Description

[0001]
[Industrial application fields]
The present invention relates to a document creation apparatus such as a Japanese desktop publishing system or a word processor.
[0002]
[Prior art]
When creating a matrix in a document containing mathematical expressions, a reader for omitting elements in the matrix may be attached. The leader is usually arranged with the points horizontally, vertically or diagonally. In the conventional document creation apparatus, a special function for attaching a reader is not provided, and when the user attaches the reader, the font of the three or two readers is added to the element to which the reader is attached by manual operation. It was created by typing. Also, when the reader is drawn at the diagonal of the matrix, the setting is made by rotating the font of the input reader one by one.
[0003]
[Problems to be solved by the invention]
However, in such a manual setting procedure by the user, when the reader wants to draw across a plurality of elements, the distance between the points varies unless the distance between the elements and the distance between the points in the font of the reader are the same. In addition, when the reader is pulled diagonally, there are problems that the angles are scattered and difficult to arrange in a straight line, the workmanship tends to be poor, and the work efficiency is low. .
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a document creation apparatus that can easily set readers in a matrix and draw linear readers at equal intervals.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides reader information setting means for setting information for drawing a reader from one element in a matrix to another element, and reader information by means of reader information acquired by the reader information setting means. And a reader drawing means for drawing the reader in the matrix.
[0006]
[Action]
With the above configuration, the position, length, and the like of the reader are obtained by calculation and drawn.
[0007]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0008]
FIG. 1 is an explanatory diagram of reader usage within a matrix in one embodiment of the present invention. As shown in the drawing, leaders are drawn from element a ₁₁ to element a _mn , from element a ₁₁ to element a _m1,. At this time, it means that the element at the position to which the reader is attached is omitted.
[0009]
FIG. 2 is a circuit block diagram of the document creation apparatus in one embodiment of the present invention. The document creation apparatus of this embodiment includes a keyboard device 1 and a CRT display device 5 in appearance. The keyboard device 1 includes, for example, a character input key and an edit control key, and operates the character input key. Thus, the character code corresponding to the operated key and the control code are given to the CPU 2 by operating the editing control key. The control code here includes leader information, and the leader information includes the leader line type (whether to create a leader by dots or to have a ruled line attribute). Note that the coordinates of the start point and end point of the reader are determined from the position of the caret to which this control code is attached, and the length and angle of the reader are calculated from these coordinates. The CPU 2 sets the start / end positions of the in-matrix reader based on the above-described control code according to the editing program recorded in advance in the ROM 3, and calculates and sets the start / end points / distance / angle of the reader. Perform the action. Reference numeral 4 denotes a RAM, which is input by at least the editing control key of the keyboard device 1 and stores the in-matrix reader information edited by the CPU 2, and is input by at least the editing control key of the keyboard device 1 and edited by the CPU 2. A data area 42 for storing matrix information, and a sentence buffer 43 for storing sentence data input by at least a character input key of the keyboard device 1 and edited by the CPU 2. The text data is edited into a predetermined text format together with the sequence information data, the reader information data in the sequence, etc., and displayed on the CRT display device 5.
[0010]
Next, the operation of the document creation apparatus of this embodiment will be described with reference to the flowchart of FIG.
[0011]
First, the caret is moved to the matrix element to be set by the matrix reader (S1). Next, with the matrix element at the current caret position as the starting point, the end element, line type, and position within the element (including or not including the specified element) are set (S2). The set information is stored in the document data of the document buffer 43 as a control code (FIG. 3A).
[0012]
When actually formatting, it is determined whether the in-array leader is currently set (S4). If it is set, the start / end element, line type, and position within the element are obtained from the in-array leader data. Then, the sequence information data is acquired (S6). Further, the coordinates of the start / end points of the leader of the start / end elements are calculated from the start / end elements and the in-element position / array information data acquired in (S4) and (S5) (S7). Thereafter, the length and angle of the reader are calculated from the coordinates of the start / end points (S8). Drawing is performed based on the calculated coordinates, length, and angle (S9) (FIG. 3B).
[0013]
【The invention's effect】
In the present invention, the reader data representing the omission of the matrix is set to the caret position from the keyboard while editing the text, so that the desired matrix element position can be set accurately and neatly. You can create sentences.
