用win32汇编画八卦图
汇编程序的图:
这几天在学习汇编语言的图形操作,于是想起以前用C#画过个小八卦图
半径R自己给……
Graphics g = e.Graphics;
Brush fillWhiteBrush = Brushes.White;
Brush fillBlackBrush = Brushes.Black;
g.FillPie(fillWhiteBrush, 0, 0, r, r, -90, -180);//左半圆
g.FillPie(fillBlackBrush, 0, 0, r, r, 90, -180);//右半圆
g.FillEllipse(fillWhiteBrush, r/4, 0, r / 2, r / 2);//上中型圆
g.FillEllipse(fillBlackBrush, r / 4, r / 2, r / 2, r / 2);//下中型圆
g.FillEllipse(fillBlackBrush, 9*r/20, r/5, r / 20, r / 20);//左小圆
g.FillEllipse(fillWhiteBrush, 9 * r / 20, 7*r/10, r / 20, r / 20);//右小圆
win32汇编的实现中需要调用GDI的API函数来实现……
包括:画笔(CreatePen)、画刷(GetStockObject)、坐标定位(MoveToEx)、画直线(LineTo)、画椭圆(Ellipse)、画扇形(Pie)……
注释已经很清楚了,我就不废话了……
