Alternative embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

A first embodiment, an embodiment of a method of editing a presentation, is provided for the present disclosure.

The embodiment of the present disclosure is described in detail below with reference to fig. 1, where fig. 1 is a flowchart of a method for editing presentation content provided by the embodiment of the present disclosure.

And step S101, acquiring editing track information of the current slide of the presentation from the touch screen.

In the embodiment of the present disclosure, the terminal for playing the presentation may be a notebook computer or a personal computer, and a touch screen is usually installed in front of a display screen thereof. The touch screen includes: a resistive touch screen, a capacitive touch screen, an infrared touch screen, or an acoustic wave touch screen.

A presentation is made up of a series of slides. The current slide of the presentation is the slide currently displayed on the display screen.

The edited trajectory information includes a series of trajectory point information. The edited track information at least comprises an end point mark of the track point. Location information and time stamps of the track points are also typically included, and sometimes start point markers of the track points.

The starting point mark of the track point is used for indicating that the track point is the starting point of a section of track. And an end point marker for a track point indicates that the track point is an end point of a segment of the track. And in the time range from the timestamp corresponding to the starting point to the timestamp corresponding to the ending point, the track points corresponding to the timestamps belonging to the time range belong to the same continuous track.

And step S102, capturing the screen information of the current slide.

See fig. 2 for screen information on the current slide.

For capturing the content of the current slide in the presentation, a software interface provided by a development company to which the presentation software belongs is generally required. However, such software interfaces require complicated calls for acquiring contents, are long in time and are inefficient.

The disclosed embodiments provide a more convenient and faster method. Specifically, the step of grabbing the screen information of the current slide includes the following steps:

and step S102-1, capturing the screen information of the current slide from a display memory.

I.e. what is currently displayed, i.e. what we need to edit.

And step S103, synthesizing the screen information and the editing track information to generate an editing image.

For editing the image, please refer to fig. 3.

The present embodiment is not described in detail with respect to the synthesis process, and can be implemented by referring to various implementations in the prior art.

The method for editing slides in a presentation by calling a software interface often requires editing the slides according to rules set by a development company to which the presentation software belongs. The method provided by the embodiment of the disclosure bypasses complex calling and directly processes the display information, thereby avoiding processing the logical relationship in the slide, simplifying the editing method and improving the processing efficiency.

The processing efficiency is improved in order to avoid resource consumption caused by frequent image synthesis. The synthesizing the screen information and the editing track information to generate an editing image comprises the following steps:

and step S103-1, when the track point mark is an end point mark, synthesizing the screen information and the editing track information to generate an editing image.

I.e. the image composition is only performed at the end of a continuous track.

And step S104, displaying the edited image on a display terminal.

Optionally, the displaying the edited image on a display terminal includes:

and step S104-1, writing the edited image into a display memory corresponding to the display terminal.

By directly writing the edited image into the display memory, the display efficiency is further improved.

Optionally, the method further comprises the following steps:

and step S105, when the track point mark is an end point mark, transmitting the edited image to a remote terminal so that the remote terminal can display the edited image.

The processing method not only ensures the real-time performance of the information, but also reduces the network flow and improves the data processing efficiency.

The disclosed embodiments also provide a method for further processing slides of a presentation. The method further comprises the steps of:

and step S111, acquiring a page turning signal.

The page turning signal can be obtained through a page turning key in a keyboard or a page turning key of a movable page turning pen.

Step S112, based on the triggering of the page-turning signal, acquiring a first slide number of the presentation before page turning and a second slide number of the presentation after page turning.

The slides in the presentation are numbered according to the display sequence. There may be multiple pages in each slide, and the content of each page is not completely the same.

The page turning signals include an up turning signal and a down turning signal. The pages in each slide can be changed by the page turning signal. When the first page is displayed in the slide, the flip up signal will cause the presentation to go to the previous slide. When the last page is displayed in a slide, the flip down signal will cause the presentation to go to the next slide.

Step S113, when the first slide number is equal to the second slide number, screen information of a second slide is captured; and synthesizing the screen information and the editing track information to generate an editing image and displaying the editing image on a display terminal.

When the first slide number is equal to the second slide number, it indicates that the page-turning signal only triggers the turning of pages in the same slide, i.e., that the pages have changed. There is typically inheritance of the content of each page in the same slide. Therefore, it is only necessary to re-synthesize the slide show with the new page image based on the edit trajectory information of the slide show.

Step S114, when the first slide number is not equal to the second slide number, the editing track information is cleared.

When the first slide number is not equal to the second slide number, it indicates that a page flip signal triggers a flip into a new slide. The editing track information of the previous slide is already unrelated to the current slide, and thus, the editing track information of the previous slide is cleared.

The embodiment of the disclosure bypasses complex software interface calling and directly processes the display information. The method avoids the processing of the logical relation in the slide, simplifies the editing method and improves the data processing efficiency.

The present disclosure also provides a second embodiment, namely, an apparatus for editing a presentation, corresponding to the first embodiment provided by the present disclosure. Since the second embodiment is basically similar to the first embodiment, the description is simple, and the relevant portions should be referred to the corresponding description of the first embodiment.
