Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Fig. 1 is a flowchart of a drawing migration method according to an embodiment of the present invention, where the embodiment is applicable to a case of migrating a drawing which is only used for presentation but cannot be edited into graphic configuration software, and in particular, to a case of migrating a CAD drawing into the graphic configuration software. The method can be executed by a drawing migration device, and the device can be realized by software and/or hardware and is integrated in electronic equipment. As shown in fig. 1, the method specifically includes the following steps:

s110, acquiring a first graphic file in a first graphic file format corresponding to a drawing to be migrated.

The drawing to be migrated refers to a drawing which needs to be migrated to graphic configuration software and is only used for displaying but cannot be edited. For example, the drawing to be migrated may refer to a CAD drawing created based on CAD drawing software. The drawing to be migrated contains the generated vector graphics. The first graphic file format may refer to a file storage format of vector graphics in a drawing to be migrated. Vector graphics in the first graphics file format cannot be identified in the graphics configuration software. For example, the first graphic file format may refer to a drawing exchange file DXF (Drawing Exchange Format) format corresponding to a CAD drawing, and the corresponding first graphic file may refer to a DXF file corresponding to the CAD drawing. The DXF format is stored in ASCII code format and can be read and edited by a notepad. Correspondingly, the DXF file is a markup file representing graphics stored in ASCII code format and editable by notepad reading.

Specifically, drawing a drawing to be migrated including a vector graphic, such as a CAD drawing, by using drawing software, and importing a first graphic file under a first graphic file format, such as a DXF file corresponding to the CAD drawing, into graphic configuration software so as to perform drawing conversion in the graphic configuration software based on the DXF file, thereby obtaining a logic drawing with a logic connection relationship.

S120, converting the format of the vector graphic elements in the first graphic file based on the second graphic file format to obtain a second graphic file in the second graphic file format.

The second graphic file format may refer to a file storage format in which vector graphics can be identified in graphic configuration software. For example, the second graphics file format may refer to the scalable vector graphics SVG (Scalable Vector Graphics) format. The vector graphic element may be an element object for composing a vector graphic. For example, vector graphics elements may include, but are not limited to: straight lines, line segments, circles, ellipses, circular arcs and spline curves. In different graphic file formats, the representation modes corresponding to the same vector graphic element are different. For example, the same vector graphic element is characterized by different element names, for example, the element name corresponding to the vector graphic element "straight line" in DXF format is: the element names corresponding to the vector graphic element 'straight LINE' in the LINE and SVG formats are as follows: line. The coordinate systems corresponding to the different graphic file formats are also different, so that the element coordinate values of each vector graphic element also need to be converted. For example, the origin of the coordinate system in the DXF format is in the lower left corner of the screen, the X-axis is forward to the right, and the Y-axis is forward to the top. The origin of the coordinate system in the SVG format is in the upper left corner of the screen, the positive direction of the X-axis is to the right, and the positive direction of the Y-axis is to the bottom.

Specifically, the first graphic file in the first graphic file format may be converted into the second graphic file in the second graphic file format based on the original format conversion tool. The vector graphic elements in the first graphic file can also be subjected to name conversion and coordinate conversion based on the element conversion relation between the second graphic file format and the first graphic file format, so as to obtain a second graphic file in the second graphic file format.

Illustratively, S120 may include: converting the element names of the vector graphic elements in the first graphic file based on the corresponding relation between the vector graphic element names in the first graphic file format and the vector graphic element names in the second graphic file format; converting element coordinate values of vector graphic elements in the first graphic file based on a first graphic coordinate system corresponding to the first graphic file format and a second graphic coordinate system corresponding to the second graphic file format; and determining the graphic file obtained after the conversion of the element name and the element coordinate value as a second graphic file in a second graphic file format.

Specifically, 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, the element name of each vector graphic element in the first graphic file is converted into the vector graphic element name in the corresponding second graphic format, so that conversion and translation of the element names are realized. Based on a first graphic coordinate system corresponding to the first graphic file format and a second graphic coordinate system corresponding to the second graphic file format, a coordinate transformation matrix can be determined, and based on the coordinate transformation matrix, conversion of element coordinate values is performed on each vector graphic element in the first graphic file, element coordinate values under the second graphic coordinate system are obtained, so that conversion of the coordinate system of the element coordinate values is realized. After the conversion of the element names and the element coordinate values is completed, the obtained graphic file can be determined to be a second graphic file in a second graphic file format, so that the vector graphic is converted and translated from the drawing in the first graphic file format to the drawing in the second graphic file format, for example, the vector graphic is converted and translated from the CAD drawing to the SVG drawing.

