Description

[0001]
[Industrial application fields]
The present invention relates to a method for storing and recalling drawing images such as maps and design drawings for CAD (Computer Aided Design).
[0002]
In recent years, drawing images such as maps and design drawings are displayed using a computer such as a personal computer, and processing such as recognizing the contents and processing the images is performed.
[0003]
In the original drawing information, a large range is often prepared as one drawing, and when a part of it is enlarged and displayed, the enlargement rate desired by the user for the corresponding part is displayed each time. A screen having a specified enlargement ratio can be obtained by inputting an instruction. However, the drawing so created was only used at that time, and when the same drawing was used again, it was necessary to perform the same processing as the first.
[0004]
[Prior art]
FIG. 12 is an explanatory diagram of a conventional example. 12A is an example of a system configuration, and B to E are examples of procedures for selecting a drawing.
[0005]
This conventional example shows a case where a map is used as a drawing. In the system shown in A, 90 is a display, 91 is an input device such as a mouse and keyboard, and 92 is an information processing device such as a personal computer having a drawing processing function. The device 93 is a map of the map 93a corresponding to each stage, such as all maps in Japan, prefectures, cities, and areas, menu display used to select drawings, targets related to each figure, etc. Is a file device storing character data 93b.
[0006]
When the information processing device 92 of this system selects and displays a map of a desired area, B. of FIG. ~ E. It is performed by the procedure shown in In this case, a menu is displayed on the screen of the display 90. In the case of a map of Japan, a menu (not shown) for selecting prefectures from the whole of Japan is displayed. 12 B.I. A menu screen as shown in Fig. 1 is displayed. From this, one city can be selected. As shown in FIG. 4, a menu for selecting each “ku” in Yokohama, which is a lower hierarchy, is displayed. C. One ward can be selected from the screen. For example, when “Nishi-ku” is selected, the corresponding drawing of Nishi-ku is E.E. As shown in FIG. However, if you want to specify the target (station, park, building, etc.) for the selected area (in this example, Nishi-ku, Yokohama City), the data will As shown in FIG. When a desired target for this menu is selected by the input device 91, or an address of a desired area (including a town name and characters) is input from the input device 91, predetermined map data including the corresponding place is obtained. It can be taken out from the file device 93 and displayed on the display 90 at a fixed magnification (reduction ratio).
[0007]
For a map (graphic image) of a certain area displayed on the display 90, when the user wants to enlarge and view details (reduced and reduced), the enlargement ratio (or reduction ratio) is designated and graphic processing is executed. A corresponding figure is displayed on the display 90.
[0008]
Here, it is assumed that a drawing in which a map of a certain area is partially enlarged is displayed on the display 90. After this, if the user wants to see an adjacent area that is not included in the enlarged drawing, the current screen is deleted, the original drawing is selected, the area is specified again, and the magnification is specified. By doing so, an enlarged drawing of the desired location can be displayed on the display 90. If the adjacent area is not included in the original drawing but is another area, it is necessary to return to the upper selection menu and repeat the same procedure. The same applies to design drawings created by CAD.
[0009]
[Problems to be solved by the invention]
As described above, when performing operations on drawings such as conventional maps and CAD figures, the drawing image obtained by selection is displayed at a predetermined magnification with a predetermined figure, so that the detailed contents are known. For this purpose, an enlarged drawing is created by performing an operation such as designating a place where the user wants to refer to or a magnification. However, even if an enlarged drawing is obtained, the next time you refer to another drawing, the enlarged drawing will be erased, and if you later try to reference the same enlarged drawing again, you must perform the same procedure. ， There was a problem that it took time and effort.
[0010]
Also, if you want to see a screen that is adjacent to a drawing that has been extracted from the file device that is currently displayed, you can view the screen adjacent to it by entering the upper hierarchy (menu screen for selecting a drawing that includes another adjacent region). In this case, there is a problem that if it is desired to see the previously referenced drawing again, it is necessary to return to a higher hierarchy.
[0011]
The present invention provides a drawing image saving / recalling system capable of arbitrarily restoring and displaying an original drawing itself or a drawing created by enlarging or reducing by an operation input when necessary. With the goal.
