Android - ImageView scaleType Samples

I found it super frustrating when testing out the different scale types for an ImageView. The Graphical Layout in Eclipse currently does not consistently show an accurate representation of an image in an ImageView when changing the scaleType. The only way to know what the image was going to look like was to run the app and then decide if the current scaleType was what I was looking for.

Here is a table showing samples for all scale types for the ImageView.

scaleType	fill_parent x fill_parent	200dp x 200dp	200dp x 200dp with Overlay
matrix
fitXY
fitStart
fitCenter
fitEnd
center
centerCrop
centerInside

The column labeled "fill_parent x fill_parent" represents the following layout:

 <?xml version="1.0" encoding="utf-8"?>  
 <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   android:layout_width="fill_parent"  
   android:layout_height="fill_parent">  
   <ImageView android:layout_width="fill_parent"  
               android:layout_height="fill_parent"  
               android:src="@drawable/eureka"  
               android:scaleType="matrix">  
   </ImageView>  
 </FrameLayout>  

The column labeled "200dp x 200dp" represents the following layout:

 <?xml version="1.0" encoding="utf-8"?>  
 <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   android:layout_width="fill_parent"  
   android:layout_height="fill_parent">  
   <ImageView android:layout_width="200dp"  
               android:layout_height="200dp"  
               android:layout_gravity="center"  
               android:src="@drawable/eureka"  
               android:scaleType="matrix">  
   </ImageView>  
 </FrameLayout>  

Finally, the column labeled "200dp x 200dp with Overlay" represents the last layout with a 200dp by 200dp rectangle centered and overlaying the ImageView.
