Abstract

PURPOSE:To distinguish between selected vector data and the other vector data at a glance by selecting objective vector data among displayed vector data and changing the classification and the thickness of its line. CONSTITUTION:A selecting means 1 has a keyboard and a mouse 11, and the position and the length of a graphic to be displayed are converted into a signal or a numerical value and is sent to a converting means 2. This sent signal or numerical value is converted into vector data by the converting means 2 and is operated by an operation means 3 and is stored. The operation means 3 operates exclusive OR between converted vector data and original vector data and increases the thickness of the result n times (n>1, preferably, n=3). The operation means 3 generates vector data on the inside and the outside of vector data resulting from exclusive OR and transfers them to a display means 4. This vector data is displayed again in the same position as original vector data on the display means 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vector data discriminating display device, and more particularly to vector data for discriminating display from other vector data by selecting a specific one from a plurality of vector data displayed on a screen. Distinguishing display device.

[0002]

2. Description of the Related Art In a conventional vector data distinguishing display device, a straight line selected as shown in FIG. 3A is used as a method of displaying selected vector data separately from other unselected vector data. The circumscribed rectangle 40 is displayed for 31 vector data, or
The vector data of the selected straight line 32 shown in (B) is created by changing the line type (hereinafter referred to as line type), and the exclusive OR of the vector data and the selected vector data 32 is obtained. The resulting vector data 33 was displayed as shown in FIG.

[0003]

In the above-described conventional vector data distinction display device, when the rectangle 40 circumscribing the selected vector data 31 is displayed and distinguished as shown in FIG. There is a problem in that it is not possible to visually recognize the selected vector data and the unselected vector data if the circumscribed rectangle vectors are the same even if the shapes are different. For example, a straight line 34 of the same length intersecting the straight line 31 of FIG.
When is selected, the circumscribing rectangle 40 is the same as that in FIG. 3A as shown in FIG. 3D, so it is necessary to distinguish which of the straight line 31 and the straight line 34 is selected. I can't.

On the other hand, as shown in FIGS. 3B and 3C, after changing the line type of the selected vector data 32, the exclusive OR of the selected vector data 32 and the selected vector data is taken and the result 33 is obtained. When displaying and distinguishing, when the line type of the selected vector data does not differ much from the line type of the result of exclusive ORing with the selected vector data after changing the line type. Has a problem that it is not easy to visually recognize whether it is selected or not. For example, when the straight line 35 of FIG. 3 (E) is selected, this straight line 3
When the exclusive OR of 5 and the straight line 36 with a different line type is taken, the result becomes a straight line 37, and there is not much difference between the straight line 35 and the straight line 37, and it is distinguished whether or not the straight line 35 is selected. It's not easy to do.

[0005]

A vector data distinguishing and displaying device of the present invention comprises a selecting means for selecting a specific one of a plurality of vector data displayed on a screen, and a line for the selected vector data. The conversion means for changing the seed and the exclusive OR of the selected vector data and the vector data after the line type conversion are taken, and the thickness of the result is multiplied by n (n>
1, preferably n = 3), and display means for displaying vector data whose thickness is n times as large.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings.

Referring to FIG. 1, a vector data distinguishing and displaying device according to an embodiment of the present invention includes a selecting means 1, a converting means 2, a computing means 3 and a displaying means 4.

The selecting means 1 has a keyboard and a mouse 11, and sends the position or length of the graphic to be displayed on the converting means 2 in the form of a signal or a numerical value. The transmitted signal or numerical value is converted into vector data by the conversion means 2, calculated by the calculation means 3 and stored. The stored vector data is displayed on the display means 4 in the form of lines or dots.

The operation of this embodiment will be described with reference to FIG. Here, as shown in FIG. 2A, the circle 2 is displayed on the display means 4.
Consider a case where four vector data of 1, a rectangle 22, a triangle 23, and a straight line 24 are displayed, and the triangle 23 is displayed separately from other vector data 21, 22, and 24.

First, when the triangle 23 is designated by using the mouse 11 of the selecting means 1 by the arrow 28 in FIG. 2B, the transforming means 2 uses the vector data stored based on the designated position to form the triangle vector. The data is taken out, the line type of the vector data is converted from a solid line to a dotted line, and the data is stored again. Next, the calculation means 3 takes the exclusive OR of the converted vector data and the original vector data. Further, the calculating means 3 produces vector data inside and outside of the vector data resulting from the exclusive OR, and passes it to the display means 4. The display means 4 redisplays this vector data 23a at the same position as the original vector data as shown in FIG. 2 (C).

As a result of the above processing, the selected triangle vector data 23a is displayed three times thicker than the other vector data 21, 22 and 24 as shown in FIG.
You can see that it was selected at a glance.

[0012]

As described above, according to the present invention, the target vector data is selected from the already displayed vector data, and the type and thickness of the line are changed while the shape of the vector data remains unchanged. It is possible to efficiently discriminate whether or not the selected vector data is the target vector data at a glance. Also, the exclusive OR is 2
If you repeat it, it will return to the original, so you can easily cancel the selection.
