Abstract

PURPOSE:To execute a deforming operation by only a moving instruction from an instructing device, and to simplify the operation by giving an attribute of a free point or a fixed point to an arbitrary point in a graphic pattern. CONSTITUTION:The designation of an attribute by an attribute designating part 4 is executed by instructing a point on a graphic pattern by a tablet 1, and inverting the present attribute. For instance, apexes A, B and C are set as fixed points, an apex D is set as a free point, and when the tablet 1 is moved to a desired position, coordinate information is inputted to a moving extent detecting part 2, a moving distance of a pen is detected, and it is sent to a coordinate converting part 3. The coordinate converting part 3 reads out a point which has been designated as a moving point from a graphic data stored in a graphic data store part 5, adds (subtracts) a moving extent, and stores it again to the graphic data store part 5. In this way, a deforming operation can be executed easily to an arbitrary point without using a command of movement, enlargement/reduction, deformation, etc.

Description

[Detailed Description of the Invention] [Overview] Conventionally, in a device for editing a figure using a mouse or a tablet, when moving, enlarging/reducing, deforming, etc.
In order to solve the problem of complicated operations because the function must be reselected for each process, the pointing device It is simplified so that transformation operations can be performed simply by moving instructions from .

[Industrial Field of Application] The present invention relates to a graphic editing device, and more particularly to an interactive graphic editing device that repeatedly processes and corrects a graphic that has been input once.

Conventional graphic editing devices are designed for specialized operators, and the pursuit of rich functionality makes operations complicated and difficult for amateurs to use.

That is, since the operation procedure differs depending on the function, there are problems with the user interface, such as having to memorize the operation method for each function, and the operation method being difficult to remember because it is not intuitive.

Especially these days, computers are not used by some experts,
Since it has come to be widely used by general non-specialists, there has been a strong desire for a graphic editing device with simple specifications that allows a variety of operations to be performed using an intuitive and simple combination of functions.

[Conventional technology] Conventional graphic editing devices have the ability to "move", "transform", and "enlarge/enlarge".
Functions such as "zoom out" were switched by selecting a menu or icon for each function.

That is, in the conventional method, when performing operations such as ``move'', ``enlarge/reduce'', and ``transform'' a figure, (1) first select an icon or menu for each processing function;
2) Next, it was common to select a target pattern, and (3) then specify a destination etc. for processing.

[Problems to be solved by the invention] With the conventional method of preparing commands for each function, it is difficult to intuitively understand the functions of the commands.

■Commands are difficult to remember because there is no organic relationship between them.

■The number of commands increases in proportion to the type of command.

There was a problem.

The present invention aims to provide a new graphic editing method that solves these conventional problems.

[Means for Solving the Problems] FIG. 1 shows a block diagram of the principle of the graphic data embroidery collection method of the present invention.

In the mouth, 1 is a coordinate indicating means such as a mouse or a tablet, and 2 is a movement amount detecting means for detecting the amount of movement of the indicating means 1.

Reference numeral 4 denotes an attribute specifying means for specifying an attribute indicating whether or not a given point in the pattern moves with the movement of the indicating means 1.

Reference numeral 3 denotes a coordinate conversion means for converting the coordinates of a point specified as a moving point by the attribute specifying means 4 based on the movement amount of the instruction means 1 detected by the movement amount detection means 2.

[Operation] By adopting the above configuration, the point designated as a "free point" moves as the indicating means (1) moves, and the point designated as a "fixed point" moves as the indicating means (1) moves. saves its position regardless of its movement.

That is, when the coordinate point (Xi, Yi) is specified as a free point, it is converted to (Xi+ΔX, yt+Δy) according to the movement amount (ΔX, Δy) of the indicating means (1), and
When the coordinate point (Xi, Yi) is specified as a fixed point, (Xi.

Yi) remains unchanged.

However, when only one fixed point is specified, the coordinates are not converted to add the amount of movement to the coordinates of each moving point, but instead the coordinates are converted to correspond to the moving angle around the fixed point of the indicating means (1). It is also possible to adopt a configuration in which coordinate transformation is performed so as to rotate the graphic pattern, or to perform enlargement/measure according to a change in the distance from the fixed point to the indicating means +1).

Thereby, it is possible to simply perform a transformation operation on an arbitrary point without using commands such as "move" and "enlarge/fi small j, r transformation".

[Example] The present invention will be described in more detail below with reference to Examples shown in FIGS. 2 to 9.

FIG. 2 is a block diagram of one embodiment of the present invention.

