Abstract

PURPOSE:To freely set an arrow mark pattern by a worker by displaying an arrow mark based on the data such as an angle and a size to decide the shape of the arrow mark. CONSTITUTION:A scroll bar is constituted of the arrow in two directions, a stripe part (valuator), and the void part (slider) to move in the valuator, and by the position in the valuator, the rate to the maximum value to which an angle and a size can be set is shown. From an input means 4, the instruction of the angle designation is performed, and when it is the instruction of the arrow mark in the large direction, a CPU 1 makes an arrow mark angle in an arrow mark attribute storing area 3-1 into +1 deg., moves the slider in the large direction, and at the time of the instruction in the small direction, makes it into the inverse of -1 deg. and moves it in the small direction. At the time of the instruction of the position in the valuator, the rate obtained at the instructing position is multiplied to the maximum value of the angle, the arrow mark angle is counted, and the arrow mark angle stored in the storing area 3-1 is changed. After the arrow mark attribute is changed, the CPU 1 instructs to an image controller 6, and at the central part of the set screen, the arrow mark is drawn.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device such as desktop publishing (hereinafter referred to as DTP) capable of performing various document edits such as drawing a line at a desired position in a document. is there.

[0002]

2. Description of the Related Art A conventional data processing apparatus has a function of outputting a ruled line with an arrow. In this case, a plurality of arrow patterns can be stored in advance and displayed on a selection screen as shown in FIG. 11, and corresponding ruled lines with arrows can be output according to the instruction selection by the operator.

[0003]

However, the conventional data processing device has a problem in that the arrow pattern can be set only by selecting an existing pattern, and the degree of freedom in setting the arrow pattern is low. Was there.

[0004]

In order to solve the above-mentioned problems, the present invention provides a display means for visually displaying a graphic,
An input unit for inputting data such as an angle and a size for determining the shape of the arrow, and a unit for outputting the arrow to the display unit based on the data input from the input unit.

[0005]

According to the present invention, the above-described means can specify the parameter for determining the shape of the arrow to form the arrow having a desired shape.

[0006]

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

FIG. 1 is a block diagram of a data processing device according to an embodiment of the present invention, in which 1 is a central processing unit (hereinafter referred to as CPU) which controls the device and processes data, and 2 is a program instruction. Read-only memory (hereinafter referred to as ROM) for storing data such as 3) random access memory (hereinafter referred to as RAM) for storing data, 4 input means such as keyboard and mouse, 5 image memory, 6 image An image controller for drawing characters and figures in the memory 5, and a cathode ray tube display (hereinafter CR)
Reference numeral 8 denotes a printer.

As shown in FIG. 2, the pattern of the arrow is managed by the line width of the line to which the arrow is attached, the size of the arrow, and the angle.

An arrow attribute storage area 3-1 stores the size and angle of the set arrow as shown in FIG. Three
A line width storage area -2 stores the set line width as shown in FIG. The image controller 6 draws an arrow and a line based on the arrow attribute and the line width.

The operation of the data processing apparatus of this embodiment having the above configuration will be described below with reference to the flow charts of FIGS.

(1) Setting of line width and arrow pattern

First, the CPU 1 initializes the size, angle and line width of the arrow in the arrow attribute storage area 3-1 and the line width storage area 3-2 (S50). Here, when the line width is set from the input means 4, the CPU 1 updates the line width in the line width storage area 3-2 based on the set value (S52, S53). When an arrow setting instruction is issued from the input means 4, the CPU 1 performs arrow setting processing (S5).
4, S55). When the confirmation instruction is issued, this process ends (S56).

The arrow setting process will be described below with reference to the flow charts of FIGS.

First, the CPU 1 causes the CRT 7 to display an arrow setting screen as shown in FIG. 10 (S60). On this setting screen, an arrow pattern based on the current set value is displayed in the center. The left side of the arrow display portion is a scroll bar for setting an angle, and the lower side is a scroll bar for setting a size. The scroll bar is composed of a two-way arrow, a striped portion (hereinafter referred to as valuator) and a white portion (hereinafter referred to as slider) that moves within the valuator, and the angle and size can be set depending on the position inside the valuator. Ratio to maximum value (0% to 1
00%). In this case, the maximum angle value is 40 ° and the maximum size value is 30 dots. Here, the angle setting (S62), the size setting (S63) from the input means 4,
Confirmation (S64), processing is performed according to either instruction.

If there is an angle setting instruction from the input means 4 (S62), and if the instruction is a large arrow instruction (S70), the CPU 1 increments the arrow angle in the arrow attribute storage area 3-1 by +1. To move the slider in the large direction (S7
1) If the instruction is a small arrow (S72), the arrow angle is set to -1 ° and the slider is moved in the small direction (S7).
3). If it is a position indication in the valuator (S7
4) The angle of the arrow is calculated by multiplying the maximum value of the angle by the ratio obtained by the designated position (S75), and the arrow angle stored in the arrow attribute storage area 3-1 is changed (S76). After changing the arrow attribute, the CPU
1 instructs the image controller 6 to draw an arrow in the center of the setting screen. (S77).

When there is a size setting instruction from the input means 4 (S63), the process according to the flow chart of FIG. 8 is performed, but since this is the same as the case of the angle setting, the description thereof will be omitted. ..

(2) Line drawing

The CPU 1 acquires the start point and end point coordinates designated by the input means 4 (S90), reads the set line width from the line width storage area 3-2 (S91),
Based on the start point coordinates, the end point coordinates, and the line width, the image controller 6 is caused to draw a line on the image memory (S92). After drawing the line, the CPU 1 reads the arrow attribute from the arrow attribute storage area 3-1 (S93), and draws the arrow based on the arrow attribute in the same manner as the line, with the start point or the end point of the drawn line as a reference. (S94).

As described above, in this embodiment, the angle and size for determining the shape of the arrow can be set to desired values through the scroll bar, so that the operator can freely set the arrow pattern. can do.

Further, since the scroll bar is used for inputting the angle, size and the like, and the display of the arrow pattern is switched according to the instruction of the scroll bar, the operability is improved.

It is obvious that the former effect can be obtained by directly inputting values such as angles and sizes without using the scroll bar.

[0022]

According to the present invention, a display means for visually displaying a graphic, an input means for inputting data such as an angle and a size for determining the shape of the arrow, and an arrow based on the data input from the input means. Since it has a means for outputting to the display means,
The present invention provides an excellent data processing device that allows an operator to freely set an arrow pattern.
