Abstract

PURPOSE:To easily operate graphic input editing well balanced with the text by displaying a grid having lattice intervals depending on a text format on a screen, rounding and correcting while rounding a coordinate value designated by a user within an error range depending on this grid. CONSTITUTION:The contents of sentences displayed on the editing picture of a display device 5 are divided into areas at need and the number of areas and the information of those areas on a display screen are transmitted. Then, the detected area information is successively received, format information required for preparing the grid of received area is read out, and lattice line information for displaying the lattice lines of the grid is calculated. The coordinates of the start and end points of the calculated lattice line of the grid are successively transmitted to a RAM 3 and stored by areas, and this processing is repeated for all the areas on the screen. As a result, in the case of a display picture example including two areas, the lattice line information is stored in the RAM 3. Then, the coordinates of the start and end points of the stored lattice line information are successively read from the RAM 3 and plotted on the screen by dotted lines, and the lattice line of the grid is displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for creating and editing documents such as WP, DTP, and document processing software on a personal computer.

[0002]

2. Description of the Related Art Conventionally, when a document in which characters and figures are mixed is created by a word processor, a DTP (desktop publishing) system, etc., characters are input by a keyboard to create a text and a pointing device such as a mouse is used. A part of the text is surrounded by a figure, or a picture is drawn in the empty part of the text to finish the desired document. Further, when a pointing device is used for graphic processing, the work of performing an input editing operation while accurately instructing one dot corresponding to the resolution of the display device is burdensome, and therefore JP-A-62-251980 discloses. A grid-like grid called a grid as described is displayed by dotted lines, broken lines, etc., and the user's inaccurate point indication is corrected by rounding the input coordinate values based on the grid pitch of the grid. It assists the input editing operation.

[0003]

However, when inputting a figure on the text already written in a document in which characters and figures are mixed, the user often wants to input the figure on the basis of the already-input characters. . In other words, for example, when a group of characters is surrounded by a figure with a certain pattern, such as when creating a flowchart, a grid that is completely unrelated to the size and display position of the group of characters is displayed, and the input coordinate values of the figure are corrected And it is difficult to balance the shapes. Eventually, input editing is performed by point instruction in dot units, which deteriorates operability.

[0004]

This apparatus comprises means for detecting an area in which characters have already been input on an editing screen for graphic input editing, and means for dividing the area into document formats.
By providing a means for calculating and displaying the grid lines of the grid for each of the divided areas and a means for correcting the input value of the user according to the displayed grid, it is easy to input a figure dependent on characters such as a character frame. is doing.

[0005]

[Function] By displaying a grid having a grid interval depending on the text format on the screen for inputting and editing a figure and correcting the coordinate value specified by the user within the error range depending on the grid interval to correct the balance with the text. It becomes possible to easily input the figure.

1 is a block diagram of an apparatus showing an embodiment of the present invention. This apparatus includes a processor unit 1, a ROM 2 in which a system control program, a dictionary, character fonts, etc. are stored, and a RAM serving as a program work area.
3, a storage device 4 such as a hard disk or a floppy disk for storing document data or overwriting data, a display unit 5 including a display memory such as a text RAM for displaying characters and a graphic RAM for displaying graphics and a controller for displaying
And a display device 6 such as a CRT display and a liquid crystal screen, and an input device such as a keyboard 7 and a tablet 8.
FIG. 2 is a flowchart of the character corresponding grid program stored in the ROM 2. The character corresponding grid program is started as needed from the main program for creating and editing figures. That is, every time the display character configuration of the screen is changed by scrolling the screen or turning the page, the graphic input editing program calls the character corresponding grid creating program to create and display the grid.

FIG. 3A shows an example of a body text information format stored in the RAM 3, and FIG. 3B shows a display example of the body text information. When the input of the text as shown in FIG. 3B is completed, the graphic input edit mode is set, the grid corresponding to characters is created and displayed, and graphic input is performed to complete the document as shown in FIG. Hereinafter, the operation of the apparatus will be described by taking as an example the case where a grid corresponding to characters is created and displayed from the state where the text of FIG. 3 has already been input and a part of the text is displayed on the display device.

When the user specifies the character grid setting during input / edit of a figure, the program of FIG. 2 is started. First, in step 1000, the text displayed on the edit screen is divided into areas as necessary. That is, when creating a grid corresponding to characters, if the layout state of characters changes, the grid spacing of the grid also changes,
The whole screen does not always have a uniform grid like a normal grid. In this device, the area where the format such as the line pitch and the character pitch is changed is detected and the area is divided. Then, the number of areas and the area information on the display screen are sent to step 1001. The area information is represented by the coordinate values of the two diagonal end points of a rectangular area including characters of the same format on the display screen. This coordinate value depends on the screen size and resolution of the display device. Figure 3
In the sentence example of FIG. 5, since two types of document formats are included as shown in FIG. 5, for example, if a part of the document including the boundary of the formats is displayed as shown in FIG.
The number of areas sent from to 1001 becomes 2. Further, the coordinate values at the upper left and lower right of each rectangular area become area information. In this device, an area is created on the assumption that non-displayed characters are input even in a part that looks like a blank due to spaces, tabs, line breaks, etc.

Steps 1001 to 1003
Then, the information for displaying the grid is obtained for the separated areas.

