Technical Field

[0001] The embodiments of the present invention relate to computer technology, and more particularly to a method, apparatus, device and storage medium for transferring drawings. Background Technology

[0002] Graphical configuration software is a data visualization and integration tool that enables component interaction through drag-and-drop layout and configuration, and provides a visual and controllable page in a graphical way, thereby enabling the monitoring and control of real devices.

[0003] Currently, when migrating drawings that are only for display and cannot be edited to graphical configuration software, it is usually necessary to manually draw logical drawings with element connection relationships corresponding to the vector graphics in the drawing in the graphical configuration software.

[0004] However, in the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0005] The existing method of transferring drawings requires manual redrawing, which is time-consuming and labor-intensive, reducing the efficiency of drawing transfer. Summary of the Invention

[0006] This invention provides a drawing migration method, apparatus, device, and storage medium to simplify drawing migration operations and improve drawing migration efficiency.

[0007] In a first aspect, embodiments of the present invention provide a drawing migration method, including:

[0008] Obtain the first drawing file in the first drawing file format corresponding to the drawing to be migrated;

[0009] Based on the second graphic file format, the vector graphic elements in the first graphic file are converted to obtain a second graphic file in the second graphic file format.

[0010] The second graphic file is parsed, and the parsed target vector graphics are rendered onto the first canvas;

[0014] The first drawing file acquisition module is used to acquire the first drawing file in the first drawing file format corresponding to the drawing to be migrated.

[0015] The first graphic file conversion module is used to convert the vector graphic elements in the first graphic file according to the second graphic file format to obtain a second graphic file in the second graphic file format.

[0016] The target vector graphics rendering module is used to parse the second graphic file and render the parsed target vector graphics onto the first canvas;

[0025] By acquiring a first graphic file in a first graphic file format corresponding to the drawing to be migrated, and converting the vector graphic elements in the first graphic file according to a second graphic file format, a second graphic file in the second graphic file format is obtained.

Thus, through user selection operation and / or element template matching method, the vector graphics in the drawing to be migrated can be split into elements without manual redrawing, simplifying the drawing migration operation and improving the efficiency of drawing migration.

[0031] Figure 5 This is a schematic diagram of the structure of an electronic device provided in one embodiment of the present invention. Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] Figure 1This is a flowchart illustrating a drawing migration method according to an embodiment of the present invention. This embodiment is applicable to situations where drawings intended only for display and not for editing are migrated to graphical configuration software, particularly CAD drawings. The method can be executed by a drawing migration device, which can be implemented in software and / or hardware and integrated into an electronic device. Figure 1 As shown, the method specifically includes the following steps:

[0034] S110. Obtain the first drawing file in the first drawing file format corresponding to the drawing to be migrated.

[0035] In this context, "drawings to be migrated" refers to drawings that need to be transferred to graphic configuration software for display purposes only and cannot be edited. For example, drawings to be migrated could be CAD drawings created using CAD drawing software. These drawings contain generated vector graphics. The first graphic file format can refer to the file storage format of the vector graphics in the drawings to be migrated. The graphic configuration software cannot recognize vector graphics in the first graphic file format. For example, the first graphic file format could be the DXF (Drawing Exchange Format) format corresponding to the CAD drawing, and the corresponding first graphic file could be the DXF file corresponding to the CAD drawing. The DXF format is stored in ASCII code and can be read and edited using Notepad. Accordingly, a DXF file is a graphic representation file stored in ASCII code format and can be read and edited using Notepad.

[0036] Specifically, drawing software can be used to create drawings containing vector graphics, such as CAD drawings, and the first graphic file in the first graphic file format, such as the DXF file corresponding to the CAD drawing, can be imported into the graphic configuration software so that the drawing can be converted based on the DXF file in the graphic configuration software to obtain logical drawings with logical connections.

[0037] S120. Based on the second graphic file format, the vector graphic elements in the first graphic file are converted to obtain a second graphic file in the second graphic file format.

