Out of gamut values are not garbage, but can occur both as intermediate/temporary values - in operations like unsharp mask, as well as for HDR[1] and if the RGB data originates in a color space with a larger gamut than the one currently used. If any operation, or an application like GIMP, requests the data with an 8bit or 16bit representation the data is clamped then. 1: http://en.wikipedia.org/wiki/High-dynamic-range_imaging /pippin _______________________________________________ gegl-developer-list mailing list List address: gegl-developer-list@xxxxxxxxx List membership: https://mail.gnome.org/mailman/listinfo/gegl-developer-list
