matrix.Scale(2,1);
path.Transform(&matrix);
Region pathRegion(&path);

if (pathRegion.IsVisible(testPoint,&graphics)) {return;}
SolidBrush brush(Color(255,0,0,0));
graphics.FillEllipse(&brush,testPoint.X - 4,testPoint.Y - 4,8,8);
}
// CGDIplusDemoView 绘制
void CGDIplusDemoView::OnDraw(CDC *pDC) {

这是MFC中的CGDIplusDemoView.cpp中的两个函数，如何才能将OnMouseMove中的代码实现到输出界面上啊？？
