Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
a method for stereoscopically displaying a file, as shown in fig. 1, the method comprising:
s101, analyzing the typesetting information in the file.
The layout information includes graphic elements and layout elements of the graphic elements.
In particular, the graphical elements include text passages, primitive geometries, compound geometries, pictures, charts, tables, and/or formulas.
The composition element includes the position of the graphic element on the display page and other constraint information related to the display. The specific other constraint information includes a relative positional relationship between the graphic elements. The purpose of recording the typesetting elements of the graphic elements is to ensure that the specific positions and relative position relations of the graphic elements in the display result are consistent with the record of the specific positions and relative position relations of the graphic elements in the file in the process of stereoscopically displaying the file.
The embodiment can analyze common Office files, and specifically, can analyze files supported by a Microsoft Office suite, including Word files, Excel files, and PowerPoint files. The files supported by the Microsoft Office suite are generated according to the Microsoft custom rule, and the files supported by the Microsoft Office suite can be analyzed according to the custom rule. The files supported by the Microsoft Office suite include two coding forms, the Microsoft Office uses a Binary (Binary) coding form before the 2007 version, and then uses an OpenXML form, which is an Ecma Office OpenXML, and is an international open standard for word processing documents, presentations and spreadsheets.
In order to analyze both the files in the two encoding forms, as shown in fig. 2, the present embodiment first determines the encoding form of the file, then determines which component (Word, Excel, and PowerPoint) in the Microsoft Office suite supports the file, and analyzes the file according to the two determination results. The analysis result further includes other information, which is information unrelated to stereoscopic display, and may include editing information, such as recording a last editing position or revision information, and may also include encryption information, such as an open password and an edit password of a file; in addition, attribute information, such as external links and author information, may also be included.
And S102, generating a three-dimensional display model corresponding to the file according to the typesetting information and three-dimensional display parameters corresponding to the graphic elements according to a preset typesetting rule.
The preset typesetting rule comprises typesetting the graph according to the typesetting elements of the graph elements and keeping the level positions of the graph elements in the three-dimensional display model consistent with the level positions of the graph elements recorded in the file.
Specifically, the preset typesetting rule further includes that the stereoscopic display parameters corresponding to the graphic elements can be modified according to the setting of the user. For example, a user may set a stereoscopic display parameter corresponding to each graphic element, so that different graphic elements can correspond to different three-dimensional display effects. Specifically, the stereoscopic display parameters include an extension direction and an extension angle in the stereoscopic display of the graphic element. For example, an effect of using an upward vertical extension or an upward oblique extension when a certain graphic element is displayed may be defined.
Further, the file parsed in this embodiment is a file supported by the Microsoft Office suite, and the preset layout rule also needs to be compatible with the flat panel display rule of the file supported by the Microsoft Office suite. As another preferred embodiment, the present invention may also parse other office files, and accordingly, the corresponding layout rule is compatible with the display rules of the other office files.
And S103, displaying the file according to the stereoscopic display model.
Describing the stereo display model in a form of a graphic sequence, and constructing a display file according to a description result; each graph in the graph sequence comprises a graph element, a typesetting element of the graph element and a three-dimensional display parameter corresponding to the graph element.
Specifically, the present embodiment provides two rendering manners for implementing stereoscopic display of a file:
(1) rendering files by calling system API (application programming interface)
As shown in fig. 3, a graphics sequence to be displayed is obtained according to the stereoscopic display model, the graphics sequence is decomposed into a combination of basic graphics, and an API of a system is called to draw each graphics respectively. In another embodiment, each graph can be rendered separately using OpenGL. OpenGL (Open Graphics Library) refers to a specialized graphical program interface that defines a cross-programming language, cross-platform programming interface specification. The method is used for three-dimensional images (two-dimensional images can also be used), and is a bottom layer graphic library which is powerful and convenient to call.
(2) Rendering files through OpenGL ES
OpenGL ES (OpenGL for Embedded Systems) is a subset of OpenGL three-dimensional graphics APIs, and is designed for Embedded devices such as mobile phones, PDAs, and game hosts. In a mobile terminal with limited hardware conditions, OpenGL ES can be used to realize stereoscopic display of files.
As shown in fig. 4, a graphics sequence to be displayed is obtained according to the stereoscopic display model, a corresponding OpenGL ES element and instruction are obtained according to the graphics sequence, and OpenGL ES is invoked to implement graphics rendering.
According to the file three-dimensional display method provided by the embodiment, the file is three-dimensionally displayed according to the setting of the user, so that a more vivid display effect can be realized, and the graphic elements in the file can be displayed in a multi-level manner. The effect of opening a PowerPoint file by the Microsoft Office suite is shown in fig. 5, and the effect displayed by using the method in the embodiment is shown in fig. 6, so that the superimposed elements are displayed in different three-dimensional effects, and a user can see each superimposed layer of elements, thereby obtaining a rich and vivid display effect.
