问题描述

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);.
