Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing system for editing and operating edit objects such as documents, figures and tables, and more particularly to a magnified display system in a document editing apparatus for magnifying and displaying the edit object.

[0002]

2. Description of the Related Art In a conventional document editing system, an enlargement display of an edit object is performed by a user command. For example, in a conventional method, in a technical document editing system which is application software, an enlargement command is used. There is a method of enlarging and displaying the designated area by designating the enlarged area after input.
FIG. 2 shows a conventional enlarged display processing procedure and an example of a display screen.
In the enlarged display flow chart, the user selects the enlargement command 24 displayed under the document edit screen 9 as the enlargement command input 16. Next, the user
As the enlargement area designation 17, the enlargement area 25 including the element to be edited on the editing screen 12 is designated. After the end of the above two user operations, the system performs an enlarged display process 18 so that the designated enlarged area is displayed on the entire screen. After enlarged display, the user can edit 2
6 is selected 19, edit command 27 is input 20, and edit 21 is started. When the screen is returned to the original state after the editing is completed, the user inputs the reduction command 22. As a result, the system side performs the reduced display processing 23 and returns the screen to the initial display state without the enlarged display.

[0003]

The conventional method has the following problems. In editing operations, the figure or table to be edited is often small, and it is usual to edit the element to be edited after enlarging the display. Therefore, the user
Requires frequent enlarging operations for enlarging and displaying an object to be edited during editing operations, which requires time and effort for editing. An object of the present invention is to reduce and simplify the editing operation by the user when the object to be edited is enlarged and edited on the display screen, and the editing is speeded up.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to obtain the size of an element to be edited at the time of inputting an edit command subsequent to the input of an element to be edited during an editing operation, and to calculate the size of the element. This is achieved by calculating the magnification for displaying the element to be edited on the entire screen based on the original size and displaying the enlarged image.

[0005]

The user can operate the edit command input to enlarge the display of the object to be edited. Therefore, the user can perform the enlargement command input and the enlargement area designation operation conventionally performed for the enlargement display. Can be omitted, and when editing, the editing operation of a technical document or the like, which has a large number of editing targets that need to be enlarged, can be reduced and simplified, and the editing can be speeded up.

[0006]

EXAMPLES Examples of the present invention will be described in detail below. FIG. 1 is a block diagram of the main body and screen of a document editing apparatus according to an embodiment of the present invention. In FIG. 1, 1 is a central processing unit for controlling the entire system, 2 is a main memory for running programs, 3 is an auxiliary memory for storing data, files, etc., 4 is a keyboard 6, mouse. An input / output controller 5 for controlling an input device such as 7 is a display controller 5 for controlling a display 8, and 8 is a display. A document edit screen such as 9 is displayed on the display 8, and a common command commonly used in each edit state and an edit menu for switching an edit target are displayed in a portion 10. Editing menu is shown in 11
The edit command corresponding to 10 is displayed. The document editing operation is performed by selecting these editing commands 11. An edit screen 12 that displays the document to be edited is displayed in the center of the screen.
In the edit screen 12, in addition to freely arranging characters, a graphic area 13 for arranging graphic elements, a character area 14 for arranging character elements, and a table element are provided. Table area 1 which is an area for arranging
5 can be placed.

FIG. 3 shows an embodiment of the enlarged display processing of the present invention, which will be described based on the flowchart. In the enlarged display processing of the present invention, the user can perform the conventional enlarged display processing.
The enlargement command input 16 and the enlargement area designation 17 of FIG. 2 which have been performed by the above are not required, and the enlargement display processing by the system is performed only by the edit target selection 29 and the edit command input 30. In the enlarged display processing by the system, first, it is determined 31 whether or not the edit target 39 is enlarged and displayed. This is because if the edit target is enlarged, the user may have properly enlarged it. Considering this, processing to prevent further enlargement is performed. Is. When the enlarged display has already been made, the edit command 40 is executed as it is. Edited command 40 input if not enlarged
Is determined to determine whether the command is an expansion target command. This is a process that does not require the enlarged display depending on the type of the edit command, so that the enlarged display process is not performed for these commands. If the command does not require enlarged display, the edit command 40 is executed as it is. If the command is an enlarged display target command, then the size acquisition 33 of the edit target 39 is performed, and based on this, the display magnification calculation 34 is performed so that the edit target is displayed on the entire screen. The display magnification is calculated according to the state of each element, and the corrections shown in FIGS. 4 to 9 described below are added. The display magnification is calculated and corrected, and the enlarged display processing 35 for performing the enlarged display 41 is performed based on this.

