Detailed Description
Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Currently, the operation modes of electronic documents mainly include two kinds. One is to open and perform operations such as browsing or editing by using a local client, and the other is to open and perform operations such as browsing or editing online, namely, a web operation mode. It will be appreciated that if the electronic document is opened by means of a local client, the local client can effectively recognize the electronic document in a different data format even though the graphic data in the same type of electronic document may have a different data format, so as to correctly display the data in the electronic document, including text data, graphic data, and the like. However, when an electronic document is opened in an online manner, that is, when an electronic document in web form is opened, if graphic data of different data formats are included in the same type of electronic document, a graphic display error problem occurs.
Illustratively, ppt and pptx belong to two disparate format standards of MSPowerPoint, and are different in organization from the definition of document elements to the data. The ppt data format is binary data format, and is the default storage format of PowerPoint95, powerPoint97 and PowerPoint 2003. pptx is OOXML (Office Open XML) standard data format, which is a new data format published with PowerPoint 2007 and is also the default save format after PowerPoint 2007. In both data formats, there are also two different definition methods for the graphical object. Currently, online PowerPoint does not have an efficient solution to deal with the differences in the two formats for electronic documents, which can result in incorrect display of graphics data in the document. For example, when an electronic document in pptx format is opened by online PowerPoint, if there is a custom heart graphic in the electronic document, the online PowerPoint may appear to be unable to recognize the graphic or display the heart graphic as another graphic converted by default by the system, or the like. Thus, how to handle multi-format differences more effectively for web-form electronic documents is a very prominent issue in online electronic document solutions.
In one example, fig. 1 is a flowchart of a graphics processing method according to an embodiment of the present application, where the method may be implemented by a graphics processing apparatus, and the apparatus may be implemented by software and/or hardware, and may be generally integrated in an electronic device, where the graphics processing method is applicable to converting graphics with different data formats in the same type of electronic document into graphics with a uniform data format. The electronic device may be a computer device or various terminal devices, etc. Accordingly, as shown in fig. 1, the method includes the following operations:
s110, obtaining the graphic data to be processed in the document to be processed.
Wherein the document to be processed may be any type of electronic document in web form. The graphic data to be processed may be graphic data included in the document to be processed, which is required to be displayed on line.
In the embodiment of the application, the graphic data to be processed, which is included in the document to be processed, can be uniformly converted by the universal graphic element conversion system. Fig. 2 is a schematic structural diagram of a general graphic element conversion system according to an embodiment of the present application. In one specific example, as shown in FIG. 2, a universal graphic element conversion system may include a multi-format parser, a graphic object converter, and a unified format output engine. Wherein, the multi-format parser and the graphic object converter are in communication connection, and the graphic object converter and the unified format output engine are in communication connection. The multi-format parser, the graphic object converter and the unified format output engine cooperate with each other to perform unified processing and output on graphic data included in the electronic document.
The universal graphic element conversion system can be used with an online electronic document application to convert image data in an electronic document currently being processed by the online electronic document. Accordingly, if the universal graphic element conversion system detects that the online electronic document is opened, that is, detects a web-form to-be-processed document, the to-be-processed graphic data included in the to-be-processed document can be acquired through the multi-format parser.
S120, converting the graphic data to be processed into graphic data with a uniform format; the unified format graphics data is different from the data format of the graphics data to be processed.
Wherein the unified format graphic data may be graphic data having a unified data format and may support web display.
Correspondingly, after the graphic data to be processed in the document to be processed is obtained through the multi-format analyzer, the graphic data to be processed can be analyzed and stored by utilizing a self-defined data format organization architecture in the multi-format analyzer, and the graphic data to be processed is converted into a uniform data format and stored in a memory structure, so that node data and attribute data in the graphic data to be processed are reorganized by utilizing the uniform data format. That is, the multi-format parser may redefine the new data format as a unified data format to reorganize and sort the graphics data to be processed. Further, the graphic object converter may convert graphic data having a uniform data format into uniform format graphic data using graphic data stored in the memory structure. That is, the general graphic element conversion system may parse and save basic data of graphic data to be processed using a multi-format parser, and finally convert the saved graphic data into unified-format graphic data using a graphic object converter.
