It gives exactly the precision of the actual pixel data. So if the image is 16-bit float, this will yield (0,014557;0,053680;0,827148) for what is (32;66;235) in RGB. That should be precise enough:) Hi. This sounds promising. Can you please explain what you mean by "the pixel option" ? How can I enter values like this? I would actually prefer 16-bit integer, but float could work too. I would also like to know more about the Pixel option! Sounds very interesting.
