In order to make a person skilled in the art to understand the disclosed subject matter better, in the following, a further detailed illustration will be made with reference to the appended drawings.
In methods for changing a font for an application program, in a server, multiple fonts are selected to constitute a set of available fonts, so as to satisfy different wording requirements in different scenes for various application programs. In addition, update and issue of font resources are controlled by the server. In one hand, this makes the application program not need to carry and manage font resources, which reduces the application program's burden; on the other hand, while the font resources need to be updated, this can be completed in the server conveniently, so as to update the font resources without updating the edition of the application program, which reduces the iteration cost of the application program and provides better user experiences.
Specifically, the font resource may include contents, such as the number of available fonts, font names, characters, pictures and small character library used to present the fonts, font files and so on. While the server selects the fonts to constitute the set of the fonts, it should be guaranteed that the types of fonts are abundant and the styles of fonts are representative and complementary, so as to satisfy various different of certain font requirements.
As shown in
In step 101, when it is need to change a font for an application program, a client sends a request for obtaining information on available font resources to a server.
The request may contain information on font resources that the client currently has. Before the server issues the information on available font resources to the client, the server determines whether there is new currently available font resources need to be issued to the client according to the information on the font resources that the client currently has. If yes, the server issues only the new font resources to the client; if no, the server notifies the client that there is no the new currently available font resources. In this way, it is possible to avoid repeatedly issuing the font resources that the client has, which saves the network traffic and the loading duration, and improves the user experiences.
The request may contain information on the version number of the font resources that the client currently has, which is used as an identifier of the font resources that the client currently has.
In step 102, the client presents the information on the currently available font resources after receiving the same from the server.
The information on the currently available font resources may include font style, font typesetting effect, recommended scenes for the font, etc. A method of presenting the information is not to present pictures but to directly present characters by using a small character library extracted from the current character library.
For instance, a section of characters in the small character library can be used to present the font style and the font typesetting effect, and the section of characters contain the recommended scenes.
Of course, other presenting methods can be adopted as well, and the presented content is not limited to the above mentioned information.
In step 103, the client determines a font selected by a user.
Specifically, while presenting the information on the currently available font resources, a selection mode should be presented to the user at the same time, the user selects a desired font according to his preferences. For instance, a selection button is provided corresponding to each font, of course, other available way is to allow a user to click the selected character by a mouse directly. Certainly, there should be other selection modes.
In step 104, the client downloads the selected font from the server.
The download of the font may support resuming of file transfers. And during the download, the equipment at the client side can still process other operations without being locked in a wait mode.
Specifically, one way to support resuming of file transfers is to manage the downloaded information as a temporary file.
In a download method, a new thread is started up to process the download at the back stage, so that the equipment may not be locked in the wait mode.
In step 105, the client sends the downloaded font to the application program, so that the application program can replace the currently used font with the downloaded font.
It should be noted that, in practical applications, after downloading the selected font from the server, the information on the currently available font resources could also be sent to other application programs that are interested in the change of font resources. For instance, the information on the currently available font resources is sent to other application programs by a system broadcast which sends fixed parameters, and these application programs that are interested in the change of font resources can obtain the newly information on the available font resources only by registering a broadcast receiver with the operation system installed in the equipment.
It can be seen that, the method for changing a font for an application program according to the embodiment of the present invention can conveniently change a font for an application program as needed at any moment. Besides, since the server controls the update and issue of the font resources, the application program does not need to contain and manage the font resources. The Server can update the available font resources as needed at any moment, which provides the application program with more font resources and better user experiences.
Furthermore, it is also possible to make multiple application programs share this method, which can save equipment resources and achieve a convenient centralized management.
In this example, the client apparatus includes:
a request sending module 201, configured to send a request for obtaining information on available font resources to a server when it is need to change a font for an application program;
a font information receiving module 202, configured to receive information on currently available font resources returned from the server;
a font presenting module 203, configured to present the information on the currently available font resources after the font information receiving module receives the information on the currently available font resources returned from the server;
a selection information obtaining module 204, configured to determine a font selected by a user;
a font download module 205, configured to download the selected font from the server; and
a font management module 206, configured to send the downloaded font downloaded by the font downloading module to the application programs, so that the application program replaces the currently used font with the downloaded font.
The request may include information on fonts that the client currently has, such as the version number of the current font resources, so that the server can determine whether there are new font resources to be issued to the client according to the information. If yes, the server issues only the new font resources to the client; if no, the server notifies the client that there is no the new currently available font resources. In this way, it is possible to avoid repeatedly issuing the font resources that the client has, which saves the network traffic and the loading duration, and improves the user experiences.
The information on the currently available font resources returned by the server may include font style, font typesetting effect, recommend scenes for the font, etc.
In practical applications, the font presenting module 203 mentioned above may adopt multiple methods to present the information on the currently available font resources. For example, the font presenting module may not present pictures but directly present characters by using a small character library extracted from the current character library. Specifically, a section of characters in the small character library can be used to present the font style and the font typesetting effect, and the section of characters contain the recommended scenes. Of course, other presenting methods can be adopted as well, and the presented content is not limited to the above mentioned information.
The font download module 205 mentioned above may support resuming of file transfers, the equipment at the client side can still process other operations without being locked in a wait mode. For example, a thread is started up to download the selected font from the server at the back stage and the downloaded information is managed as a temporary file, so that download is performed by the thread at the back stage and the client may be not locked in the wait mode.
In addition, in practical applications, the font managing module 206 mentioned above can not only send the font downloaded by the font download module 205 to the application program that sends the request to the server directly, but also send the information on the currently available font resources received by the font information receiving module 202 to other application programs that are interested in the change of font resources, for example, send to other application programs by broadcast. These application programs that are interested in the change of font resources can obtain newly information on the available font resources only by registering a broadcast receiver in the application program by the operation system installed in the equipment.
It can be seen that the client apparatus can conveniently change a font for an application program as needed at any moment. Besides, since the server controls the update and issue of the font resources, the application program does not need to contain and manage the font resources. The Server can update the available font resource as needed at any moment, which provides the application program with more font resources and better user experiences.
Furthermore, it is also possible to make multiple application programs share this client apparatus, which can save equipment resources and achieve a convenient centralized management.
The system can include a client apparatus 301 and a server 302. Wherein, the server is configured to receive a request for obtaining information on available font resources sent by the client apparatus, and send the information on the currently available font resources to the client apparatus after receiving the request.
The structure of the client apparatus can be understood with reference to the foregoing description and the details are omitted.
Communications between the client apparatus 301 and the server 302 could adopt existing standard protocols or self-defined network protocols, the embodiment of the present invention will not limited thereto.
In the system for changing a font for an application program, since the server controls the update and issue of the font resources, the application program does not need to contain and manage the font resources. The Server can update the available font resources as needed at any moment, which provides the application program with more font resources and better user experiences. Furthermore, it is also possible to make multiple application programs share this system, which can save equipment resources, and achieve a convenient centralized management.
