Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device, and more particularly to a character processing device that supports easy layout editing processing in which text, figures, tables, and images are mixed.

[Prior Art] In conventional character processing devices, the control range when performing layout editing processing is generally limited to one page (see FIG. 2). 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, key actions such as page breaks are required to perform layout editing processing over several pages.

[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, so it is necessary to memorize some page layout. I needed the means. Character processing devices without such storage means often rely on the user's ability to store images.

Furthermore, in the above-mentioned character processing device, it is extremely inconvenient to edit the layout across pages.

For example, when moving the image frame from the layout shown in Figure 2 to page 2, if you specify the image frame and then perform the cut process (see Figure 3), the layout structure of the 1-page document will be clearly changed. It's getting worse. Next, specify the page,
Display the 2-page layout (see Figure 4 of the book). Specify the location where the cut image is to be pasted and perform the paste process (see Figure 5). After completing the series of work from FIG. 2 to FIG. 5, return to the first page where the layout composition has deteriorated and try to reorganize the layout. This kind of flow is
It was conventional layout editing.

The present invention was made in view of the above circumstances, and it is possible to
By displaying all document files, layout editing processing that spans pages can be easily performed.

[Means for Solving the Problems (and Effects)] According to the invention, when the activation means 100 shown in FIG. 1 is operated to display a layout, all one document file stored in the document storage means is Hey, layout development method 1
10, and the layout of the document is output to the display means 120 (see FIG. 7). At this time, in order to make the layout image as small as possible, the text part is not displayed. For example, if one character on the text screen is composed of 24 x 24 dots, the character position is
Indicated by dots. That is, the line column position of the page where the character exists is indicated by dot coordinates, and the coordinate value is set to OFF so that it is not displayed on the screen. On the other hand, if it is a part other than text (for example, an image, table, figure, etc.), it is displayed on the screen using 24×24 dots as a constituent unit and turning on the dot coordinate value of the line column position of the page where it exists. Then, each dot coordinate value is made to correspond relatively to the page, line, and column of the actual text. The above processing is performed in the layout development stage 110.

Next, when the layout control starting means 140 is operated in order to perform layout editing processing such as moving and copying, the layout control means 150 moves and copies each window, and the display means 120 is output (see Figure 8).

Furthermore, after converting the dot coordinates into page/line/column information by the document format conversion step 160, the original document storage means 130
Store in.

FIG. 10 shows the format of the document stored in the text buffer. The index section of the general structure of the document memory stores the start address of the line management information section, the start address of the text section, and the start 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, 9 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. In the layout data coordinate section, know the position where the actual data will be pasted in the document,
Paste the data in the layout data section at that position.

When the document structure is like this, the control flow of the present invention is
1 (a), (b), and (c).

In FIG. 6, when layout editing is selected from the pull-down menu, the control program according to the present invention is activated by key determination at S3 in FIG. 11(a). At S5, the size of the large block shown in FIG. 7 is calculated. This is a part that is affected by the display dot size of the character processing device. For example, the maximum number of dots that can be used for layout display is 500 x 900 dots, and the format is 60 dots per page.
If the line is set to 70 columns, the vertical (y coordinate in the figure) size is 5.
00+60-8 pages (480 dots), therefore, the size of one block can be set to approximately 480×70. Furthermore, if the inter-block size is 30 dots, the horizontal size (X coordinate in the figure) is 70+30, so 900÷100.
A maximum of nine 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 cn[ is smaller than the total number of bytes of the current line in S9, it is checked in S17 whether the current x, y coordinates fit within the current large block. If it is settled, read 1 byte of data in the text part indicated by the current pointer, and check 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 digits 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 Sit, and the pointer to the text portion and the total number of bytes of the current line are updated. Furthermore, in S15, the y coordinate is incremented and the X coordinate is returned to the start coordinate. Also, counter c
nt is cleared.

Now, if it is determined in S17 that the coordinates do not fit within the current large block coordinate range, then in S19 the coordinate system is moved to the next large block coordinate system obtained in s5.

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

After such control, the completed layout screen is transferred to the seventh screen.
As shown in the figure.

Now, FIGS. 11(b) and 11(c) show the control flow when the image data at the mouse cursor position of the second large block in FIG. 7 is moved to the first large block. Moreover, the layout screen after the movement is shown in FIG.

In Figure 7, click Cut on the menu bar with the mouse,
Next, when you move the mouse cursor to the image data of the second large block and click the mouse, the image shown in Fig. 11(b)
Flow control begins as shown in .

