Abstract

PURPOSE:To increase the degree of freedom in edition and to improve operability by setting up an origin to be the center of edition to an optional position and displaying the set position by a specific graphic. CONSTITUTION:A user selects a rectangle 15 by using a mouse 22, inputs an expanding function from a keyboard 21 and moves the mouse 22. A specific graphic 16 is always displayed in the rectangle 15 on the screen of a CRT 27 and is moved in accordance with the movement of the mouse 22. When the position of the graphic 16 is determined, a CPU 20 changes the data of the graphic 16 stored in a memory 28 to a determined coordinate value and substitutes the coordinate value of the graphic 16 for the coordinate value of the origin for the expanding processing of the graphic. When the position of a guide point 18 is determined by moving the mouse 22, the CPU 20 expands the rectangle 15 around the graphic 16 in accordance with the moving position of the guide point 18. Thereby, the degree of freedom in edition is increased and the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation device for creating documents consisting of characters, graphics, etc., and particularly to a document creation device for creating graphics.

[Conventional technology]

Conventionally, such document creation devices have been used in workstations, word processors, etc., and when creating a document containing a mixture of characters and figures, there is a space for creating characters,
I divided the area for creating figures into separate areas on the Mi window and worked on them. When drawing a figure, the figure is drawn by drawing a line or rectangle within the area of the figure, or a complicated figure is drawn by combining each figure.

Also, each figure has control points in advance, for example, 4 if it is a rectangle.
For a circle, there are four points on the top, bottom, left and right, and for a straight line, there are two end points. ) is set.

For example, as shown in FIG. 4, if a desired rectangle 10 is selected by pointing it with a pointing device such as a mouse (not shown), and an enlargement function is instructed using an instruction means such as a keyboard, the cursor position is The closest control point becomes the guidance point 12, and the control point located farthest from the guidance point 12 becomes the origin (fixed point) 11. In this way, the origin 11, which is the center of editing, and the guide point 12, which indicates how far to enlarge, are determined. Then, the user uses the mouse to move and confirm the guide point 12 to an arbitrary position, thereby performing an enlargement process according to the moved position of the guide point 12.

[The invention tries to solve the F! However, with the above device, when an editing angle such as enlargement is specified, the editing origin is determined only in one direction. Therefore, the origin cannot be set freely, it is impossible to perform deformation at an arbitrary position, and there is a problem that operability is poor. Further, since the origin, which is the center of enlargement, is displayed on the figure, there is a problem that it is difficult to distinguish it in complex figures.

The present invention was made in view of the above-mentioned problems, and allows the origin, which is the center of the B collection, to be set at a free position, and also increases the degree of freedom of the G collection by making it easier to determine the origin. An object of the present invention is to provide a sentence creation device that can improve operability.

[Means and effects for solving the problem] In the present invention,
Display means such as a display device for displaying special figures;
a storage means such as a memory for storing the position of the special figure;
Edit 51 the movement instruction means such as a mouse that instructs the movement of the special figure and the movement position of the special figure! ! and a position determination means such as CPLI which determines the center of the desired figure and the origin of coordinates, and when a user instructs a predetermined editing process such as enlargement when editing a desired figure,
CPLI determines and replaces the origin of the figure that is the countercolor of the editing process (the center of the drawing process such as enlargement) with the movement position of the special figure specified by the mouse, thereby changing the origin of the figure. Like the guide point, it can be easily moved to any position. By moving the guide point of the above figure to an arbitrary position and fixing that position, the specified editing 5I! 1% is done.

〔Example〕

Embodiments of the present invention will be described in detail based on the drawings of FIGS. 1 to 3.

FIG. 1 is a block diagram showing a schematic configuration of a document creation device according to the present invention. In the figure, a keyboard 21 and a mouse 22 connected to the keyboard 21 input various data and commands.
It's called J. >20, predetermined performance, processing, etc. are executed in parallel according to the program corresponding to the input command.

