CONSTITUTION:The device decides the size of a character width per one character of a valid output character string from the number of valid output characters in the index output character and a distance between coordinates of leader lines, which are extracted from a data base (DB) 4, with a character width size deciding part 24 and when the size meets a prescribed evaluation reference, the device makes the height of each character equal to the value of the character width size to array it in a character string editing area. A coordinate string data editing part 35 makes a character string output area into a frame graphic and when another frame graphic overlaps this frame graphic, the part 35 moves the overlapping frame graphic in the direction of avoiding overlapping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an index character string output device for a two-dimensional graphic, and more particularly, to edit the size of the index character string on the flag-raising line drawn from the two-dimensional graphic or to edit the index character string. The present invention relates to a technique for rearranging regions to be arranged.

[0002]

2. Description of the Related Art Conventionally, there is a graphic attribute data management system (mapping system) based on a two-dimensional graphic such as a road map, architectural design drawing, or ruin distribution drawing.
In this type of mapping system, when a drawing is congested or when it is desired to specify a figure, a leader line is raised from the figure and attribute data corresponding to the figure in a one-to-one manner, that is, management item value, management data. , The data type, its output format, etc. are automatically selected and extracted from the attribute database to generate the index character string (including numbers and symbols),
This is arranged in a predetermined area on the lead line and displayed or printed together with the drawing. This process is generally called flag raising process and is embodied as an index character string output device.

FIG. 11 is a procedure diagram of flag raising processing in a conventional index character string output device. First, coordinates of three points designated by an operator, that is, leader lines (flag raising line segment strings).
The starting point coordinates P1, the inflection point coordinates P2, which is the head area of the index character string, and the end point coordinates P3 are acquired (S301). Next, the attribute data of the figure designated by the coordinate P1 is acquired (S30
2) A specific target item value is acquired from this attribute data (S303). The target item value is specified based on the separately defined flag raising style information.

Next, the target item value is converted into a character string (S30).
4). For example, in the alphanumeric / kanji character type, spaces up to two or more consecutive digits are converted into a character string. For the real number / integer type, the number of significant digits is converted to a character string. Font size (width,
The height uses a layer default value (system-defined data) that generates a character string. Next, a flag raising line segment (leading line) is generated from the coordinates P1-P2-P3 (S30).
5). At this time, the coordinate P3 is automatically expanded / contracted to the final character position of the generated character string, and the length of the line segment string of the coordinates P2-P3 is adjusted. After that, the index character string is arranged in the character string editing area where the coordinate P2 is the character string display start point and the coordinate P3 is the character string generation direction point (S306).

By such a processing, the index character string of the figure to be specified is automatically displayed or printed on the drawing line segment sequence on the drawing, so that the drawing can be easily seen according to the purpose, and each figure can be specified at a glance. Can be obtained. In addition, the above flag raising process can also be performed online.
In addition, recently, management of attribute data of a drawing in which a plurality of layers are overlapped is also performed.

[0006]

As described above, in the conventional index character string output device, flag raising style information, such as the number of characters to be managed, the size of the index character string, or the information indicating the array area thereof, is not provided. , Is fixedly defined in advance, and automatic processing is performed by an operator's instruction in accordance with the contents of the definition. This automatic processing works effectively in the case of a relatively simple drawing, but in a drawing in which a figure to be specified is congested, a problem due to the automatic processing has been revealed.

For example, when the number of characters to be managed is redundant,
As the scale of the drawing becomes smaller and the figures become congested, the index character strings become more difficult to see and the chances of overlapping increase. This is particularly noticeable in the case of a drawing in which a plurality of layers are superposed, and as shown in FIG. 9, the index character strings overlap each other, which causes the drawing to be difficult to see. In view of such a problem, the present invention can adjust the size or the output area of the index character string of the two-dimensional figure included in the drawing according to the congestion status of the drawing, and also considers other index character strings. It is an object of the present invention to provide an index character string output device that enables the above editing.

[0008]

An index character string output device according to the first aspect of the present invention which achieves the above object, is an attribute database for storing attribute data corresponding to each one-to-one correspondence with a plurality of two-dimensional figures, and a specific attribute database. A line segment sequence generation unit that determines a first coordinate point that indicates a two-dimensional figure and second and third coordinate points that form a character string editing area, and generates a line segment sequence that connects each coordinate point; An attribute data search unit that selectively extracts an index character string of a two-dimensional figure from the attribute database, and a character string editing unit that arranges the extracted index character string in the character string editing area. In this configuration, the character string editing unit detects the number of effective output characters from the extracted index character string, the second and third inter-coordinate distance, and based on the detected distance value, Character width size determining means for determining the character width size per valid output character, and an index for arranging the valid output character string in the character string editing area when the determined character width size satisfies a predetermined evaluation criterion. And character arrangement means.

