摘要
分析了随钻地质导向地面监控系统测井曲线绘图过程中屏幕图形闪烁产生的2个原因。提出了采用不进行背景重绘的方法消除背景刷新引起的闪烁现象,采用内存DC绘图消除测井图形刷新造成的屏幕闪烁现象。给出了具体的实现步骤和基于Visual C++6.0平台MFC基础类库的多文档滚动视图结构。该方法已成功运用在随钻地质导向测井评价系统中的实时曲线显示过程中,使得钻井数据传输过程中画面平滑过渡,实现了图形无闪烁连续显示。
Analyzed are the 2 reasons causing screen flicker in the process of logging curves redraw operation for LWD interpretation system. Screen flicker caused by background refresh is eliminated by cancellation of background redraw. Screen flicker caused by logging curves refresh is eliminated by using memory DC plotting. Provided are the detailed realization procedure and multi-document scroll view structure based on Visual C＋＋ 6. 0 and MFC base class library. This technology has been used in real-time curve display successfully, and has made the image transition smoothly in the process of drilling data transmission so as to get the flicker-free rendering of LWD curves.