External storage ffi device (hereinafter referred to as "disk device")
23 is a program that manages the data (document) to be edited and the position of a special figure related to the present invention, which will be described later, and a program that extends or enlarges the figure by replacing the moving position of the special figure with the position of the origin of the figure. Contains various programs including.

The character information storage section 24 is made up of a RAM and temporarily stores data, encyclopedias, etc. The data of the special figure according to the present invention is stored in advance in the buffer 7 memory 28 from files stored in the disk device 23. The buffer 1 memory 28 stores the data of the above-mentioned special figure in C.
It is stored in a table format as coordinate values in the X direction and y direction on the screen of the RT 27. In addition to the above data, the buffer memory 28 also stores data on an origin set on the figure and a guide point for extending or enlarging the figure. As mentioned above, when setting the origin, normally when a predetermined function key for figure processing is pressed, the control point that is farthest from the guide point set on the figure changes and is determined as the origin. Since the position of the origin must be determined before the guide point is determined, the position of the origin of the graphic is set using the mouse 22 based on the user's instructions, and is stored in the buffer 1 memory 28. Note that the coordinate values of the special figure and the guide point are updated as they move.

The font ROM 25 stores multiple types of character fonts, and the CPtJ 20 stores character dots corresponding to input data from the keyboard 21 etc. in the font ROM 2.
5 and controls the CRT drive circuit 26 to display corresponding character dots on the CRT 27, which is a display device.

Further, on the screen of the CRT 27, a branch window (not shown) of the selected relationship is displayed.

The above-mentioned Bunshi consists of a collection of characters like a sentence and a collection of figures like dots and lines, and as mentioned above, character dots corresponding to input data from the keyboard 21 etc. are drawn from the font ROM 25. It is possible to read out and perform editing operations such as adding or correcting the branch in the branch window. Each figure can be drawn within a figure frame displayed within the Bunshi window.

Therefore, when drawing a figure, insert a figure frame within the bungata.

Next, the operation of the figure enlargement process according to the present invention will be explained based on the flowchart of FIG. In the embodiment, a process for enlarging a rectangle shown in FIG. 3 will be described.

The user uses the mouse 22 to select the
When rectangle 15 is specified and selected (step 101),
CPIJ20 recognizes the controlled object.

A special figure 16 having a special shape shown in FIG. 3 is always displayed on the screen of the CRT 27. Then, an enlargement function is input from the keyboard based on the user's instructions (step 102), and the special figure 16 is moved as the mouse 22 is moved by the user's operation, so that the position of the special figure 16 desired by the user is Decide on any position. When the position of the special figure 16 is determined, the CPU 20 changes the data of the special figure 16 stored in the buffer 1 memory 28 to the determined coordinate values, and also changes the coordinates of the origin of the enlargement process of the figure. value to special figure 1
Replace with the coordinate values of 6. Next, when the user moves the mouse 22 to specify and determine the position of the guide point 18, in step 104), the CPU 20 moves the mouse 22 to the origin of the figure displayed on the CRT 27, that is, the special figure. The rectangle 15 is enlarged according to the movement position of the guide point 18 determined by the movement of (step 1
05).

Therefore, according to the present invention, the position of the origin on the figure can be replaced with the position of the special figure so that they completely match, so that the user can arbitrarily set the origin and display it. Furthermore, in the present invention, since the origin of the figure can be displayed using the special figure, the position of the origin can be easily determined.

In this embodiment, the rectangular enlarging process has been described, but the present invention is not limited to this, and can of course be applied to graphic processing of all types of figures. In addition, the present invention is capable of expanding, reducing,
It can also be applied to graphic processing using rotational functions. It is also possible to apply it to drawing and editing by specifying numerical values using a special figure as the origin.

[Effects of the Invention] As explained above, in the present invention, the special figure is moved and its position is determined, and the position of the origin of the desired figure is replaced with the position of the special figure to match. The origin, which is the center of the image, can be set at any position, and the origin can be easily determined, increasing the degree of freedom of the 8 series, and improving operability.