The index character arranging means preferably arranges the characters in the height direction of each character to be arranged in the character string editing area so that the size of the character is the same as the character width size.

Further, the index character string output device according to the second aspect of the present invention which achieves the above object, has a one-to-one correspondence with a plurality of two-dimensional figures.
An attribute database that stores the attribute data corresponding to
In an apparatus including an attribute data search unit that selectively extracts an index character string of a two-dimensional figure from the attribute database, and a character string editing unit that arranges the extracted index character string in a character string editing area formed at a predetermined position A frame graphic forming means for converting the character string edit area in which the index character string is to be arranged into a frame graphic, and coordinate string data storage means for storing coordinate string data of each frame graphic in association with the index character string. A frame figure retrieving means for specifying a reference frame figure based on the data stored in the coordinate sequence data storage means and for detecting all other frame figures in a position overlapping with the reference frame figure, and the detected other frame figure To move in a direction to avoid overlapping with the reference frame graphic, and a coordinate string data updating means for updating the stored data of the coordinate string data storing means with the coordinate string data of the moved frame graphic. Characterized by providing a data updating means.

More specifically, the frame figure moving means is
The other frame figure is moved stepwise within a predetermined allowable range.

[0012]

In the index character string output device of the first aspect of the invention, the character number detecting means detects the effective output character string from the index character string selected and extracted from the attribute database. Here, the effective output character string means, for example, an actual output target character string excluding spaces and unnecessary characters in a predetermined data format. The character width size determining means determines the character width size per character of the effective output character string based on the second and third inter-coordinate distances representing the character string editing area on the line segment string. Then, when the character width size satisfies a predetermined evaluation criterion, these valid output character strings are arranged in the character string edit area. In addition,
In the configuration in which the size of each character to be arranged in the character string editing area in the height direction is arranged to be the same value as the character width size, the character size can be arbitrarily adjusted according to the inter-coordinate distance.

In the second index character string output device, first, the character string edit area in which the index character string is to be arranged is framed,
The coordinate string data of each frame graphic is stored in association with the index character string. After that, the reference frame graphic is specified, and all the other frame graphics existing at positions overlapping the reference frame graphic are detected by the frame graphic search means. Then, within the predetermined allowable range, the other frame graphic is gradually moved in a direction in which it does not overlap the reference frame graphic, and the coordinate string data storage means is updated with the moved coordinate string data. This prevents overlapping of the index character string edit areas.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of an essential part of an index character string output device according to an embodiment of the present invention, in which 1 is a terminal device for inputting / outputting coordinate data and attribute data and displaying the same, and 2 is an editing of an index character string. A character string editing device 3 for editing the character string output position editing device for editing the output area of the index character string, and 4 an attribute database (hereinafter referred to as an attribute database for storing attribute data for each drawing or each figure forming each drawing). , DB) 5 is an intermediate file for image output, and 6 is an output device such as a display device or an electrostatic plotter. It should be noted that FIG. 1 shows the configuration of only the part for carrying out the present invention.

The character string editing apparatus 2 of this embodiment includes an input / output (I / O) control unit 21, a coordinate data input unit 22, an attribute data search unit 23, a character width size determination unit 24, and a line segment sequence generation unit 25. , An index character array unit 26, and a DB interface 27.

The coordinate data input unit 22 inputs into the apparatus three-point coordinates sent from the terminal device 1, that is, the starting point coordinates, the inflection point coordinates, and the ending point coordinates of a line segment sequence described later. The attribute data search unit 23 selects and extracts from the DB 4 the index character string of the two-dimensional figure designated by the starting point coordinates. The character width size determination unit 24 detects the number of valid output characters from the extracted index character string and determines the character width size of each valid output character based on the coordinate distance between the inflection point coordinates and the end point coordinates. To do. This will be described later. The line segment sequence generation unit 25 is a known graphic creation software that generates a leader line based on the above three-point coordinates. The index character arranging unit 26 arranges the size of each character in the height direction to the same value as the character width size when the character width size reaches the evaluation standard, and arranges it in the character string editing area. This character string data is also stored in the graphic table 41 described later.

Further, the character string output position editing apparatus 3 of the present embodiment has an input / output (I / O) control unit 31, an attribute data search unit 32, a frame graphic generation / storage unit 33, a frame graphic inspection unit 34, and coordinates. Column data editing unit 35, coordinate column data update / output unit 3
6 and the DB interface 37.

