Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a method for inserting character string data into irregularly shaped frame data on the coordinates of graphic data handled by a computer, etc. .

[Prior Art] Conventionally, computers and the like have handled figures such as maps by converting them into numerical data, that is, converting them into numerical data by fitting the figure to a predetermined reference point.
It is handled as graphic data on such coordinates.

For example, at electric power companies, etc., electricity is transmitted and distributed to each household based on a contract, so in order to understand and manage it,
The power distribution situation is mapped on a computer. In other words, Figure 23.

on a computer. This is a perspective view showing an example of such a graphic display.As shown in the figure, graphic data is created on a computer from map information such as an aerial photograph, leaving only the outlines of room frames, etc. Insert string data such as contract holder into
This is a so-called power distribution map, and the character string data is updated as appropriate and used for customer service.

[Problem to be solved by the invention] However, in the past, insertion of character string data (
update), in order to optimally match the character string data within the room frame, the computer operator inspects the specifications such as the coordinate position, size, and shape of the house frame in the displayed image J2, and updates the data as appropriate. Correspondingly, specifications such as the coordinate position and size of the character string data must be specified one by one, which poses a problem in that the instruction operation is cumbersome and time-consuming.

This invention has been made to solve the above-mentioned problems, and provides a character string insertion method that can be preferably applied to automation of character string data insertion to simplify instruction operations and improve convenience. Its purpose is to

[Means for Solving the Problems] In order to achieve the above object, the character string insertion method according to claim 1 of the present invention determines the widest part within the surrounding frame and calculates the center point of the widest part within the surrounding frame. a coordinate conversion process that sets new coordinate axes parallel and perpendicular to the straight line that passes through this center point and has the longest distance between the intersections with the surrounding frame;
Find the smallest rectangle that is circumscribed to the enclosing frame and whose sides are parallel to each new coordinate axis, and delete the part that overlaps less with the enclosing frame among the predetermined width parts that touch each side of this circumscribed rectangle, By repeating this until each side is included in the surrounding frame, the character frame creation process generates a character frame for drawing a character string, and the character string drawing direction is set vertically if the character frame is vertical. , a drawing direction determination process that sets the drawing direction horizontally when the text is horizontally long, a character string creation process that creates an optimal arrangement of character strings based on the divisibility information included in the character string data and the aspect ratio of the character frame, and the created A character size determination process that determines the character size so that the character string fits into the character frame above, and a character size determination process that divides the character frame equally to the number of lines of the character string created above, and places the character at the center of each line in the center of each divided part. This includes a drawing process for drawing the image so that it appears.

Further, the character string insertion method according to claim 2 of the present invention is a vector rewriting process that rewrites the direction of the vector constituting the surrounding frame data in a predetermined direction instead of the process of determining the inner width of the surrounding frame according to claim 1. , a dent removal process that examines the unevenness of the surrounding frame and removes the dents by examining the relationship between each rewritten vector, and a dent removal process that stops when a predetermined condition is met and removes the remaining portion. This includes a process for determining a temporary surrounding frame to be used as a temporary surrounding frame.

[Function] In the system according to claim 1 or 2 of the present invention, the font size is appropriately determined according to the size of the surrounding frame, and the drawing direction is determined to be an optimal direction according to the shape of the surrounding frame. , the string data is inserted into the box. Therefore, by converting this method into a software program, the insertion of character string data can be automated.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a flowchart showing a first embodiment of the invention. Here, before going into the description of the embodiment, the premise will be explained.

As shown in Figure 2, the drawing data includes the location of the house,
There is house map data (frame data) indicating the shape and house name data (character string data) indicating the corresponding house name, and an appropriate drawing is created based on them. The above-mentioned house map data is recorded data of vectors forming the shape of each house as shown in FIG. 3 fal, and in the example of FIG. In addition, the house name data is record data of the house name corresponding to the house in the house map data, as shown in Fig. ). Furthermore, this application aims to make it possible to easily confirm the correspondence between house plan data and house name data on a single drawing, and has set the following specifications (see FIG. 4).

