Can the RGBA interface work with the 24-bit float sample type to get a preview?

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.

Well, I understand you completely.

Nevertheless such a middleware library is a realy missed. So I hoped for it in RGBA, and, as Bob pointed out, a bit blindly.

Well, creating such a library took me quite some time and it is still not complete. So I can understand why it is not in gtk-pixbuf and osX. At least in Panther most of my tiff's are plainly rejected in the Finder, the same for KDE and Gnome. Do'nt know about Windows.