It follows that the generic graphic element conversion system can be utilized to convert graphic data to be processed into uniform format graphic data having a uniform data format, regardless of the data format. Optionally, the data format of the unified format graphics data may be, for example, JSON (JavaScript Object Notation ) or other formats, so long as the graphics data can be displayed online, and the embodiment of the present application does not limit the specific type of the data format of the unified format graphics data.
S130, outputting the uniform format graphic data by adopting a uniform data output format.
Wherein the unified data output format may be a graphic data output format redefined for unified format graphic data.
Accordingly, after the unified format graphic data corresponding to the graphic data to be processed is obtained, the unified format graphic data can be output by utilizing the unified format output engine, so that the graphic data to be processed with different data formats can finally output the same data format. For example, a unified data output format may be designed based on JSON, such that the graphics data to be processed in each type of document to be processed is ultimately output in JSON format. The JSON format is used for uniformly outputting the uniform format graphic data, so that not only can the basic elements of all the shape data in the graphic be defined, but also the subsequent expansion and upgrading are facilitated, and the expandability of the universal graphic element conversion system is improved.
It should be noted that, the graphics data to be processed according to the embodiments of the present application may include two types of graphics data, one is predefined graphics data, that is, the graphics to be processed is default graphics such as rectangle, triangle, arrow, etc. that are set by default in the document. The other is custom graphic data, such as graphics that can be custom set, such as free curves and polygons.
Therefore, the to-be-processed graphic data in the to-be-processed document is converted into the uniform-format graphic data with the uniform data format by utilizing the universal graphic element conversion system, and the uniform-format graphic data with the uniform data format is output by utilizing the uniform data output format, so that the to-be-processed graphic data with various data formats can be in the uniform data format supporting normal web display, and the web display is not performed by the original data format, thereby solving the problem that the to-be-processed graphic data with different data formats cannot be displayed normally on line, realizing the data processing process of graphic conversion processing, enabling the graphic data with different data formats to achieve the uniform graphic display effect, and effectively improving the convenience of the on-line application of the electronic document.
According to the embodiment of the application, the to-be-processed graphic data in the to-be-processed document is converted into the uniform format graphic data, and the uniform format graphic data obtained by conversion is output by adopting the uniform data output format, so that the problem that the graphic data processing process of different data formats is complex when the existing electronic document is applied online can be solved, the consistent graphic display effect of the graphic data in different data formats can be achieved, and the convenience of the electronic document on-line application is improved.
In an example, fig. 3 is a flowchart of a graphics processing method provided by an embodiment of the present application, where optimization and improvement are performed on the basis of the technical solutions of the foregoing embodiments, and various specific alternative implementations for obtaining graphics data to be processed in a document to be processed and converting the graphics data to be processed into graphics data in a uniform format are provided.
A method of graphics processing as shown in fig. 3, comprising:
s210, obtaining the graphic data to be processed in the document to be processed.
In an alternative embodiment of the present application, the document to be processed includes a first document to be processed and/or a second document to be processed; the graphics data to be processed comprise first graphics data to be processed and/or second graphics data to be processed, and the data formats of the first graphics data to be processed and the second graphics data to be processed are different.
Wherein the first document to be processed and the second document to be processed may be electronic documents having different data formats. The first document to be processed may include first graphic data to be processed therein, and the second document to be processed may include second graphic data to be processed therein. Since the data formats of the first document to be processed and the second document to be processed are different, the data formats of the first graphic data to be processed and the second graphic data to be processed are also different.
It should be noted that, the first document to be processed and the second document to be processed are both electronic documents of the same type, for example, are both Word documents or are both presentation documents. Because different types of electronic documents may have a plurality of corresponding different data formats, the documents to be processed may be further expanded according to the document type data, for example, a third document to be processed, a fourth document to be processed, and the like may be further included. Similarly, the to-be-processed graphic data corresponding to the third to-be-processed document is the third to-be-processed graphic data, and the to-be-processed graphic data corresponding to the fourth to-be-processed document is the fourth to-be-processed graphic data. The embodiment of the application does not limit the document type of the document to be processed and the graphic data type of the corresponding graphic data to be processed. It will be appreciated that the data formats of the graphics data to be processed of the unknown type are different from each other.