Specifications: - Draw the characters of the family name data in any direction (see Figure 4).
a), (bl).

- Make sure that the characters of the house name data do not protrude from the house diagram of the house diagram data as much as possible (Figure 4 (C)).

- Family name data that can be divided into multiple lines can be plotted in multiple lines (Figure 4 (d)).

(e)).

In order to satisfy the above specifications, in this embodiment, the widest space in the base frame is found, and a character frame is set in the vicinity of that space for drawing. Note that the Y' axis is vertical and the X' axis is horizontal.
It is assumed that the Y' axis increases in the upward direction and the X axis increases in the right direction.

Now, the first embodiment will be explained using the flowchart shown in FIG.

a. Determining the size within the room frame (Step Sl) Find the smallest rectangle that circumscribes the room frame and is parallel to the X' and Y' axes. The rectangle is divided into straight lines parallel to the X' axis, Y axis, and j axis.
Divide into 2g portions. f.

The value of g can be any positive integer, but the larger the value, the better.

Among the intersection points of f-1 and g-i straight lines parallel to the X'' axis and Y' axis, select a point that satisfies the following condition.

conditions: ・It is a point inside the room frame.

・If you create the largest circle that does not touch the vectors that make up the base frame with this point as its center, its radius will not be shorter than the radius of a similar circle centered on any other point.

Let the selected point be C6 (see Figure 5).

b. Coordinate transformation (step S2) The following process is performed for C8 selected above.

First, vectors V1yV21...gV constituting the room frame
For n, draw a straight line parallel to any vI and passing through the bracket C8. There are multiple intersections between the straight line and the vector, and let d be the distance between the intersection closest to Co and the intersection closest to Co in the opposite direction. Find Vi for which this d is the largest (see Figure 6).

Next, find the angle between ■ and the X' axis. Assume that the angle made by ■1 with respect to the X' axis is θ (rad) in the counterclockwise direction.

When 1π/4≦θ≦π/4, the dual axis of X″-Y′ is θ(
The coordinate axes x-y are set by rotating them counterclockwise by rad) (FIG. 7(a)).

Similarly, when π/4〈θ〈3π/4, set the coordinate axis X-Y by rotating the -x'Y' twin axis counterclockwise by O-π/2 (rad) (see Fig. (bl).

When 3π/4≦θ≦5π/4, set the coordinate axis X-Y by rotating the x'-y' dual axis counterclockwise by O-π (rad) (Figure 7 (C)) .

When 5π/4 x θ〈7π/4, set the dual axis of X'-Y' to 0
Set the coordinate axis X-Y rotated counterclockwise by -3π/2 (rad) (FIG. 7(d)).

Creation of C1 character frame (step S3) This is the process of creating a character frame for drawing a character string, which consists of the following processes.

■Region creation (see Figure 8) Find the smallest rectangle that circumscribes the room frame of the house plan data and has each side parallel to the Y axis. This circumscribed rectangle is divided into f equal parts by a straight line parallel to the Y axis, and divided into g equal parts by a straight line parallel to the Y axis. As a result, the circumscribed rectangle is divided into fXg rectangles,
This rectangle will be called a region. The values of f and g are arbitrary integers, but are set to be sufficiently large. Let B1 be a rectangle surrounding the area.

■Region deletion (see Figure 9) Consider a row of regions that touch the four sides of a certain circumscribed rectangle B. Regarding the arrangement of each area, the number of areas that completely fit within the room frame of the house plan data is set as m8, and the number of areas that do not fit completely is set as mo.

m. / (m 0 + m l) is calculated, and the sequence of regions with the largest value is deleted. m, / (mo +
If there are multiple sequences with the largest value of mi), the sequence containing the least number of areas is deleted. m.

/ If there are multiple sequences with the largest value of (m0+m+) and there are multiple sequences with the smallest number of areas included in the sequence, one sequence is selected at random from among them and deleted.

■ Determining the character frame (see Figure 10) Repeat the deletion of the region (■) described above several times, and stop the process (■) when the first condition is satisfied.

A rectangle B determined by the remaining area is used as a character frame.

