Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document layout device for obtaining a desired document layout through a display such as a CRT, and is applied to word processors and the like.

[9, Ming J! [Summary] The present invention is a document layout device for a word processor or the like, and can be used to create text on a screen.

A document area to be moved is specified, this specified area is made into a moving image, and it is composed of display pattern information within the area and coordinate information of the area, and by changing this coordinate information from the outside, the specified area is moved on the display. Therefore, the layout of sentence 1g can be optimally adjusted between man-machines with good responsiveness.

[Prior Art] In the Bun.4 processing device, there is a function (Bun. 1!
It is desirable to have a layout If collection function).

In the prior art, two methods are known for this type of layout editing. In the first method, the user first specifies the range (start J'!) to which a table, graph, etc. is to be moved from within the document layout screen called up on the CRT, and then Specify the destination range, which is the land, and have the processing device execute it.In this case,
A processing bag is a sentence, which edits the document data that was at the starting point in the memory (transfer it to the destination and convert it into a sentence 1!),
Based on the results, change the display pattern and
The changed sentence+'T layout is displayed above.

In the second method, the user specifies the range to be moved, then moves that range using the cursor keys or joystick, and when the document layout screen is in the state desired by the user, the user completes the layout. Instruct. In this case, the processing device rewrites the contents of the document memory and display memory each time a movement instruction is input using a cursor key or the like.

[Problems to be Solved by the Invention] In the first conventional method, since the processing device only needs to perform the movement process once, it is considered that the desired layout can be obtained in a relatively short time. However, with this method, it is not possible to find the optimal destination by sequentially moving within a specific range while looking at the screen. In other words, only one destination can be selected at a time, so it is not possible to find the optimal destination He has a strong tendency to choose the wrong place. Furthermore, when the user moves to the selected destination, the layout screen is different from what the user expected, and there are many cases where the user has to select a new destination again.

On the other hand, the second method does not have the drawbacks of the first method, and by moving the range while looking at the screen, the user can find the destination that he or she deems optimal. However, the processing device must rewrite the document code string and the associated display pattern each time a movement instruction is issued for a specified range, which increases the amount of data processing. The display response to key human power will be poor. For example, 24 dots x 24
When moving the range of dots one dot at a time, the display pattern of 576 x 2 dots each time is ! ), and if the destination was found after moving 100 dots, a total of 115.200 dots would be required to be changed.

The present invention has been made in view of these points, and it
Second, it is an object of the present invention to provide a document layout device that can move the range to be moved with good responsiveness and allows a user to easily and freely adjust the layout of a document.

[Means for Solving the Problems] FIG. 1 is a functional block diagram of the present invention, and A indicates the display r-
B is a document data storage means, C is a screen data storage means for storing screen data for displaying the layout of sentences on the display means based on the contents of the document data storage means, and D is a display screen. Area specifying means for specifying the coordinate area above; E is moving image data storage means for storing data in the specified area among the data in the screen data storage means C; F is coordinate storage means for storing moving image coordinates; G is a coordinate updating means for updating the moving image coordinates, H is a display control means for displaying moving image data as 1ν view of screen data on the display stage A, ■ is a coordinate specifying means for fixing the moving image coordinates, and J is a coordinate specifying means I In response to this, the document data rewriting means UF writes the document data in the specified area in the document data storage means B into the area defined by the fixed moving image coordinates (destination coordinates).

[Sakukawa] The present invention will be explained in detail. Now, screen data storage means C
screen data based on the contents of document data storage means B (
It is assumed that the display pattern data (display pattern data) is stored, and the display means A displays the layout of the sentence JX according to this screen data. Here, the user specifies the area to be moved in the layout using the area specifying means. As a result, the data in the specified area among the data in the one-screen data storage means C is transferred to the video data storage means E, and the semi-coordinates of the designated area are used as the initial values of the video coordinates in the coordinate storage means. Stored by F. As a result, a moving image is defined by the moving image coordinates and moving image data, and a still image serving as the background of the moving image is defined by the screen data of the one-screen data storage means C on the display means A. here,
As the user moves the video coordinates through the coordinate update stage G, the display control means H transfers the video data to the display means A based on the updated video coordinate values. As a result,
In the display means A, the moving image screen moves across a background screen that is divided into one screen of data.

In the present invention, in order to bring about this result, there is no need to rewrite the video data or pattern at all.

All you have to do is redefine the video coordinates for the width. In other words, it is a method of placing a piece of paper with a string on top of a fixed piece of paper and pulling the paper with the string to move it over the fixed piece of paper. There is no need to erase what is being drawn; therefore, the display response to pulling a string (analogous to a video coordinate updating means) is good, and the user can instantly see the state of the document layout at various candidate target locations. You can easily find the optimal document layout.

