Problems solved by technology

[0002] Although the existing screen annotations allow the speaker to annotate the content on the screen, the speaker must make annotations on the podium. These annotations are generally temporary and do not need to exist all the time. People behind can't see clearly, which will affect the presentation effect

Embodiment Construction

[0020] Such as figure 1 As shown, a method for screen annotation of the present invention needs to provide a server and a client, the server and the client are connected using TCP, the server is responsible for displaying the annotation content of the client, and the client is responsible for The server file is annotated and the content of the annotation is sent to the server. The method includes the following steps:

[0021] Step 1. The client connects to the server and enables the annotation function;

[0022] Step 2. The server captures the current screen picture, displays the full-screen top original picture on the screen, and sends the captured picture to the client;

[0023] Step 3. The client displays the picture, draws the annotation, and sends the annotation content to the server;

[0024] Step 4. The server calculates the zoom ratio according to the screen size information of the client device and the screen size of the server itself, draws the annotation content o...

Abstract

The invention provides a screen annotation method. A server and a client need to be provided; the server is connected with the client through TCP; the server is used for displaying annotation contents of the client; the client is used for annotating a file of the server and sending the annotation contents to the server. The method comprises the following steps: the client is connected with the server, and an annotation function is started; the server captures a current screen picture, displays the picture on a screen in a full-screen top original drawing manner and sends the captured picture to the client; the client displays the picture, draws an annotation, and sends the annotation contents to the server; the server calculates a zoom scale according to size information of a device screen of the client and a size of a native machine screen of the server, drawing the annotation contents on the picture according to the zoom scale, and re-displaying the picture. The screen annotation method realizes annotation moving and annotation zooming on the screen, so that key contents can be highlighted conveniently by a lecturer, the demonstration effect is enhanced, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the field of document processing, in particular to a method for screen annotation. Background technique [0002] Although the existing screen annotations allow the speaker to annotate the content on the screen, the speaker must make annotations on the podium. These annotations are generally temporary and do not need to exist all the time. People behind can't see clearly, which will affect the demonstration effect. Therefore, there is a need for an annotation method that allows the speaker to perform mobile annotations, and at the same time, can meet the needs of zooming, and display the content in focus, so that everyone present can watch it. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for on-screen annotation, which can move and zoom the content on the screen that needs to be annotated, so as to facilitate the emphatic display of the content that the ...
