BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus, and more particularly to a method for rearranging a character string when the area frame in which the character string is displayed is enlarged or reduced.

[0002]

2. Description of the Related Art Conventionally, in this type of document creating apparatus, a character string such as ABCD ... Is displayed in an area frame (hereinafter also simply referred to as an area) as shown in FIG. 7 is displayed, and when the point shown in B of FIG. 7 is specified and the enlargement instruction of the area A is given to the apparatus, the area A can be enlarged and displayed as shown in FIG. 7B. it can. However, in the case of enlarging the area b in this way, if the size, character pitch, line pitch, etc. of the character are left unchanged, the number of characters in one line and the number of lines increase by the amount of the increased area. The columns are displayed as shown in FIG. 7B, and the arrangement becomes different from the arrangement before enlargement in FIG. 7A. That is, when the area B is enlarged or reduced in the document creating apparatus of this type in the related art, the number of characters per line or the number of lines of the character string displayed in the area is changed,
There is a drawback that the area cannot be expanded or reduced without changing the number of characters or the number of lines in one line of the internal character string. Therefore, in order to correct this, the operator operates the keyboard after changing the size of the area and changes the format of the internal characters and re-enters the text to display the character string displayed in the area before the change. The number of characters per line and the number of lines must be adjusted, which is disadvantageous in that it takes time and labor.

[0003]

As described above, in the conventional document creating apparatus, when the area in which the character string is displayed is enlarged or reduced, the displayed characters are increased or decreased as the area increases or decreases. Since the number of characters per line or the number of lines is changed, there is a drawback in that the character string cannot be enlarged or reduced without changing the arrangement of the character string before the enlargement or reduction.

Therefore, the present invention eliminates the above-mentioned drawbacks and creates a document in which an area including a character string can be enlarged or reduced without changing the number of characters and the number of lines in the character string. The purpose is to provide a device.

[0005]

According to the first aspect of the present invention, there is provided a document creating apparatus having a function of enlarging or reducing an area frame in which a character string is arranged, in which the enlargement or reduction ratio of the area frame is calculated. The number of characters and the number of lines of the character string before the enlargement or reduction of the area frame are the same after the enlargement or reduction of the area frame based on the calculation means and the enlargement or reduction ratio calculated by the first calculation means. The second calculation means for calculating the parameters for determining the character size, the character-to-character spacing, etc., and the character size and the character-to-character spacing determined by the parameters calculated by the second calculation means. And a control means for arranging the character string in the enlarged or reduced area frame.

[0006]

In the document creating apparatus of the present invention, the first calculating means calculates the enlargement or reduction ratio of the area frame. The second calculating means calculates the first calculating means, and based on the enlargement or reduction ratio, the number of characters per line and the number of lines of the character string before the enlargement or reduction of the area frame are after the enlargement or reduction of the area frame. The parameters for determining the character size and the character-to-character spacing, etc. are calculated so that they are the same. The control means arranges the character strings in the enlarged or reduced area frame at the character size and the character-to-character spacing determined by the parameter calculated by the second calculating means.

Next, the operation of this embodiment will be described. When the operator inputs the reading of the document from the keyboard 4, the CPU 1 receives the reading information via the keyboard interface 5, and uses the kana-kanji conversion program 211 in the ROM 2 or the dictionary data in the dictionary area 22 to convert the kana-kanji. And create a document. The document thus created is written in the document buffer 31 in the RAM 3 and is displayed on the screen of the display device 6 by the display controller 7. At this time, the display control unit 7 performs control to expand the character data in the display RAM 8 and display it on the display device 6. At this point, the operator can operate the keyboard 4 to display a region a as shown in FIG. 2 on the screen of the display device 6 and display alphabetic characters such as ABCD ... The CPU 1 writes the area A displayed on the display device 6 and the letters displayed inside the area B into the document buffer 31 by the CPU 1.

As shown in FIG. 2, the operator displays the area a on the screen of the display device 6 and the character string in the area a, and
When the area correction key of the keyboard 4 is pressed, the CPU 1 receives this and executes the document editing program 212 in the ROM 2 to display a square mark on the four corners of the area A on the screen of the display device 6 as shown in FIG. indicate. The operator who sees this operates the keyboard 4 to specify one of the marks (1), and a ↓ mark is displayed near the specified mark (1). By pressing the next candidate key on the keyboard 4, this ↓ mark is displayed by changing the pointed position from point a → point b → point c → point d → point a. here,
By placing ↓ at the point c and operating the move key of the keyboard 4, the operator moves the point c to the outside of the frame of the first area B as shown in FIG. The control on the screen of the display device 6 as described above is sequentially performed by the CPU 1 according to a command input from the keyboard 4.

