imageview

I can't seem to get my ImageView to display its source image in its original size. The ImageView looks like this:

   <ImageView 
 android:id="@+id/Logo" 
 android:src="@drawable/logo"
 android:layout_width="wrap_content" 
 android:layout_height="wrap_content"
 >
</ImageView>

The source image is 140 pixels wide, yet on the Nexus One's screen, which is 480 pixels wide it uses up half of the width. Using absolute values in px or dp for the width and height changes nothing. The image also looks very antialiased from the upscaling. Why is this happening and how can I prevent it?
