Button + image - any way to specify width/height of image?
<p>I defined a button with an image:</p>

<pre><code>&lt;Button
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="test"
  android:drawableTop="@drawable/foo" /&gt;
</code></pre>

<p>Is there a way to specify the width and height, in dip, of the drawable being used? The rules for how the drawable scales aren't clear to me.</p>

<p>Thanks</p>
