[0019]
Each data stored in the TD 11c can be updated at any time by inputting new data from the KB 2 and updated by data calculated by a flowchart described later.
Next, the operation described in the first embodiment will be described with reference to FIGS.
In the first embodiment, the process until the map is created and displayed is the same as that of a normal graphic processing apparatus, and the details thereof are omitted.
[0020]
For example, it is assumed that the user has drawn a map as shown in FIG. Reference numerals 21 and 25 denote roads, and the coordinates and road width of each are DWa at (Xa, Y0) and DWb at (Xb, Y0). Reference numerals 22 to 24 denote buildings, and their coordinates are (X1, Y0), (X2, Y0), and (X3, Y0). The building width is W1 to W3. Processing executed when the road 21 is moved to the right (X direction) as shown in FIG. 6B from such a state will be described with reference to the flowchart of FIG. Further, the road to be moved is designated from KB2.
It is assumed that the road or building drawing process or the drawing result executed in the flowchart of the present embodiment is displayed on the LCD 3.
[0021]
FIG. 7 is a flowchart showing the processing flow of the first embodiment.
First, in step S1, coordinates after movement of the road 21 are calculated. The calculated coordinates are stored as new coordinates in the road coordinates of the DD 11b. In the first embodiment, since the movement is only in the X direction, only the X coordinate is changed. If the movement distance is 1, then only 1 should be added to the X coordinate before the movement, so the coordinate after the movement is (Xa + 1, Y0), and the road coordinates of the road 21 are updated.
[0022]
In step S2, the division distance L between the road 21 and the road 25 before movement and the division distance L ′ between the road 21 and the road 25 after movement are calculated. In this case, L = Xb−Xa and L ′ = L−1. Then, each building in the partitioned area sandwiched between the road 21 and the road 25 is moved by an amount corresponding to the ratio L ′ / L of the two numerical values.
In step S3, a new X coordinate is calculated in order to move the buildings 22 to 24 in the right direction. A new X coordinate for movement is calculated using the ratio L ′ / L obtained in step S2. If the X coordinate before movement is Xn and the new X coordinate is Xn ′,
Xn ′ = Xb−L ′ (Xb−Xn) / L (n is a positive integer) (1)
Is used to calculate a new coordinate Xn ′. Here, the X coordinates X1 to X3 of the buildings 22 to 24 are respectively substituted into the mathematical formula (1) to calculate new X coordinates X1 ′ to X3 ′. The calculated new X coordinates X1 ′ to X3 ′ are stored and updated in the building coordinates of the TD11c of the corresponding building data.
[0023]
In step S4, the moved road 21 and the buildings 22 to 23 are moved according to the data stored in the updated DD 11b of the road 21 and the data stored in the TD 11c including the calculated new X coordinate of each building. Drawn. In addition, when buildings are too close to each other and overlap, they are displayed in an overlapping manner.
As described above, according to the first embodiment, when the road 21 is moved, the buildings 22 to 24 are moved according to the movement. Therefore, the building is moved in the area secured for moving the road 21. Therefore, complicated operations are reduced and work efficiency is improved.
[0024]
<Embodiment 2>
In the first embodiment, when moving buildings overlap each other when moving on a road, the buildings are displayed in an overlapping manner. In the second embodiment, after the building is reduced in accordance with the building width, the building is moved so that the building is not overlapped.
[0025]
Processing executed in the second embodiment will be described with reference to FIGS.
FIG. 9 is a flowchart showing the processing flow of the second embodiment.
In the second embodiment, it is assumed that the road 21 is moved to the right (X direction) by 1 as in the first embodiment. Accordingly, the processing of step S1 to step S3 in FIG. 5 corresponds to step S11 to step S13 of FIG. 9, and thus detailed description of the processing is omitted.