[0038] The second graphics file format can refer to a file storage format that can recognize vector graphics in graphics configuration software. For example, the second graphics file format can refer to the Scalable Vector Graphics (SVG) format. Vector graphics elements can be element objects used to compose vector graphics. For example, vector graphics elements can include, but are not limited to: lines, line segments, circles, ellipses, arcs, and splines. The representation of the same vector graphics element differs in different graphics file formats. For example, different element names can be used to represent the same vector graphics element. For instance, in DXF format, the element name for the vector graphics element "line" is LINE, while in SVG format, the element name for the vector graphics element "line" is Line. Different graphics file formats also correspond to different coordinate systems, thus requiring conversion of the element coordinate values ​​for each vector graphics element. For example, in DXF format, the origin of the coordinate system is at the lower left corner of the screen, with the positive X-axis pointing to the right and the positive Y-axis pointing upwards. In SVG format, the origin of the coordinate system is at the upper left corner of the screen, with the positive X-axis pointing to the right and the positive Y-axis pointing downwards.

[0039] Specifically, existing format conversion tools can be used to convert a first graphic file in a first graphic file format into a second graphic file in a second graphic file format. Alternatively, based on the element conversion relationship between the second and first graphic file formats, the vector graphic elements in the first graphic file can be renamed and their coordinates transformed to obtain a second graphic file in the second graphic file format.

[0040] For example, S120 may include: converting the vector graphic element names in the first graphic file based on the correspondence between the vector graphic element names in the first graphic file format and the vector graphic element names in the second graphic format; converting the element coordinate values ​​of the vector graphic elements in the first graphic file based on the first graphic coordinate system corresponding to the first graphic file format and the second graphic coordinate system corresponding to the second graphic file format; and determining the graphic file obtained after converting the element names and element coordinate values ​​as the second graphic file under the second graphic file format.

[0041] Specifically, based on the correspondence between vector graphic element names in the first graphic file format and those in the second graphic format, the element name of each vector graphic element in the first graphic file is converted to its corresponding name in the second graphic format, thus achieving element name conversion and translation. Based on the first graphic coordinate system corresponding to the first graphic file format and the second graphic coordinate system corresponding to the second graphic file format, a coordinate transformation matrix can be determined. Based on this matrix, the element coordinate values ​​of each vector graphic element in the first graphic file are transformed to obtain element coordinate values ​​in the second graphic coordinate system, thus achieving coordinate system conversion of element coordinate values. After completing the conversion of element names and element coordinate values, the resulting graphic file can be defined as a second graphic file in the second graphic file format, thereby converting and translating vector graphics from drawings in the first graphic file format to drawings in the second graphic file format, such as converting and translating vector graphics from CAD drawings to SVG drawings.

[0042] It should be noted that the second graphic file obtained after conversion is only a collection of elements; the element combinations have not yet been mapped to specific device primitives. For example, the SVG file obtained after conversion is shown below:

[0043] <svg viewBox="0 0 800 600"version="1.1"stroke-linecap="round"stroke-linejoin="round"fill-rule="evenodd"xml:space="preserve">

[0044] <defs>

[0045] <clipPath id="clipId0">

[0046] <path d="M0,600 800,600 800,0 0,0z" / >

[0047]

[0048] < / defs>

[0049] <gclip-path="url(#clipId0)"fill="none"stroke="rgb(0,0,0)"stroke-width="0.1" / >

[0050] <path d="M26.1687,572.645 26.8215,571.992 787.167,571.992 787.82,572.645z" / >

[0051] S130. Parse the second graphic file and render the parsed target vector graphic onto the first canvas.

[0052] The target vector graphic can refer to the vector graphic that needs to be migrated. The canvas can be a drawing used to display the graphic. For example, the canvas can be, but is not limited to, a Canvas. The first canvas can be a drawing used to display the target vector graphic of the primitives to be segmented, so as to allow subsequent editing and extraction operations.

[0053] Specifically, because the second graphic file format (such as SVG) does not provide pixel-level processing and cannot obtain pixel data at specific locations in the image, a canvas plugin, such as fabric.js, can be used to parse the second graphic file into JavaScript drawing code corresponding to the target vector graphics. By executing the JavaScript drawing code, the target vector graphics can be rendered onto the first canvas, such as the first Canvas. For example, Figure 2 An example of a drawing migration process is given, such as Figure 2 As shown, the target vector graphics in the drawing to be transferred are rendered on the first canvas, so that the user can select elements on the first canvas.

[0054] S140. Based on the user selection operation triggered on the first canvas and / or the primitive template matching method, determine the target primitive corresponding to the target vector graphic, and render the target primitive onto the second canvas.

