It is designed to be displayed on a ray tube, etc.

(Problem to be Solved by the Invention) However, in such a conventional editing screen display method, every time the display of a specified editing area is changed, it is necessary to re-edit the display area other than the editing area. Because it was expanded and displayed as a bitmap image, if it contains data that requires time to process, such as images or graphs, the display time would be reduced if the entire display screen was expanded each time. This takes a very long time, and processing other than the original editing operation takes time, which hinders the efficiency of the editing process.

(Object of the Invention) Therefore, the present invention reduces the time it takes to change the display of the editing area by changing only the display within the editing area specified in the editing screen according to the editing command, and the editing screen The purpose of this paper is to provide an editing screen display method that speeds up layout editing and area editing.

(Structure of the Invention) In order to achieve the above object, the present invention develops input text data and image data into bit image data according to a predetermined input editing command, and displays the data as an editing screen on a screen such as a CRT. However, in the editing screen display method, the bit image data displayed on the editing screen specifies the editing area by the editing command, changes its display size and display position, and performs layering on the editing screen. , comprising an editing area storage means for storing bit image data of the editing area designated by the editing command as text data, and a control information storage means for storing area control information such as a position on the screen where the editing area is displayed, When the editing area is changed by the editing command,
The present invention is characterized in that only the text data and area control information stored in the editing area storage means and the control information storage means are changed and developed into bit image data, so that only the display of the editing area on the editing screen is changed. It is something.

Hereinafter, the present invention will be specifically explained based on examples.

1 to 6 are diagrams showing an embodiment of the present invention, which is applied to a personal computer with an editing function.

FIG. 1 is a block diagram of a personal computer 1, which includes a CPU 2, a mouse 3,

As shown in FIG. 2, the layout editing section 11 of the CPU,
It is composed of an expansion control section 12 and a bit image data expansion memory 13. The layout editing section 11 is composed of a character string editing section 14 and an area editing section 15, and specifies and develops text data necessary for editing the layout of the display screen being edited in accordance with editing commands input from the mouse 3 and keyboard 4. It has a function of instructing the bit image data storage memory 13 to develop the text data as bit image data via the control unit 12, and the character string editing unit 14 edits the text data outside the specified editing area. Exclusive processing is performed and the expansion control unit 12 is instructed to expand the text data subjected to exclusive processing. The area editing unit 15 instructs the expansion control unit 12 to expand the text data in the designated editing area.

The expansion control unit 12 includes a character string expansion unit 16, an area expansion unit 17,
It is composed of an area control information memory (control information storage means) 18 and an area data cache memory (editing area storage means) 19, and the character string expansion section 16 is connected to the character string editing section 1.
4, the text data other than the editing area is developed into the bit image data development memory 13. The area development unit 17 converts the text data of the specified editing area into bits based on the control information such as the display position and attributes (transparent/non-transparent) of the editing area stored in the area control information memory 18 or the area data cache memory 19. Image data deployment memo Will be deployed on January 3rd. Area control information memo January 8
Control information as shown in FIG. 3 is stored in the area data cache memory 19, and text data of an editing area having an ID number (a number uniquely assigned to each designated editing area) is stored in the area data cache memory 19.

The bit image data development memo In3 is developed into bit image data based on the text data transferred from the character string development section 16 and the area development section 17, and then outputted to the CRT5.
to be displayed.

Mouse 3 specifies the layout W collection area as an editing command,
The display position and the like are output to the layout editing section 11, and the keyboard 4 outputs the same editing commands as the mouse 3 as well as various editing commands and data shown in FIG. 4 regarding the editing contents.

The HDD 6 stores programs such as layout W collections and area editing, and document data, and the FDD 7 stores document data and the like.

Next, explain the action.

The present embodiment is characterized in that only the display contents of the editing area designated on the editing screen are changed in accordance with the editing command. The layout editing process for this editing area will be described below with reference to the flowchart shown in FIG. 5.6.

In this embodiment, processing accompanying a command to move an editing area specified in advance will be described.

When a command to move the editing area is input to the layout i collection unit 11 by the operator's operation of the mouse 3 or keyboard 4, the character string editing unit 14 executes exclusive processing of the text data accompanying the area movement, step P1), that is, , Recognizes text data outside the editing area, transfers the text data subjected to exclusive processing to the bit image data development memo January 3 via the character string development unit 16, and develops it into bit image data (Step P2) . Next, the area editing unit 15 processes the text data in the editing area according to the flowchart shown in FIG.
).

Now, moving to the flowchart in FIG. 6, the area editing section 15
First, check whether the text data of the designated area with the ID is stored in the area data cache memory 19 (step P11), and if it is not stored, the area control information memo 1 is moved based on the above movement command. Set the control information shown in FIG. 3 on month 8 (step P12). Then, according to the set control information C4, the text data of the specified area is developed on area data cache memo January 9. Step P13), area data cache memo The text data on Fugetsu 9 is transferred to the bit image data development memory 13, and the processing of the area editing section 15 is completed (step P14).

Also, step pH area data cache memo January 9
When the text data of the designated area is stored, this text data is transferred to the bit image data development memory 13 and the processing is completed.

Returning to FIG. 5 again, the layout i collection unit 11 develops the editing area developed in the bit image data development memory 13 and the bit image data other than the editing area into page image data after lifting (after moving the area), Based on this page image data, only the editing area within the editing screen being displayed on the CRT 55 is changed (step P4).

The above explanation is about the processing when moving the editing area, but
Even if partial initialization (see Figure 4) is specified as another command, other area data is not changed, so the minimum necessary editing area data is expanded in the bit image data expansion memory 13. Then, page image data is created. Also, ID is added to the editing area data.
By assigning a number and storing it in the area data cache memo January 9, the area data cache will be used for the area that has been expanded once in the expansion process of the formatted area common to each page and the previous/next item display process. Transferring and receiving data between the memory 19 and the bit image data expansion memory 13 (
data processing step in layout editing processing.

The number of layout processes can be reduced, and the processing speed of the entire layout process can be increased.

Therefore, by changing only the display content of the specified editing area in accordance with the editing command on the display screen during editing, it is possible to significantly reduce the time required to develop the bit image data of the editing area during layout editing. It is possible to speed up the editing operation time on the personal computer 1.

Although this embodiment shows a case where the editing screen display method of the present invention is applied to a personal computer, it is not limited to this, and can be applied to all devices that display an editing screen and perform editing processing, such as a word processor. Of course, it is applicable.

(Effects) According to the present invention, only the display within the specified editing area on the editing screen is changed according to the editing command.
By shortening the time required to change the display of the editing area, it is possible to speed up the editing of the layout and area on the editing screen.
