Joao, could you (shortly) outline what kind of functions you could benefit from using libtiff directly, rather than PIL (which uses raw python for this, as I understand). Maybe you even show us a short example. Another reason why I ask, is that I read that libtiff has functions using memory mapping. So far, I have considered TIF a rather inappropriate format for large (multi-dimensional) data because it's not compatible to the mem-map operations I can do using numpy. (i.e. I always have to read everything sequentially from the start)
