I'm attaching testcase that should pass when running on 16bpp (please note that there is a #isDepth16Image selector which has been created in #126).

Here is the source:

isDepth16Image
    "return true if the image is instance of Depth16Image"
   (self bitsPerPixel == 16) ifTrue:[^ true].  
    ^ false
