Drawing rotated bitmap with anti alias

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);
Solution

  • Paint.setAntiAlias() is for text.

    You want p.setFilterBitmap(true);.