In an optional embodiment of the present application, if the document to be processed is a first document to be processed, the first document to be processed is a first type presentation document, and the data format of the graphic data to be processed is a binary format; acquiring the graphics data to be processed in the document to be processed may include the operations of: reading a top container in a document stream from a first document to be processed; acquiring a file list included in the top-level container; reading a file container according to the file list; reading a picture container according to a first parameter variable in the file container when the first parameter variable has a variable value; reading a graphic element container according to a second parameter variable in the picture container; and reading the graphic element container to acquire first graphic data to be processed.
In an alternative embodiment of the present application, the first graphic data to be processed in the first document to be processed is determined to be empty in case there is no variable value for the first parameter variable in the file container.
The document type of the first type of presentation document can be in a ppt format, and the data format of the graphics data to be processed in the ppt format of the document to be processed is a binary format. The file list may be a slide list and the file container may be a slide container. The first parameter variable may be a related variable in the slide container for representing the graphics data. The second parameter variable may be a related variable in the graphic element container for representing the shape data.
It should be noted that all file data in ppt binary format exists in one or more streams, and most of the data is stored in PowerPointDocument (document stream) streams. The content stored in the presentation document in ppt format is based on Record, which in turn includes both Container Record and Atom Record. A single shape is defined in OfficeArtSpContainer (shape data container) records whose shapeProp attribute is one OfficeArtFSP (type and base attribute) record. The RECINSTANCE field of the head OfficeArtRecordHeader (head) of OfficeArtFSP identifies the MSOSPT (shape type) enumeration value of the shape type. Other attributes are recorded in OfficeArtFOPT (attribute list) and OfficeArtTertiaryFOPT (attribute list). In addition, officeArtSpContainer include other data records, such as text and hyperlinks.
Thus, if the document to be processed is a first type presentation document, the graphics data to be processed may be acquired in a storage format of the presentation document in ppt format for the graphics data. Fig. 4 is a schematic flow chart of obtaining graphics data to be processed in a document to be processed according to an embodiment of the present application. In a specific example, as shown in fig. 4, the top container (DocumentContainer) in PowerPoint Document may be read from the first document to be processed, and all slide lists (SLIDELIST) may be further acquired, including the master slide, the layout slide, the slides, and the like, so that the slide (SlideListWithTextContainer) list is read as the file list. After the SlideListWithTextContainer list is obtained, the slide container (SlideContainer) is read based on the slide offset record (SlidePersistAtom) recorded at SlideListWithTextContainer. A determination is made as to whether the variable value exists for the drawing variable (first parameter variable) in SlideContainer. Reading a drawing container (DrawingContainer) according to the drawing variable if the variable value exists in the drawing variable; otherwise, the first type demonstration document does not include graphic data, and subsequent reading and analyzing operations are not needed, so that the reading operation of the graphic data is simplified, and meaningless data analyzing processes are avoided. Correspondingly, if there is a variable value for the drawing variable, then after reading DrawingContainer, the graphic element container is read (OfficeArtDgContainer) according to the OfficeArtDg variable (second parameter variable) in DrawingContainer. Since the related data of the graphic is recorded in OfficeArtDgContainer, officeArtDgContainer can be read to acquire the first graphic data to be processed.
In an alternative embodiment of the present application, the reading the graphic element container may include: reading a shape data container according to a third parameter variable in the graphic element container; and acquiring the graph shape type and the graph attribute data of the graph data to be processed according to the shape data container.
Wherein the third parameter variable may be a related variable in the graphic element container for representing the graphic data.
Further, the specific flow of reading the graphic element container may be: the shape data container (OfficeArtSpContainer) is read from the shape variable (third parameter variable) value in OfficeArtDgContainer. Wherein OfficeArtSpContainer stores mainly three types of graphics data, officeArtFSP records the types and basic attributes of graphics shapes, and OfficeArtFOPT and OfficeArtTertiaryFOPT records other attributes of graphics.
Thus, the first graphic data to be processed can be obtained comprehensively according to the storage format of the presentation document in the ppt format and the graphic data such as the type and the attribute of the first graphic data to be processed.
