in the document, and the data in the layout data section is pasted at that position.

When the document structure is like this, the control flow of the present invention is
It is shown in the figure.

In FIG. 4, when layout editing is selected from the pull-down menu, the control program according to the present invention is activated by key determination at 33 in FIG. At S5, the size of the large block shown in FIG. 3 is calculated. This is a part that is affected by the display dot size of the character processing device. For example, if the maximum number of dots that can be used for layout display is 500 x 900 dots, and the format is set to 60 lines and 70 columns per page, the vertical (y coordinate in the figure) size is 500 ÷ 6.
0→8 pages (480 dots), therefore, the size of one block can be set to approximately 480×70. Further, if the inter-block size is 30 dots, the horizontal (X coordinate in the figure) size is 70+30, so 900÷100, and a maximum of 9 large blocks can be displayed at one time.

In S7, each parameter is initialized. That is, the start coordinate and end coordinate of each block are determined, and the current coordinate is set to (0, 0) as the upper left corner of the first block. Furthermore, by reading the line management information of the first line, the address of the first line of the text portion is known. If the text counter cnt is smaller than the total number of bytes of the current line in S9, the current x. Check whether the y coordinate fits within the current large block. If it is settled, read 1 byte of data in the text section indicated by the current pointer, and write S to determine whether the data is a character or a control code.
23 Check. The text pointer at this time can be obtained from the pointer to the text section of the current line in the line management information section and the counter cnt. Furthermore, after reading 1 byte of text data, the counter is incremented. If it is a character code in S23, one dot at the current coordinates is turned off in S27. If it is a control code, the coordinates up to the digit obtained from the coordinate management section of the layout data section are turned on in S25. Then, the X coordinate and the counter cnt are updated, and the process returns to S9.

In S9, if the text counter cnt becomes larger than the total number of bytes of the current line, the next line management information is read in Sll, and the pointer to the text part and the total number of bytes of the current line are updated. Furthermore, at 515, the y coordinate is incremented and the x coordinate is returned to the starting coordinate. Also, counter c
nt is cleared.

Now, if it is determined in S17 that the coordinates do not fall within the current large block coordinate range, then in S19 the coordinates are moved to the next large block coordinate form obtained in S5.

The above flow continues until there is no row management information left in S13.

[Other Examples] Although the above example ends in explaining the entire layout display of the entire document file, it can also be used to extract and display figures, tables, and images, or conversely, to extract and display specific sentences. It is possible.

For example, in the branch of S23 in FIG. 7, "Is the current data an image?" 1, and if it is an image, the dot at the x and y coordinates is turned on, and if it is not, the dot is turned off.

Then, when the layout of the entire document file is displayed, only the image portion is displayed (see FIG. 8).

Similarly, in the branch of S23, the question ``Is the current data a figure? ', and only the coordinate values of the figure part are O.
If set to N, only graphics can be displayed.

[Effect of the invention] Originally, it was common knowledge that the layout of a document was displayed on only one page, but it is now possible to convert the document into as small information as possible (thereby, the entire structure of one document file can be viewed on one screen). becomes.