Here, a display screen example of enlarged display correction and correction of display magnification calculation of FIG. 3 are divided into three elements of a figure, a character, and a table (processes 33 and 34 surrounded by a bold dashed line).
The detailed processing flow of 35) will be described. First, FIG. 4 shows a display screen example of enlarged display correction of a graphic element. (A) shows an original figure and (b) shows an enlarged correction figure. For graphic elements,
A display area 43 at the time of enlarged display on the editing screen 42 is assumed. On the system side, the display magnification is calculated so that the edit target graphic 44 covers the entire display area 43. The upper display screen is an example in which the display magnification is appropriate. However, when the display area 43 is displayed at a magnification that is the entire surface, the edit target graphic 45 may not be displayed as shown in the middle display screen (indicated by the one-dot chain line).
The display magnification is corrected 46 in the direction of reduction so as to fit inside. When the edit command for the edit target graphic 44 is a command that may be larger than the original graphic such as enlargement / expansion, the edit target graphic is displayed 47, which is slightly smaller than the display area 43, as in the lower display screen. Correct the magnification so that Subsequently, FIG. 5 shows a detailed processing flow relating to enlarged display correction of graphic elements. The left side is the processing flow of FIG. 3, and the right side is the detailed processing flow corresponding thereto. In order to understand this detailed processing flow, (a)
Shows the original figure, and (b) shows the enlarged correction figure. Step (1): To calculate the enlargement ratio, obtain the width of the target graphic to be enlarged and displayed. Step (2): To calculate the enlargement ratio, obtain the height of the target graphic to be enlarged and displayed. Step (3): Obtain the width of the display area for calculating the enlargement ratio. Step (4): Obtain the height of the display area for calculating the enlargement ratio. Step (5): Obtain the maximum magnification in each of the width and height directions. Of these, the enlargement ratio is set in accordance with the one with the smaller magnification so as not to overflow the display area. Steps (6) and (7): When there is a possibility that the size will be larger than the original figure by the command operation, the magnification is reduced by N% to leave the editing area. N is a reduction ratio arbitrarily set by the system. Step (8): The coordinates of each vertex of the corresponding figure are vertically calculated, and the coordinates A, B, and C after enlargement are multiplied by V in the horizontal direction. Steps (9) and (10): When the coordinates calculated in step (8) extend beyond the display area, the enlargement magnification V is reduced by S% so as not to extend and the coordinates are calculated again. S is a correction reduction ratio arbitrarily set by the system side. Step (11): Based on the coordinates calculated in step (8), the corresponding figure is enlarged and displayed in the center of the display area.

Next, FIG. 6 shows an example of a display screen for correction of enlarged display of character elements. (A) shows an original figure and (b) shows an enlarged correction figure. In the case of a character element, the character display area 48 in the edit screen 42 is assumed. On the system side, when a command is input, the line position where a rectangle called a cursor 49 indicating the character position to be edited exists and the length of the character display area 48 in the line direction are obtained. Based on these, the display magnification is calculated such that half the length in the row direction is displayed on the entire surface of the character display area 48 with the row position where the cursor 49 is present as the center. An example of this display screen is shown in the upper part. However, if the line position 50 where the character to be edited exists is the end of the character display area 48 and the display is performed centering on that position, if there is a space in the character display area 48, the center line position is corrected. However, the character display area 48 is prevented from becoming empty. An example of this display screen is shown in the lower part. Next, FIG. 7 shows a detailed processing flow relating to enlarged display correction of character elements. The left side is the processing flow of FIG. 3, and the right side is the corresponding detailed processing flow. In order to understand this detailed processing flow, (a) shows an original figure and (b) shows an enlarged correction figure. Step (1): Obtain the width of the character display area for calculating the enlargement ratio. Step (2): Obtain the height of the character display area for calculating the enlargement ratio. Step (3): 1 / in the row / column direction, which is the enlarged display range
Calculate the size of 2. Step (4): The diagonal point coordinates of the area to be enlarged are calculated with the enlarged display target character as the center. Steps (5) and (6): When the right edge () after the enlarged display is larger than the right edge () of the actual display area, the display is shifted to the left and the right edge is aligned with the actual display area.

