怎么修改GDI+FillEllipse的圆中心点从左下角变成圆心
如何修改GDI+FillEllipse的圆中心点从左上角变成圆心
graphics.FillEllipse(&SolidBrush(Color(155,0,0,0)),x , y , w, h);
------解决方案--------------------
x
Type: System::Int32
The x-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse.
y
Type: System::Int32
The y-coordinate of the upper-left corner of the bounding rectangle that defines the ellipse.
width
Type: System::Int32
Width of the bounding rectangle that defines the ellipse.
height
Type: System::Int32
Height of the bounding rectangle that defines the ellipse.
系统设定如此的行为，不过你可以改用路径来绘制，或者真接绘制曲线
