汇编
图:这几天在学习汇编语言
图形操作
于是想起以前用C#画过个小 8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
实现中需要
GDIAPI
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……绘图核心源码:
