I need to rotate an ImageView by a few degrees. I'm doing this by subclassing ImageView and overloading onDraw()
@Override
protected void onDraw(Canvas canvas) {
canvas.save();
canvas.scale(0.92f,0.92f);
canvas.translate(14, 0);
canvas.rotate(1,0,0);
super.onDraw(canvas);
canvas.restore();
}
The problem is that the image that results shows a bunch of jaggies.
How can I antialias an ImageView that I need to rotate in order to eliminate jaggies? Is there a better way to do this?