The attribute data retrieving unit 32 selects and extracts an index character string of a graphic to be specified from the DB 4 as command data from the terminal device 1 or as post-processing of the character string editing device 2. The frame graphic generation / storage unit 33 generates a character string edit frame graphic by graphicizing the character string edit area in which the index character string is arranged, and also generates coordinate string data (position data of the character string edit area) of each frame graphic. ) Is stored in the character string data table 43 described later in association with the index character string. The frame graphic inspection unit 34 specifies one reference frame graphic from the character string edit frame graphic, detects all other character string edit frame graphics existing at positions overlapping with the reference frame graphic, and determines the degree of overlap and It is inspected whether or not each detected frame figure can be moved. The coordinate string data editing unit 35 moves the other character string editing frame graphic stepwise in a direction to avoid overlapping with the reference frame graphic when the inspection result indicates that the character string edit frame graphic can be moved. The coordinate string data update / output unit 36 updates the contents of the character string data table 43 with the coordinate string data of each moved character string editing frame graphic, and temporarily stores it in the output intermediate file 5 together with the index character string. .

Further, the DB 4 includes at least a graphic table 41, a layer definition table 42, and a character string data table 43, and these tables manage attribute data for each graphic. As shown in FIG. 2, the DB 4 has a plurality of layer structures A to N, and performs a process relating to graphic attribute data using the mesh area 40 of each layer as a unit work area. FIG. 3 shows the above tables 41 to 43.
FIG. 4 is a diagram illustrating an example of the contents of FIG. 1 and its relationship, and the graphic table 41 stores graphic numbers # 1 to #N and line segment coordinates and character string information for each graphic for each layer.
Defines character font data, character font width ratio, character font height, and other primitive information. The character string data table 43 is a table that corresponds to each figure number on a one-to-one basis, and stores the coordinate string data of the above-mentioned character string editing frame figure, a processing flag indicating an editing processing result, and the like. The setting contents of each of the tables 41 to 43 are arbitrary and do not necessarily have to be based on this example.

Next, the processing contents of the character string editing device 2 will be described with reference to FIGS. 1, 4 and 5. First, the editing device 1
The three-point coordinates input from, that is, the coordinates P1, P2, P3 of each point shown in FIG. 5A are acquired (S101). The attribute data search unit 23 searches the attribute data of the figure designated by the first coordinate P1 and specifies the target item value (S10).
2).

The character width size determination unit 24 acquires the number of effective character strings (n) from the specified target item value (S103), and the inter-coordinate distance (L) between the second and third coordinates P2-P3. Is calculated (S104), and the distance L is divided by the number of characters n to obtain a character width size a per character.
Is acquired (S105). FIG. 5B shows an outline of this processing. At this time, if the character width size a is 1 mm or less, a coordinate indication error message is sent to the terminal device 1 via the I / O control unit 21 (S107), and the process is terminated. On the other hand, when the character width size a exceeds 1 mm, the effective character string is made into a graphic with the character width size a (S108). At this time, by setting the size of the character in the height direction to be the same as the character width size a, each index character size can be arbitrarily changed according to the value of the three-point coordinate.

After that, as shown in FIG. 5C, the line segment sequence generation unit 25 generates a flag-raising line segment sequence graphic, that is, a lead line, based on the three-point coordinates (S109). The index character string arranging unit 26 arranges the index character string with the adjusted character width size and / or character height size in the character string edit area (broken line area in FIG. 5D) formed on the lead line. (S110) Further, the character string is stored in the graphic table 41, and the process ends.

FIG. 6 is a more specific process explanatory diagram of the character string editing device 2 in which the figure ID (identification number) is 102.
An example is shown in which the flag is raised from the target figure. From the three-point coordinates P1 to P3 input to the coordinate data input unit 21, the target figure having the above figure ID is first selected from the DB4, and the target item value is specified from the corresponding attribute data, which is the predetermined data type. It is guided to the character width size determination unit 24 in the defined format. The character width size determination unit 24 edits the target item value while providing one space between each item and ignoring the space in each item. In the illustrated example, the number of effective characters is 18, and it can be seen that the number of effective characters is significantly reduced as compared with before processing.

Next, the processing contents of the character string output position editing device 3 of this embodiment will be described with reference to FIGS. 1 and 7 to 10. FIG. 7 is an overall processing procedure diagram. First, the attribute data search unit 32 searches for all character strings in the processing space, and the figure number, figure reference point coordinates, three-point coordinates, and character string edit frame coordinate series. Is acquired, converted into a frame graphic, and stored in the corresponding area of the character string data table 43 (S201). The frame graphic inspection unit 34 determines whether or not the inspection is completed (S202), and if not completed, one record is acquired from the character string table 43, and this is set as a reference frame graphic (S203). At the same time, for example, all other frame figures within the parallel movement allowable range are acquired as comparison target frame figures (S205). Then, these overlaps are checked (S205), and when they overlap, the comparison target frame graphic is moved in a predetermined step (S206). It is determined whether or not the moving arrangement is completed (S207), and if it is not completed, the coordinate sequence data of the moved comparison target frame graphic is updated (S20).
8) Then, the overlapping of the frame figures at the destination is checked again (S209). If they overlap, the process returns to S205. When the frame figures do not overlap (S205, 209) and when the movement arrangement is completed (S207), the processing flag of the corresponding character string data table is updated to "rearrangement" (S210), and the processing ends.