[0055] In this context, a primitive can refer to a configuration element used to represent a device graphic. It should be noted that primitives can be closed or open, such as pins with two ends. For example, a resistor primitive can be constructed using a combination of straight lines, rectangles, and straight lines to create the resistor graphic. A target primitive can refer to the primitives contained within a target vector graphic. A target vector graphic contains multiple target primitives. The second canvas can be a drawing used to display the segmented target primitives.

[0056] Specifically, all target primitives in the target vector graphic can be obtained through user selection operations triggered on the first canvas and / or through primitive template matching. For example, if the primitive template library does not contain primitives in the drawing domain to be migrated, the user can select primitives on the target vector graphic displayed on the first canvas based on business needs. For instance, the user can click or circle graphic parts belonging to the same primitive, thereby combining the set of target elements selected by the user each time into a corresponding target primitive. For example, such as... Figure 2 As shown, the user has circled the diode section of the circuit on the first canvas, for example... Figure 2The dashed box in the image allows the user to select a target graphic element, namely a diode graphic element. This enables the user to directly trigger a selection operation on each graphic element on the first canvas, thus separating all target graphic elements in the target vector graphic. This allows for rapid drawing migration even when there are no domain graphic elements in the graphic configuration software.

[0057] For example, if the graphic element template library contains graphic elements in the drawing area to be migrated, the graphic element templates in the graphic element template library can be matched with the target vector graphics on the first canvas to automatically match the target graphic elements in the target vector graphics without the need for manual drawing of the target graphic elements.

[0058] Furthermore, user selection and primitive template matching can be combined to accurately extract all target primitives from the target vector graphic. For example, after a user selects a target primitive on the first canvas, the selected primitive can be used as a template and matched with the target vector graphic to automatically extract other target primitives within the target vector graphic. This reduces the number of times the user needs to select primitives, thereby improving primitive extraction efficiency. For example, ... Figure 2 As shown, the diode element selected by the user is used as the element template for template matching to obtain the matched resistor element and capacitor element.

[0059] This embodiment can create a new second canvas, such as a second Canvas, within the DOM (Document Object Model) tree to hold the split target primitives. By rendering each split target primitive onto the second canvas for display, the user can be informed of the splitting process. This embodiment can render the corresponding target primitives according to their original graphic positions in the imported drawing, displaying the target primitives at the same locations to simplify subsequent connection operations and further improve drawing migration efficiency.

[0060] S150. Connect the target elements on the second canvas to obtain the logic drawing to be migrated to the graphic configuration software.

[0061] The graphical configuration software can be, but is not limited to, web-based visual graphics drawing software. Logical drawings can refer to drawings with logical connections between graphic elements, that is, visual drawings created within the graphical configuration software.

[0062] Specifically, after extracting all target elements from the target vector graphic, on the second canvas, lines can be connected and filled in according to the original graphic positions to update the drawing to be migrated imported into the graphic configuration software into a logical drawing with logical connections between elements, thus completing the drawing migration operation. Through format conversion and user selection of elements, drawings from the original work area can be quickly migrated to the technologically updated graphic configuration software, reducing dependence on starting domain elements and minimizing the workload of building from scratch, thereby improving drawing migration efficiency.

[0063] The technical solution of this embodiment obtains a first graphic file in a first graphic file format corresponding to the drawing to be migrated, and converts the vector graphic elements in the first graphic file according to a second graphic file format to obtain a second graphic file in the second graphic file format. The second graphic file is parsed, and the parsed target vector graphic is rendered onto a first canvas. Based on the user selection operation and / or graphic element template matching method triggered on the first canvas, the target graphic element corresponding to the target vector graphic is determined, and the target graphic element is rendered onto a second canvas. All target graphic elements on the second canvas are connected to obtain the logical drawing to be migrated into the graphic configuration software. Thus, through the user selection operation and / or graphic element template matching method, the vector graphics in the drawing to be migrated can be split into graphic elements without manual redrawing, simplifying the drawing migration operation and improving the drawing migration efficiency.

[0064] Based on the above technical solution, after S140, it may also include: displaying the primitive confirmation information corresponding to the target primitive after each rendering; and deleting the target primitive that the user confirmed as incorrect in response to the primitive error command triggered by the user based on the primitive confirmation information.

