The source code is available -- essentially it stretches contrast in each R, G, B channel separately. If you press Auto and then open as curves, you can see. The end points are, however, a few percent in from the ends, limiting its usefulness in a professional setting. > Its behaviour should be configurable by the user. The point of it is that it "just works". An auto button should not be configured. I think really what you are asking for is a "stretch contrast" filter that has configurable black and white points. Note that you can already configure the black and white points in levels using the eye dropper. > The user interface for this functionality could be accessed by the user double clicking the "Auto" button. That would be a "no" :-) There aren't any other buttons that behave differently when you double-click on them (and actually for good reason, as no-one would ever guess it, and because it would mean every button would have to wait to see whether the user double-clicked before doing anything, giving a UI feeling of slowness. I'm supportive of being able to set the levels/auto clipping percentage, perhaps in the Colours/Map/Stretch Contrast GEGL filter. Liam -- Liam R. E.
