BACKGROUND OF THE INVENTION
In the present invention, raster data composed of a set of dot data obtained by reading a paper drawing with a reading device such as a scanner, and vector data specified by coordinate values, necessary parameters, and the like are mixed. The present invention relates to a drawing file generation method for generating a drawing file of another file format from an integrated drawing file, and in particular, generates a drawing file of a format that can be directly used in a CAD system or the like from an integrated drawing file, and a raster data editing device The present invention relates to a drawing file generation method capable of improving data compatibility from a computer to a CAD system or the like and a medium storing the program.
[0002]
[Prior art]
Conventionally, drawing data created using a CAD system is stored in the form of vector data specified by necessary parameters such as a start point, an end point, a length, and an angle. It will be done directly. On the other hand, there is also a demand for effective use of a huge number of paper drawings created in the past by creating a new drawing with a slight modification to the paper drawing. In this case, an existing paper drawing is read by a drawing reading device such as a scanner, and a new drawing is created by adding necessary corrections and corrections to the obtained raster data. Such raster data editing devices are limited in operations such as erasing, copying, pasting, rotating, enlarging, and reducing dot data. Therefore, the raster data editing apparatus is easier to operate than a CAD system capable of editing vector data. It is far inferior.
[0003]
In view of this, an editing apparatus has been developed in which raster data obtained by reading a paper drawing with a scanner is converted into vector data, and editing using vector data is possible. However, since the editing device described above converts all of the read raster data into vector data, it takes time for conversion and unintentional conversion to vector data occurs everywhere. There is a problem that it takes time and effort.
[0004]
In order to solve this problem, the present applicant converts raster data into vector data only for a specified portion of raster data obtained by reading a paper drawing with a scanner, and partially applies the vector data. A raster data editing apparatus that enables editing operations has been proposed and filed (Japanese Patent Application No. 11-105057). According to this raster data editing apparatus, only the portion necessary for editing needs to be converted into vector data, so that the conversion process does not take time, and correction work for the erroneous conversion portion is almost unnecessary, and vector data Since the editing operation can be performed, there is an advantage that the editing operation is easy and the editable range is wide. In addition, the applicant can improve the efficiency of editing operations using existing CAD files and the like based on the fact that raster data and vector data can be mixed in the raster data editing apparatus. A raster data editing apparatus has also been proposed and filed (Japanese Patent Application No. 11-182291). According to this raster data editing device, the vector data from the outside can be taken into the editing base raster data, the coordinate system can be matched and pasted at any position, so existing CAD files etc. can be used effectively Since raster data and vector data are stored in association with each other by an integrated file, raster data and vector data can be edited quickly by direct access to the integrated file, and operability is greatly improved. There is an advantage of doing. In recent years, it has become possible to refer to raster data on vector data handled by a CAD system by using a so-called attach function for pasting image data consisting of raster data as vector data.
[0005]
[Problems to be solved by the invention]
By the way, in the raster data editing apparatus described above, raster data and vector data can be mixed and associated by an integrated file. Therefore, the integrated file created by this raster data editing apparatus can be attached to the image data described above. If it can be used in a CAD system having a function, it is possible to further effectively use various drawing patterns.
[0006]
The present invention has been made in view of the above points, and a drawing file generation method for generating a drawing file in a format that can be used in a CAD system having an image data attaching function from drawing data in which raster data and vector data are mixed. And a medium for storing the program.

[0019]
FIG. 2 is a block diagram showing a part of the internal configuration of the editing unit 5 and the storage medium 7 of this raster data editing apparatus.
