Problems solved by technology

During the online conference, the speaker marks the content of the block on the presentation document. If the resolution is different, the monitors of the participants will not display the same block, and it is impossible to accurately locate the traces of the brush. These are the current network video conferences, Common problems in application systems such as distance education and book reading

Embodiment Construction

[0039] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0040] A method for synchronizing whiteboards after centering images at different resolutions on a webpage, comprising the following steps:

[0041] 1) The user opens the web page, loads the flash, sets the zoom mode of the flash to non-zoom, and sets the alignment to upper-left alignment;

[0042] 2) The flash loads the picture that needs to be demonstrated, and according to the size of the picture and the size of the flash, set the picture to be displayed in the center of the whiteboard;

[0043] 3) The user at the control end, after drawing the graphics on the whiteboard, sends the coordinates of the graphics and the coordinates of the picture to all clients;

[0044] 4) After receiving th...

Abstract

The invention belongs to the technical field of networks and particularly relates to a whiteboard synchronizing method, which comprises the following steps of: opening a webpage by a user, loading flash, adding a container for the flash to serve as a whiteboard, loading an image to the interior of the whiteboard by the whiteboard, trigging a complete event after the loading of the image is completed, and centralizing and displaying the image on the whiteboard by a flash program; after a control side user draws a graph on the whiteboard, sending all coordinate data constituting the graph and the coordinates of the currently centralized image to all client sides by the flash at the same time; and renewably calculating the coordinates of the local graphs by the client sides according to the local image coordinates, the image coordinates in a message and the coordinates of the graphs, drawing graphs according to the new coordinates of the graph. According to the method, the labels of all user whiteboards can be completely synchronized under any resolution ratio.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a whiteboard synchronization method. 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, read books, make friends, make phone calls, send emails, and read news online. 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. [0003] 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 experience of the Internet. This makes the otherwise simple and easy...
