9 patch image draws background color

I have an image containing arrow drawn on white color background. I'm decoding it as follows.

Drawable drawable = context.getResources().getDrawable(R.drawable.arrow);  
Bitmap bm;  
Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight(),     Config.ARGB_8888);  
Canvas canvas = new Canvas(bitmap);   
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());  
drawable.draw(canvas);  
bm = bitmap;

When bitmap 'bm' is drawn on canvas, I can still see white color background. Where as in case of normal png, it works just fine.

Can anybody tell me what is wrong with this image?

The PNG format supports the transparency channel while BMP doesn't. So if you are using a .bmp or .jpeg file as your arrow drawable, you will get a full rectangular copy of it drawn on the canvas. So my advice is to find a .png version of an arrow.
