Embodiment 1

[0015] Such as figure 1 As shown, a specific embodiment of the present invention is a method for synchronizing the whiteboard after the picture is centered under different resolutions, which specifically includes the following steps:

[0016] Step 101: The source user opens a webpage, and the webpage automatically loads a Flash plug-in, and the Flash plug-in establishes a permanent connection with the communication server, and starts to monitor the data transmission of the communication server.

[0017] The above-mentioned technical scheme specifically includes the following processes:

[0018] When the source user opens the webpage, the webpage automatically loads the Flash plug-in, and the Flash plug-in establishes a permanent connection with the communication server through the XMLSocket class, and starts to monitor the data transmission of the communication server.

[0019] Step 102: The source user loads the Flash, sets the scaling mode of the Flash to non-zooming, and s...

Embodiment 2

[0052] A specific embodiment of the present invention is a system for synchronizing whiteboards after centering pictures at different resolutions, including a source user, a communication server, a synchronization storage server and a target user, wherein:

[0053] The communication server authenticates the authority of the received source user to send the picture state information and after the authentication is passed, authenticates the authority of the target user to receive the picture state information and after the authentication is passed, the communication server will obtain the picture state information Send to the synchronous storage server;

[0054] The synchronous storage server stores and updates the picture state information, and sends the updated picture state information to the target user and the source user.

[0055] The working principle of this embodiment is described in detail below according to the accompanying drawings:

[0056] When the source user ope...

Abstract

The invention discloses a method and a system for synchronizing a whiteboard after picture centering under different resolutions, which are applied in the technical field of networks. The method comprises the following steps that: a communication server authenticates the rights of picture state information received from a source user, authenticates the receiving rights of a target user over the picture state information after the rights of the picture state information pass the authentication, and transmits the acquired picture state information to a synchronous storage server after the receiving rights of the target user over the picture state information pass the authentication; and the synchronous storage server stores and updates the picture state information, and transmits the updated picture state information to the target user and the source user. By the method and the system, the whiteboard synchronization after the picture centering is realized and synchronized information security is ensured without downloading and installing any piece of software.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method and a system for synchronizing whiteboards after pictures are centered under different resolutions. Background technique [0002] With the development of Internet technology, people's lives have also changed, gradually changing from a traditional way of life to an information-based way of life. With the help of the Internet, people can watch TV online, read books, make friends, make phone calls, send emails, and read news... Information-based life has become an indispensable part of our lives. Of course, people must rely on hardware devices such as keyboards, mice, monitors, headsets, and cameras to fully experience the convenience of the Internet and the richness of information-based life. The monitor is the most important device that occupies the largest space in the above-mentioned hardware. The size of its display area will directly affect people's expe...
