Yeah, basically, Qt is completely ignorant of color spaces. If you have some sort of really weird display color space other than sRGB, you'll need to worry about that yourself. Most people draw images in "basically sRGB" without knowing it isn't really linear, so if you draw sRGB, you will almost always be consistent with other applications. (Excepting something like Nuke where a user has explicit control over the color space of a viewer. Then the user might explicitly choose Rec.709 or whatever for display.) _______________________________________________ Oiio-dev mailing list [email protected] http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