[0012]
[Means for Solving the Problems]
FIG. 1 is a principle configuration diagram of the present invention.
In FIG. 1, 1 is a processing device, 10 is a drawing application processing unit, 11 is an input determination unit, 12 is a main display drawing saving unit, 13 is a saving area restoring unit, 14 is a saving area designation range restoring unit, and 15 is a saving area. Saving unit, 16 is a saving area name calling unit, 17 is a screen control unit, 18 is a saving drawing data storage unit, 19 is a saving management table for storing management data generated during saving, 2 is a display unit such as CRT or liquid crystal, 2a Is a display screen, 2b is a main display area for displaying the main screen over a wide area of the display screen, and 2c is arranged in a part of the display screen 2a (in the vertical direction on the right side in the example of FIG. 1) and reduced to each. A saving area in which a saving drawing can be displayed, 2d is a work area for displaying the name of the drawing or displaying input data (name, etc.), 3 is a file device, and 3a is mainly composed of bitmap data. Drawing data 3b is character data, 3c saved data, 4 is an input unit including a mouse and a keyboard.
[0013]
The present invention reduces the drawing image displayed in the main display area to the save display area by the operation input and saves it, and then displays all or part of the reduced drawing displayed in the save area while referring to other drawings. Is restored to the main display area by an operation input.
[0014]
[Action]
In FIG. 1, a menu is displayed on the display unit 2 from the drawing data 3 a and character data 3 b held by the file device 3 by the same processing as in the prior art, and a desired screen image is displayed on the display unit 2 by a selection operation from the input unit 4. It is displayed in the main display area 2b in the display screen 2a. When the scale of the drawing displayed in the main display area 2b is large, an enlargement is instructed from the input unit 4, and the position, magnification (a value larger than 1), and rotation (rotation of the drawing) are performed when necessary. When an angle or the like is input, the drawing application processing unit 10 executes a designated enlargement process on the original drawing data and supplies the enlarged image to the screen control unit 17. The screen control unit 17 creates a screen so as to display the enlarged drawing data in the main display area 2 b and outputs the screen to the display unit 2. When the scale ratio is small (when only a narrow range is displayed), when the reduction is instructed from the input unit 4 and the angle to be rotated is input if the magnification is necessary, the corresponding reduction is performed and the main display area is displayed. 2b. Similarly, when the drawing in the main display area 2b is moved, the drawing in which the central portion of the drawing is moved (the hidden portion is displayed) is displayed. Thus, the original drawing, the enlarged, reduced, or moved drawing is displayed in the main display area 2b. Thereafter, the saving and restoring processing according to the present invention will be described in the following (1) to (5).
[0015]
(1) Saving drawings in the main display area
If you want to refer to the drawing (enlarged, reduced, moved, or initially displayed) displayed in the main display area 2b later, you can use the input unit 4 to specify "evacuation" specifying one save area as the destination. The input determination unit 11 determines this and activates the main display drawing saving unit 12. The main display drawing saving unit 12 reduces the display data (drawing image) in the main display area 2b to a size suitable for the designated saving area 2c, and stores the reduced drawing data (bitmap data of the reduced image) as saving drawing data. The target object is automatically selected as the name of the saved drawing, and the coordinates of the original main display area, the name of the saved drawing, and related data (magnification, angle, etc.) are stored in the saved management table 19. Is set. The data (bitmap data) in the saved drawing data storage unit 18 is combined with the drawing data in the main display area 2b and displayed on the display unit 2 so that the screen control unit 17 displays a reduced image in the saved area 2c. Thus, when necessary for different drawings in the main display area 2b, reduced images are sequentially displayed in the different save areas 2c, and each data is held.
[0016]
(2) Display the drawing of the designated save area in the main display area
When the input unit 4 designates one of the save areas 2c on the display screen 2a and instructs the display to the main display area 2b, when the input determination unit 11 determines this, the designated save area is restored. The unit 13 is activated. The save area restoring unit 13 extracts management data (display position, magnification, angle, etc.) of the specified save area 2c from the save management table 19, and uses the data to display the drawing data 3a and the character data 3b as the display control unit 17. Is output to the main display area 2b. As a result, the display data displayed in the main display area 2b until then is replaced with the contents obtained by expanding the screen data of the save area 2c.
