摘要
本文利用VGA上的剩余videobuffer实现图形存储,代替库函数putimage()和getimage(),既可节省宝贵的CPU的内存空间,同时大幅度提高图形的显示速度,最后给出C++实例,并利用库管理将其添加到库函数中,令后可以象调用库函数getimage()和putimage()那样直接调用saveimage()和restoreimage()。
The Way of graphics storage in VGA by spare wideo buffer which instead of using putimage() and getimage () can save memory space and increase the speed of graphics display. The example of wtilizing database-manage add to database - function to transfer directly saveimage () and restoreimage () as getimage () and putimage () is given in this paer.
