| Abstract: | This paper introduces the capture of screen image and its online transmission process in detail, and puts forward comparatively effective solution to too network bandwidth,bad real-time transmission,too much system resources,and poor stability which exist in the relevant software at present. This paper lays particular emphasis on the two aspects of solution: screen image capture,and the compression and decompression of bit map dataflow.In addition,it offers the Delphi codes that improve and realize this method.What this paper probes into will bear very important guidance and reference value to perfection this kind of software and to the research and development of the relevant software in future. |
