Abstract

PURPOSE:To facilitate character justification by adjusting the arrangement of the valid characters of each line in a designated area according to the kind of the designated character justification in the designated area. CONSTITUTION:An editing menu is displayed by operating a pointing device 9 (or keyboard 7), and the 'right justification' of a character justification item is selected. Then, a cursor being interlocked with the pointing device 9 is moved to a left-and-up corner position, a button provided in the device is pressed, the cursor is moved to a right-and-down corner position, the button of the pointing device 9 is pressed, and the right-and-down position of the block is decided. Thus, the characters at the tail end of each character string on the screen during editing can be justified. And also, a position change is operated by inserting spaces in a number calculated according to a designated block width, the length of the character string to be processed for the character justification, and the kind of the character justification into the head position of the character string under consideration.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a document processing method and apparatus,
More particularly, it relates to a document processing method and apparatus for creating and editing a document.

[0002]

2. Description of the Related Art Generally, an apparatus of this type edits a document by aligning a character string to the right with respect to a certain line or centering (hereinafter collectively referred to as character aligning) a document format. It has a function.

Character alignment is performed by designating a target line (or character string) and then giving a character alignment instruction such as right alignment to the character string in the selected line. On the contrary, first specify the type of character alignment,
Some then specify the lines of interest.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[Description of Apparatus Configuration] FIG. 1 shows the configuration of a document processing apparatus according to an embodiment. In the figure, 1 is a CPU that controls the entire apparatus, and 2 is a ROM that stores a boot program, character fonts, and the like. A RAM 3 is used as a work area for the CPU 1 and stores a document being edited. Reference numeral 4 is a VRAM that expands information to be displayed on the display screen 102, 5 is a display control unit that controls the display, and 6 is a display unit (CRT) that displays the contents of the VRAM 3 under the control of the display control unit 5. is there. Reference numeral 7 is a keyboard for giving characters and various instructions. Reference numeral 8 denotes an external storage device that stores an OS and a program related to document processing (including the program of the flowchart of FIG. 4 which is dictated). Reference numeral 9 denotes a pointing device (mouse) for designating an arbitrary position on the display unit 6.

[Description of Processing Outline] An outline of processing in the apparatus of the embodiment having the above configuration will be described below.

FIG. 2 shows an example of a document being edited, and the character strings "100 yen", "200 yen", "300 yen".
Shows the state where the right ends of are not aligned. In a document in such a state, the following operations are performed to align the right ends of the above character strings.

First, the pointing device 9 (or the keyboard 7) is operated to display an edit menu (not shown), and "right alignment" (not shown) in the character alignment item is selected. Other types of character alignment include “left alignment” and “center alignment”.

After that, a block (rectangular area) enclosing only the character string to be aligned is specified. Blocks can be designated by both the cursor movement keys provided on the keyboard 7 or the pointing device 9, but an example of using the latter pointing device 9 will be described here. Since the block can be specified by the upper left corner position and the lower right corner position, first, the cursor interlocking with the pointing device 9 is moved to the upper left corner position, and the button provided on the device is pressed. Then, the cursor 202 is moved to specify the lower right corner position. At this time, in order to allow the operator to intuitively understand what block is being specified, the rectangle specified by the specified start point (upper left corner position) and the moving end point is real-time. Update the display. The broken line in the figure indicates the rectangle, and 202 indicates the cursor.

Thus, when it is confirmed that the right side of the quadrangle is displayed at the position to be right-justified including the character string to be right-justified (here, right-justified), the button of the pointing device 9 is pressed, Determine the lower right corner position of the block.

As a result, the screen being edited is updated as shown in FIG. 3, and the character string "100" is returned as intended.
It is possible to align the last character "yen" of each of "yen", "200 yen", and "300 yen." The principle for changing the position of the character string is At the beginning of the string, insert a space of the specified block width, the length of the string of interest, and the number of spaces calculated according to the type of character alignment to the beginning of the string of interest. ..

When a block is designated by the keyboard 7, the same operation may be performed. Specifically, the cursor movement key is operated to move the cursor to the upper right corner position of the block, and, for example, the return key is pressed. Then, the cursor movement key is operated again to move the cursor to the lower right corner this time, and the return key is pressed. During this period, the operator is allowed to display the quadrangle indicating what area is being specified, as described above.