In an optional embodiment of the present application, if the document to be processed is a second document to be processed, the second document to be processed is a second type presentation document, and the data format of the second graphic data to be processed is an OOXML standard data format; acquiring the graphics data to be processed in the document to be processed may include the operations of: the following operations may be included: carrying out document analysis on the second document to be processed to obtain an analysis file; determining file style dependency relations among the target analysis files according to the dependency relation files of the analysis files; determining a graph searching sequence according to the file style dependency relationship; and searching the graphic data of the target analysis file according to the graphic search sequence to obtain second graphic data to be processed.
The analysis file may be a file obtained by analyzing the second document to be processed. The target resolution file may be a file for acquiring graphic data among the resolution files. The graphic search order may be a default setting in the general graphic element conversion system for searching for the second graphic data to be processed included in the second document to be processed. The file style dependencies may be dependencies between different types of target parsed files.
Note that the pptx format presentation document is a zip package and a complete document is composed of a plurality of XML (eXtensible Markup Language ) files. Fig. 5 is an effect schematic diagram of a storage mode of graphic data in pptx presentation documents according to an embodiment of the present application. In a specific example, as shown in fig. 5, a file directory structure of pptx is shown after the decompression of the file, and graphic data in pptx is stored in a slider xml file under the slider directory. The main content of a slide, such as text, tables, pictures and graphics, is stored in this file. Correspondingly, the data definition of the graph in the document is set by slides- > cSld- > spTree- > sp. Wherein the predefined graph is set in the prstGeom node and the custom graph is set in the custGeom node. The custGeom node further comprises sub-nodes such as pathlst, cxnlst, gdlst and avlst, which are respectively used for storing related data of the custom graph.
Correspondingly, if the document to be processed is a second type presentation document, the graphic data to be processed can be obtained according to the storage format of the presentation document in pptx format for the graphic data. Specifically, first, document analysis can be performed on the second document to be processed to obtain an analysis file. The analysis process of the second document to be processed mainly comprises file decompression and xml analysis. It should be noted that when the number of slides is large, the data size is relatively large, so that a flexible and efficient parsing method can be adopted in the file decompression process. For example, a 50-page text-to-text mixed presentation has two to three hundred files in a compressed package. At this time, all documents are not required to be decompressed to the memory, and the parsed files are read as required. After the analysis files are obtained, the file style dependency relationship between the target analysis files can be determined according to the dependency relationship files of the analysis files. It will be appreciated that each slide in the pptx format presentation document has a dependency file in addition to the underlying data itself. The top page slide file in the document is illustratively ppt/slips/slip 1.Xml. The dependency file of the top page slide in the document is ppt/slides/_rels/slide1.Xml. Rels. Therefore, the file style dependency relationship between the target analysis files can be determined according to the dependency relationship files obtained by analysis. The target resolution file may be a slide, a template, and a master. Specifically, a template (slidelayout) on which the current slide depends can be found through a dependency file slider xml. Rels of the top page slide, a master (SLIDEMASTER) pointed by the template is found through a dependency file slider layout1.Xml. Rels of the template, information of the master is read, and three groups of data of slide, slidelayout and SLIDEMASTER are summarized finally. File style dependencies exist between slide, slidelayout and SLIDEMASTER: slide-template-master. Correspondingly, after the file style dependency relationship between the target analysis files is obtained, the graph searching sequence can be determined according to the file style dependency relationship. That is, the graphic search order may be determined as: slide-template-master. And carrying out repeated-free graphic data searching on the graphic data included in the target analysis file according to the graphic searching sequence of the slide, the template and the mother plate, so as to obtain second graphic data to be processed.
According to the scheme, the graphic data to be processed are sequentially searched in the second document to be processed according to the determined graphic searching sequence, so that the searching efficiency of the graphic data can be improved, and the comprehensiveness of graphic searching is ensured.
It should be noted that, the above process of obtaining any type of graphics data to be processed in any type of document to be processed may be completed by a multi-format parser in the general graphics element conversion system.
S220, acquiring unified analysis format data of the graphic data to be processed.
The unified parsing format data may be graphic data obtained by defining graphic data to be processed by a general graphic element conversion system according to a predefined unified data definition format.
