Question

求计算机图形学画扇形全部代码？

Answer 1

void CDrawtest1View::OnMouseMove(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
if (m_bDraw)
{
CClientDC dc(this);
dc.SetROP2(R2_COPYPEN);
CPen pen(PS_SOLID,1,RGB(255,0,0));
CPen *pOldPen = dc.SelectObject(&pen);

dc.MoveTo(m_ptStart);
dc.LineTo(m_ptEnd);
dc.LineTo(point);
m_ptEnd = point;
dc.SelectObject(pOldPen);
}
CView::OnMouseMove(nFlags, point);
}
全部太多垃圾。关键部分作参考吧。