[0026]
In Step S1 4, a building width of each building after the movement of the road 21, it is calculated in accordance with the ratio L '/ L. If the width of each building after moving is Wn ′,
Wn ′ = Wn × L ′ / L (n is a positive integer) (2)
Is used to calculate a new building width Wn ′. Here, the building widths W1 to W3 of the buildings 22 to 24 are respectively substituted into the formula (2) to calculate new building widths W1 ′ to W3 ′. The calculated new building widths W1 ′ to W3 ′ are stored and updated in the building width of the TD11c of the corresponding building data.
[0027]
In step S15, the image data BM of the buildings 22 to 24 is reduced in accordance with the updated building widths W1 ′ to W3 ′, and the image data BM of the buildings 22 ′ to 24 ′ is generated as reduced buildings. Updated.
In step S16, the road 21 is reduced to the moved road 21 by the updated data stored in the DD 11b of the road 21 and the data stored in the TD 11c including the calculated new X coordinate and building width of each building. Buildings 22 ′ to 24 ′ are drawn (see FIG. 8).
[0028]
As described above, according to the second embodiment, in the first embodiment, when a building overlaps as shown in FIG. 6B, each building corresponds to each building width of the overlapping building. By reducing the size, it can be displayed so that the buildings do not overlap.
In the first embodiment and the second embodiment, the processing executed when the road 21 in FIG. 6A is moved to the right has been described, but conversely the case where the road 25 is moved to the left. The above-described processing can also be applied. The process executed in this case will be described with reference to the flowchart of FIG.
[0029]
If the movement amount of the road 25 is 1, the X coordinate Xb ′ of the new road 25 is calculated by Xb ′ = Xb−1 in step S21. This calculated value is stored and updated in the road coordinates of the DD 11b of the road 25. In step S22, a division distance L = Xb−Xa before movement and a division distance L ′ = L−1 after movement are calculated.
In step S23, a new X coordinate of the building is calculated. If the new X coordinate of the building is Xn ′,
Xn ′ = Xa + L ′ (Xn−Xa) / L (n is a positive integer) (3)
Is calculated using Further, the calculated new X coordinate of each building is stored and updated in the building coordinate of each TD 11c.
[0030]
Then, in step S24, the road 25 and the buildings 22 to 22 that have been moved by the data stored in the DD 11b of the updated road 25 and the data stored in the TD 11c including the calculated new X coordinate of each building. 23 is drawn.
The above-described processing can also be applied to a case where the road is widened such that the road 25 in FIG. The processing executed in this case will be described using the flowchart of FIG.
[0031]
That is, by moving on the road 25, a section with the road 21 is expanded. The division distance before movement and the division distance after movement are calculated respectively. It is only necessary to move each building in the section by an amount corresponding to the ratio of these two numerical values. Then, the actual coordinates are calculated as to how much the building should be shifted in the new, that is, widened area. For example, the X coordinate of the building 22 is X1, but how far it should be from the X coordinate Xa of the road 21 is calculated using a ratio to be calculated. This is performed for all three buildings, and each is redrawn according to the calculated road and the new coordinates of the building. In this case, the interval between buildings becomes wider.
[0032]
Hereinafter, a detailed flow will be described.
If the amount of rightward movement of the road 25 is 1, the X coordinate Xb ′ of the new road 25 is calculated as Xb ′ = Xb + 1 in step S31. This calculated value is stored and updated in the road coordinates of the DD 11b of the road 25. In step S32, a division distance L = Xb−Xa before movement and a division distance L ′ = L + 1 after movement are calculated.
[0033]
In step S33, a new X coordinate of the building is calculated. If the new X coordinate of the building is Xn ′,
Xn ′ = Xa + L ′ (Xn−Xa) / L (n is a positive integer) (4)
Is calculated using Further, the calculated new X coordinate of each building is stored and updated in the building coordinate of each TD 11c.
[0034]
Then, in step S34, the road 25 and the buildings 22 to 22 that have been moved according to the data stored in the DD 11b of the updated road 25 and the data stored in the TD 11c including the calculated new X coordinate of each building. 23 is drawn.
Furthermore, the above-described processing can be applied to a case where the road is moved not only in the left-right direction but also in the up-down direction. Processing in this case will be described with reference to the flowchart of FIG. 12 and FIG.
