Hello public-tt, I'm pleased to note that all colors are specified in the sRGB color space. Does TT AF DFXP express any conformance requirement regarding the fidelity of the colors when converting to and from DFXP? I am thinking not only of chrominance and white-point adaptation effects - which should be minimal for modern equipment given that sRGB uses the 709 phosphor chromaticities - but more for differing assumptions on headroom footroom, allowed colors, and corrections for flare, scene brightness, surround and other viewing condition effects. There is a useful discussion at http://www.srgb.com/srgb709compatibility.html How are sRGB and ITU-R BT.709-2 compatible? Basically I am wondering how much guidance should be given in this area such that reliable interchange between differing systems can be achieved. -- Chris Lilley mailto:chris@w3.org Interaction Domain Leader Co-Chair, W3C SVG Working Group W3C Graphics Activity Lead Co-Chair, W3C Hypertext CG