It should be noted that the second graphic file obtained after conversion is only a collection of a pile of elements, and the element combinations are not yet mapped to specific device primitives. For example, the SVG file obtained after conversion is as follows:

<defs>

</clipPath>

</defs>

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

s130, analyzing the second graphic file, and rendering the analyzed target vector graphic to the first canvas.

The target vector graphic may refer to a vector graphic that needs to be migrated. The canvas may be a drawing for showing graphics. For example, the Canvas may be, but is not limited to, a Canvas. The first canvas may be a drawing for exposing a target vector graphic of the primitive to be sliced in order to allow subsequent edit extraction operations.

In particular, since the second graphics file format (such as SVG format) does not provide pixel-level processing, picture pixel data of a specific location cannot be acquired. In order to segment the primitives in the second graphic file, the second graphic file may be parsed into Javascript drawing codes corresponding to the target vector graphic through a Canvas plugin, such as a fabric. Js tool, and the target vector graphic may be rendered onto a first Canvas, such as a first Canvas, by executing the Javascript drawing codes. For example, fig. 2 shows an example of a drawing migration process, and as shown in fig. 2, a target vector graphic in a drawing to be migrated is rendered on a first canvas, so that a user can perform a primitive selection operation on the first canvas.

And S140, determining a target primitive corresponding to the target vector graphic based on user selection operation and/or primitive template matching mode triggered on the first canvas, and rendering the target primitive onto the second canvas.

Wherein, the graphic element may refer to a configuration element for characterizing the device graphic. It should be noted that the primitive may be closed or non-closed, such as a pin line with two ends. For example, the resistor graphic element may construct a graph of resistors in a "straight line + rectangle + straight line" manner. The target primitive may refer to a primitive contained in the target vector graphic. The target vector graphic includes a plurality of target primitives. The second canvas may be a drawing for showing the cut target primitives.

Specifically, all target primitives in the target vector graphics can be obtained through user selection operation triggered by a user on the first canvas and/or through splitting in a primitive template matching mode. For example, if the primitive template library does not have primitives in the drawing field to be migrated, the user may perform a primitive selection operation on the target vector graphic displayed by the first canvas based on the service requirement, for example, the user may perform a click operation or a circle selection operation on the graphic portion belonging to the same primitive, so that the target element set selected by the user each time may be combined into a corresponding target primitive. For example, as shown in fig. 2, the user performs circle selection on the diode part in the circuit on the first canvas, such as the dashed box in fig. 2, so that the user's circle selected part can determine a target primitive, namely the diode primitive, so that the user can directly trigger and select each primitive on the first canvas, split all the target primitives in the target vector graphic, and further allow drawing migration to be performed quickly on the premise that no domain primitive exists in the graphic configuration software.

For another example, if the primitive template library has primitives in the drawing field to be migrated, template matching can be performed on the primitive templates in the primitive template library and the target vector graphics on the first canvas, so that the target primitives in the target vector graphics can be automatically matched without manually drawing the target primitives.

Furthermore, all target primitives in the target vector graphics can be split by combining user selection operation and primitive template matching mode. For example, after a user selects a target primitive on the first canvas, the target primitive selected by the user can be used as a primitive template to be matched with the target vector graphic, and other target primitives in the target vector graphic can be automatically matched, so that the number of times of selecting the primitive by the user can be reduced, and the primitive splitting efficiency is improved. For example, as shown in fig. 2, a diode primitive selected by a user is used as a primitive template to perform template matching, so as to obtain a matched resistor primitive and capacitor primitive.

The present embodiment may create a new second Canvas, such as a second Canvas, within the DOM (Document Object Model ) tree to accept the split target primitives. The splitting condition of the user can be prompted by rendering the split target primitives to the second canvas for display. According to the embodiment, corresponding target graphic elements can be rendered according to the original graphic positions in the imported drawing, and the target graphic elements are displayed at the same positions, so that subsequent connection operation is simplified, and drawing migration efficiency is further improved.

And S150, carrying out connection processing on each target graphic primitive on the second canvas to obtain a logic drawing migrated to the graphic configuration software.

The graphic configuration software may be, but is not limited to, visual graphic rendering software based on web pages. The logic drawing may refer to a drawing with a graphic element logic connection relationship, that is, a visual drawing drawn in graphic configuration software.