The process of converting the character string editing area into a frame graphic will now be described. The type information such as the character height, the character interval, the character width ratio, the number of characters, etc. is acquired from the index character string corresponding to the figure number of the figure table 41 and the previously defined layer definition table 42. Then, the index character string length of the figure number is calculated from the acquired model information. Here, when the number of characters is n, the character height is h, the width ratio to the character height is w, and the character spacing is d, the index character string length T is obtained by the following equation.

[0026]

## EQU00001 ## Index character string length T = n. (H.w) + (n-1) .d

Next, an edit area for actually outputting character information is formed from the index character string length T and the type information. Specifically, starting from the inflection point coordinate P2 (X2, Y2), which is a predetermined distance from the starting point coordinate P1, the inflection point coordinates P3 to P5 (X3, Y3) surrounding the character string in a rectangular shape are used. , X4, Y4, X
5, Y5) is calculated. Each coordinate is calculated by, for example, a geometric method as in the following formula.

[0028]

[Formula 2] P3 (X3, Y3) = (X2 + L ・ COSθ, Y2 + L ・ SINθ) P4 (X4, Y4) = (X2 + L ・ COSθ / h ・ SINθ, Y2 + L ・ SINθ + h ・COSθ) P5 (X5, Y5) = (X2-h ・ SINθ, Y2 + h ・ COSθ)

In this way, the above processing is performed based on the character strings on all the graphic tables 41 to form a frame graphic, and the character string data table 43 is updated using the graphic numbers as keys.

FIG. 8 is a diagram showing an outline of the overlap check processing (S205, 209) between the frame figures, in which the character string direction of the reference frame figure 80 is the X axis and the center of gravity of the figure is the origin for comparison. It is determined in which quadrant the intersection with the figures 81 and 82 exists. Although the determination criterion in this case can be set arbitrarily, in the present embodiment, in the case of (b), the number of intersections of the comparison target frame graphic 81 is one, and for example, it is possible to move in the Y axis direction of the quadrant in which no intersection exists. It can be rearranged.
In the case of (d), although there are a plurality of comparison target frame graphics, the upper frame graphics can be rearranged because they can be moved in the quadrant direction in which there is no intersection. In the case of (c), the third or fourth
Since it can be moved in the Y-axis direction of the quadrant, it can be rearranged. In the case of (e), since the intersection points exist in all quadrants, relocation is impossible. In this case, a message to that effect is output.

FIG. 9 is an example of a drawing obtained by conventional flag raising processing, and FIG. 10 is a character string output position editing device 3 of this embodiment.
It is an example of a drawing obtained by. Conventionally, when a plurality of layers are overlapped, even if a plurality of index character strings exist in the vicinity, this cannot be detected, so that it is very difficult to see as shown in FIG. 9, but as in the present embodiment. By checking the overlapping of the frame figures before outputting the index character strings and automatically moving in the direction to avoid the overlapping, even in the drawing in which the figures to be specified are congested, the index character strings are easy to see as shown in FIG. Therefore, this kind of conventional problem can be solved.

[0032]

As is apparent from the above description, according to the first invention, the effective output character string 1 is determined based on the coordinates of the character string editing area on the line segment string drawn from the desired two-dimensional figure. The character width size per character is determined, and when this character width size meets the predetermined evaluation criteria, these valid output character strings are arranged in the character string edit area. It has the effect of making it easier to see.
Also, in the configuration in which the size of each character to be arranged in the character string editing area in the height direction is arranged to be the same value as the character width size, the character size can be arbitrarily adjusted according to the distance between coordinates. The effect is that a drawing can be easily created according to the application.

Further, according to the second invention, all the other character string edit frame figures existing at the positions overlapping with the one reference frame figure move in a direction to avoid the overlap before outputting the index character string. Even if the index character string edit area is congested, overlapping of characters is prevented, and there is an effect that a more legible drawing can be automatically created. Also, the movement is
Since the steps are performed stepwise within a predetermined allowable range, there is an effect that the figure can be surely associated with the figure to be specified.

As described above, according to the present invention, the size or the output area of the index character string of the two-dimensional figure included in the drawing can be adjusted according to the congestion state of the drawing, and another index character string can be adjusted. It is possible to provide an index character string output device that enables editing in consideration of the above.