[0035]
For example, it is assumed that the user has drawn a map as shown in FIG. Reference numerals 26 and 30 denote roads, and the coordinates and road width of each are DWa at (X0, Ya) and DWb at (X0, Yb). Reference numerals 27 to 29 denote buildings, and their coordinates are (X0, Y1), (X0, Y2), and (X0, Y3). The building width is W1 to W3. Processing executed when the road 26 is moved downward (Y direction) from such a state as shown in FIG. 13B will be described with reference to the flowchart of FIG.
[0036]
First, in step S41, coordinates after movement of the road 26 are calculated. The calculated coordinates are stored as new coordinates in the road coordinates of the DD 11b. In this case, since the movement is only in the Y direction, only the Y coordinate is changed. If the movement distance is 1, it is sufficient to subtract 1 from the X coordinate of the coordinate before the movement, so the coordinate after the movement is (X0, Ya -1), and the road coordinates of the road 26 are updated.
[0037]
In step S42, the division distance L before movement and the division distance L ′ after movement are calculated. In this case, L = Ya−Yb and L ′ = L−1. Then, the buildings in the partitioned area sandwiched between the road 26 and the road 30 are moved by an amount corresponding to the ratio L ′ / L of the two numerical values.
In step S43, a new Y coordinate is calculated in order to move each building 27-30 downward. A new Y coordinate for movement is calculated using the ratio L ′ / L obtained in step S42. If the Y coordinate before movement is Yn and the new X coordinate is Yn ′,
Yn ′ = Yb−L ′ (Yn−Yb) / L (n is a positive integer) (5)
Is used to calculate a new coordinate Yn ′. Here, the Y coordinates Y1 to Y3 of the buildings 27 to 30 are respectively substituted into the equation (5) to calculate new Y coordinates Y1 ′ to Y3 ′. The calculated new Y coordinates Y1 ′ to Y3 ′ are stored and updated in the building coordinates of the TD11c of the corresponding building data.
[0038]
In step S44, the moved road 26 and the buildings 27 to 30 are moved according to the data stored in the updated DD 11b of the road 26 and the data stored in the TD 11c including the calculated new Y coordinate of each building. Drawn. In addition, when buildings are too close to each other and overlap, they are displayed in an overlapping manner.
In the above-described embodiment, the road is moved in either the left-right direction or the up-down direction, but it is of course possible to move in an oblique direction. In that case, it can be easily realized by performing a combination of the above-described processing by movement in the left-right direction and the processing by movement in the vertical direction. In addition, in FIG. 6B, the depiction of the overlapping state of the buildings is that the right building is behind, but conversely, the right building may be drawn in front.
[0039]
As explained above, when a map that has been completed once is further drawn with a more precise and accurate map by fine movement of the road, the movement process can be easily performed without worrying about the position of the building. .
In addition, the positional relationship between the road and the building does not change by controlling the movement of the road so that the space between the buildings widens or narrows according to the expansion or contraction of the section, or in some cases the buildings overlap. There is.
[0040]
Note that the present invention can be applied to a system composed of a plurality of devices (for example, a host computer, interface device, reader, printer, etc.), or a device composed of a single device (for example, a copier, a facsimile machine, etc.). You may apply to.
Another object of the present invention is to supply a storage medium storing software program codes for implementing the functions of the above-described embodiments to a system or apparatus, and the computer (or CPU or MPU) of the system or apparatus stores the storage medium. Needless to say, this can also be achieved by reading and executing the program code stored in the.
[0041]
In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.
As a storage medium for supplying the program code, for example, a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, a ROM, or the like can be used.
[0042]
Further, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also an OS (operating system) operating on the computer based on the instruction of the program code. It goes without saying that the case where the functions of the above-described embodiment are realized by performing part or all of the actual processing and the processing is included.
[0043]
Further, after the program code read from the storage medium is written into a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, the function expansion is performed based on the instruction of the program code. It goes without saying that the CPU or the like provided in the board or the function expansion unit performs part or all of the actual processing, and the functions of the above-described embodiments are realized by the processing.