When the operator presses the selection execution key of the keyboard 4 in the state shown in FIG. 4, the CPU 1 newly moves and determines the size of the area a to be newly enlarged from the position of the point c decided. Then, the display controller 7 displays the enlarged new area B on the display device 6 based on the calculated height. Next, the CPU 1 determines the size, character pitch, line pitch, etc. of this character string so as not to change the number of characters per line or the number of lines of the character string displayed inside the area B shown in FIG. 2 before enlargement. The calculation for changing the parameter is performed using the calculation buffer 32 provided in the RAM 3.

FIG. 6 is a diagram showing the size of the area B before enlargement shown in FIG. 2 and the parameters defining the internal character string. In this figure, Lx is the length of the original region in the x direction, Ly is the length of the original region in the y direction, mp is the character pitch in the original region, and lp is the line in the original region. Pitch, s
x is the character size in the original area (x direction), sy is the character size in the original area (y direction), wx is the margin between the character string in the original area and the area frame (x direction) , Wy is the margin between the character string in the original area and the area frame (in the y direction), m is the number of characters per line in the original area, and l is the number of lines in the original area. Here, as shown in FIG. 5, parameters that define the size of the changed area B and the internal character string are defined as follows.
That is, Lx ′ is the length in the x direction after changing the region frame, Ly ′ is the length in the y direction after changing the region frame, mp ′ is the character pitch after changing the region frame, and lp ′ is the line after changing the region frame. Pitch, sx '
Is the character size after changing the area frame (x direction), sy ′ is the character size after changing the area frame (y direction), wx ′ is the margin between the character string after changing the area frame and the area frame (x direction), wy Let 'be the margin (y direction) between the character string and the area frame after the area frame is changed.

First, the CPU 1 calculates the enlargement ratio ax in the x direction and the enlargement ratio ay in the y direction from the size of the area a before the enlargement and the size of the area a after the enlargement by using the following equation (1). To do. ax = Lx '/ Lx ay = Ly' / Ly (1) The character pitch and the line pitch of the characters displayed in the enlarged area A are shown below using the enlargement ratios in the x and y directions ( 2) Calculate with the formula. mp ′ = ax × mp lp ′ = ay × lp (2) Further, the character size after the area expansion is calculated by the expression (3) using the expansion ratio. sx ′ = ax × sx sy ′ = ay × sy (3) After that, the region is expanded by the formula (4) using the length of the region after the region expansion, the character pitch, and the number of one-line characters and the number of lines in the original region. The margin between the enlarged character string and the area frame is calculated. wx ′ = (Lx ′ − (mp ′ × m)) / 2 wy ′ = (Ly ′ − (lp ′ × l)) / 2 (4)

The CPU 1 uses the formulas (1) to (4) described above so that the number of characters m per line and the number l of one line of the character string displayed in the region after enlargement are the same as before enlargement. When the character pitch, the line pitch, the character size, the area frame, and the margin of the characters displayed in the area of are calculated using the calculation buffer 32,
After changing the document format of the character string displayed on the display device 6 so as to match these parameters, the character string is displayed in the area on the screen of the display device 6 as shown in FIG. At this time, the CPU 1 changes the document header data in the document buffer 31 so as to match the changed format. The example of calculating the parameters of the CPU 1 has been described with respect to the case of enlarging the area, but when the area is reduced, the number of characters and the number of lines of the character string in the area before the reduction are displayed so as not to be changed. An operation of calculating a character parameter and displaying the character string in the reduced area in a format corresponding to the parameter is performed.

According to the present embodiment, when enlarging or reducing the area containing the character string, the number of characters per line of the character string displayed in the area before the change is the same as the number of characters per line. And in order to display the character string in the area after the change with the number of lines, the parameter of the character to be displayed in the area after the change is calculated by using the enlargement or reduction ratio of the area so as to meet the above condition. Since the character string is displayed in the changed area in the format corresponding to the parameter, when the area is enlarged or reduced, the number of characters per line and the number of lines in the internal character string are not changed, The character string can be displayed in the area after reduction, and the operability of the device can be improved.

[0015]

As described above, according to the document creating apparatus of the present invention, the area containing the character string is enlarged or reduced without changing the number of characters and the number of lines in one line of the character string. be able to.