[0020]
Raster data such as the image data 1 of the drawing read by the scanner 2 is input to the raster data editing unit 15 via the file input / output unit 17 in the editing unit 5, and a raster database (hereinafter “ RDB ”). The file input / output unit 17 inputs / outputs data files input / output to / from the editing unit 5 and the storage medium 7. The raster data editing unit 15 is in charge of raster data editing processing in the raster data editing apparatus, and exchanges raster data with the RDB 20 as necessary. On the other hand, the CAD file supplied from the existing external CAD system 6 is stored in a CAD file database (hereinafter referred to as “CDB”) 19 in the storage medium 7 via the file input / output unit 17. When the editing process is performed using the CAD data of the CAD file stored in the CDB 19, the editing unit 5 first reads out the CAD data stored in the CDB 19. The CAD data read into the editing unit 5 is input to the vector data pasting unit 13 in the editing unit 5 including the coordinate conversion unit 14. The coordinate conversion unit 14 of the vector data pasting unit 13 performs processing for converting the coordinate system of CAD data from the CDB 19 input to the vector data pasting unit 13 into the coordinate system of raster data. The vector data pasting unit 13 stores vector data composed of the CAD data subjected to coordinate transformation by the coordinate transformation unit 14 in a vector database (hereinafter referred to as “VDB”) 21 in the storage medium 7. The vector data stored in the VDB 21 is input to the vector data editing unit 16 in the editing unit 5 and is appropriately subjected to editing processing by the vector data editing unit 16.

It is always used interchangeably in the data editing device.
[0021]
On the other hand, the RV integrated file database (hereinafter referred to as “RVIDB”) 12 provided in the storage medium 7 stores the RV integrated file created by the RV integrated file creating unit 23. The RV integrated file creation unit 23 reads raster data and vector data from the raster data editing unit 15 and the vector data editing unit 16, respectively, and associates the vector data with the raster data to mix the raster data and vector data. Create an RV integration file. At the time of actual editing work by the raster data editing apparatus, the editing unit 5 refers to the header information of the RV integrated file stored in the RVIDB 12, and stores the raster data stored in the RDB 20 and the vector data stored in the VDB 21, respectively. The RV integrated file can be directly read from the RVIDB 12, and the RV integrated file can be separated into raster data components and vector data components and edited as appropriate. In addition, the data edited in this way can be freely stored in the RDB 20 or VDB 21 or can be stored in the RVIDB 12 as an RV integrated file.
[0022]
FIG. 3 is a diagram showing the configuration of the RV integration file described above.
As shown in the figure, the RV integrated file (for example, file name “ABC.RVD”) 40 is mainly composed of a header information area 30, a raster data information area 31, and a vector data information area 32. It consists of a file structure with one area. In the header information area 30, version data 33 indicating the version of the RV integrated file 40, vector element number information 34 indicating the number of vector data elements in the RV integrated file 40, and other information 35 are set. In the raster data information area 31, information related to raster data 37 in the RV integrated file 40 is stored. In the vector data information area 32, vector data 36 of the RV integrated file 40 is stored.₁, 36₂, 36_Three, ..., 36_nAre stored as a plurality of vector data indexes (vectors Idx1, Idx2, Idx3,..., Idxn). These vector data 36₁~ 36_nIs associated with the raster data 37 constructed in the internal area of the memory 4 in the editing unit 5 so as to be developed in the memory 4 with different layers, for example, when editing processing is performed based on the RV integrated file 40 It has been. Thereby, the vector data is arranged on the same coordinate system 38 as the raster data 37 there.
[0023]
In this raster data editing apparatus capable of performing such editing processing, not only can a CAD file sent from the CAD system 6 be used, but also raster data and vector data created in the raster data editing apparatus can be used. The RV integrated file 40 composed of mixed data can be directly sent as a file usable on the CAD system 6 side. Therefore, in the editing unit 5 of this raster data editing apparatus, a file generation unit 22 is provided for reading the RV integrated file 40 from the RVIDB 12 and generating a data file in a file format usable on the CAD system 6 side. ing.
[0024]
Next, a file generation process in the file generation unit 22 will be described.
FIG. 4 is a block diagram showing a part of the internal configuration of the file generation unit 22 in the editing unit 5, and FIG. 5 is a flowchart of the file generation processing in the file generation unit 22.
