Description

TECHNICAL FIELD The present invention relates to a method of inserting character string data into an enclosure on the coordinates of graphic data handled by a computer or the like applied to map creation or the like.

<< Prior Art >> Conventionally, in a computer or the like, a graphic such as a map is handled as numerical data, that is, it is converted into numerical data by fitting the graphic on a predetermined standard coordinate,
It is handled as graphic data on such coordinates.

For example, the applicant of the present invention transmits and distributes electric power to each house by contract, and therefore, for grasping and managing the electric power,
Distribution status is mapped on a computer. That is, FIG. 8 is a perspective view showing an example of such a graphic display on a computer, but as shown in the figure, on the computer, only the outline such as a house frame is left from map information such as an aerial photograph and the graphic data is left. In addition to creating the, the character string data such as the contract name holder is inserted into each of these house frames to make a so-called distribution map,
The character string data is appropriately updated and used for customer service.

<< Problems to be Solved by the Invention >> However, in such an application system for creating maps, the characters are inserted so as to follow the direction of the figure (house frame). It is possible. In other words, the characters are not necessarily parallel to the axes of the Cartesian coordinate system in the image, and the characters can be arranged in any direction in the image. The horizontal axis of the system) is not preset. Therefore, when inserting (updating) the character string data, the operator must set the arrangement direction of the character string, the size of the character, etc. each time.
In addition, in the case of a map, since it is necessary to insert and arrange the character string data in the house frame in a well-balanced manner, the operator of the computer concerned can display the coordinate position, size, and
The specifications such as the shape must be inspected, and correspondingly, the specifications such as the coordinate position and size of the character string data must be designated one by one, which causes a problem that the pointing operation is troublesome and troublesome.

The present invention has been made in view of the above background, and is preferably applicable to automation of character string data insertion so as to simplify the instruction operation, and provides a method for inserting character string data that can improve convenience. The purpose is to do.

<Means for Solving the Problem> In order to achieve the above object, the present invention is such that a figure such as a map and characters are mixed, and an arbitrary tilt direction is provided in an irregularly shaped enclosure according to the orientation of the enclosure. In the method of inserting the character (character string data) in the computer system which allows the arrangement of the character string data, first, the longest side of the surrounding frame is obtained. Then, vertical writing or horizontal writing as the notation method of the character string is determined from the inclination of the longest side, and a part of the outer periphery is in parallel with the longest side and is in contact with the surrounding frame and is located in the surrounding frame. Thus, the substantially rectangular character frame is set, and the character size is appropriately determined according to the size in the character frame. Then, predetermined character string data is inserted into the character frame based on the determined notation method and character size.

<< Operation >> First, the longest side of the surrounding frame (house frame) is obtained. Then, since the arrangement direction of the surrounding frame is detected, horizontal writing / vertical writing is determined based on the inclination angle in order to efficiently insert the character string. That is, for example, if the inclination angle is small with respect to the horizontal direction, horizontal writing is suitable, and if the inclination angle is large, vertical writing is performed. Further, a rectangular character frame is set so as to meet a predetermined condition, a character size is determined so that a character string can be arranged in the character frame with good balance, and the character string is inserted and arranged in the character frame. Then, since the character frame exists in the surrounding frame and is parallel to the arrangement direction of the surrounding frame (longest side), the character string data is efficiently and surely inserted into the surrounding frame. That is, the entire character string data is optimally matched within the enclosure, and by inserting the above method into a soft program, the insertion of the character string data is automated.

<< Embodiment >> An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 (A) to (D) are flow charts schematically showing a preferred embodiment of the present invention. 2 to 4 are conceptual diagrams for explaining the flowchart of FIG.

The present invention is basically a method of inserting character string data in an irregularly shaped box on the coordinates of graphic data handled by a computer, etc. Character string data is arranged along the direction, and the character size is appropriately determined according to the size of the surrounding frame in the longest direction. Software for creating a so-called power distribution map described in the conventional art. Prepared for the program and implemented specifically.

As shown in FIG. 1 (A), first, the house frame data as the surrounding frame is read (S1), and the coordinate specifications of the character frame, which is the portion where the character string data is inserted, are calculated (S2). That is, FIG. 2 is a conceptual diagram of house frame data, and as shown in FIG. 2, the house frame data F is an enclosure frame in which the sides a1 to a4 are connected.

Here, as shown in FIG. 1 (B), the longest side a1 and its inclination angle θ are obtained (S21). Next, the arrangement direction of the character string data, that is, either the vertical writing direction or the horizontal writing direction is determined from the tilt angle θ (S22). In the present embodiment, vertical writing is used when the tilt angle θ is 45 degrees or more, and horizontal writing is used when the tilt angle θ is less than 45 degrees.

On the other hand, from the midpoint A1 of the longest side a1, a perpendicular line b1 is drawn in the house frame data F (S23), and a parallel line b2 is drawn to the longest side a1 through the midpoint A2 of the perpendicular line b1 (S24). Then, the midpoint of the parallel line b2 is set as the center point C of the character frame (S25). The parallel line b2 is the center line of the character frame.

