Inconsistent scaling of images on Android for Android: scaleType = "fitCenter"

Question

I would like to display an image with a frame. The solution below is great for some images, but not for others.

So far, I believe that it works great for small images, but not for large ones.

With a smaller image, the solution displays the image beautifully with a 2-pixel border. With a large pattern, the background is too wide in height.

I tested this with an image that I manually scaled from 2000 * 400 to 200 * 40. Thus, it was the same image, only preliminary.

Any idea why large photos won't scale the same as small ones?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:background="#ffffff"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical"
              android:gravity="center" >

    <ImageView
            android:id="@+id/testimage"
            android:background="#000000"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/testimage2"
            android:padding="2dip"
            android:scaleType="fitCenter"
            />
</LinearLayout>