At this time, the coordinates of the lower left vertex of the character frame are (XM I N
, YM I N), and the coordinates of the top right vertex are (XMA
X, YMAX).

Conditions: - All areas touching the four sides of B4 are included within the room frame of the house plan data.

This allows setting a character frame that overlaps the shape of the room frame.

d0 Determination of Drawing Direction (Step S4) Next, the direction in which the character string is drawn is determined. Here, the character frame created above (X, MAX-X, MIN
) and (YMAX-YMIN), (XMAX
-XMIN) is larger (horizontal), see Figure 11 ta
When (YMAX-YMIN) is larger (vertical), the family name data is written vertically as shown in FIG. 11 (bi).

Creation of e0 character string (step S5) This process sets the format of the character string, which is how the character strings are arranged and drawn, and consists of the following processes.

■ Setting the board format (see Figures 1-2) Assume that the aspect ratio of each character is 1:1, and that the size of each character can be changed freely. At this time, consider that the divisible information 'tree' is also one character, and consider that the character string data can be divided into arbitrary parts between arbitrary characters, and arrange the characters in the character frame so that there are as few blank spaces as possible. think of. The total number of characters including divisible information is M, the number of characters in one line is k, and the number of characters in one column is! 1 When the drawing direction is vertical (YMA
XYMIN): (XMAX-XMIN) = P: (1, When the drawing direction is horizontal (XMAX-XMIN): (YM
If we set AX-YMIN)=p:q, we get k-12:M p:q=:ff, so we get. Here, K is the smallest integer greater than or equal to k, and L is the smallest integer greater than or equal to p.

As a result, when a character string is arbitrarily divided and arranged in five rows and columns, an integer number K can be obtained that will result in a character string similar to the character frame.

(2) Correcting the number of lines Check the value of (XMAX-XMIN) when the drawing direction is vertical, and (YMAX-YMIN) when it is horizontal, and set this value as J. Furthermore, the minimum character size that can be drawn is defined as width W and height h. If the drawing direction is vertical and the minimum width (wXL) of the character string data obtained using the board format is greater than J, or when the drawing direction is horizontal and the minimum height of the character string data obtained using the board format If (hXL)>J, L lines of character strings cannot be drawn in one character frame. Therefore, only in this case, when the drawing direction is vertical, L is the maximum integer value that satisfies wXL<J, and when the drawing direction is horizontal, L is the maximum integer value that satisfies )IXL<J. In addition, if the value of L changes regardless of the vertical or horizontal direction of drawing, it shall be the minimum integer value that is greater than or equal to M/L. However, when the drawing direction is vertical and J < w, the width of the character frame is set to W and L=1. In other words, XMA
Add (J-w)/2 to the value of X, and from the value of XMIN (J
−w)/2. Similarly, when the first drawing direction is horizontal and J<h, the height of the character frame is set to h and L=1. In other words,
Add (J-h)/2 to the value of YMAX, and subtract (J-h)/2 from the value of YMIN.

■Determining the format (see Figure 13) As shown in Figure 13 (al), separate one character string data each time divisible information appears, and number it from the beginning as character string 19 character string 2... Add m to the number of characters in string i
(i).

When L≠1, the character string included in row i where i < L is determined as follows.

Assume that the character string S is at the beginning of the remaining character strings excluding the character strings included in the lines up to the ii-th line. If i=1, then s=1. As shown in Figure 13('b), m(s)+m(s+1)+m(s+2)+-"l
Find the largest integer t such that l(t)+(t-1)<K. Note that K is a guideline for one line of character strings determined in the board format.

t (s) + m (s + 1) ten ... ten, ll
) +(t, -5) )+ to -(m(s)+m(s+1
)+ -+m(t+1)+(t+l-5))<0, the total number of characters from string S to string t is greater than the total number of characters from string S to string t+1. It is determined that the character string is closer to K than the value of the combined number of characters, and the character string included in the i-th line is set as the character string S to character string t and all of the divisible information contained between them. In other cases, the character string included in the j-th line is the character string S to character string t+1 and all of the divisible information contained between them. That is, as shown in FIG. 13, the character string from one character string S to the part before the divisible information closest to the character is the character string to be drawn in that line.