[0025]
First, the file generation unit 22 reads the RV integrated file 40 from the RVIDB 12 (S1). The RV integrated file 40 read from the RVIDB 12 to the file generation unit 22 is input to the file analysis unit 41, and the file analysis unit 41 analyzes various information of the file (information such as file structure and file size). (S2). The file information of the RV integrated file 40 analyzed by the file analysis unit 41 is output to the CPU 3 and used for editing processing and the like. Further, the file analysis unit 41 appropriately divides the raster data component and the vector data component of the RV integrated file 40 based on the analyzed file information of the RV integrated file 40 (S3). The RV integrated file 40 thus analyzed by the file analysis unit 41 and appropriately divided is then input to the file information editing unit 42. In the file information editing unit 42, it is first determined whether or not to perform an editing process for adding the file information of raster data to the file information of vector data (S4). For example, when there is no predetermined input signal from the input unit 9, no particular editing process is performed on the RV integrated file 40, but when there is a predetermined input signal from the input unit 9, the above editing process is performed. It is a condition of applying. In this case, a series of processes of extracting the relative path and raster data position information of the file by referring to the file information of the raster data in the RV integrated file 40 based on the input signal, and writing them into the file information of the vector data. An edit command of executing the attach command 43 including (43a to 43c) and adding file data of raster data to the vector data (S5) is performed. Thereafter, the RV integrated file 40 is used by the raster file generation unit 44 and the vector file generation unit 45 to generate a raster file and a vector file, respectively. The raster file generation unit 44 extracts the raster data component of the RV integrated file 40 in the file information editing unit 42, generates a file (for example, a TIFF file) composed of raster data, and outputs the file to the file input / output unit 17. . On the other hand, the vector file generation unit 45 extracts the vector data component of the RV integrated file 40 in the file information editing unit 42, generates a file (for example, a DXF file) composed of vector data, and sends it to the file input / output unit 17. Output (S6). At this time, if it is selected that the editing process is performed in step S4 and the raster data file information is added to the vector data in step S5, the vector file generation unit 45 converts the raster data file information into the vector data. A vector file added to the data file information is generated and output to the file input / output unit 17.
[0026]
Next, a file output operation accompanied by a file generation operation in the raster data editing apparatus described above will be described. This raster data editing apparatus is a “single file output” that outputs an active drawing currently displayed on the display screen of the display unit 8 as a file and a “continuous file output” that outputs a plurality of saved drawings as a file. The two output modes are provided. First, when the raster data editing apparatus is activated, a main operation screen 50 as shown in FIG. 6 is displayed on the display screen of the display unit 4. The main operation screen 50 is particularly useful among a title bar 51 for displaying the name of the activated software, a menu bar 52 and a tool bar 53 for selecting the function of the activated software, and software functions. Function toolbar 54 for selecting functions, layer toolbar 55 for performing operations related to layers, status bar 56 for displaying various modes, units, scales, and the like, a work area for displaying read drawing files and the like for editing 57 and the like. Each menu item in the menu bar 52 is displayed in a character display, and each tool item in the tool bar 53 and the function tool bar 54 is displayed in a predetermined icon display, thereby improving the function operability.
[0027]
In the “single file output” mode, a “single” command is issued from the “file output” item of the file menu 52 a of the menu bar 52 displayed on the main operation screen 50 in order to generate and output a file currently being worked on. select. When the fact that the “single” command is selected is input to the input unit 9, the information is transmitted to the CPU 3, and the single operation as shown in FIG. 7 is displayed on the main operation screen 50 displayed on the display unit 8. A file output dialog 60 is displayed. The single file output dialog 60 includes a file name input box 61 for designating a file after generation, and a file selection box 62 for selecting the type of file after generation from file types such as DXF and DWG. , A layer division designation box 63 for separately generating data layers according to a designation method, a setting button 64 for displaying a “layer setting” dialog for performing detailed settings for layer division, for example, generating only vector elements when checked A generation output element specification item 65 for specifying a generation output element such as output, and when layer generation is “single layer” or “layer name division” and a DXF or DWG format file is generated, the layer name of the data is changed. Layer name setting item 66 for setting whether to use, DXF, DWG format file Image file name output setting item 67 for setting whether or not to use a raster file as a data image, unit system designation box 68 for designating a unit system of a drawing, DXF, DWG format It includes components such as a polyline vertex number designation box 69 for designating a limit on the number of vertexes of a polyline when generating a file, and a generation setting file display box 70 for displaying a file name of a current generation setting. It is configured.