After calculating the coordinate specifications of the character frame (Fig. 1 (A)),
A new name forming the character string data to be inserted into the character frame is read (S3), and a candidate group of character string data is created (S4). That is, as shown in FIG. 1 (C), first,
The aspect ratio of the character is determined (S41), and the format of the character string is determined (S42). In this embodiment, regarding the aspect ratio of the character,
The concept is shown in FIG. 3 (A), where the vertical a and horizontal b of the character are 1:
It is set to one of the ratios of 1,10: 9,10: 8,9: 10,8: 10, etc., and the format of the character string is shown in Fig. 3 (B). For each horizontal and horizontal writing 1,2
Or centering 3, 4 or pattern 2 or 5 minutes down by 2 minutes.

Next, based on the delimiter in the name that becomes the character string data,
A candidate group of character string data is created (S43). In other words, if the name is "Tokyo Electric Power System Research Institute, Information Laboratory," a plurality of candidates 10 to 13 are created using the line break as a reference, as shown in FIG. 3 (C). It should be noted that what is shown in the figure is a group of candidates when the character string format is horizontal writing and line-alignment.

After creating the character string data candidates (FIG. 1 (A)), the character size is determined (S5). That is, as shown in FIG. 1 (D), first, the direction α is obtained for the candidate (S51). This direction α is an angle formed by the longitudinal center line and the diagonal line in the candidate as shown in FIG. 3 (C). Next, as shown in FIG. 4, it is determined in S25 described above. Direction from the center point C of the character frame α
Draw lines C1 and C2 (S52). And those lines C1, C2
And intersections B1 to B4 of the house frame data F are obtained (S53). Here, the positions of the intersections B1 to B4 are checked, and the latest intersection B1 is found at the vertex of the largest character frame G that fits within the house frame data F, that is, the center point C (S54). Next, the character size is appropriately determined based on the distance between the vertex (intersection point B1) and the center point C (S55).

This character size determination (S5) is performed for each of the candidates created in S4 (S5, S6), and if the character size is determined for all candidates (YES), the house frame data F
The optimum character string data for is selected from among all the candidates (S7). The selection of the character string data is performed by checking the compatibility with various selection criteria such as whether the character size is within a predetermined range.

That is, according to such a method, the character size is appropriately determined according to the size of the house frame data F, and the entire character string data is optimally matched with the house frame data F. Then, in this embodiment, this method is so-called soft programming, so that the insertion of the character string data is automated. As a result, it is possible to simplify the conventionally troublesome and troublesome instruction operation for inserting character string data, and improve convenience.

By the way, in the method described above, the character frame may become too small depending on the shape of the house frame data. For example, in the house frame data F1 shown in FIG. 5 (A), the character frame shown in FIG. Since the column data is inserted into the character frame G1, the character size may become too small with respect to the size of the house frame data F1. Therefore, in this embodiment,
Correction has been made.Specifically, the character frame for the vertical line b1
When the height n of G1 does not reach the predetermined standard, the above S2
The third and subsequent steps are performed for the quadrants D1 and D2 in addition to the midpoint A1 of the longest side a1 to set a plurality of character frame candidates, and the optimum character string G2 is selected from these candidates.

Now, FIGS. 6A to 6D are flowcharts schematically showing another embodiment of the present invention. And FIG. 7 is a conceptual diagram explaining the flowchart of FIG.

In this embodiment, similarly to the above-described embodiments, a candidate group of character string data is created (T1 to T6), but here, in those candidate groups, the aspect ratio of characters is not yet determined.

Next, all the vertices P that are not the longest side a1 are listed (T7, T8), and the candidates for the character frame are calculated (T7, T8).
9). That is, for the vertex P, the center line b2 and the center point C
(T91 to T95).

Then, with respect to the candidate of the character frame, the aspect ratio and the character size of the character are determined (T10). That is, the character string data candidates are applied to the character frame candidates, and the character aspect ratio and the character size at the time of matching are calculated (T101).
~ T105).

Here, the fitting of the character string data candidates for the character box candidate is repeated (T10, T11), and when all candidates are completed (T11, YES), the optimum character string data for the character box candidate is selected. And make a combination of both (T1
2). Then, for each candidate of the character frame, the optimum combination of the character string data candidates for the character frame candidate is repeatedly created (T9 to T13), and when all the character frame candidates are completed (T13, YES), the house frame Select the best character frame for the data (T14).

That is, also in the case of this embodiment, the character frame, that is, the character size is appropriately determined according to the size of the house frame data, and the entire character string data is optimally matched in the house frame data, as in the above-described embodiment. Therefore, the same effect can be obtained.

<< Effects of the Invention >> As described above in detail in the embodiments, according to the method for inserting character string data according to the present invention, the notation method for character string data based on the size of the surrounding frame and the arrangement direction ( The character size is appropriately determined according to the size of the character frame set therein (vertical writing / horizontal writing), and the entire character string data is optimally matched within the character frame, that is, the surrounding frame.

Therefore, by inserting a soft program into this method, the insertion of the character string data is automated. That is,
This can be preferably applied to automation of character string data insertion, which can simplify the instruction operation and improve convenience.