Example 2:
a method of stereoscopic display of a file, the method comprising:
s201, analyzing the typesetting information in the file.
The layout information includes graphic elements and layout elements of the graphic elements, and the layout elements include positions of the graphic elements on a display page and other constraint information related to display.
S202, generating a three-dimensional display model corresponding to the file according to the typesetting information and three-dimensional display parameters corresponding to the graphic elements according to a preset typesetting rule.
And S203, displaying the file according to the stereoscopic display model.
Compared with the flat panel display, the file stereoscopic display needs to consume more system resources, and therefore, for a mobile terminal with limited hardware conditions, it is difficult to realize the stereoscopic display of the file, and therefore, the embodiment provides an optimization scheme for the file stereoscopic display method, so that the occupation of the hardware resources in the file stereoscopic display process is saved, the display speed of the file in the stereoscopic display process is increased, and the method in the embodiment can also be suitable for the mobile terminal.
Specifically, in this embodiment, the stereoscopic display model is described in a form of a graphic sequence, and a display file is constructed according to a description result; each graph in the graph sequence comprises a graph element, a typesetting element of the graph element and a three-dimensional display parameter corresponding to the graph element.
And generating an index according to the display file, wherein the index is used for quickly positioning the graphs in the graph sequence. Each graphic element in a page has a corresponding unique identifier id and position information offset, which is used to locate the storage location of the graphic element, and can be an offset location in a binary file, a path in an XML file, a file path on a file system, or a network address URL. The index of a page is represented by a table structure including unique identifiers id and position information offset of all the graphic elements constituting the page. Taking the index establishment for the page of the Word file as an example, as shown in fig. 7, the page includes four graphic elements of a table, a picture, an icon, and a formula.
Further, in the process of displaying the file, acquiring a region to be loaded of the file in real time, obtaining a graphic sequence corresponding to the region to be loaded in the display file according to the index, and displaying graphic elements in the graphic sequence; and graphic elements which are not in the area to be loaded are not processed.
Further, still include:
serializing the displayed graphic elements and generating a graphic recording file;
and if the displayed graphic elements are required to be displayed again after leaving the display area of the file, deserializing the graphic record file and directly displaying the graphic elements according to the deserialization result.
Specifically, the index structure is analyzed, and the Object is generated from the graphic element. The Object is in fact an abstract description of real-world objects in the computer domain, as well as states and behaviors. In this embodiment, the graphic elements are parsed into Object objects according to the unique identifier id and the position information offset, where each graphic element corresponds to one Object, and a page is also an Object and includes the Object corresponding to the graphic elements constituting the page. Taking the Java language as an example, Object can implement serialization and deserialization of objects through the native functionality of Java (an Object oriented programming language) or Json (a Java-compatible lightweight data interchange format).
Further, still include: and acquiring configuration parameters of a terminal for displaying the file, and setting the display precision of the file according to the configuration parameters. For example, if the terminal is a high-definition mobile device, the file is displayed by using high DPI, where DPI is an abbreviation of Dots Per Inch Per inc (dot Per Inch), and a unit of resolution is used, and a larger DPI value indicates that the display precision of the high-definition mobile device is higher. In order to avoid too slow display speed caused by high DPI display, the display precision of the file may be appropriately reduced in step S203 to balance the display speed.
The embodiment provides a file three-dimensional display method, and further provides an optimization technical scheme for progressively loading file contents according to indexes, realizing rapid secondary display of displayed graphic elements in a serialization and deserialization mode, and adjusting display precision according to the configuration of a display terminal, so that the speed of file three-dimensional display is improved, hardware resources required to be consumed in the file three-dimensional display process are reduced, and the embodiment can be particularly used in a mobile terminal with limited hardware conditions.

The display module 303 displays the display file constructed by the display file construction module 304 according to the file and the index generated by the index generation module 305.
Specifically, as shown in fig. 9, the display module 303 includes:
a to-be-loaded region acquiring unit 3031, configured to acquire a to-be-loaded region of the file in real time;
a graphic sequence obtaining unit 3032, configured to obtain, according to the index, a graphic sequence corresponding to the region to be loaded in the display file;

Although fig. 10 shows the WiFi module 170, it is understood that it does not belong to the essential constitution of the terminal, and may be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 180 is a control center of the terminal, connects various parts of the entire terminal using various interfaces and lines, performs various functions of the terminal and processes data by operating or executing software programs and/or modules stored in the memory 120 and calling data stored in the memory 120, thereby performing overall monitoring of the terminal. Optionally, processor 180 may include one or more processing cores; preferably, the processor 180 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.