In the figure, numerals 1 to 4 indicate components having the same functions as those in FIG. This is a display section for displaying information.

The operator centralizes the attributes of points within the graphic pattern according to the type of deformation or movement of the graphic pattern.

The attribute specification unit 4 specifies an attribute by specifying a point on the graphic pattern using the tablet 1 and inverting the current attribute. That is, by specifying a point on the graphic pattern using the tablet 1 and pressing the switch SW1 on the tablet, the currently fixed point becomes a moving point.
What was a moving point is reversed to a fixed point.

FIG. 3 is a diagram showing an example of storage of graphic pattern data in this embodiment.

In the figure, the pattern code in the first column is a code indicating the type of figure, such as a triangle or quadrilateral, and the second column stores the number of strokes.

3rd to 5th @ are the coordinate data of each vertex (X+, Yi).

(X2. Y2 ), (X3. Yl ), and
(The most significant bit of 'h has attributes (Pl, P2゜P3)
Remember. For example, "O" indicates a fixed point, and "1" indicates a moving point. The last delimiter indicates the end of this pattern data.

Next, the operator presses the switch S-2 on the tablet 1 and moves it to a desired position.

A part of the coordinate information sent from the tablet 1 is input to the movement amount detection section 2, and the movement distance of the pen (ΔX) is input to the movement amount detection section 2.

Δy) is detected and sent to the coordinate transformation section 3.

The coordinate conversion unit 3 converts the point (Xi, Y
i), and add (subtract) the movement amount (ΔX, Δy) sent from the movement amount detection unit 2 to obtain (Xi+ΔX,
Yi+Δy) and stored in the graphic data storage unit 5 again.

FIGS. 4 to 1) are diagrams showing examples of graphic pattern correction processing according to the present invention.

For the sake of simplicity, these processing examples use a quadrilateral composed of vectors of four points as an example, but similar processing can be performed for other figures.

FIG. 4 shows a rectangle (A, B) for graphic processing.

It shows the process of switching the specific point (D) of C and D) from a fixed point to a moving point. As mentioned above, switching can be easily instructed using the tablet l. In the figure,
(•) indicates a fixed point, and (0) indicates a moving point.

FIG. 5 is a diagram showing an example of processing for moving the vertices of a figure. In this case, it is sufficient to set the vertices A, B, and C as fixed points (.), set only the vertices as free points, and move the pointing device.

FIG. 6 is a diagram showing an example of processing for enlarging/reducing in the horizontal direction. In this case, the vertices A and B may be set as fixed points, the vertices C and D may be set as free points, and the pointing device may be moved in the horizontal direction.

FIG. 7 is a diagram showing an example of processing for vertically enlarging/reducing. In this case, set vertices B and C as fixed points,
The vertices A and D may be set as free points and the pointing device may be moved in the vertical direction.

FIG. 8 is a diagram illustrating an example in which tilt processing is performed in an application example in the case of two free points. The difference between Figures 6 and 7 is the direction of movement of the pointing device with respect to the free line segment (line segment formed by connecting free points); in this case, it is moved parallel to the free line segment. .

FIG. 9 is a diagram showing an example of transformation processing when three points are free points. Basically, this is the same as the vertex movement shown in FIG.

FIG. 10 is a diagram showing an example of movement processing. in this case,
All points are designated as free points, so the shape does not change shape, but the position of the shape moves.

Figure 1) is a diagram showing an example of rotation processing. This is the 9th
Another solution to the case where the three points in the figure are free points, and if there is only one fixed point, the transformation shown in Figure 9 is not performed, but the coordinates are adjusted so that the figure is rotated by the angle that the tablet 1 has moved. It is something that converts.

FIG. 12 is a diagram showing an example of enlargement/reduction processing.

This is another solution when the three points in Figure 9 are free points, and if there is only one fixed point, the transformation shown in Figure 9 is not performed and the tablet 1 is moved from the fixed point. Distance r4Q to the first indicated point and distance Q゛ to the current indicated point
Coordinate transformation is performed so that the image is enlarged/reduced at an enlargement/reduction ratio determined by the ratio of .

When only one fixed point is specified, it may be determined whether to transform, rotate, or enlarge/reduce, or it may be configured so that it can be switched by specifying the mode. .

[Effects of the Invention] As explained above, according to the present invention, (1) It is specified whether or not the points constituting the figure move with the pointing device. ■Move the indicating device. Since a figure can be transformed or moved just by combining the two operations, intuitive and easy-to-understand figure editing can be obtained, which has a great practical effect.
