Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] In an image processing device that performs coordinate movement processing for coordinate values input from a tablet device, only the x-axis for the character coordinate values input when a predetermined mode is set. By providing the character offset adding means for adding the offset amount Δx in the direction and the offset amount Δy in the y-axis direction, the input positions of the graphic mode and the character mode are not rounded to the same point.

[Industrial application field]

The present invention relates to a character arrangement device of a graphic processing device.

[Prior Art] FIG. 3 (a) is a diagram showing an example of a graphic processing system having a conventional tablet device.

In the figure, 1 is a graphic processing device, 2 is a coordinate input device (tablet device), 2a is a tablet screen, 2b is a stylus pen, and 2c is a control unit. The same symbols represent the same objects throughout the drawings.

In the graphic processing system, the tablet device 2 is conventionally used to input a graphic. The tablet device 2 is composed of a tablet screen 2a, a stylus pen 2b, and a control unit 2c, and is connected to the graphic processing device 1.

The operator uses the stylus pen 2b to display the tablet screen 2a.
When the arbitrary point above is hit, the control unit 2c obtains the coordinate value of the hit point and outputs the coordinate value to the graphic processing device 1.

Therefore, the operator can place a drawing on the tablet screen 2a and hit each point on the drawing with the stylus pen 2b to input a graphic into the graphic processing apparatus 1.

FIG. 3 (b) is a diagram showing an example of a conventional graphic processing apparatus.

In the figure, 3 is an input mode designation key, 10 is a control unit, 11 is an interface unit, 12 is a drawing work file, 13 is output means,
Reference numeral 14 is a display screen, 15 is a line segment creating means, 16 is a character creating means, 17 is a coordinate movement processing means, and 18 is an input means.

The conventional graphic processing device has the configuration shown in FIG. 3 (b), and the interface section 11 is a part constituting an interface with the tablet device 2, and the coordinate value sent from the tablet device 2 is the interface. Graphic processing device 1 via unit 11
Entered in.

All the various image data created by this figure processing device are created on the drawing work file 12 and the drawing work file is created.
The image data on 12 is displayed on the display screen 14 via the output means 13.

Whether the input data is a character or a graphic is first designated by the input mode designation key 3.

If the created data is a figure, the line segment creating means 15 is activated to create various figures on the drawing work file 12 by the line segment. For example, a straight line graphic is created on the drawing work file 12 by designating the coordinates of both ends, and a circle graphic is created on the drawing work file 12 by designating the coordinates and radius of the center point. Input is made via the unit 11 or from the input means 18.

If the created data is a character, the character creating means 16 is activated to create various characters on the drawing work file 12. A specified character is selected from a character data file (not shown) that stores vector character data of each character and is arranged at the coordinate position specified by the tablet device 2.

FIG. 4 is a diagram showing an example of a grid group on the tablet screen.

FIG. 5 is an explanatory view of a display when a conventional figure / character is input.

In the figure, G _{1 to} G _n are grids, and P and Q are input points.

On the tablet screen 2a, a plurality of grids G _{1 to} G _n are usually arranged at certain fixed intervals vertically and horizontally, and the value of these intervals can be set to an arbitrary value, for example, 10 mm. Note that these grids G _{1 to} G _n are invisiblely provided on the tablet screen 2a.

When the stylus pen 2b hits an arbitrary point P (indicated by X) on the tablet screen 2a, the control unit 2c outputs the coordinates (x _P , y _P ) of the point P to the graphic processing device 1.

At this time, the graphic processing device 1 does not adopt the coordinates (x _P , y _P ) received from the tablet device 2 via the interface unit 11 as they are, and activates the coordinate movement processing means 17 to move to the point P. The closest grit G _N is obtained, and the drawing work file 12 is set with the coordinates (x _N , y _N ) of the grit G _{N as} the coordinates of the point P.
May be written to.

