No. But it can't work with 32-bit floating point either and even 16-bit
integer approach is not good. So I am considering RGBAImage API as dumb
and simple and I do not know how it can be improved without growing into
complete interactive image viewing application. I think it is a task for
libraries like gdk-pixbuf to be able to handle complex images sensibly.
Unfortunately many of these middleware libraries (and gtk-pixbuf is an
example) do not provide any added value over libtiff's RGBAImage
functionality, so viewers based on them also have all the limitations of
RGBAImage.

Best regards,
Andrey
