Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] The embodiment of the present invention provides a hot picture loading method, such as figure 1 shown, including:

[0044] 101: Send the image data of the hotspot image to the client;

[0045] 102: If the image data of the hotspot image drawn by the instruction client has been sent to the client; send a drawing instruction and the hotspot image identifier to the client, instructing the client to load the texture information of the ...

Abstract

The embodiment of the invention discloses a hot picture loading method, a control server, a client and a system. The hot picture loading method comprises the steps of transmitting data of a hot picture to a client; transmitting a drawing order and a hot picture identifier if the data of the hot picture drawn by the client is indicated to be already transmitted to the client, and instructing the client to load texture information of the data corresponding to the hot picture identifier. By adopting the scheme, the hot picture identifier corresponding to the hot picture is established, only the hot picture identifier is needed to transmit when the client is instructed to draw the hot picture, and the hot picture is unnecessary to transmit, so that the transmission volume of the picture data can be reduced, and the network load can be reduced. In addition, since the picture data is not required to transmit repeatedly, the client is unnecessary for establishing the repeated texture information, so that the memory usage can be reduced, and the system performance of the client can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for loading a hotspot picture, a control server, a client and a system. Background technique [0002] The hotspot picture is a picture embedded in the base map. The hotspot picture has many application fields, for example, the hotspot picture of the map in the high-definition GIS (Geographic Information System, Geographic Information System) field of the splicing wall. [0003] The implementation method of loading massive GIS hotspot pictures on the video wall is generally as follows: [0004] A1: The control server preprocesses the map. The preprocessing is as follows: generate several pictures of the same size according to different scales, and then display them on the video wall in a distributed display mode. In this step, each scale corresponds to a large image, and the preprocessing is to preprocess this large image, divide the large image into several sma...