As described above, the character string to be aligned can be specified and the area to be aligned can be specified in a single operation, and the position of the aligned characters is substantially the operator's preference. You can set it freely with.

[Explanation of Processing Contents] In order to realize the above processing, the CPU 1 of the embodiment executes the processing according to the flow chart shown in FIG. It should be noted that the flowchart is a process after designation of a character alignment item on a menu screen (not shown).

First, in step S1, the type of character alignment is selected. As described above, there are three types of character justification: left justification, center justification, and right justification.

Next, in step S2, the block to which the characters are to be aligned is designated. Based on the block specified in step S3, the width W and the number of rows H of the block
Calculate (height). The block width W is calculated for how many half-width characters.

The process proceeds to step S4 and RAM
The initial value "1" is set to the variable i provided at the predetermined address in 3
Is substituted. This variable i represents the number of rows to be processed. Next, the process proceeds to step S5, and the variable i is compared with the row number H of the designated block. In this comparison,
While it is determined that i ≦ H, the processes in and after the next step S6 are repeated, and when it is determined that i> H, this process ends.

Now, in step S6, a valid character string in the i-th row in the designated block is detected, and the length L of the valid character string (= numerical value indicating a half-width character) To get The meaning of the valid character string here is a character string excluding the space code and tab code,
Refers to the character strings that make up the "sentence" itself. However, when multiple valid character strings are separated by spaces etc.,
Since it can be judged that the space or the like that functions as the delimiter is used to intentionally separate the character strings before and after the space, the space is also processed as a valid character.
If there is a line feed code immediately after the valid character string,
The line feed code is not counted in the length of the effective character string described later, but is added after the last character of the effective character string when rearranging.

In short, a valid character string is defined as a character string that is sandwiched between the first valid character that is traced from the beginning of a line and the first valid character that is traced from the end of a line.

When the effective character string in the line indicated by the variable i and its length L are thus determined, the process proceeds to step S7, and the specified type of character alignment is discriminated, whereby step S8 is performed. ~ Branch to S9.

When it is determined that the type of character justification is "left justification", the process proceeds to step S8. Since "left justification" is to align the first character of the effective character string with the left side of the specified block, there is no space to insert in this case (S = 0).

In the case of "centering" (step S9), the process proceeds to step S9, and the number S of insertion spaces is calculated by the following equation.

S = (W−L) / 2 Needless to say, the meaning of this expression is simple, but in brief, subtracting the effective character string length from the specified block width means that block. This means that the total number of blanks in is calculated. Then, half the total number of blank spaces is to be inserted at the beginning position of the effective character string. However,
It is possible that S may not be an integer in some cases. In this case, the fractional part is rounded down, but of course, it may be rounded up.

The number of insertion spaces S in the case of "right justification" (step S10) is as follows. The meaning is clear from the above description and will not be described.

S = W-L Now, when the number S of insertion spaces for the line of interest (line in the block indicated by the variable i) for each character alignment is determined in this way, the process proceeds to step S11. Here, a process of inserting S spaces at the beginning position of the effective character string of interest is performed. In the next step S12, a character string composed of S spaces and subsequent effective character strings of length L is arranged in the i-th row in the designated block.

After that, in order to process the next line,
The variable i is incremented by 1, and the process returns to step S5.

The above processing is performed in step S5 by "i>H".
It will be repeated until it is judged.

As described above, according to this embodiment, the character string to be character aligned and the character alignment range can be specified by a single operation, and the position of character alignment is virtually unlimited and free. It will be possible to do it in any position.

In the above-described embodiment, the type of character justification is specified first, and then the block is specified.
This order may be reversed. That is, step S1
The order of step S2 and step S2 may be interchanged.

In the embodiment, the case where the document on the display screen is written horizontally is described, but it may be written vertically. In this case, it goes without saying that the width of the block indicates the length of the block in the vertical direction.

Further, in the embodiment, it is assumed that a line feed code exists immediately after the effective character string when performing each character alignment process, but a space is filled in the entire line immediately after the effective character string. In this case, a space that is overwritten (deleted) at the movement destination of the valid character string may be inserted after the valid character string to eliminate the shift over a plurality of lines.

As described above, according to the present invention, it is possible to perform character alignment to a desired position with a simple operation.
