Can anyone one explain why, what seems to me, rgb, is said to be rna(or point to a url), and why a negative color value exists, 0 is none, negative makes no real sense. With limited knowledge, the alpha layers of png seems 'logical', but it is limited understanding of ther concept of svg. > > With any property where you go outside of the soft limits, there's the > chance that things will work strangely, to me that is sort of the > point of the hard/soft limits, allowing those who know what they're > doing to bend the rules a bit. > > On Tue, Dec 14, 2010 at 3:30 PM, Roger Wickes From IPhone > <[email protected]> wrote: >> There's actual pixel data which is 0-1.0 for rgba.
