PIX files are the default format for many of our tools including our primary ray tracer.

You cannot change the format of a .pix file, so that conversion would necessarily occur within the library. We have a few tools that will process a .dpix file, which is a double-precision floating point format, but that's an experiment from 20+ years ago that hasn't been touched in at least half that time. The most important aspect is to just never lose any precision. It should be entirely lossless processing so you can bring data into the library and export always ending up with where you started, so long as the output format has the requisite range. Cheers!
