Hi Corinna,

I have been busy trying to load your picture but some internals of the
tiff reader doesn't allow for that right now. Hopefully I can fix
soon.

You have to build such image type. Here is how you do it:

typedef bit_aligned_image5_type< 16, 16, 16, 8, 8, cmyka_layout_t
>::type image_t;

You could use a dynamic_image. See the dynamic_image extension.
