Example one
The embodiment provides a storage method of a scalable vector diagram file, which is applied to an android system, and please refer to fig. 1, where the method includes:
step S101: a plurality of scalable vector map files to be processed is obtained, wherein the scalable vector map files comprise a namespace and a frame.
Specifically, a scalable vector graphics file, i.e., an SVG file, is a file for describing two-dimensional graphics using an XML language. Typically, an SVG file includes the following components: XML Header (Header), SVG NameSpace (NameSpace), SVG Framework (Framework), Description (Object indication and Description), and SVG graphics Object (Graphic Object).
Step S102: and classifying the scalable vector graphics file to be processed based on the namespace.
In particular, to better classify different scalable vector graphics files, classification may be based on a namespace, which is a file marking method, e.g., with 5 different SVG files, A, B, C, D, E5 SVG files may be distinguished by way of the namespace and marked accordingly.
Step S103: and archiving the classified scalable vector graphics files based on the frame to obtain an archived first scalable vector graphics file, and constructing a library file organization model based on the first scalable vector graphics file.
Specifically, as the namespaces of the SVG types of the same type are the same, in order to better manage the SVG files, the classified files can be filed through an SVG Framework, and the SVG Framework is a unique identifier which is different from the SVG files and other SVG files, so that the Framework + namespace mode can be used as a standard for classified filing, and then a library file organization model is constructed. The library file organization model may be a tree structure or other structure.
In a specific implementation process, the classified scalable vector graphics files are archived based on a framework, and the 5 SVG files may be respectively archived: AB is classified as first gear, CDE is classified as first gear.
Step S104: and segmenting the head and the description of the first scalable vector map file to obtain a second scalable vector map file.
Specifically, because the header and description of the SVG file only describe some description information of the file, the embodiment of the present invention can reduce the space occupied by the SVG by dividing the above parts, thereby improving the storage efficiency.
Step S105: storing the second scalable vector graphics file into the library file organization model.
In an alternative embodiment, after storing the second scalable vector map file into the library file organization model, the method further comprises;
and generating an index file and a library file of the second scalable vector map file.
Specifically, each line of the index file includes a file or a directory name, a starting line number (begin line) and an ending line number (end line) of the file in the library, and in a specific implementation process, a library file index format needs to be defined first, and the format of the index file is as follows:
Directoryname1beginline endline；
Filename1beginline endline；
Filename1beginline endline；
Directoryname2beginline endline；
……
FilenameN beginline endline；
wherein, Directoryname1 and Directoryname2 represent folder names, Filename1 represents file names, begin line represents start line number, and end line represents end line number.
In an alternative embodiment, after storing the second scalable vector map file into the library file organization model, the method further comprises:
and setting a management model of the library file organization model, wherein the management model comprises a file interface for reading files and a library interface for adding and deleting files.
Particularly, in order to manage the library file organization model, the invention also provides a management model of the library file organization model, because large batch of SVG files in the library file organization model need a management interface for external access and processing. In a specific implementation process, the implementation of the file interface and the library interface is as follows:
interface SVGFile:SVGElement{
readonly attribute unsigned long SVGFilelength；
readonly attribute unsigned short SVGFilemode；
}
the SVGFilength is a read-only unsigned long integer parameter, and the parameter SVGFilength is a read-only unsigned long integer parameter.
interface SVGFileLib:SVGFile{
readonly attribute unsigned long SVGFileNumber；
readonly attribute unsigned long FileName；
Bool ReadFile(Cstring Filename)；
Bool WriteFile(Cstring Filename)；
Bool DeleteFile(Cstring Filename)；
Bool FindFile(Cstring Filename)；
}
Wherein, SVGFileLib is the library interface class, SVGFElement is the subclass of SVGFile class, contain parameter SVGFileNumber (SVG file quantity) and parameter FileName (SVG file name), the method of Boolean type in the library interface class: a read file method ReadFile, a write file method WriteFile, a delete file method DeleteFile and a find file method FindFile.
In a specific implementation process, the method can be realized by adopting a language combining Java and C + +, firstly, classifying the SVG files through a file marking method, namely a name space, distinguishing different SVG files, and then filing the classified SVG files through frame marking, so that a library file organization model of the SVG is constructed; in addition, the SVG file is managed by setting a library file organization model file interface and a library interface; the SVG file is divided through a dividing method, so that the storage efficiency of the SVG file is improved.
Based on the same inventive concept, the invention also provides a method for reading the scalable vector diagram file, which is specifically referred to as embodiment two.
Example two
An embodiment of the present invention provides a method for reading a scalable vector diagram file, please refer to fig. 2, where the method includes:
s201: acquiring an index file of a scalable vector map file, wherein the scalable vector map file comprises a namespace and a frame, the index file is generated after the scalable vector map file is stored in a library file organization model, the library file organization model is constructed and obtained based on a first scalable vector map file after being filed, the first scalable vector map file is obtained after the scalable vector map file after being classified is filed based on the frame, and the scalable vector map file after being classified is obtained after the scalable vector map file is classified based on the namespace;
in an optional implementation mode, if an SVG file does not have an index file, it indicates that the SVG file is not in the library file organization model, and directly returns the information that the SVG file does not exist.
Since the process of acquiring the first scalable vector graphics file and the library file organization model has been described in detail in the first embodiment, it is not described herein again.
S202: obtaining a library file of the scalable vector graphics file based on the index file;
specifically, the index file is generated after the SVG file is stored in the library file organization model, the index file comprises the SVG file name, the starting line number and the ending line number, and the library file of the scalable vector graphics file can be obtained through the index file, wherein the library file is a library information file stored by the SVG file and can comprise information such as the type of the file in the library, the library interface address and the like.
S203: and reading a second scalable vector map file from the library file organization model based on the index file and the library file, wherein the second scalable vector map file is obtained by dividing the header and the description by the first scalable vector map file.
In an alternative embodiment, after reading the second scalable vector map file from the library file organization model, the method further comprises:
and inserting the header and the description into the second scalable vector map file to obtain the original scalable vector map file.
Specifically, since the SVG file stored in the library file organization model is divided, in this embodiment, after the second scalable vector graphics file is obtained, the header and the description need to be supplemented, so as to obtain a complete SVG file.
When the library file organization model is in a tree structure, the SVG file is searched or read by adopting the existing method. Generally, searching is started from a treetop point or a treetop point of a tree structure until a corresponding file is found, when the number of files stored in a library file organization model library is large, the efficiency of the existing searching mode is low, and the searching and reading mode of the index file in the application can greatly improve the searching efficiency, so that the efficiency of reading the SVG file is improved. Furthermore, when the SVG file is searched by using the index file, the SVG file can be further searched by combining a binary search method.
To describe the SVG file reading method in the embodiment of the present invention more clearly, as will be described in detail below by using a specific example, it is first determined whether an index file exists in an SVG file, if so, a library file is obtained from the index file, and then a second scalable vector image file is read from the constructed library file organization model based on the index file and the library file, and a binary search algorithm may be further incorporated in the process of reading the file, thereby further improving efficiency.