[0065] The primitive confirmation information can be used to prompt the user whether the target primitive rendered in this instance is the primitive that needs to be separated. The primitive error instruction can be used to indicate that the target primitive rendered in this instance is not the primitive that needs to be separated.

[0066] Specifically, after each rendering of a target element on the second canvas, corresponding element confirmation information can be displayed to prompt the user for element confirmation. The user can trigger an element error command by clicking the "Error" button on the displayed confirmation information. If an error command is detected, the target element confirmed as incorrect can be deleted from the second canvas for re-splitting. Alternatively, the user can trigger a correct command by clicking the "Correct" button, allowing the correctly confirmed target elements to continue to be displayed on the second canvas. Once all target elements in the target vector graphic have been split and confirmed as correctly split, connections can be made between all correctly confirmed target elements on the second canvas, ensuring the accuracy of the drawing migration.

[0067] Figure 3 This is a flowchart of another drawing migration method provided by an embodiment of the present invention. Based on the above embodiments, this embodiment describes the process of determining the target graphic element through user selection, and further describes the process of determining the target graphic element through graphic element template matching. Explanations of terms that are the same as or corresponding to those in the above embodiments are not repeated here.

[0068] See Figure 3 Another drawing migration method provided in this embodiment specifically includes the following steps:

[0069] S310. Obtain the first drawing file in the first drawing file format corresponding to the drawing to be migrated.

[0070] S320. Based on the second graphic file format, the vector graphic elements in the first graphic file are converted to obtain a second graphic file in the second graphic file format.

[0071] S330. Parse the second graphic file and render the parsed target vector graphic onto the first canvas.

[0072] S340. Based on the user selection operation triggered on the first canvas, determine the set of target elements selected by the user in the target vector graphics.

[0073] Specifically, users can select graphic elements on the target vector graphics displayed on the first canvas based on business needs. For example, users can click or circle parts of graphics belonging to the same graphic element. Mouse events can be listened to on the first canvas, such as the mouseup (click start event), mousedown (click end event), and mousemove (click move event). By listening to these mouse events, the user can determine the graphic area selected or circled in the current click or circle, and all elements within that area can be identified as the target element set selected by the user in this instance.

[0074] S350. Combine the set of target elements to determine the target primitive selected at this time, and render the target primitive selected at this time onto the second canvas.

[0075] Specifically, the set of target elements selected by the user in this instance is combined into the target primitives selected in this instance, and a new second canvas is created within the DOM tree to accommodate the selected target primitives. By having the user directly trigger the primitive selection operation on the first canvas, the target primitives involved in the target vector graphics can be generated, thus allowing for rapid drawing migration even when the domain primitives do not exist in the graphic configuration software.

[0076] S360. Add the selected target graphic element as a graphic element template to the graphic element template library for storage.

[0077] Specifically, the target graphic element selected by the user in this instance can be added as a new graphic element template to the graphic element template library of the graphic configuration software for storage, so that the graphic element styles in the graphic element template library can be updated in real time.

[0078] S370. Obtain the target graphic area that has not yet been rendered in the target vector graphic.

[0079] The target graphic area can refer to the unrendered graphic area remaining after removing the currently rendered primitive area in the second canvas from the target vector graphic in the first canvas.

[0080] Specifically, the target graphic area that has not yet been rendered will change dynamically with each split rendering of the primitives. Therefore, it is necessary to obtain the target graphic area that has not yet been rendered in the target vector graphic in real time so as to continue to split the primitives of the target graphic area.

[0081] S380. Perform template matching on the target graphic area using the graphic template library to determine the target graphic element that matches the graphic template, and render the matching target graphic element onto the second canvas.

[0082] The target graphic element matching the graphic element template can include graphic elements that are exactly the same as the graphic element template, or it can include similar graphic elements that belong to the same category as the graphic element template. For example, such as Figure 2 As shown, if the primitive template is a diode primitive, the matching target primitives can include resistor primitives and capacitor primitives.

[0083] Specifically, since similar primitives in the target graphic area have different displacements and scaling ratios, the position and size data of the target graphic area and the primitive template can be preprocessed during the first round of template matching. For example, the "points" tag of a polyline is used to indicate the number of points involved in the polyline element, thus allowing matching and filtering of polyline elements with the same number of points. If the primitive template contains multiple polyline elements or combinations of other elements, each element is matched, which is considered a preliminary match. During the first round of template matching, potentially similar areas in the target graphic area can be cropped, and a second round of template matching can be performed on these areas. For example, taking a polyline as an example, it can be determined whether points with the same number of points have the same slope, whether the distance between points is the same or a uniform multiple, and whether this multiple can be carried over to other graphic traversal matches. Through two rounds of template matching, target primitives that match each primitive template in the primitive template library can be quickly identified, and all matching target primitives can be rendered on the second canvas.

