The element parameters such as number, font color, line space, font spacing.
It,, can be if user clicks the table if inserting table in web page in another example as shown in Figure 2 C
Pop up the edit operation column of the table in web page, user can set line number, columns, cell inset spacing, border width,
The element parameters such as border color.
It should be noted that these element parameters can phase with the type of editor that can be directly carried out to PowerPoint element
Together, can not also be identical, the embodiment of the present invention does not limit this.
For the editor of PowerPoint element arrangements, user can preserve manually, can also client executing web page
Script automatically saves, and to the parameter of PowerPoint element arrangements in web page, can be carried out when stored with server same
Step, server stores the parameter to the PowerPoint (being represented with PowerPoint mark), subsequently to be loaded.
Certainly, if formerly having generated PowerPoint, the information of the PowerPoint can be shown in regions such as customer centers,
After user clicks, client is joined while using web page is loaded for the URL of editor according to the element formerly set
Number loads corresponding PowerPoint element, and so that user continues to edit, the embodiment of the present invention does not limit this.
Step 103, audio data is added to the PowerPoint element on a timeline, to be played according to the time shaft
The audio data is played simultaneously during the PowerPoint element.
In embodiments of the present invention, in order to control the broadcasting of PowerPoint, a time shaft can be configured in client, and sets
PowerPoint element is in the reproduction time of the time shaft.
In addition, user can be with recording audio data, client adds PowerPoint element audio data, such as user
Speech speech, so that while playing audio-fequency data give a lecture etc. operation, playing demonstration document element makes according to time shaft
Obtaining the two can synchronize.
Under editing mode, as shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D, user can set the broadcasting of PowerPoint element
Time over time, while playing audio-fequency data is set, can set switching speech manuscript member in sequence