Coordinates moving processing means 17 hit as described above _(x P, _{y P),} and the closest grid _{G N} coordinates _(x N, _{y N)} so converting (rounding), for example,
It is very convenient when drawing parallel lines.

[Problems to be solved by the invention]

However, when the figure processing device 1 has the coordinate movement processing means 17, when a figure and a character are hit at the same input point on the tablet screen 2a, both are rounded to the same grid G _N closest to this input point. Be done.

Characters as shown in FIG. 5 as an example (ABC) is hit a point P close to the grit G _N, graphics (underline)
Also when it is hit Q other points close to the grid G _N, for moving the point P to the point Q is also both the same grit G _N by the coordinate moving process unit 17, too close overlapping characters and graphics,
It had the drawback of being difficult to see.

[Means for solving problems]

As shown in the principle diagram of FIG. 1, the above problem is caused by a plurality of predetermined coordinate points (x _G , y _G ) with respect to the input coordinate points.
The coordinate movement processing means 17 for detecting the closest coordinate point (x _N , y _N ) among the coordinate input devices 2 is used to convert the input coordinate (x _P , y _P ) from the coordinate input device 2 into the coordinate point (x _N , y _In the character arranging device of the graphic processing device for performing coordinate movement to _N ), the means 30 for identifying whether the processing mode of the graphic processing device 1 is the character processing mode or the graphic processing mode, and the coordinate point It is solved by providing the variation means 20 which performs variation of the coordinate point (x _N , y _N ).

[Action]

According to the present invention, the variation means 20 operates according to the mode identified by the mode identification means 30, and the input coordinates (x _P ,
y _P ), the variation processing is performed on at least one coordinate value for the most recent coordinate point (x _N , y _N ). Therefore, even when the input coordinate of the character and the input coordinate of the figure are at the same position,
Figures and characters are displayed slightly separated.

〔Example〕

An embodiment of the present invention is shown in FIG. 2 (a) based on the principle diagram of the present invention in FIG.

FIG. 2 (b) is a flowchart.

In the figure, 20 is a variation means and 30 is a mode identification means.

When the coordinates are input from the tablet device 2, the figure processing device 1 drives the coordinate movement processing means 17 to perform the rounding processing, and then activates the mode identifying means 30. Mode identification means
30 is the line segment creating means 15 in operation (in figure creation mode)
Or whether the character creating means 16 is operating (in the character creating mode).

If it is in the character creation mode, the variation means 20 operates to add an offset to the input coordinates (x _N , y _N ) after the rounding process to change to (x _N + Δx, y _N + Δy). I do. If it is in the figure creation mode, the variation means 20 does not operate and the offset is not added to the input coordinates (x _N , y _N ) after the rounding process.

When coordinates are input from the tablet device 2, the graphic processing device 1 according to the present invention operates according to the flowchart of FIG. 2 (b).

Specify the mode.

There is an input (coordinates) from the tablet device 2.

The control unit 10 of the graphic processing device 1 activates the coordinate movement processing means 17 to perform rounding processing on the input coordinates.

The mode identifying means 30 checks whether the mode is the graphic creation mode or the character creation mode.

In the character creation mode, the variation means 20 operates to add an offset to the input coordinates (x _N , y _N ) after the rounding process,
The coordinate value is changed to (x _N + Δx, y _N + Δy), and the process ends.

If it is in the figure creation mode, the variation means 20 does not operate and ends immediately.

As a result, the input position of the character on the display screen is displaced by the offset.

In the above description, the variation means 20 adds the offsets in both the x-axis direction and the y-axis direction, but it is not always necessary to add the offsets in both the axes, and in some cases, only in the x-axis direction or y. It is also possible to add an offset only in the axial direction.

〔The invention's effect〕

As described in detail above, according to the present invention, since a graphic and a character are input, even if the same input point is hit, the position of the character is slightly displaced, and it is possible to easily arrange the character that is easy to see. It has a great effect.