In order to realize efficient processing of graphics of the data to be processed, the universal graphics element conversion system may redefine the graphics data to be processed by using a predefined uniform data definition format after acquiring the graphics data to be processed, so as to acquire uniform parsing format data corresponding to the graphics data to be processed. Fig. 6 is a schematic diagram of a data structure of unified parsing format data according to an embodiment of the present application. In a specific example, as shown in fig. 6, the conversion of the unified data format of the graphics data to be processed may be completed by defining a unified data definition format formed by fields such as a graphics object, a graphics object attribute, a custom graphic, and a predefined graphic, so as to obtain unified parsing format data.
S230, judging whether the graphic data to be processed is of a first graphic type, if so, executing S240, otherwise, executing S250.
Wherein the first graphic type may be a predefined graphic type in the document to be processed.
S240, converting the graphic attribute data according to the unified analysis format data into the unified format graphic data.
It can be understood that, since the predefined graphics in the document to be processed are usually simple graphics shapes, and the original graphics data including specific data such as shapes and positions can be directly restored according to the unified parsing format data obtained from the graphics data to be processed. Therefore, if the first graphic type is included in the document to be processed, the graphic data to be processed of the first graphic type can be converted into the graphic data of the unified format directly according to the graphic attribute data of the unified parsing format data.
For example, for the to-be-processed graphic data of simple predefined graphics such as line segments, circles or rectangles, the to-be-processed graphic data can be directly converted into the corresponding to-be-processed graphic data according to the information such as the graphic attribute and the like included in the unified analysis format data converted from the read to-be-processed graphic data, so that the conversion efficiency of the to-be-processed graphic data is improved. Alternatively, the graphics data to be processed of the first graphics type may be understood as predefined graphics types as corresponding graphics data of a uniform format.
S250, determining the graphic data to be processed as a second graphic type, and determining datum point data of datum points in the unified analysis format data.
The second graphic type may be a graphic type customized in the document to be processed. The datum point data may be related data of datum points in the graph corresponding to the graph data to be processed, such as the number and the positions of the datum points, the connection mode among the datum points and the like.
It will be appreciated that since custom graphics in a document to be processed are typically relatively complex graphic shapes, such as multi-segment curves, irregular polygons, or curved polygons, etc. Graphics attribute data directly from unified parsing format data may not be converted into unified format graphics data. Therefore, in the embodiment of the present application, if it is determined that the graphics data to be processed is the second graphics type, the reference point data of the reference points in the unified parsing format data may be first determined.
And S260, determining the updating offset according to the graph attribute data of the unified analysis format data.
The update offset may be an offset of a new target position corresponding to the graphics shape corresponding to the graphics data to be processed after the data format conversion with respect to an original position in the document to be processed.
S270, determining target position coordinates of the datum point according to the updating offset.
The target position coordinates may be coordinates corresponding to a new target position corresponding to a graphics shape corresponding to the graphics data to be processed after data format conversion.
S280, converting the datum point data, the target position coordinates and the graphic attribute data into the graphic data in the unified format.
For most of complex graphics in the document to be processed, such as the graphics data to be processed corresponding to the second graphics type included in the document to be processed, the graphics data needs to be parsed into a custom graphics data type. Specifically, a plurality of reference points may be defined for the graphics shape corresponding to the graphics data to be processed, and the reference point data, such as the number and the position of the reference points, the connection mode between each reference point, and the like, may be obtained. The connection manner between the reference points may include various types, such as a straight line, a quadratic bezier curve, a cubic bezier curve, and a circular arc. Accordingly, after the datum point data is obtained, the updating offset of the new target position can be obtained according to the graph attribute data of the unified analysis format data, so that the new target position coordinate of the datum point can be calculated. The target position coordinate data of the new reference point may be stored in pathLst (drawn path) nodes in the unified parsing format data. After the datum point data and the target position coordinates corresponding to the datum point are obtained, the datum point data, the target position coordinates of the datum point and the graphic attribute data in the unified analysis format data can be converted into the unified format graphic data, so that the accuracy and the reliability of the conversion of the graphic data to be processed are ensured. Alternatively, the graphics data to be processed of the second graphics type may be corresponding to the graphics data of the unified format and may be understood as a custom graphics type.