When the document layout is in a desired state, the user instructs completion of the layout via the coordinate specifying means I. As a result, the moving image coordinates are fixed, and the document data rewriting means J transfers the document data in the specified area in the document data storage means B to the destination area determined by the fixed coordinates of the moving image. Create the document data that will be the basis for obtaining Bartkovy.

[Example] Hereinafter, one embodiment of the present invention will be described in detail.

Structure 1 The overall structure of this embodiment is shown in FIG. 1. Equipped with left, right, up and down cursor keys used to move the moving image and specify ranges, and an execution key 1-3 used to instruct the machine to execute processing.

Reference numeral 2 denotes a CPU that controls the entire apparatus, and controls the key human power section 1, various peripheral devices, and memory.

Reference numeral 3 denotes a document memory that stores document data edited via the CPU 2 in code format.

Reference numeral 4 denotes a save memory used to save document data in an area to be moved out of the document to be laid out. After the destination is determined, the contents of the save memory 4 are inserted into the destination in the document memory 3 via the CPU 2.

5 is a video controller with a built-in processor;
It has a sprite function and sends a video signal to the display unit 7 (CRT in this case) based on the contents of the video memory 6 for display.

This display? In this example, the B7 screen consists of 767 patterns (blocks) in total, 32 in the column direction and 24 in the row direction (see Figure 3(a)), and each pattern block is 8 dots x 8 dots. Consists of 8 bytes. In addition, the layout display area is allocated to an area of 40 dots in the digit direction and 63 dots in the line direction from the left position (0, O) of screen -1-. , each character is displayed as one dot. Therefore, it is possible to display a dot-format layout of a document consisting of a maximum of 40 characters per line and 64 lines of characters.

The number of lines on the layout screen directly corresponds to the number of lines on the document memory 3, and the number of digits indicates how many digits of characters in the related line on the document memory 3.

The video memory 6 includes a screen block table 6-1, a video generator table 6-2, and a video attribute table 6.
-3.

As illustrated in FIG. 3(C), the screen block table 6-1 has 767 blocks of patterns (each of 8
Byte structure 1&,) is stored, and the al pattern is displayed at the relative address (8N to 8N+7) at the Nth block position on the screen.For example, screen block table 6-1. relative address 0-7
The 8-byte pattern in is the coordinate (0,0) on one screen.
, (7,0), (7,7) (0,7) (the block indicated by O).

As illustrated in FIG. 3(d), the video generator table 6-2 stores two 8-byte sprite patterns each.
Memorize 8 pieces. On the other hand, the video attribute table 6-3 stores 28 types of sprite attribute information, each of which is composed of 4 bytes. Each sprite attribute information is sprite's xp! It consists of the i mark, the Y coordinate (the upper left coordinate of the sprite pattern block displayed on the screen), the sprite number, and the color code. The pattern specified by the sprite number N is the pattern at relative addresses 8N to 8N+7 in the video generator table.

In FIG. 2, numeral 8 is a group of coordinate registers that store parameters used to change the document layout; The upper left register stores the upper left coordinates of the range specified diagonally to move from the layout screen (coordinates that determine the beginning of the display pattern to be actually moved), and the lower right register stores the coordinates of the upper left of the range specified diagonally to move from the layout screen. The coordinates below are stored. Additionally, the coordinates ■ upper left coordinate register contains the upper left coordinates of the screen block that contains the upper left coordinates of the specified range, and the coordinates ■ lower right coordinate register contains the screen block whose internal coordinates are the lower right coordinates of the specified range ( In other words, the lower right coordinates of the specified range (the lower right coordinates of the specified range are located inside this block) are stored. Coordinates■
The two types of coordinates, ``and'', are determined for convenience of processing, and the initial coordinates of the sprite block or moving image range are made to match the coordinates of the screen block. In addition, the document address register stores the address in the document memory 3 corresponding to the upper left coordinates of the movement specified range on the layout screen, and the document address register stores the address in the document memory 3 corresponding to the lower right coordinates of the movement specified range on the layout screen. It stores addresses.

In this example, the contents of both document address registers define the range from which data is to be deleted from the document memory 3.

Elbow-1 Next, the following. The operation of the embodiment configured as shown below will be explained using a specific example.

At present, the layout display section is called up on the display section 7, as shown in FIG. If the user wants to change the layout of the document, , First, press the movement key t-i. This enters the flow shown in FIG. 6, and as shown in step 31, the current cursor position on the layout display (color is green) is decremented, and then, A message is displayed on the message display section of the display section 7 asking the user to input the starting position of a specified range such as "From where?" (step S2). , and press the execution key (step S3). In response, in step S4, the coordinates (2) upper left register and the document address I register are set (see FIG. 4(b)).

Further, the upper left coordinate of the block (block 97 in the case of FIG. 4(b)) containing the upper left coordinate of the coordinate (2) is determined and stored in the upper left register of the coordinate (2) (step S5).