[0084] It should be noted that if there are still unrendered target graphic areas in the target vector graphic after template matching, that is, there are still unsplittered target graphic elements, the user can continue to trigger the selection operation, that is, return to step S340 to continue graphic element splitting, and store the latest split target graphic element as a graphic element template, and perform graphic element template matching based on the latest stored graphic element template, until all target graphic elements in the target vector graphic have been split. Thus, graphic element splitting is performed by combining user selection operation and graphic element template matching, which further improves the efficiency of graphic element splitting.

[0085] It should be noted that after step S330, the primitive template matching operation can also be performed first, i.e., steps S370-S380. If there are still unrendered target graphic areas in the target vector graphic after template matching, then the user manually selects primitives operation in S340-S350 is performed again, and the newly selected target primitive is used as a new primitive template for primitive template matching again, until all target primitives in the target vector graphic have been completely split. This embodiment does not limit the execution order of the user selection operation and the primitive template matching method.

[0086] S390. Perform connection processing on each target graphic element on the second canvas to obtain the logic drawing that is migrated to the graphic configuration software.

[0087] The technical solution of this embodiment adds the target graphic element selected by the user as a graphic element template to the graphic element template library for storage. This allows for real-time updates of the graphic element styles in the graphic element template library. Furthermore, it enables template matching based on the target graphic area that has not yet been rendered by the stored graphic element template, automatically extracting other target graphic elements that match the graphic element template. This eliminates the need for the user to select target graphic elements one by one, reducing the number of selections required by the user. Consequently, it further improves the efficiency of drawing migration even when the required domain graphic elements are not available.

[0088] Based on the above technical solution, S380 may include: performing document traversal matching between the template tag document corresponding to the graphic template in the graphic template library and the target graphic document corresponding to the target graphic area by means of tag attribute matching; and rendering the target graphic onto the second canvas based on the target graphic document that matches the template tag document.

[0089] Each time a primitive template is added to the primitive template library, it is essentially a hierarchical XML (Extensible Markup Language) template tag document. For example, the XML tag document portion corresponding to the target element set in the SVG file can be determined as the template tag document of the corresponding primitive template. The target graphic document corresponding to the target graphic region can refer to the remaining document in the second graphic file after removing the document portion corresponding to the rendered target primitive. For example, Table 1 gives an example of a template tag document and the matched target primitive document. Table 2 gives an example of the tag attributes that need to be matched for different graphic elements in an SVG file.

[0090] Table 1 shows examples of template tag documents and matched target meta-documents.

[0091]

[0092] Table 2 shows examples of tag attributes that need to be matched for different graphic elements in an SVG file.

[0093]

[0094] Specifically, by using tag attribute matching, the system can traverse and query the template tag documents corresponding to the graphic template in the target graphic document corresponding to the target graphic area, accurately match the similar parts to determine the target graphic document that belongs to the same category as the graphic template, and parse the target graphic document into the corresponding target graphic and render it onto the second canvas. This allows for the automatic matching and rendering of graphic elements of the same category.

[0095] The following are embodiments of the drawing migration device provided in this invention. This device and the drawing migration methods in the above embodiments belong to the same inventive concept. For details not described in detail in the embodiments of the drawing migration device, please refer to the embodiments of the drawing migration methods described above.

This embodiment is applicable to situations where drawings intended only for display and not for editing are migrated to graphical configuration software, and is particularly applicable to scenarios where CAD drawings are migrated to graphical configuration software. Figure 4 As shown, the device specifically includes: a first graphic file acquisition module 410, a first graphic file conversion module 420, a target vector graphic rendering module 430, a target primitive rendering module 440, and a target primitive connection module 450.

[0098] The technical solution of this embodiment obtains a first graphic file in a first graphic file format corresponding to the drawing to be migrated, and converts the vector graphic elements in the first graphic file according to a second graphic file format to obtain a second graphic file in the second graphic file format.