[0028]
  On the other hand, in the “continuous file output” mode, the “continuous” command is selected from the “file output” item of the file menu 52a in order to generate and output the selected files. The description of the same parts as those in the “single file output” mode is omitted. When the fact that the “continuous” command is selected is input to the input unit 9, the information is transmitted to the CPU 3, and the main operation screen is displayed.50 topThen, a continuous file output dialog 71 as shown in FIG. 8 is displayed. The continuous file output dialog 71 mainly specifies an input file setting box 72 for specifying a file to be generated, an output destination setting box 73 for specifying an output destination directory after generation, and various conditions for file generation. And a generation setting box 74 for doing this. The input file setting box 72 includes a generated file list display box 75 for displaying a list of files to be generated, a registration button 76 for displaying a “open file” dialog and adding a file to be generated to the file list, and a generated file list. A cancel button 77 for canceling the file selected in is provided. The output destination setting box 73 is provided with a reference button 78 for displaying a “conversion destination directory designation” dialog. On the other hand, the generation setting box 74 includes a generation setting file display box 79 for displaying the current generation setting file name, and a file for selecting the file type after generation from, for example, DXF and DWG file types. Format specification box 80, unit systemSpecifiedBox 81, layer division specification box 82, setting button 83, layer name setting item 84, image file name output setting item 85, conversion mode specification box 86 for specifying a conversion mode at the time of file generation, polyline vertex number specification box 87 Also, it is configured to include components such as a filter designation box 88 for designating filter processing at the time of file generation and preventing raster data smaller than the designated vertical and horizontal rectangles from being converted.
[0029]
  In these “single” and “continuous” file output dialogs 60 and 71, one of common command selection items is “image file name output setting”. By enabling (turning on) this image file name output setting, as shown in FIG.9A predetermined input signal is output to the file information editing unit 42, and an attach command 43 for adding the file information of the raster file to the file information of the vector file operates. In the attach command 43, first, a raster file reference command 43a is written in the file information of the vector file to refer to the raster file to be added, and then the location (file name) where the raster file is stored is designated. The relative path 43b to be written is written. Then, raster data position information 43c indicating where the raster data in the raster file is displayed as background image data of the vector data in the vector file is written. Further, in this attach command 43, the same file name as the designated setting file name at the time of generation is designated as a raster file to be referred to. For this reason, in this raster data editing apparatus, for example, as shown in FIG. 9A, from the drawing data composed of the RV integrated file 40 displayed on the display area 90, FIGS. ), The file generation unit 22 can generate a vector file including the vector data 91 and 92 and a raster file including the raster data 93, and the attach command 43 is executed to generate the file. In this case, the command 43a and the like are automatically written in the vector file so as to refer to the file information of the raster file. Therefore, when editing the vector data of the vector file, the raster file can be stored without using the so-called attach function. The raster data can be used in the state pasted as background image data. As a result, as shown in FIG. 10A, for example, the generated vector file and raster file are separately output to the CAD system 6 and the vector data 91 and 92 are displayed in the display area 95 on the CAD system 6 side. In addition, when the file information of the raster file is added to the output vector file, the raster data 93 can be obtained by simply using the vector file in the CAD system as shown in FIG. It can be displayed as a background. For this reason, as shown in FIG. 5C, the CAD system 6 can also functionally perform an editing process using the RV integrated file 40. In this way, since various drawing files can be directly output to the CAD system, drawing data in which raster data and vector data are mixed can be used effectively, and a raster data editing apparatus and CAD can be used. Data compatibility with the system can be improved, and overall efficiency of drawing editing work can be improved.
[0030]
