摘要
详细介绍了远程屏幕图像的抓取及其在网络上传输过程,并针对相关软件中普遍存在的网络带宽过大、实时性差、占用系统资源过多、稳定性差等问题,侧重在屏幕图像的抓取与位图数据流的压缩、解压缩两方面提出了较为有效的解决方法,并提供了改进与实现的Delphi代码.这对于现有此类相关软件的完善及今后相关软件的研发具有指导与参考价值.
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.