In the illustrated example, the character string starts from the character string S. Also,
When m (s)≧, the character string in the i-th row is set as the character string S.

When 1==L, the character string included in the i-th line is
It is assumed that all the remaining character strings excluding the character strings included in the line up to the i-th line and all the divisible information included in that part are included. When L"=1, the i-th row contains all the character string data. Either the 61st row to the L-th row is determined using the method described above, or all the characters are determined in the j-th row in the middle. If column data is included, finish formatting.If all character string data is included in the i-th row indicated by a value i that is less than L, change the value of L to a new i shall be.

As a result, the range of character strings included in each line to be plotted from the i-th line to the L-th line is determined.

Determination of f0 character size (step S6) The character size is determined. Let m (MAX) be the number of characters in the line with the largest number of characters among the character strings in all lines. At this time, the character size of one character is determined as width W and height H as follows (first
(See Figure 4 (at, ()))).

When the drawing direction is horizontal W: (XMAX-XMIN)/m(MAX) X aH
= (YMAX-YMIN) Le × β When the drawing direction is vertical, W = (XMAX-XMIN)/L x 13t (=
(YMAX-YMIN)/m(MAX) However, in the case of both vertical and horizontal directions, the values of H and W are the preset maximum character size HMAX.

If larger than WM, AX, H=HMAX, W=WM
Let it be AX. Further, α and β can be arbitrarily set as real numbers greater than 0 and less than or equal to 1. If the values of α and β are close to 1, the characters will be drawn large within the character frame, and if the values are close to 0, the characters will be drawn small. Furthermore, the line spacing during plotting is determined by β.

For the width W and height h of the smallest character that can be drawn, suppose W
If <w, the value of W is set to W.

Similarly, if H<h, the value of H is set to h.

This provides a font size that allows drawing.

g9 Plotting (Step S5) This is the process of actually plotting, which consists of the following processes (15th
(see figure).

■Dividing the character frame Divide the character frame into parts equal to the number of lines in the character string. In the case of vertical writing, the character frame is divided into L parts by a straight line parallel to the Y axis, and from the right part, frame 1, frame 2, etc. ..., as a frame. In the case of horizontal writing, the character frame is divided into L parts by a straight line parallel to the X axis, and the character frame is divided into L parts in order from the upper part. Frame 2.・・・
・As a frame.

(2) The first line of the character string data corresponds to the drawing frame 1, the frame 2 and the frame 3 similarly correspond to the second and third lines, and the frame corresponds to the Lth line. Basically, the character string in the i-th line is drawn using the frame i as a guide. This method will be described below.

When the number of characters in the i-th string is m (i), m
(i)/Let the second character be me. However, m (i)
When is an odd number, the 72nd character (m (i) + 1) is set to mc. Draw two diagonal lines from the four vertices of frame i, set their intersection as Po, and the center of letter mc is P. Draw the character string of the i-th line on the frame i so that it appears in the frame i. When the drawing direction is vertical, the character string is drawn from top to bottom parallel to the Y axis, and when the drawing direction is horizontal, the character string is drawn parallel to the X axis from left to right. The orientation of each character is such that the top of the character faces toward the Y-axis. Also, increase the distance from the edge of the - character to the edge of the adjacent character by a set value. Or the distance between the centers of one character in the vertical direction (YMAX-YMIN)/m (MAX
), in the horizontal direction (XMAX-XMIN)/m (MA
Open only X).

This allows character string data to be drawn at arbitrary character intervals at the center of the character frame.

The drawing results of this example drawn as described above are shown in the first
It is shown in Figure 6(a), et al.

As described above, in this embodiment, the character size is appropriately determined according to the size of the house frame, and the drawing direction of the character string is determined in the optimal direction according to the shape of the house frame. String data is inserted into. In this embodiment, the above-described method is converted into a software program and operates on a computer, so that the insertion of character string data is automated.