Specifically, after all target primitives in the target vector graphics are split, on the second canvas, all the target primitives which are successfully split can be subjected to connection line filling according to the connection relation between the original graphics positions, so that a drawing to be migrated, which is imported into the graphic configuration software, is updated into a logic drawing with the primitive logic connection relation, and drawing migration operation is completed. Through format conversion and user selection operation on the primitives, the drawings in the original working field can be quickly migrated to the graphic configuration software with changed technology, the dependence on the starting of the primitives in the field is reduced, the work consumption of construction from the beginning is reduced, and the drawing migration efficiency is improved.

According to the technical scheme, a first graphic file in a first graphic file format corresponding to a drawing to be migrated is obtained, format conversion is conducted on vector graphic elements in the first graphic file based on a second graphic file format, a second graphic file in the second graphic file format is obtained, the second graphic file is analyzed, and the analyzed target vector graphic is rendered on a first canvas; and determining target graphic primitives corresponding to the target vector graphics based on user selection operation and/or graphic primitive template matching modes triggered on the first canvas, rendering the target graphic primitives to the second canvas, and carrying out connection processing on all the target graphic primitives on the second canvas to obtain a logic drawing migrated to graphic configuration software, so that the vector graphics in the drawing to be migrated can be subjected to graphic primitive splitting without manual redrawing through the user selection operation and/or graphic primitive template matching modes, thereby simplifying drawing migration operation and improving drawing migration efficiency.

Based on the above technical solution, after S140, the method may further include: displaying the primitive confirmation information corresponding to the target primitive after each rendering; and deleting the target primitive which is confirmed to be wrong by the user in response to a primitive error instruction triggered by the user based on the primitive confirmation information.

The primitive confirmation information may be information for prompting the user whether the target primitive rendered at the present time is the primitive to be split. The primitive error instruction may be an instruction to characterize that the current rendered target primitive is not the primitive that needs to be split.

Specifically, after each rendering of the target primitive on the second canvas, corresponding primitive confirmation information may be displayed to prompt the user to perform primitive confirmation. The user can trigger the primitive error instruction by clicking the error button aiming at the displayed primitive confirmation information, and if the primitive error instruction is detected, the target primitive confirmed to be in error by the user can be deleted from the second canvas so as to re-split the primitive. The user may also trigger primitive correct instructions by clicking on the correct button to continue to present the user confirmation of the correct target primitive on the second canvas. When all target primitives in the target vector graphics are split and split is confirmed to be correct, connection processing can be carried out on all the confirmed correct target primitives on the second canvas, so that accuracy of drawing migration can be guaranteed.

Fig. 3 is a flowchart of another drawing migration method according to an embodiment of the present invention, where a process of determining a target primitive through a user selection operation is described based on the above embodiments, and a process of determining a target primitive through a primitive template matching manner is also described based on the above embodiments. Wherein the explanation of the same or corresponding terms as those of the above embodiments is not repeated herein.

Referring to fig. 3, another drawing migration method provided in this embodiment specifically includes the following steps:

s310, acquiring a first graphic file in a first graphic file format corresponding to a drawing to be migrated.

S320, converting the format of the vector graphic elements in the first graphic file based on the second graphic file format to obtain a second graphic file in the second graphic file format.

S330, analyzing the second graphic file, and rendering the analyzed target vector graphic to the first canvas.

S340, determining a target element set selected by the current user in the target vector graph based on the current triggered user selection operation on the first canvas.

Specifically, the user may perform a primitive selection operation on the target vector graphic displayed on the first canvas based on the service requirement, for example, the user may perform a click operation or a circle selection operation on the graphic portion belonging to the same primitive. And monitoring a mouse event, such as a mouse click start event mouseup, a mouse click end event mousedown and a mouse click movement event mousemove, on the first canvas, so that a graphic area clicked or circled by the current user can be determined through the monitored mouse event, and all elements in the graphic area are determined to be a target element set selected by the current user.

And S350, combining the target element sets to determine the target element sets as the target elements selected at the present time, and rendering the target elements selected at the present time onto the second canvas.

Specifically, the target element set selected by the current user is combined into the current selected target element, and a new second canvas is established in the DOM tree to accept the current selected target element. The user directly triggers the primitive selection operation on the first canvas, and the target primitive related in the target vector graph can be generated, so that drawing migration is allowed to be rapidly carried out on the premise that the field primitive does not exist in the graph configuration software.

S360, adding the currently selected target primitive as a primitive template into a primitive template library for storage.

Specifically, the target primitive selected by the user at present can be used as a new primitive template to be added into a primitive template library of the graphic configuration software for storage, so as to update the primitive style in the primitive template library in real time.

S370, acquiring a target graphic area which is not rendered currently in the target vector graphic.

The target graphic region may refer to a graphics region which is not rendered and remains after the target vector graphic in the first canvas removes the primitive region which is currently rendered in the second canvas.