In step 1001, step 1000
The area information detected in step S1 is sequentially received, the format information necessary for creating the grid of the received area is read, and the value is sent to step 1002. The format information necessary for creating the grid is vertical writing, horizontal writing, character pitch, and line pitch.
The character pitch is the distance between the display position base point of one character and the display position base point of the next character when entering the text. The line pitch is the distance between the display position base point of a certain line and the display position base point of the next line. Also, when the scaling of characters such as double-width, double-width, and half-width can be specified by the format, the magnification of the smallest character in the area is also read. That is, since the area 1 in FIG. 6 has two types of double-width characters (one in the line direction and twice in the character direction) and two-byte characters (one in the line direction and one in the character direction), the minimum character magnification Is 1 time in the line direction and 1 time in the character direction.

In step 1002, grid line information for displaying grid lines of the grid is calculated. In the case of the present apparatus, the grid line information is a list of the coordinates of the start point and the end point of each grid line segment in the vertical and horizontal directions when the screen is the xy coordinate plane with the upper left vertex as the origin. The grid of the grid is set so that the grid lines of the grid pass through the midpoints between the characters. That is,
For horizontal writing, the vertical grid lines have a line pitch interval and the horizontal grid lines have a character pitch space, and for vertical writing, the vertical grid lines have a character pitch space and the horizontal grid lines have a line pitch space. Step 100
2 sequentially obtains the grid line information of the start and end coordinates of the first horizontal line, the start and end coordinates of the second horizontal line, and sends the grid line information to step 1003. For example, if the format information is area information = upper left (xa, ya) lower right (xb, yb) character pitch = mp line pitch = gp minimum character magnification = line direction s times, character direction t times, the document is written horizontally. At this time, the Kth horizontal line from the top and the Lth vertical line from the right in the format of FIG. 5 are the Kth horizontal line. Starting point = (xa, gp × (K−1) × s) End point = (xb, gp × (K− 1) × s) L-th vertical line Start point = (mp × (L−1) × t, ya) End point = (mp × (L−1) × t, yb)

When the document is written vertically, mp in the above equation is gp
Then, the grid line is calculated by the calculation formula in which gp is replaced with mp.

The calculated coordinates of the start point and the end point of the grid line of the grid are sequentially sent to the RAM 3 in step 1003 and stored for each area.

In step 1004, the processes of steps 1001 and 1003 are repeated for all the areas on the screen. As a result, in the case of the display screen example of FIG. 6 including two areas, the grid line information as shown in FIG. 7 is stored in the RAM 3.

In step 1005, the coordinates of the starting point and the ending point of the grid line information stored in the RAM 3 are sequentially read out and drawn on the screen as dotted lines to display the grid lines of the grid.
As a result, the grid shown in FIG. 6 can be displayed. The user points with this pen on the displayed grid with a pen or mouse. Steps 1000 to 1 above
By repeating 005 every time the state of the display document on the screen is changed, the grid corresponding to the character can be always displayed.

The grid line information of FIG. 7 serves as a reference value for rounding and correcting the coordinate value pointed by the user. That is, when the user specifies one point (xu, yu) having coordinates on the display screen when inputting and editing a figure, x of the vertical grid line in FIG.
Of the coordinate values, the value closest to xu is searched, and the searched value is the x coordinate of the correction value, and y is the y coordinate value of the horizontal grid line.
The user input value is rounded using the value closest to u as the y coordinate of the correction value. That is, even if the user points the intersection incorrectly, the coordinates of the intersection of the closest grid are input.

FIG. 8 is an example of another type of grid. In the case of the format shown in FIG. 8, the grid line passes through four points around the character. In this form, the lattice spacing is irregular. That is, the lattice spacing changes depending on the ratio of the character size to the character pitch and the line pitch. Therefore, step 1000
Then, in addition to the character pitch and line pitch, the area is divided even in the part where the character size at the time of display changes. Since not only the original character size but also the part for which the double-width or half-width enlargement / reduction modification is designated becomes a separate region, the number of regions increases compared to the case of the format of FIG. 8 shows the same part as FIG. 6, but there is a double-width character in the area 1 in FIG. 6, so that part becomes a different area, and different grids are displayed in a total of three areas. Will be.

The horizontal and vertical lines in the format of FIG. 8 have different calculation formulas depending on whether the horizontal line is the upper line or the lower line of the character and the vertical line is the right line or the left line. Format information Area information = upper left (xa, ya) lower right (xb, yb) Character pitch = mp Line pitch = gp Full size character size (width, height) = (w, h) Minimum character magnification = line When the direction is s times and the character direction is t times, the K-th horizontal line from the top and the L-th vertical line from the right are the K-th horizontal line (K is an odd number) depending on whether K or L is an even-numbered or odd-numbered line. xa, gp × (K−1) × s + (gp−h) × s /
2) End point = (xb, gp × (K−1) × s + (gp−h) × s /
2) (K is an even number) Start point = (xa, gp × (K−1) × s + (gp−h) × s /
2) End point = (xb, gp × (K−1) × s + (gp−h) × s /
2) Lth vertical line (L is an odd number) Start point = (mp * (L-1) * t + (mp-w) * t / 2, y
a) End point = (mp × (L−1) × t + (mp−w) × t / 2, y
b) (L is an even number) Start point = (mp × (L−1) × t + (mp−w) × t / 2, y
a) End point = (mp × (L−1) × t + (mp−w) × t / 2, y
Each is calculated by the formula of b). The storage format of the lattice information and the rounding value calculation method are the same as those in the format of FIG.

As described above, when drawing a figure on a sentence in which several formats are mixed, a grid corresponding to the size of the character is generated, and the user inputs and edits the figure corresponding to the character. Can assist in doing

[0020]

As described above, according to the present invention, when a figure is input on a text that has already been input, a grid having a grid interval depending on the text format on the screen is displayed and an error range depending on the grid is displayed. By rounding and correcting the coordinate value specified by the user, the operation of figure input editing balanced with the text becomes easy.
