Show relative position information of the region relative to the display interface.
Specifically, step S101, comprising:
Step A1: the characteristic information of the display interface of transmitting terminal is obtained.
Wherein, the characteristic information includes: the dimension information of display interface and the resolution information of display interface.
Step A2: the display interface of transmitting terminal is divided into the sub-viewing areas of setting quantity according to the characteristic information.
Specifically, determining the quantity of sub-viewing areas according to the dimension information of the display interface and resolution information.Son
The quantity of display area increases with the increase of resolution ratio.
Step A3: relative position information of each sub-viewing areas relative to the display interface is obtained.
For example, as shown in Fig. 2, the display interface of transmitting terminal is divided for 8 sub-viewing areas.
Step S102: obtaining image to be transmitted, determines the sub- viewing area of one or more involved in the image to be transmitted
Domain.
Specifically, the image to be transmitted, comprising: draw instruction, drawing fragment or entire image.
Further, one or more sub-viewing areas involved in the determination image to be transmitted, comprising:
According to location information of the image to be transmitted in the display interface and each sub-viewing areas described
Location information in display interface determines sub-viewing areas involved in the image to be transmitted.
For example, as shown in Fig. 2, image to be transmitted is related to the second sub-viewing areas, third sub-viewing areas, the 6th son display
Region and the 7th sub-viewing areas, totally four sub-viewing areas.
Step S103: corresponding transmission data packet is set for each sub-viewing areas involved in the image to be transmitted；
