title: Draw smoothly scaled bitmaps on Canvas
body: <p>This is how I draw <code>Bitmap</code> on <code>Canvas</code> in my Android app:</p>
  
  <pre><code>canvas.save();
  canvas.scale(scale, scale, x, y);
  canvas.drawBitmap(bitmap, x, y, null);
  canvas.restore();
  </code></pre>
  
  <p>However the <code>Bitmap</code> is not scaled smoothly, no anti-aliasing is performed. How can I enable anti-aliasing?</p>