[0017]
(3) Display the designated area of the save area in the main display area
Select one of the save areas 2c on the display screen 2a of the display section 2 from the input section 4, specify the position representing the area (range) in the display of the save area 2c, and instruct display on the main display area 2b When the input is performed, the input determination unit 11 determines this, and the save area designation range restoration unit 14 is activated. The save area designated range restoring unit 14 obtains the coordinates of the position representing the area in the save area 2c designated using the save management table 19 and the magnification for expanding the area to the main display area 2b. Using the data, drawing data 3a and character data 3b are output to the main display area 2b by the screen controller 17. As a result, the display data that has been displayed in the main display area 2b up to that point is replaced with the contents that apparently expand the designated range of the save area 2c.
[0018]
(4) Saving the save area
With reference to the drawing in the processing device 1 and processing of saving drawing data during execution of the drawing, the saving area 2c is displayed before the processing is completed in a state where the reduced screen is displayed in the saving area 2c of the display screen 2a. When it is desired to save data for saving (evacuation drawing data and related data), the input unit 4 instructs to save data of all the saving areas 2c. When the input determination unit 11 determines this instruction, the save area storage unit 15 is activated. The save area storage unit 15 generates a save file name input screen. When a file name is input in the state displayed on the display screen 2a, all the save drawing data and the save drawing data in the save drawing data storage unit 18 are stored according to the file name. Data in the save management table 19 is saved as saved data 3 c of the file device 3. The stored data 3c can be called to the processing device 1 at the next activation and displayed in the save area.
[0019]
(5) Recalling the drawing name of the save area
Applicable when you want to know each drawing name (name of place in the case of a map, name of function or position in the case of a blueprint) when the reduced screen is displayed in each of the plurality of save areas 2c of the display screen 2a. The name calling is instructed by designating the save area 2c. In this case, when the input determination unit 11 detects this instruction, the save area name calling unit 16 is activated. When the save area name calling unit 16 is activated, the name of the designated save area 2c is taken out from the save management table 19 that stores it together with other related data, and is controlled by the screen control unit 17 to be displayed in the work area 2d. Thereby, the name of each save area 2c can be known.

[0029]
When the drawings in the rectangles indicated by a to d in (2) in FIG. 5 are to be saved in the saving area according to the present invention, the rectangular drawings (main display areas) indicated by a to d in (2) are displayed. As shown in (3), the area is reduced to a rectangle represented by a 'to d' of the saving area, and as a part of the saving management data, the coordinates of a in (2) (X0, Y0: where these coordinates are latitude, Longitude or coordinates based on the origin of the original drawing) and the magnification (1.2 in this example) are stored. Details of this processing will be described in a processing flow (see FIG. 6) of an embodiment described later.
[0030]
FIG. 6 is a processing flow of the embodiment. This processing flow mainly shows processing related to saving and restoration according to the present invention, and will be described below with reference to FIGS.
At the start of this processing flow, it is assumed that an enlarged drawing is displayed in the main display area 41 of the display screen 40 of the display 24. Note that a reduced drawing or a drawing that is the same size as the original drawing may be displayed.
[0031]
In the state of waiting for input (S1 in FIG. 6), it is determined that an input occurs (S2 in the same). In this embodiment, the mouse 25 is operated and dragged from the main display area 41 to one selected save area (for example, 42-1 in FIG. 4), or simply right-clicked on the selected save area (mouse If the operation button on the right side of 25 is clicked twice), it is determined that the instruction is to save the drawing in the main display area.
[0032]
In this case, the save ID that is the identification number of the selected save area is acquired (S3 in FIG. 6), and the X and Y coordinates (same as X0 and Y0 in FIG. 5) in the upper left of the drawing display area are acquired (see FIG. 5). 6 (S4), and then the drawing magnification of the current main display area is acquired (S5). Thereafter, if the drawing displayed in the main display area is rotating and displaying the original drawing, the rotation angle is acquired (S6). Next, a target acquisition process is performed to automatically set a name for the drawing displayed in the save area (S7). Details of this process will be described with reference to FIG. 8 described later. By this target acquisition process, one of the station name, building, road, etc. is acquired as a target for the enlarged main display area drawing. , This target is the name of the drawing. Next, each acquired data is registered in the save management table (S8).
