Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In order to facilitate a clearer understanding of various embodiments of the present application, some relevant background knowledge is first presented as follows.
The OFD document solves the problem of non-uniform document format, so as to conveniently store, read and edit the electronic document.
In the related art, OFD describes graphic elements generally in the form of extensible markup language files (Extensible Markup Language, XML). Specifically, when describing the graphic elements by using an XML mode, the graphic element data of all the OFD files are stored in the XML files in the form of OFD graphic element objects, and the reader renders the graphic data to a reading area by analyzing the XML files during reading.
It should be noted that XML is an extensible markup language, a subset of a standard generic markup language, which can be used to mark data and define data types, and is a source language that allows a user to define his own markup language. The method has the advantages of more data, complex structure, slower analysis speed during display and numerous defects.
The method specifically comprises the following steps:
(1) The file becomes large:
for the multi-graphic element data file, which contains a large number of various graphic elements, graphic labels and the like, when the multi-graphic element data file is converted into an OFD, the graphic element data is converted into an XML complex type mode to describe, the XML complex type is stored in the OFD file, the data volume is huge, and the finally generated OFD file is much larger than the original file. FIG. 1 is a schematic diagram of a multi-graphic element data file provided by the present application; assume that the multi-graphic element data file shown in fig. 1 is a PDF file with a size of 150KB; when the PDF file is converted into an OFD document, the size becomes 250KB.
(2) The storage mode is complex:
in the related art, since the OFD document is described by means of an XML complex type, this is mainly used for a Region (Region) which is composed of a series of branch paths (areas), each of which is closed. The XML mode is used for representing the multi-graphic element data file, so that the conversion process is complex, time is consumed, and the storage mode is complex.
(3) The opening speed is slow:
in the related art, because the OFD document is described in an XML complex type manner, when reading and rendering, the XML document needs to be parsed according to the structure, and then the read character data is converted into binary data, so that the rendering process is quite time-consuming for documents containing a large amount of primitive data such as engineering drawings.
In summary, in order to improve the rendering efficiency of the OFD document, so that a user can quickly open the OFD document containing the multi-graphic-element data, and improve the user experience, the embodiment of the application provides an opening method and device of the open format document, electronic equipment and storage medium.
The method for opening the open layout document provided by the application is specifically described below with reference to fig. 2 to 6. Fig. 2 is one of the flow diagrams of the open layout document opening method provided by the present application, and referring to fig. 2, the method includes steps 201 to 203, where:
step 201, extracting graphic element data and non-graphic element data in an original file.
Firstly, it should be noted that the execution body of the present application may be any electronic device capable of implementing OFD document conversion, for example, any one of a smart phone, a smart watch, a desktop computer, a laptop computer, and the like.
In this embodiment, the format types of the original file are various, for example, a word file, a PDF file, a txt file, etc., and the present application does not limit the format types of the original file. That is, the method for opening the OFD document provided by the application can be suitable for a scene that non-OFD documents such as word and PDF containing multi-graphic element data are converted into OFD documents.
In order to improve the rendering efficiency of the OFD document, so that a user can quickly open the OFD document containing multi-graphic-element data, in the embodiment, firstly, graphic-element data and non-graphic-element data in an original file (such as an engineering drawing) are required to be extracted, and aiming at two different types of data, the application adopts different rendering modes, so that a computer can reduce the processing amount of the data, and the rendering efficiency of the OFD document is improved.
Step 202, converting the graphic element data into a binary file.
In this embodiment, the core idea is to change the storage mode of the graphic element data after converting the original file containing the multi-graphic element data into the OFD document, and reduce the file size, thereby realizing the goal of rapidly opening the OFD document containing the multi-graphic element data.
Specifically, after extracting the graphic element data and the non-graphic element data in the original file, the graphic element data needs to be identified first, and then the graphic element data is converted into a binary file.
In practical applications, there are various ways to convert the graphic element data into a binary file, for example, binary packaging is performed on the graphic element data based on a base64 database in python to generate the binary file; for another example, a pixel value of each pixel of the graphic element data is extracted, and the pixel value is converted into a binary, so that a binary file can be generated. The conversion mode of the binary file is not particularly limited in the present application.
And 203, opening an OFD document corresponding to the original file based on the binary file and the non-graphic element data.
In this embodiment, when rendering is performed based on the binary file and the non-graphic element data, the graphic element data is obtained and rendered by reading the binary file, and compared with the text file in the XML format, the read binary file can be directly put into the memory for use without further processing, thereby greatly shortening the time for rendering the file.
According to the open format document opening method, the graphic element data and the non-graphic element data in the original file are extracted, and then the graphic element data are converted into the binary file, so that the binary file does not need to be further processed by a computer, the graphic element data are rendered based on the binary file, the time for rendering the OFD document is greatly shortened, the OFD document is opened based on the binary file and the non-graphic element data, the rendering efficiency of the OFD document containing the multi-graphic element data is improved, and therefore a user can rapidly open the OFD document containing the multi-graphic element data, and the user experience is improved.
Optionally, the extracting the graphic element data and the non-graphic element data in the original file may be specifically implemented by the following steps [1] -step [ 2):
step [1], obtaining tag information in the original file, wherein the tag information is used for representing the data type of each data in the original file;
and step [2] extracting the graphic element data and the non-graphic element data based on the label information.
