Description

Cloud application virtual frame display method and system based on transparent value Technical Field The invention relates to the field of cloud computing, in particular to a cloud application virtual frame display method and system based on transparent values. Background The development of cloud computing brings about 2 large products, desktop virtualization and application virtualization, and under the credit scene, the application ecology is imperfect, so that the cloud application platform is widely applied, the work of application delivery is simplified, and the burden of enterprises on PC management and operation and maintenance is reduced. The application of the virtualization technology plays a vital role in the field of trafficking and provides an overage for the development of application ecology. The current common cloud application schemes are: 1. RDP-based open source practice FreeRDP, freeRDP is an open source RDP (Remote Desktop Protocol) client and library for remote access to Windows remote desktop services and other RDP servers. The FreeRDP item aims at providing a RDP (remote data processing) implementation with rich functions, safety and high efficiency and supporting various operating systems and platforms, but the expansion of a protocol layer is very difficult due to the closed source of a server, and in addition, due to the multi-window image matting scheme of a client, black edges exist in some application frames, and the real-time refreshing of contents is required in a dragging scene, so that the flow is very high in the fast dragging scene, the CPU resource occupation is high, and the experience effect is poor. 2. Based on rdp server proxy scheme, in order to make further optimization (flow, bandwidth, etc.) at protocol layer, a rdp client is implemented at server itself, rdp communication is performed with rdpserver local to server, then rdp server is controlled by controllable data compression or frame rate after intercepting data, similar to a layer of hook is performed at server, but the scheme is limited in protocol layer optimization and cannot be fully autonomous and controllable, so that the rdp scheme can only be used as transition. 3. Compared with the scheme 1, the desktop matting scheme based on the spice protocol has the advantages that spice is replaced by the protocol, and other schemes are similar, such as window management, the scheme can be autonomously controllable on the protocol, but in window management, a multi-window scheme is adopted, and for some applications with shadow frames, black edges exist, and certain defects exist on application compatibility and cannot be solved. 4. The desktop clipping scheme based on the spice protocol is the scheme, although the protocol layer is based on spice, the scheme is refreshed in real time under a window dragging scene, and the scheme has the advantages of large traffic consumption, high cpu resource occupation, and particularly obvious under 2k and 4k scenes along with the improvement of frame rate and image quality. 5. The key to realizing the virtual frame is how to know the irregular area of the virtual frame, how to identify the virtual frame by what method, how to calculate the transparency of the overlapped area of the virtual frame, and how to mix the virtual frame and the client, so that the difficulties need to be overcome, such as marking by specific transparency values, calculating the inverse of the overlapped area, calculating the irregular area, and the like. Disclosure of Invention Aiming at the problems in the prior art, the invention provides the cloud application virtual frame display method and the cloud application virtual frame display system based on the transparent value, which reduce the consumption of resources of a server under a dragging scene, greatly improve the experience effect of the application and achieve the effect comparable to that of a physical pc. In order to solve the technical problems, the invention adopts the following technical scheme: The cloud application virtual frame display method based on the transparent value is applied to a cloud application system comprising a server side and a client side, and comprises the following steps: After the server side identifies that the client side opens the application, the transparency and the region information of the opened application are extracted, wherein the region information comprises a non-transparent region, a transparent region and a frame region, the interface region of the opened application is the non-transparent region, the region outside the opened application interface is the transparent region, and the frame of the opened application interface is the frame region; The server side sends desktop image data, transparency of the opened application and area information comprising a non-transparent area, a transparent area and a frame area to the client side; And the client mixes the transparency and the desktop image d