[0010]

[Table 1]

Steps (7), (8) and (9): When either the upper end or the lower end after the enlarged display becomes larger than the upper end or the lower end of the actual display area, the display is shifted up or down to the upper end or Align the bottom edge with the actual display area.

[0012]

[Table 2]

Step (10): Step (4)-
The display is enlarged in the display area of the diagonal coordinates calculated in (9).

Next, FIG. 8 shows an example of a display screen for enlarged display correction of table elements. (A) shows an original figure and (b) shows an enlarged correction figure. In the case of a table element, it is assumed that the display area 51 at the time of enlarged display in the editing screen 42. On the system side, the display magnification is calculated such that the entire table is displayed on the entire display area 51, centering on the frame 52 in the table that is to be edited when the command is input. An example of this display screen is shown in the upper part.
However, when the edit target table 53 is large and the display magnification does not reach a certain magnification when enlarged, a few surrounding frames are displayed in the display area 51 centering on the frame to be edited. Correct the magnification so that An example of this display screen is shown in the lower part. Next, FIG. 9 shows a detailed processing flow relating to the enlarged display correction of the table element. The left side is the processing flow of FIG.
The right side is the detailed processing flow corresponding to this.
Further, in order to understand the detailed processing flow, (a) shows an original figure and (b) shows an enlarged correction figure. Step (1): To calculate the enlargement ratio, obtain the width of the target table to be enlarged and displayed. Step (2): To calculate the enlargement ratio, obtain the height of the target table to be enlarged and displayed. Step (3): To calculate the enlargement ratio, obtain the width of the display area to be enlarged. Step (4): To calculate the enlargement ratio, obtain the height of the display area to be enlarged. Step (5): Obtain the maximum magnification in each of the width and height directions. Of these, the enlargement ratio is set in accordance with the one with the smaller magnification so as not to overflow the display area. Steps (6) and (7): When the enlargement magnification is smaller than the minimum magnification arbitrarily set by the system, the enlargement display area centering on the relevant frame is calculated. The size of the area to be calculated is half the width and height of the original table.

[0015]

[Table 3]

Step (8): If the enlargement magnification is equal to or larger than the minimum magnification, the coordinates of the four corners of the table are multiplied by V in the vertical and horizontal directions to calculate the enlarged coordinates. Step (9): Based on the coordinates calculated in step (7) or (8), the table is enlarged and displayed in the center of the display area. After the enlarged display as described above, the user starts the editing 36 in FIG. When the display is returned to the original state after the editing is completed, the reduction display processing 38 on the system side by the reduction command input 37 by the user is performed as in the case of FIG.

In addition to the basic operation described above, the enlarged display state setting as one function of this method will be described with reference to FIG.
Enlarged display may not be necessary when editing such as aligning the entire document. In this situation,
Enable / disable setting of enlarged display to prevent enlarged display. As shown in FIG. 10, this is a common command on the document editing screen 9 that is a tool 54.
This is done by selecting the enlarged display 55 command in the menu displayed by command designation. When the enlarged display 55 command is selected, a window called an enlarged display state setting sheet 56 is displayed. From this sheet 56, the user sets, for each of the graphic type, character type, and table type data, whether or not enlarged display is performed by the system. As for what is not done in this sheet 56,
The system does not enlarge the display. As a result, when the enlarged display is not necessary, the user can arbitrarily prevent the enlarged display, so that efficient editing can be performed. As described above, the enlarged display of the present invention is larger than the conventional enlarged display processing method in the enlargement command input 16 of FIG.
Since the two procedures of the enlargement area designation 17 can be omitted, it is useful for improving the operability of the document editing operation for frequently performing the enlargement display. Further, the conventional enlargement 24 command can be used as it is, and the enlargement display of the area designation by the user can be performed, so that the operability can be further improved.

