> While looking into the code for PDFBOX-4184 I noticed that we try to get the 
> alpha data in different ways, despite that it is available in the main method 
> when {{image.getRGB()}} is called. So I'm refactoring all this; as a side 
> effect, my 16 bit change in PDFBOX-4184 is no longer needed.
> I'll commit this in two steps; 1) changing the main method and remove the 
> ones that are no longer being used; 2) split the main method in a gray and a 
> color code.
