CFA = Color Filter Array :-)
As to test it, I use CFA that should create a pgm file for the image.
You open it in an image viewer, it should represent the image
(shape-wise). So yes you should expect a similar thing as with the CR2
file :-)

And a little not about the code style: curly braces are not optional. 
(I need to formalize the coding style a bit and actually make it
consistent, but that one rule is)