In the above description, the method of performing all the enlarged display on the system side has been described, but hereinafter, a method of implementation other than this will be described. FIG. 11 shows another embodiment of the present invention, which is a flow chart showing a processing procedure of a method in which a user sets a magnification at the time of enlarged display, and an edit target is enlarged and displayed according to a designated magnification when an edit command is inputted. -Indicates a chart. Figure 1
Reference numeral 2 denotes an "enlarged display magnification setting sheet" which is a window displayed when the user sets the magnification. In this method, the user first sets the magnification 61 by the magnification setting command 60. The setting is the common command, Tool 5
Menu displayed by specifying 4 commands
This is done by selecting the middle magnification setting 70 command. When the magnification setting 70 command is selected, the enlargement display magnification setting
A window called a window 74 is displayed. With this sheet, the magnification is set for each of the graphic type 71, the character type 72, and the table type 73 data. The default value of the magnification is 1, and in the case of 1, it has the same meaning as not performing enlarged display.
If the magnification is set once, the value of the magnification set immediately before is held unless changed. After the magnification is set, the user performs the edit target selection 62 and the edit command input 63, so that the system displays the edit target in an enlarged scale.
In the enlarged display by the system of this method, first, a determination 64 is made as to whether or not the edit target is enlarged and displayed. This is because if the edit target is enlarged, the user may have properly enlarged it. Considering this, processing to prevent further enlargement is performed. Is. If the enlarged display has already been made,
The edit command 63 is executed as it is. If it is not enlarged and displayed, it is determined whether or not the input edit command 63 is a command to be enlarged 65. this is,
Depending on the type of the edit command, there is a case where the enlarged display is not necessary, and in consideration of this, the process is such that the enlarged display process is not performed for these commands. If the command does not require enlarged display, the edit command 63 is executed as it is. If the command is an enlarged display target command, then the edit target is enlarged displayed 66 on the screen at the magnification set by the user. After the enlarged display, the user starts editing 67. When the display is returned to the original state after the editing, the reduction display processing 69 on the system side is performed by the user's reduction command input 68, as in FIG. In this method, the procedure of setting the magnification is increased, but the user can set an arbitrary magnification for each data type, which has an advantage that finer enlargement display control can be performed.

Next, embodiments other than the above two embodiments will be described based on the flowchart of FIG.
FIG. 13 shows another embodiment of the present invention, in which the enlargement display processing is performed on the system side, but the timing for performing the enlargement display is a method designated by the user by providing a command "automatic enlargement". is there. In this method, first, the edit target designation 7 is performed for the edit target 84 to be enlarged and displayed.
5 and then by the command of automatic enlargement 85,
The automatic enlargement command designation 76 is performed. At this point, the enlarged display processing by the system side is executed. In the enlarged display process, first, the size acquisition 77 of the edit target 84 is performed. A display magnification calculation 78 is performed based on the size of the edit target 84 so that the edit target 84 is displayed on the entire screen. The correction in calculating the display magnification at this time is similar to the correction for each element described with reference to FIGS. After the display magnification is calculated, the enlarged display processing 79 for the enlarged display 41 is performed based on the calculated display magnification. After the enlarged display, the user inputs 80 the editing command 86 and starts editing 81. When the display is returned to the original state after the editing is completed, the reduction display processing 83 on the system side by the reduction command input 82 by the user is performed as in the case of FIG.
In this method, the procedure of "automatic enlargement" command input is increased, but there is an advantage that the enlargement display function by the system can be used only when the user needs the enlargement display. In the above description, the present invention has been described by taking the document editing apparatus as an example, but the present invention can be applied to other systems. For example, it can be applied to an enlarged display method of partial enlargement when editing a drawing of a CAD system.

[0020]

According to the present invention, since the enlarged display of the object to be edited is performed only by inputting the edit command, the editing operation of the technical document having many figures and tables requiring the enlarged display at the time of editing. Can be reduced and simplified. Further, since the time and effort of the editing operation by the user can be saved, the editing can be speeded up.
