Using Win32 to assemble and draw gossip charts

Diagram of the Assembler program:

These days in the study of assembly language graphics operation, so think of the previous use of C # painted a small gossip map

Radius r own to ...

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

The implementation of the Win32 Assembly needs to invoke GDI's API functions to implement ...

Includes: Brushes (createpen), brushes (getstockobject), coordinate positioning (MOVETOEX), drawing straight lines (LineTo), drawing ellipses (Ellipse), painting pie (PIE) ...

The note is already clear, I will not nonsense ...