[0033]
FIG. 7 shows the configuration of the save management table. In this save management table, an area for storing a save ID, name, display position upper left X coordinate, Y coordinate, magnification, and angle is provided corresponding to one save area. Is provided.
[0034]
Next, the figure displayed in the main display area in the save area having the save ID acquired in S3 in FIG. 6 is compressed to the size of the save area (using the conventional graphic processing function), and the obtained figure is saved. The screen is displayed in the area (S9). Further, the graphic (bitmap) created (reduced) for the save area is stored in the memory 21 for later scrolling of the save area by the scroll bar 43 and saving of the save area.
[0035]
Next, in the above input determination (S2 in FIG. 6), one save area (for example, 42-1 in FIG. 4) selected by the mouse 25 is dragged to the main display area or simply selected. If left is double-clicked, it is determined that the instruction is to restore the figure in the save area to the main display area.
[0036]
In this case, the selected evacuation ID is acquired (S11 in FIG. 6), the upper left coordinates, the magnification, and the rotation angle are acquired from the corresponding evacuation management table (see FIG. 7) (S12 to S14). Using the values, the drawing data 3a and the character data 3b are displayed in the main display area (S15).
[0037]
Next, in the input determination, when a certain range within the save area is dragged with the mouse 25 (designated from one vertex to the other vertex on the diagonal of the rectangle), it is determined that the designated range within the save area is restored. In this case, the save ID of the designated save area is acquired (S16 in FIG. 6), and the relative coordinates of the dragged area (rectangle) are acquired (S17). Next, coordinates are calculated when the area represented by the relative coordinates in the acquired save area is converted into the area of the main display area (S18), and the magnification of the original save area and the specified range are set as the main display area. A new magnification is calculated using the magnification for enlarging to (S19), and an angle is obtained (S20). Drawing data 3a and character data 3b are displayed in the main display area using the magnification and angle acquired in this way (S21).

The content is determined to be an instruction to save in the file device (S2 in FIG. 6). In this case, a save file name designation screen is first displayed (S22 in FIG. 6).
[0039]
The saved file name designation screen is displayed in the work area 44 shown in FIG. 4. At this time, when the user inputs a file name from the keyboard 26, it is displayed in the work area 44 and read into the memory (S23). When the input is completed, the file name designation screen is erased (S24 in the same), and subsequently, a process of saving the graphics (bitmap) of each save area and the contents of the save management table together with the file name in the designated file device 23 is performed. (S25).
[0040]
Next, the processing content of the target acquisition executed in step 7 of FIG. 6 will be described.
FIG. 8 is an explanatory diagram of target acquisition. Is a processing flow, B.I. Is a priority table used for target acquisition. B. The priority table shown in FIG. 4 is a table in which which of the types such as a station, a road, a building, and an area name is preferentially selected when a target is selected. The target included in the graphic data of each map is C. Are stored in the target file shown in FIG. 2, and the type is set as the data of each target.
[0041]
In FIG. 8, it is first determined whether the priority table is the last item (S1 in FIG. 8). If it is not the last, the type on the priority order is read (S2), and the target file (C. in FIG. 3) is read. The target of the read type is searched (S3). It is determined whether or not there is a corresponding target by the search (S4). If there is no corresponding target, the same processing is performed for the next priority type in the priority table. (S5), if there are multiple objects, select one closest to the center of the displayed drawing (S6), and if there is one or only one, select it as the target Determine (S7). If there is no target even after searching for the last priority, the process ends.
[0042]
Next, if you want to know what the drawing of the reduced image of the save area represents, you can know its name as follows.
In the input determination (S2) shown in FIG. 6, when an instruction to display a name is detected, the instruction is executed in a state where reduced images are displayed in a plurality of save areas on the display screen. This is done by moving the mouse cursor so that it is positioned in the area of the specific save area where the user wants to know and operating (clicking) the mouse 25. If it is determined that the instruction is to display the name of the save area, the name portion in the data for the specified save area in the save management table (FIG. 7) is read out, and the work area on the screen is displayed. (44 in FIG. 4) is displayed, and this display is erased in a fixed time.
