Description

Method of Converting SVG Graphics to Visio Graphics

technical field

The invention relates to a file conversion mechanism, in particular to a method for converting SVG graphics into Visio graphics.

Background technique

With the development of various enterprises and companies, more and more jobs require SVG graphics and Visio graphics. This technology focuses on the situation that designers urgently need Visio graphics corresponding to SVG graphics when they only have SVG graphics. The invention can efficiently convert SVG graphics into Visio graphics, and solves the embarrassing situation that there are only SVG graphics but no Visio graphics. In this situation, most enterprises and companies adopt the purely manual method of manually drawing the corresponding Visio graphics according to the SVG graphics, which is time-consuming and labor-intensive, and it is easy to be negligent and inefficient during manual drawing. For this reason, we have invented a new method for converting SVG graphics into Visio graphics, which solves the above technical problems.

In the steps of graphic verification and graphic correction, according to the judgment result of graphic verification, if the information is incomplete, the missing information can be prompted, and the warning will be marked in yellow, and then the relevant information will be automatically supplemented.

In the steps of graphics verification and graphics correction, when the system checks and corrects the graphics and is still incorrect, the system will mark the wrong component graphics in red to display the equipment that needs manual modification. After completion, continue to perform graphics verification.

The method for converting SVG graphics into Visio graphics in the present invention only needs the working designer to specify the conversion directory, and the conversion process is automatically completed by the system. Even if there is a drawing problem in the original drawing, the system can automatically repair it, which greatly facilitates the designer. The work has improved the progress and efficiency of graphic design, saved resources, and avoided some repetitive errors.

Detailed ways

In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

As shown in FIG. 1 , FIG. 1 is a flowchart of a specific embodiment of the method for converting SVG graphics into Visio graphics according to the present invention.

In step 101, a Visio graphics stencil VSS file is created. In this step, the Visio mold is made, the mold graphic style is established according to the engineering requirements, and a Vss file dedicated to Visio graphics is formed. The process goes to step 102.

In step 102, the Tbl file in the SVG graphic file is obtained from the SVG graphic data source according to the specified path of the SVG graphic. The information content of the tbl file includes graphic files and basic mold files, and the system automatically reads appropriate files in the specified disk directory. The process goes to step 103.

In step 103, identify the Tbl file information content in the SVG graphic file to create a graphic structure model and attribute information model, and the system reads the connection information and various attribute information in the SVG graphic file. The flow goes to step 104 .

In step 104, the coordinates of the SVG graphic elements and the Visio stencil VSS file are obtained. Some units and coordinate systems in the SVG graphic are different from Visio. The process goes to step 105.

In step 105, coordinate comparison is performed. According to the coordinates of the SVG graphic element and the Visio mold VSS file, determine the coordinate difference value of the newly generated Visio graphic element and the coordinate difference value of the SVG graphic element, subtract the current coordinate point from the difference value of the coordinate, and get its absolute value , for the Visio graphic element coordinate point, establish the exact coordinates of the Visio graphic element. The flow goes to step 106 .

In step 106, the graph is drawn. According to the data information obtained after the above operations, the system automatically draws graphics and adds connection relations according to the Visio mold file, and adds the required attributes of the equipment according to the original drawing information while drawing the graphics. The process goes to step 107.

In step 107, pattern verification is performed. According to the converted Visio graphics display, judge the connection status of the graphics: whether there are isolated islands, incomplete information, etc. The flow goes to step 108 .

In step 108, the graphic correction is carried out, and according to the judgment result, if the connection is wrong, it is corrected intelligently or manually after recording the error log until it is correct. Specifically, according to the judgment result, if there is an island state, analyze the devices that may be connected according to a certain range, and automatically connect according to the set range value of the device to eliminate the island; if the information is incomplete, the missing information can be prompted, and Mark the warning in yellow, and then automatically supplement the relevant information; if the graphics are normal, go to step 109; when the system checks that the graphics are still incorrect after correction, the system will mark red on the wrong component graphics to display the equipment that needs manual modification. After completion, Continue to check this step.

In step 109, the graphic conversion is normal, a data file is formed, and an XML format data file and a graphic file are formed according to the converted connection information and data information. The flow goes to step 110 .

In step 110, graphic saving is performed. Save the graph to a settings directory or a settings database. The process ends.
