step S101, acquiring a drawing file;
specifically, the drawing file may be a file of various formats such as PDF, DWF, BMP, JPG, TIF, PNG, and the like.
Further, the drawing file source and transmission storage are uploaded to a server or a remote cloud service (including but not limited to original files, authorized files, CAD files, non-CAD files, and disassembled and fused for such files) by means of network transmission, distribution, integration and the like, wherein the variation processing is integrally uploaded to the server or performed on the files. The server obtains the drawing file from the client, so as to further process the drawing file, and the client may be one or more of devices such as a mobile phone, a tablet Computer, a PC (Personal Computer), a notebook Computer, and the like, including but not limited to the above terminals.
Step S102, analyzing a drawing file to obtain basic data in the drawing file;

The basic data at least comprises basic geometric types, coordinates, attribute values, custom geometric types, coordinates, attribute values, and further comprises derived data, split assembly data and the like generated thereby. For example: the circle in the drawing, the corresponding basic data is the information such as the center point, the diameter and the like of the circle; straight lines in the drawing, corresponding basic data are information such as a starting point and an ending point; the corresponding basic data of the artistic words in the drawing is information such as characters, colors, fonts and the like of the artistic words.
Furthermore, the analysis technology relates to the related knowledge of a plurality of subjects such as C/C + + programming technology, file processing, memory management, data structure algorithm, geometry and graphics. Parsing techniques include, but are not limited to, C/C + +, Java, C # #, VB, python, etc. programming techniques, as well as the gist, structure, algorithm, application model, etc. in the subject methods involved. The scope includes the use of the method, phase change packaging, dismantling and the like, including but not limited to autonomous development, third party commercial cooperation, paid services and the like.
Step S103, generating standardized data according to basic data in the drawing file;
specifically, after analyzing the basic data in the graph paper file, processing and converting the basic data to form standardized data, namely, processing and converting the standardized data into universal images and characters which can be recognized by naked eyes; it can also be said that a computer language is converted into a language recognizable to the naked eye. For example: converting the circle center and the diameter information into a circle with a general format; converting the starting point and the ending point into straight lines in a general format; the characters are converted into artistic characters with colors and fonts.
Further, the processing technology and other technologies relate to the related knowledge of multiple subjects such as the C/C + + programming technology, file processing, memory management, data structure algorithm, geometry and graphics. The processing technology includes but is not limited to C/C + +, Java, C # #, VB, python and other programming technologies, and points, structures, algorithms, application models and the like in the covered subject methods.

That is to say, according to the format of the display file supported by the display platform, the server adjusts the format of the standardized data, so that the display can be more quickly and efficiently performed on the real platform. For example: the display platform supports PDF file format, and the resolution is 1280 multiplied by 720; if the original file of the server is in a word file format and the resolution is 1366 × 768, the original file is converted into a PDF file format on the server, and the resolution is 1280 × 720.
Furthermore, according to the obtained standardized data, original paper graphs are displayed in high quality by utilizing the advantages of extreme simplicity, convenience, uniformity, high efficiency, interconnection, one-to-one correspondence and the like according to different devices and platforms and the combination of front-end development technology. Implementations of displays on platforms involving html, css, js, wasm, threejs, python, etc., include but are not limited to methods (method details), frameworks and solutions (solution details) derived therefrom to address this issue, such as: and realizing the application and deployment schemes such as HTML5, CSS3, Wasm, Threejs and the like.

Specifically, when the drawing file is analyzed, the file is analyzed by combining a file coding format and a data storage format on the basis of a binary file, and an autonomous research and development tool or a tool such as commercial cooperation software is adopted. For example: the original file is a DWG format file, data of the DWG file can be selectively obtained by adopting an Open Design Alliance tool set, and the analyzed data is converted into basic data of basic geometric figure elements according to a data bit storage format and a user-defined standard.
In another embodiment, as shown in fig. 2, generating the normalized data from the basic data in the drawing file includes: performing data conversion according to the data type of the basic data and the basic graph in the drawing file to generate standardized data; the normalized data includes at least: standard geometry data and generic data.
Specifically, data classification is performed according to the data type of the basic data, and then basic graphics are collected, so that a standard geometric graphic, namely a universal graphic, is formed, and the universal graphic can be directly converted according to a display format. For example: the data types may include: the map layer comprises a map layer name, colors and the like, and the entity type comprises geometric attributes and the like.
In another embodiment, the display parameters include at least: a display format; adjusting the normalized data according to the display parameters, comprising: the normalized data is adjusted according to the display format.

specifically, when a large amount of basic data exists, a large amount of space is occupied, and meanwhile, conversion efficiency is reduced in the process of processing a large amount of repeated data, so that the scheme is an optimization scheme of the scheme, wherein whether a large amount of repeated data exists in the large amount of data is identified firstly, and then the repeated data is picked out for processing. It is judged whether or not the plurality of pieces of basic data satisfy the multiplexing condition, that is, whether or not the large amount of data is duplicated.
Step S202, if the judgment result is yes, only one basic data in the plurality of basic data is reserved;
specifically, if a large amount of repeated data is determined, only one copy of the same basic data is retained, and the large amount of repeated basic data is deleted, so that the processing efficiency and the space memory are ensured.
In another embodiment, the multiplexing conditions include: the scaling of a plurality of basic data of the same class is different; or the rotation angles of a plurality of basic data of the same class are different; or the position of a plurality of pieces of basic data of the same class is different.
Specifically, the basic data of the large number of repetitions means: more than two basic data of the same type can be different in rotation angle, position and scaling, but the basic data is the same data in nature, and only part of the attributes are modified. For example: two identical triangles, one of which is placed in a positive way and the other of which is placed in a negative way, are considered as repeated basic data; two squares with identical size ratios, one near the header and the other near the footer, are also considered as repetitive base data.
In another embodiment, as shown in fig. 4, includes:

Specifically, it is first identified whether the appearing text is explanatory text or graphic text, the graphic text being used to explain graphics, such as: the graphic characters are characters such as "as shown in fig. 5" and "as circular in fig. 6". The graphic characters and the graphics are displayed together, and the character description characters are not packaged and displayed together with the graphics, so that the complexity of character output is reduced, and the display and the output are high-efficient.
In another embodiment, after identifying the descriptive and graphical text and graphics in the drawing file, the method comprises: outputting and displaying according to the meanings of the descriptive characters and the graphic characters in the drawing file; or outputting and displaying according to the scene of the graph in the drawing file; or outputting and displaying according to the coverage range of the graph in the drawing file.
Specifically, when it is recognized that the meanings of the characters have the same meaning, they may be put together for output, for example: the three paragraphs are all for the description of fig. 1, and then the output can be taken as a whole according to the three paragraphs, which is easier for the reader to understand. Or to identify a scene in the graph, for example: and identifying that triangles appear in the three pictures, selecting the scenes with the triangles, and displaying the scenes independently or making association.
