GDI绘制平滑曲线处理问题

Question

你好，请问用GDI绘制出曲线
path.AddCurve( CollectPoints, npoints);
graphics.DrawPath(&Pen, &path);      //绘制平滑曲线画出来的曲线有锯齿，如何处理，使其尽量平滑？谢谢

Answer 1

你这不是gdi+嘛！
是不是你离散的点太少了
用二次曲线拟合试一下，不过要你自己实现离散的点，调用方式和你这个是一样的

Answer 2

设置GDI＋属性，让其反走样处理

Answer 3

graphics.SetSmoothingMode(SmoothingModeHighQuality);  

Answer 4

enum SmoothingMode
{
    SmoothingModeInvalid     = QualityModeInvalid,
    SmoothingModeDefault     = QualityModeDefault,
    SmoothingModeHighSpeed   = QualityModeLow,
    SmoothingModeHighQuality = QualityModeHigh,
    SmoothingModeNone,
    SmoothingModeAntiAlias,
#if (GDIPVER >= 0x0110)
    SmoothingModeAntiAlias8x4 = SmoothingModeAntiAlias,
    SmoothingModeAntiAlias8x8
#endif //(GDIPVER >= 0x0110) 
};

Answer 5

graphics.SetSmoothingMode(SmoothingModeHighQuality);