In this embodiment, the tag information that is carried in the original file and is used to characterize the data type of each data in the original file, and based on the tag information, the graphic element data and the non-graphic element data in the original file can be determined.
For example, in the original file, the graphic element data each carry tag information [ type1], and the non-graphic element data each carry tag information [ type2], i.e., in the original file [ type1] represents the graphic element data, and [ type2] represents the non-graphic element data.
For another example, in the original file, the graphic element data each carry tag information [ a ], and the non-graphic element data each carry tag information [ b ], i.e., in the original file [ a ] represents the graphic element data, and [ b ] represents the non-graphic element data.
In the embodiment, the graphic element data and the non-graphic element data in the original file can be extracted based on the label information, and different rendering modes are adopted for two different types of data, so that the processing amount of the graphic element data can be reduced by a computer, and the rendering efficiency of the OFD document is improved.
Optionally, the following steps are further required to be performed after the converting the graphic element data into the binary file:
and storing the binary file into an attachment folder in the OFD document structure.
In this embodiment, the graphic element data needs to be converted into a binary file. That is, each graphic of points, lines, rectangles, circles, and the like in the graphic element data is defined as a structure. When the OFD file is generated, the graphic element data is stored in a binary file with the corresponding structure.
At this time, the binary file is added to the OFD file in the form of an attachment. This way of storage can greatly reduce the amount of data and thus the file size. In addition, the data in the memory for calculation is stored in a binary format, so that the data is stored in the file more quickly by using the binary format.
It should be noted that the file name of the binary file is related to the page number of the graphic element data in the original file.
For example, the file of the binary file corresponding to the graphic element data a is named as "page0.Bin", which means that the graphic element data a is located on page0 of the original file;
the file of the binary file corresponding to the graphic element data B is named "page1.Bin", indicating that the graphic element data B is located on page1 of the original file.
In practical application, the binary file is named as xxx. Bin, and stored in an attachment form to an attachment folder in an OFD document structure, and a corresponding attachment. Xml file is generated.
Alternatively, the attributes. Xml file may be represented by:
<?xml version=“1.0” encoding=“utf-8”?>
<ofd:Attachment xmlns:ofd=“http：//www.ofdspec.org/2016”>
<ofd:Attachment ID=“38” Name=“page0.bin” Format=“bin”
CreationDate=“2023/3/27 11:14:52” ModDate=“2023/3/27
14:31:54” Size=“150807” Visible=“true” Usage=“none”>
<ofd:FileLoc>
Attachs/e0bdb62f00d94ebe926e74f2ef797elc.bin
</ofd:FileLoc>
</ofd:Attachment>
</ofd:Attachment ID=“40” Name=“page1.bin” Format=“bin”>
CreationDate=“2023/4/3 15:27:56” ModDate=“2023/4/3
16:02:25” Size=“73216” Visible=“true” Usage=“none”>
<ofd:FileLoc>
Attachs/65b9bf6fcbfe43cfab34c78754e98350.bin
</ofd:FileLoc>
</ofd:Attachment>
</ofd:Attachments>
in the above embodiment, by storing the binary file in the form of an attachment in the attachment folder of the OFD file, this storage manner can greatly reduce the data amount of the graphic element data, thereby reducing the file size. The file size is reduced, so that the efficiency of processing data by the computer can be improved.
Optionally, the binary file includes binary data corresponding to the graphic element data and page position information; the OFD document includes a graphic element portion and a non-graphic element portion.
Specifically, page position information, that is, file naming of binary files corresponding to the graphic element data mentioned above, based on the file naming, the position of the graphic element data in the original file can be determined.
The opening of the OFD document corresponding to the original file based on the binary file and the non-graphic element data may be specifically realized by the following steps [1] to [3 ]:
step [1], rendering the graphic element part based on the binary data and the page position information.
In practical application, in the process of performing OFD document conversion on an original file, it is first required to check whether a binary file named as "xxx.bin" is contained in an Attachs folder, if so, the "xxx.bin" binary file is read, and the graphic element data is rendered to a corresponding page position according to page position information (i.e. related page number of the graphic element data in the original file) in the file naming.
And step [2], rendering the non-graphic element part based on the non-graphic element data.
Specifically, other data (i.e., non-graphic element data) except the graphic element data needs to be rendered according to the standard conversion mode of the OFD document to generate a non-graphic element part.
And step [3] opening the OFD document based on the graphic element part and the non-graphic element part.
In the above embodiment, based on the binary data and the page position information, the graphic element portion is rendered, and then based on the non-graphic element data, the non-graphic element portion is rendered, thereby realizing quick open browsing of the OFD document containing the multi-graphic element data.
Optionally, the rendering the non-graphic element part based on the non-graphic element data may be specifically implemented by the following steps [1] -step [ 2):
step [1], convert the said non-graphic element data into the extensible markup language file;
and step [2], rendering the non-graphic element part based on the extensible markup language file.
In this embodiment, when rendering the non-graphic element data, the data structure of the non-graphic element data needs to be parsed, converted into an XML file, and then converted into binary data, thereby rendering the non-graphic element portion of the OFD document.
In the embodiment, different rendering modes are adopted for two different types of data, so that the processing amount of the graphic element data can be reduced by a computer, the rendering efficiency of the OFD document is improved, and the OFD document containing the multi-graphic element data can be opened quickly.
