圆弧不要用Ellipse画，用Arc函数画 pDC->Arc(int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4);由(x1, y1, x2, y2)确定椭圆外接矩形，(x3, y3, x4, y4)确定圆弧起点与终点(不一定在所要圆弧上，但必须使其与圆心的连线与前确定的椭圆有交点)不行吧 你可以先画一个完整的圆 再覆盖下部分就行了
int x1,int y1,int x2,int y2 );x1 Specifies the logical x-coordinate of the upper-left corner of the ellipse's bounding rectangle.y1 Specifies the logical y-coordinate of the upper-left corner of the ellipse's bounding rectangle.x2 Specifies the logical x-coordinate of the lo...

The reference trajectory is composed by two C3Bezier curves in order to obtain an ellipse like shape with respect to acceleration limits of the mobile robot. The experimental results are presented here to show the efficiency of the proposed approach....
pDC->Rectangle(20,20,220,220) pDC->SelectObject(oldBrush) pDC->SelectObject(oldPen)这个函数写在那个下面,需要用向导添加吗? 相关知识点: 试题来源: 解析 画刷有单色和位图,还有系统默认.上面定义的是单色画刷画圆直接用Ellipse函数就可以了反馈 收藏 ...
