VC在监测系统中图形刷新问题的研究

采用内存虚拟屏幕改进屏幕显示,通过创建内存设备环境和显示兼容的位图,将图形绘制在与内存设备环境兼容的位图区域中,然后将图形从位图中复制到显示器屏幕上,缩短了显示图形所用的时间,并且不必擦除背景,实现了无闪烁的实时曲线连续显示。

Research on Adopting VC to Solve Graphic Refresh in the Field of Monitor System

Adopt memory virtual screen to improve on the screen display.By Creating the memory device context and display compatible bitmap,draw the graphics in the bitmap field that is compatible with the memory device context,then copy the graphics from the bitmap to the display screen.It cut down the time that used to display the graphic and needn't erase the background.Under the line of it,people can realize the non-flicker and continous real curve display.
