Hello, I think there is another problem concerning frozen animation, maybe just a wording problem. I discussed this with several people, but the result was always the same, but from my point of view somehow useless for animation, but maybe I am wrong with this. For 'Freezing animations' (SMIL 2.1, 3.3.5) it is noted: 'If AD is an even multiple of d, i.e. AD = d*i for some positive integer i , and the animation is non-cumulative, f_f(t) = f(d).' There a two remarkable points about this - why only 'some' and not 'any' or 'a' positive integer and why only even multiples, why not odd multiples too? Ok, if odd multiples are excluded by this rule, this means that some integers are only even integers, but then it should be much more precise to write: 'AD = d*2*i for a positive integer i' Of course 'even' can have several meanings, therefore I looked for another interpretation for 'even multiple' in wikipedia and other resources, but all I could find is really: 'AD = d*2*i for a positive integer i'. I cannot see, why to distinguish between odd and even multiples? Is there any reason? This causes another problem for odd multiples, because then the following has to be applied: 'If AD is not an even multiple of the simple duration d, f_f(t) = f_i(t), where i = floor(t/d).' For example with AD=d (odd multiple) we get 1 = floor(d/d) f_f(t=AD) = f_1(t=0) if the animation is repeated (and stopped for example with an end attribute) and an undefined value, if the animation is not repeated. Is this correct? Thanks in advance for a clarification Olaf HoffmannReceived on Friday, 6 April 2007 15:02:07 GMT
