设置透明画刷(2007-04-24 23:56:00)
摘要： 设置透明画刷
我们在VC中画图时，如
CClientDC dc(this); //首先定义DC
dc.Ellipse(point1.x,point1.y,point2.x,point2.y); //画椭圆
画出来的效果就是一块椭圆，但有时我们不需要画刷，只需要一个图形框架就可以了，此时就要设置透明画刷，下面介绍一个设置透明画刷的方法：
CClientDC dc(this);
CBrush *brush=CBrush::FromHandle((HBRUSH)GetStockObject(NULL_BRUSH));
dc.SelectObject(brush);
dc.Ellipse(point1.x,point1.y,point2.x,point2.y); //画椭圆
这样画出来的就不会是一块了。......
