Abstract

PURPOSE:To easily obtain distance between click points a user requires by making the coordinate standard value of a figure the user requires capable of being set freely. CONSTITUTION:A map to show from some click point 111 to some destination of the click point 114 is displayed on the screen 1 of a graphic device 2 in a railway station. The click points 111, 112, 113, 114 are points clicked on the screen 1 by a mouse 3. At the time of clicking by the mouse 3, at first, length between the click points 111 and 112, next, the length between the click points 112 and 113, and then, the length between the click points 113 and 114 are obtained by calculating coordinates on a graphic memory 103. If by setting one coordinate to be 1m, the length from the click point 111 to the click point 114 is 256, the actual distance is 256m, and this is displayed on a display area 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graphic processing method, and more particularly to a graphic processing method for displaying a graphic on a graphic screen and determining the coordinates of the graphic required by a graphic user.

[Conventional technology]

In conventional figure processing methods, the coordinates on the graphic memory for drawing are set in a coordinate system specific to the graphic memory, so the size of the figure displayed on the graphic screen does not correspond to the actual value. Therefore, it was extremely difficult to determine the actual distance to be used from the figure displayed on the graphic screen.

[Problem to be solved by the invention]

In the conventional figure processing method described above, the size of the figure displayed on the graphic screen does not correspond to the actual value to be used, and it is not possible to calculate the actual distance to be used from the figure displayed on the graphic screen. It has the following drawbacks.

[Means to solve the problem]

The graphic processing method of the present invention includes a coordinate reference value setting mechanism that sets a coordinate reference value indicating an actual distance using one coordinate on a graphic memory with respect to a coordinate system of graphic processing for drawing and displaying a figure; A click coordinate acquisition mechanism that acquires the coordinates of the clicked position by clicking any position of the displayed figure with a mouse, and a coordinate distance that calculates the coordinate distance between the plurality of coordinates acquired by the click coordinate acquisition mechanism. a calculation mechanism; an actual distance calculation mechanism that calculates an actual distance by multiplying the coordinate distance calculated by the coordinate distance calculation mechanism by a coordinate reference value for one coordinate set by the coordinate reference value setting mechanism; and the actual distance. The apparatus includes an actual distance display mechanism that displays a value indicating the actual distance calculated by the calculation mechanism on a graphic screen on which a figure is drawn.

〔Example〕

Next, an embodiment of the present invention will be described with reference to screens.

FIG. 1 is a block diagram showing an embodiment of the graphic processing method of the present invention.

Further, FIG. 2 is a conceptual diagram showing an example of drawing by the graphic processing method of this embodiment. As shown in FIG. 2, the graphic processing method of this embodiment is a graphic family that draws a graphic screen 1! 2, a mouse 3 used to click a position on a figure, and a keyboard 4 used to input characters.

The graphic screen 1 shows click points 111, 112 degrees 113.1 indicating the positions clicked with the mouse 3.
14, an inter-click connection line 12 connecting the positions clicked with the mouse 3, and a display area 13 in which the actual distance required for use is displayed. Here, it is shown that a click point 111 is used as a starting point for measuring the actual distance, and a click point 114 is used as an ending point to calculate the distance therebetween. In reality, click point 111 indicates a railway station, and click point 114 indicates a destination location.

As shown in FIG. 1, the graphic processing method of the embodiment includes a graphic processing mechanism 101 that controls the second graphic device 2, and a graphic processing mechanism 101 that performs drawing on the graphic screen l of the graphic device 2. a mechanism 102, a graphics memory 103 of the graphics device 2,
An input mechanism 104 for inputting reference values of the actual coordinates to be used from the keyboard 4; a coordinate reference value setting mechanism 105 for setting a coordinate reference value indicating the actual distance to use one coordinate on the graphic memory; A click coordinate acquisition mechanism 106 that acquires the clicked coordinates from the graphic memory 103; a coordinate distance calculation mechanism 107 that calculates the coordinate distance between the acquired coordinates; and a coordinate distance calculation mechanism 107 that calculates the coordinate distance between the acquired coordinates. Reference value setting mechanism 105
The actual distance calculating mechanism 108 calculates the actual distance to be used by multiplying it by the coordinate reference value set in , and the drawing mechanism 102 displays the value of the calculated actual distance to be used on the graphic screen 1 of the graphic device 2. It has an actual distance display mechanism 109 that is displayed in the display area 13 of.

As shown in FIG. 2, the graphic processing method of this embodiment starts from click point 111, which is a railway station, to click point 1
A map showing up to the destination location 14 is drawn and displayed on the graphic screen 1 of the graphic device 2. Here, it is necessary to know the actual distance from the click point 111, which is the station, to the click point 114, which is the destination location. Since the line from click point 111 to click point 114 is not a straight line, there are click point 112 and click point 113 as curved positions.

Click points 111, 112, 113, and 114 are points clicked with the mouse 3 on the graphic screen 1 of the graphic device 2. If mouse 3 is clicked, first the length between click points 111 and 112, then the length between click points 112 and 113, and then the length between click points 113 and 114. The distance can be determined by calculating the coordinates on the graphic memory 103. In this embodiment, before drawing and displaying a map on the graphics screen 1 of the graphics device 2, it is necessary to set a coordinate reference value of the actual length to be used for one coordinate in the graphics memory 103. For example, 1
By setting the coordinates to 1 meter, click point 1
The length from 11 to 114 is a graphic memo! 71
If the length as a coordinate on 03 was 256, the actual distance to utilize would be 256 meters.

Once the actual distance has been determined, it is necessary to display the value on the graphic screen l of the graphic device 2, and it is displayed in the display area 13.

As described above in the embodiment, the figure processing method of this embodiment allows the user to freely set the coordinate reference values of the figure he or she needs by making settings specific to the user. The required distance between click points can be easily determined.

〔Effect of the invention〕

As explained above, the graphic processing method of the present invention has the effect that the distance between the actual points to be used can be easily determined from the graphic displayed on the graphic screen for determining the distance in the coordinate system. ing.