Since the dot at the mouse cursor position is ON in S105, the start coordinates, end coordinates, and current position coordinates of the image data at the mouse cursor position are calculated and saved in S107. Since the dots in the image data part are ON, calculations can be made by scanning one dot at a time from the current position coordinates up, down, left and right until the dots become OFF. Furthermore, the line column on the text is calculated from the start and end coordinates. Since the first coordinates and the first page of the second large block have already been obtained in S107, the first row column of the image data can be obtained by taking the difference between the coordinates. In S109, a pointer to the text section of the image data is obtained from the line management information section, and the identification code of the image data is obtained by scanning the text section. Since cutting is currently being performed, the entire area from the start coordinates to the end coordinates, that is, the coordinate area of the image data, is cleared in S113 through S111. Furthermore, in s115, the identification control code of the image data in the text portion is deleted up to the last line of the image data. Then, the row management information section from the first row of the image data is updated. Furthermore, the layout data No. is known from the identification code of the image data, and the layout data coordinate section is cleared.

By the way, if the position of the mouse cursor in FIG. 7 is in the text area, that is, the dots are OFF, the process ends without performing the above conversion process based on the determination in s105. Furthermore, in the case of copy processing rather than cutting, the process ends without clearing the dots in the image data area, deleting the identification control code in the text area, or clearing the layout data coordinate area in the determination in S111.

After completing the above control, click the paste in Figure 8 with the mouse, move the mouse cursor to the part where the dot in the first block is OFF, and click the mouse.
The control shown in the flowchart of FIG. 11(C) begins.

In the key determination in S121, since it is a paste process, S12
Branching to step 3, the moving distance of the mouse cursor and the start and end coordinates of the area to paste the image data are determined. The moving distance is the coordinates of the mouse cursor at the time of cutting (S
(already obtained in step 107). Furthermore, the paste start and end coordinates are S1
It is calculated by adding the start coordinate or end coordinate of the image data obtained in step 07 and the movement distance described above. Next, in S125 and S127, it is checked whether the area can be pasted. In S125, it is checked whether there is no image data in the area to be pasted, and in S127, it is checked whether the area to be pasted is within a large block. If it cannot be pasted, the process ends at that point. If pasting is possible, in S129 all dots in the coordinate area determined in S123 are turned ON. S] In step 31, calculate the line column on the text from the start and end coordinates. Since you have already obtained the start coordinates and the start page of the first large block in step S7, calculate the difference between the coordinates of the pasted image data and If you do this, you can get the first line column of the pasted image data. The identification control code obtained in S109 is inserted into the text section indicated by the pointer to the text section of the line management information section corresponding to this line, and at the same time, the information in the line management information section is updated. This process is repeated until the last line of the image data. The row management information section of subsequent rows is newly updated by adding the code inserted above. Furthermore, a new row column is added to which the coordinate part of the layout data is also pasted.

FIG. 8 shows a layout display in which the image data has been moved in this manner.

In the above flow, the movement of image data does not affect other images, figures, and table data that exist after the movement coordinates. In other words, images, shapes,
Table data has been described on the assumption that only the data to be edited changes layout coordinates and line digits. However, the coordinates and line digits of text change as the data is moved or copied.

[Other Embodiments] Although the present invention has been described using an example in which the entire image frame is moved to a text position, it is also possible to move or copy a specific sentence of text.

For example, on a character processing device that can display in color, if you specify coordinate values such as red for the text section, blue for the image section, green for the graphic section, yellow for the front section, and white for the blank section, the text can be displayed in other places. When copying to the coordinates of , the blue, green, and yellow dots do not change their coordinate positions, and if you fill in the white part of the coordinates after the -copy position by the number of red dots copied, the type attribute is copied. This means that it has been completed. Further, in conjunction with the copying described above, the content of the document is changed by the coordinates affected by the copying.

Of course, there is a relative relationship between the coordinate position and the line position of the document, so the line position can be calculated from the coordinates.

[Effect of the invention] Conventionally, when moving or copying a figure located at the end of a document to the beginning of the document, the last page of the document was first specified, the screen was switched to the last page of the document, and the movement/copying was performed. Specify the figure you want to copy, specify the first page of the document, and switch the screen to the first page of the document. Then, when the screen changed, the general operation was to paste the graphic that underwent the above processing into the specified location. According to the present invention, editing such as moving and copying as described above can be processed on one screen, and operations can be simplified.
