Just a comment related to negative numbers and practical usage... At ProDigital Software we make Photoshop plug-ins. One set in particular adds lighting effects to images, and we handle any RGB format that Photoshop can deliver to us, including 32 bit floating point.
We specifically had to add code that zeroes any negative values received, which we found were occasionally being delivered in images expressed in the ColorMatch RGB space. To us negative values can't possibly make sense. Put another way, what's blacker than black? Even modern physics doesn't attempt to describe what's inside the event horizon of a black hole. At least not in the same realm as the physics that describe the visible universe. Granted, the code that ensures no negative values can exist wasn't hard to write nor particularly wasteful of resources, but it DOES take a little time. From our perspective, if all color engines were to ensure only positive numbers would be generated (as LittleCMS does) we could have saved our user a little time starting our software every time it's run. I'm not making a hard case against lifting the restriction against emitting negative numbers from LittleCMS transforms, except to say that as a tool/engine we currently rely on the current behavior and if it's changed we'd like an OPTION to keep it working as it does now. Thanks. -Noel ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