Next, the CPU 2 instructs the message display section of the display section 7 via the video controller 5 to input the last position of the designated range, such as "How far?" (step S6). , move the cursor to the last position (in the above example, the 26th character on the 41st line) and press the execution key (step S7).In contrast, the machine side performs the same procedure as step S4. , the coordinate ■lower right register and the document address register are set (step S8).

Further, in step S9, the coordinates of the upper left of the block (block 163 in the above example) having the lower right coordinates inside are determined and stored in the coordinates 2 lower right register.

By specifying the above range, the corresponding on-screen coordinates, block coordinates, and document address information are created. After that, the definition of the video screen and other operations are performed.

That is, in step SIO, the video screen is determined based on the screen block coordinates "left"; and the lower right coordinates, and the coordinates, sprite number, and color code (red) of each sprite are set in the video attribute table. To explain in more detail, the video controller 5 generates a screen block 97. which has a pattern as illustrated in FIG. 4(b), that is, a screen block 97.
98.99, 129, 130, 131.161.162
．． The contents of 163 are extracted from the screen block table 6-1, and the extracted pattern includes portions that do not actually move, as shown in the left-hand diagram of FIG. 4(b).

That is, the pattern to be actually moved is the pattern specified by the cursor, that is, the pattern defined by the upper left and lower right of the diagonal coordinates (■). Therefore, when reading each block from the screen block table 6-1.

All patterns outside the range to be actually moved are cleared. As a result, a moving image as shown in FIG. 4(C) is obtained. As you can see from this diagram, the top left diagonal coordinate is the coordinate of sprite 0, and the Y coordinate is +8
The larger one is the coordinate of sprite l, and the sprite coordinates and sprite number are stored in the video attribute table 6-
It is predicted to be 3. In addition, the color code for the video is set to red to provide a good contrast with the green of the still image. Further, in step Stt, the determined sprite pattern data of the moving image screen is set in the moving image generator table 6-2 by sprite number. As a result, data having a pattern as exemplified in FIG. As described above, the specified video screen data is displayed on the layout display section of the display section 7 as a screen superimposed on the screen defined by the screen data in the screen block table 6-1 (the video controller 5 When sending the video signal to section 7, the screen data in the same area as the video screen data is cleared and only the video data is passed).

On the other hand, in step S12, the document data within the range specified by the document addresses (2) and (2) is copied from the document memory 3 to the save memory 4. and.

In step 313, the document data in this area is deleted from the document memory 3.

Then, in step S14, the layout is displayed based on the contents of the document memory 3 after the deletion process.
U2 displays a message such as "Where?" on the message display section of the display section 7 via the video controller 5 (step 515).

In response, the user moves the video screen displayed in red on the layout display area to the left, right, up, or down using the cursor keys, thereby changing the coordinates and text of each sprite on video attribute table 6-3. -7, Address ■ The contents of the register are updated. Here, the video controller 5 does not change the sprite patterns that define the pattern of the moving image screen, but simply displays each sprite pattern on the display unit 7 as a video signal at the timing according to the update 1 of each sprite coordinate. Send. As a result, the video screen moves efficiently in the layout display section.

In step S17, it is checked whether the destination of the moving image screen has been determined by checking the presence or absence of the execution key.

When the user is satisfied with the layout on the layout display section, the user presses the execution key 1-3 to notify the machine that the layout changes and adjustments are complete (Fig. 5 (a) shows the result at this time. This is an example of the layout screen and the shape of the screen blocks around the video).

In response, the CPU 2 saves the document data saved in the save memory 4 as a sentence,! ; Insert into the document memory 3 and perform editing processing according to the contents indicated by the address I register (indicating the start address of the destination on the document memory 3).
Step 518), and the sentence after the editing process in step S19 -! ■The contents of the memory are displayed (followed by the layout display, and finally the video generator table 6-
2 and clear the video attribute table 6-3 (step 5
20). The final layout display and the state of the screen blocks are illustrated in FIG. 5(b).

As described above, in this embodiment, the document layerer I can be adjusted between man-machines with good responsiveness.

In addition, although multiple sprites are used in the example described in L, the coordinates are one, a block of any size is used as the video screen, and the video screen can be quickly moved on the display simply by rewriting the coordinates. In addition, in the above embodiment, one character corresponds to one dot on the layout screen, but the invention is not limited to this. For example, the full-scale sentence screen may be used as a layout screen for adjusting the layout of any sentence.

In addition, in the above embodiment, a certain area in the document is erased and moved to the target location, but this is not limited to 0. For example, data in a certain area in the document is moved to another location. The present invention can also be easily applied when copying to an area. This also belongs to changing the layout of a document in a broad sense.

[Effects of the Invention] As detailed above, in the present invention, the movement of blocks for adjusting and changing the document layout is controlled by coordinates, so the optimal document layout can be easily obtained in a short time. .
