我试着画一个旋转的位图与抗混打开，但它仍然有别名，它的不顺利，任何帮助？

我做如下：

 最终涂料P =新的油漆（Paint.ANTI_ALIAS_FLAG）;
p.setAntiAlias​​（真正的）;
canvas.rotate（-mValues​​ [0]）;
canvas.drawBitmap（罗盘，-compass.getWidth（）/ 2，-compass.getHeight（）/ 2，p）的;
 

解决方案

Paint.setAntiAlias​​（）是文本。

您想要 p.setFilterBitmap（真）;

I tried to paint a rotated bitmap with anti alias turned on, but it still has alias and it's not smooth, any help?

I did as following:

final Paint p = new Paint(Paint.ANTI_ALIAS_FLAG);
p.setAntiAlias(true);
canvas.rotate(-mValues[0]);
canvas.drawBitmap(compass, -compass.getWidth()/2,-compass.getHeight()/2,p);

解决方案

Paint.setAntiAlias() is for text.

You want p.setFilterBitmap(true);.
