Actually there is no ambiguity with channel 1 (channel byte 0). But in general for channel n its important to know if this is 0-based or 1-based. Given that the target audience for users is accustomed to a 1-based notation, that is what the spec should use. And given that the target audience for implementors will assume a 0-based notation, the convention should be explicitly called out otherwise they will get it wrong. -- Chris Lilley Technical Director, Interaction Domain W3C Graphics Activity Lead, Fonts Activity Lead Co-Chair, W3C Hypertext CG Member, CSS, WebFonts, SVG Working Groups
