Visual C++在动态显示过程屏幕闪烁的消除

Elimination of Screen Flicker in Dynamic Displaying with Visual C++

采用 GDI位图及内存设备环境改进屏幕显示 ,通过创建内存设备环境以及与显示兼容的位图 ,先将图形绘制在与内存设备环境兼容的位图中 ,这样显示时就只需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 。

GDI bitmap and memory device context are used to improve screen display.By creating memory device context and compatible bitmap with display,draw the graphics to the bitmap that is compatible with memory device context,and then it is only necessary to copy the graphics from the bitmap to the display screen,which decreases the time to display the graphics and don't need to erase the background,implementing continuous nonflicker process.
