What do you mean by 'translators'? If you mean 'image import/export'
than yes, the design can be improved, and we are currently working on
it. If you mean 'adding functions that transform one image into
another', the answer is: just add a new function template. Functions
could be organized into objects to simplify the creation of operator
chains. However, I'm currently not doing this in C++ but leave it to
Python (as I said, VIGRA has a Python interface that's not yet
beenpublicly released ) were the capability comes for free.