FIG. 17 is a flowchart showing a second embodiment of the invention. In this example, in order to satisfy the specifications mentioned above,
Examine the irregularities around the room frame, remove the irregularities as much as possible, and set the character frame in the remaining area. As in the first embodiment, the vertical axis is the Y' axis and the horizontal axis is the X' axis, with the Y' axis increasing upward and the X1 axis increasing rightward.

The second embodiment will be described below using the flowchart shown in FIG.

a. Rewriting the vector (step 11) Rewriting the vector of the house map data. As shown in FIG. 18, the direction of the vector of the house plan data is not constant, so this is rewritten to change the direction of the vector counterclockwise.

b. Removal of dents Here, the following processing is performed.

■ Examine the unevenness (see Figure 19) The vertex of the house frame is the end point of one vector and the start point of another vector. Find the angle between the vector that touches at the starting point and the vector that touches at the end point at a certain vertex.

Consider a straight line that is an extension of a vector that touches a certain vertex at its end point, and let the direction from the start point to the end point of that vector be ``+''. At this time, if the vector that touches the vertex at the starting point is on the right side when the straight line is viewed from the negative to the positive direction, it is considered to be a concave, and otherwise it is considered to be convex and flat.

■Remove the dent The vertex determined to be a dent in ■ is P,, P2゜...
Let it be Pk. The vector that touches P at the end point is Ve
As i, the vector that touches Pi at the starting point is VS
Let it be i.

PI*P2y..., perform the following calculation for all Pk.

When a line extending from the starting point of Vei toward the ending point is drawn from Pi, the point closest to P among the points where the line intersects with the vector forming the room frame is set as Pei. The chamber frame is divided into two parts by the straight line Pei P't,
Let the area of the smaller part of the two divided house frames be Sl.

Similarly, when a line extending from the end point of V5i toward the starting point is drawn from P, the point closest to P is defined as Ps, among the points where the line intersects with the vector forming the room frame. The room frame is divided into two parts by the straight line Ps□P, but if the area of the smaller part of the two divided house frames is smaller than the previously calculated Si, this area is calculated as SI.
shall be.

■Deleting convex portions (see Fig. 20) When SlyS2y..., Sk are found, it is assumed that the smallest one among them is S. If there are multiple minimums, choose one arbitrarily. At this time, consider the vector that constitutes the area S1, and if it includes the straight line PelPt, add V'71 to the vector indicating the room frame, and the area S,
Remove part of the frame that makes up the house. If the vectors constituting Si include the straight lines Ps, P, then add r J to the vector indicating the room frame and remove part of the house frame constituting the area S.

C3 Determination of temporary house frame (step 513) Repeat the above "b. Removal of dents" to remove the white part and eliminate the dents, but if you repeat step ①, the area will be drastically reduced, and the remaining part will be removed. If you set a text frame to , the text becomes smaller.

Therefore, the above-mentioned "b. Removal of dents" requires stopping conditions, which are described below.

Conditions: When the area of the room frame is less than 1/SL of the initial area. However, SL is an arbitrary real number, and a value of about 2≦SL≦3 can be considered.

・When the point that is a dent has completely disappeared When the above conditions are met, stop the above-mentioned "b. Removal of dents",
The remaining chamber frame at this time is considered a new chamber frame (Fig. 21 (al, (bl)).

d. Coordinate transformation (step 514) The longest vector of the house frames found in "c. Determination of temporary room frame" above is set as vi.

The subsequent steps are the same as those described in "RB and coordinate transformation" in the first embodiment. That is, find the angle between ■ and the X' axis. X
The angle made by V with respect to the 'axis in the counterclockwise direction is θ (rad)
Suppose that

-π/4≦θ≦π/4, the dual axis of x'-y' is θ(
The coordinate axes x-y are set by rotating them counterclockwise by rad) (FIG. 7(a)).

Similarly, when π/4〈θ〈3π/4, set the coordinate axis X-Y by rotating the dual axis of X'Y' counterclockwise by θ-π/2 (rad) (Fig. of)).

When 3π/4≦θ≦5π/4, the dual axis of X'-Y' is θ