Specifically, the target graphics area which is not rendered at present dynamically changes along with each splitting rendering of the graphics primitive, so that the target graphics area which is not rendered at present in the target vector graphics needs to be acquired in real time, so as to continue splitting the graphics primitive of the target graphics area.

And S380, performing template matching on the primitive templates in the primitive template library in a target primitive region, determining target primitives matched with the primitive templates, and rendering the matched target primitives on a second canvas.

The target primitive matched with the primitive template can comprise the primitive identical to the primitive template, and can also comprise similar primitives belonging to the same class with the primitive template. For example, as shown in FIG. 2, if the primitive templates are diode primitives, the matching target primitives may include resistor primitives and capacitor primitives.

Specifically, because similar primitives in the target graphic region have different displacements and different scaling, when the templates of the first round are matched, the position and size data of the target graphic region and the primitive templates can be preprocessed. For example, the points tag of the polyline is used to represent the points involved in the polyline element, so that polyline elements with the same points can be matched and screened out. If the primitive template contains a plurality of polyline elements or other element combinations, each element is matched and then is regarded as preliminary matching. In the first round of template matching, a partial region which is possibly similar in the target image region can be cut out, and the second round of template matching is continued on the partial region. For example, taking polyline as an example, it is determined whether the slope of the same number of points is the same from point to point, whether the distance between points is the same or a uniform multiple, and the multiple may continue in other graph traversal matches. Target primitives matched with each primitive template in the primitive template library can be rapidly determined through two rounds of template matching, and all matched target primitives are rendered on the second canvas.

It should be noted that, if the target graphics area still exists in the target vector graphics after the template matching, that is, there is still a target graphics area still not yet split, the user may continue to trigger the selection operation, that is, return to the mode of step S340 to continue to split the graphics primitive, store the latest split target graphics primitive as the graphics primitive template, and perform the graphics primitive template matching based on the latest stored graphics primitive template until all the target graphics primitives in the target vector graphics have been split, thereby performing the graphics primitive splitting by combining the user selection operation and the graphics primitive template matching mode, and further improving the graphics primitive splitting efficiency.

It should be noted that, after step S330, the primitive template matching operation may be performed first, i.e. steps S370-S380, if the target graphics area still exists in the target vector graphics after the template matching, then the operations of manually selecting the primitive by the user of S340-S350 are performed again, and the newly selected target primitive is used as the new primitive template to perform the primitive template matching again until all the target primitives in the target vector graphics have been split. The embodiment does not limit the sequence of the user selection operation and the primitive template matching mode.

S390, carrying out connection processing on each target graphic primitive on the second canvas to obtain a logic drawing migrated to the graphic configuration software.

According to the technical scheme, the target graphic elements selected by the user at present are used as graphic element templates and added into the graphic element template library for storage, so that graphic element patterns in the graphic element template library can be updated in real time, template matching can be performed on the basis of the target graphic areas which are not rendered currently by the stored graphic element templates, other target graphic elements matched with the graphic element templates are automatically split, the user does not need to select the target graphic elements one by one, the selection times of the user are reduced, and further drawing migration efficiency is further improved on the premise that the field graphic elements are not allowed.

Based on the above technical solution, S380 may include: performing document traversal matching on a template tag document corresponding to a primitive template in a primitive template library and a target graphic document corresponding to a target graphic region in a tag attribute matching mode; and rendering the target primitive onto a second canvas based on the target primitive document matched with the template tag document.

Wherein each primitive template added to the primitive template library is essentially an XML (Extensible Markup Language ) template tag document without hierarchy. For example, the XML tag document portion corresponding to the target element set in the SVG file may be determined as the template tag document of the corresponding primitive template. The target graphic document corresponding to the target graphic region may refer to a remaining document of the second graphic file from which the document portion corresponding to the rendered target graphic element is removed. For example, table 1 gives an example of a template tag document and a matched target primitive document. Table 2 gives an example of tag attributes that different graphic elements in an SVG file need to match.

Table 1 examples of template tag documents and matched target primitive documents

Table 2 example of tag attributes in SVG files that different graphic elements need to match

Specifically, through a label attribute matching mode, traversing and inquiring similar parts of a template label document corresponding to the primitive template in a target graphic document corresponding to the target graphic region, carrying out accurate matching on the similar parts to determine target primitive documents which belong to the same kind as the primitive template, analyzing the target primitive documents into corresponding target primitives, and rendering the corresponding target primitives onto a second canvas, so that the same kind of primitives can be automatically matched, rendered and displayed.
