It should be noted that, the width and height of the first operation layer of the first electronic whiteboard are the same as the width and height of the first electronic whiteboard, and the width and height of the second operation layer are the same as the width and height of the second electronic whiteboard, so the first width-to-height ratio may also represent a ratio of the width to the height of the first operation layer, and the second width-to-height ratio may also represent a ratio of the width to the height of the second operation layer.

In a specific embodiment of the present application, after obtaining the first drawing result, the first electronic whiteboard draws the first drawing result on the first operation layer, and sends the first drawing result to the second electronic whiteboard, and performs synchronous display on the second display layer. It is understood that after the first drawing result is obtained, the first user on the first whiteboard side may view the first drawing result displayed on the first operation layer through the first electronic whiteboard, and the second user on the second whiteboard side may view the first drawing result displayed on the second display layer through the second electronic whiteboard.

Here, a response process of the first electronic whiteboard in response to a screen switching operation performed by the first user on the first electronic whiteboard is described, and the response process may include:

In a specific embodiment of the present application, the first electronic whiteboard further includes a first history layer in addition to the first operation layer and the first display layer, and the second electronic whiteboard further includes a second history layer in addition to the second operation layer and the second display layer.

Taking fig. 3 as an example, fig. 3 is a schematic diagram of implementation logic of obtaining a first fusion result by a first electronic whiteboard provided in the present application, in fig. 3, a solid line box represents the electronic whiteboard, a dashed line box represents an operation layer and a display layer, and fig. 3 shows three layers of the first electronic whiteboard: a first operation layer, a first display layer, and a first history layer, only a second history layer of the second electronic whiteboard being shown. In an initial situation, a first drawing result of the first operation layer is a circle, a second drawing result of the first display layer is a rectangle, a history drawing result of the first history recording layer is a curve, the first electronic whiteboard responds to a screen switching operation executed by a first user on the first electronic whiteboard, and the first drawing result of the first operation layer, the second drawing result of the first display layer and the history drawing result of the first history recording layer are fused to obtain a first fusion result: circular, rectangular and curved, and synchronizing the first fused result to a second history layer of the second electronic whiteboard.

It is understood that fig. 3 is only an example, and in practical applications, the first rendering result, the second rendering result, and the historical rendering result may be other or more, and therefore, the obtained first fusion result may also be more or other, and is not limited in particular herein.

In practical application, the first electronic whiteboard responds to a screen switching operation executed by a first user on the first electronic whiteboard, and the process of obtaining a first fusion result by fusing the drawing results of the first operation layer, the first display layer and the first history layer may be as follows:

the first method comprises the following steps: and then, the first drawing result of the first operation layer and the initial fusion result of the first history layer are fused to obtain a first fusion result, and the first fusion result is stored in the first history layer.

And the second method comprises the following steps: the method comprises the steps of firstly fusing a first drawing result of a first operation layer with a first history drawing result of a first history recording layer to obtain an initial fusion result, storing the initial fusion result to the first history recording layer, then fusing a second drawing result of a first display layer with the initial fusion result of the first history recording layer to obtain a second fusion result, and storing the second fusion result to the first history recording layer.

And the third is that: and simultaneously fusing the first drawing result of the first operation layer and the second drawing result of the first display layer with the first history drawing result of the first history recording layer to obtain a first fusion result, and storing the first fusion result to the first history recording layer.

It should be noted that, in response to a screen switching operation performed by a first user on a first electronic whiteboard, the first electronic whiteboard may further perform other processes to fuse drawing results of the first operation layer, the first display layer, and the first history layer to obtain a first fusion result, for example, the first drawing result of the first operation layer and the second drawing result of the first display layer may be fused first to obtain an initial fusion result, and the initial fusion result is stored in the first operation layer or the first display layer.

In practical applications, the first electronic whiteboard may display pages, such as a first page, a second page, and the like, and it is understood that when the first user performs a screen switching operation on the first electronic whiteboard, the first electronic whiteboard may switch between pages, may switch from a front page to a rear page, and may also switch from a rear page to a front page, and the switching is not limited in particular herein. Therefore, when the first drawing result of the first operation layer and the second drawing result of the first display layer are fused with the history drawing result of the first history layer to obtain the first fusion result, the first drawing result of the first operation layer and the second drawing result of the first display layer may be cut according to a page, and then the first drawing result and the second drawing result on the cut page may be fused with the first history drawing result on the corresponding page of the first history layer. If the first page is displayed on the lower right corner of the first electronic whiteboard, when the first user performs a screen switching operation on the first electronic whiteboard, the first electronic whiteboard fuses the drawing result (including the first drawing result and the second drawing result) of the whole page of the page (the first page) and the first history drawing result of the first page on the first history recording layer.

In practical applications, the screen switching operation performed by the first user with respect to the first electronic whiteboard may be a screen switching operation implemented by the first user sliding on the first electronic whiteboard through a specific input device (e.g., a stylus, a keyboard, a mouse, etc.), or may also be a screen switching operation implemented by the first user sliding a finger on the first electronic whiteboard, for example, the screen switching operation is implemented by actions of the first user rotating the finger on the first electronic whiteboard to the left, to the right, up, down, clockwise, or counterclockwise, which is not limited specifically herein.
