Я создал эту тему после моего предыдущего поста .Я не могу запустить следующий код (написанный @belisarius):
a = Image["path/file.png"]
b = Image@ArrayPad[ImageData@a, {{40, 0}, {40}, {0}}, {1, 1, 1}];
f[image_, angleMult_] := ImageForwardTransformation[image, (
fi = ArcTan[Abs[#[[2]]/(#[[1]] - .5)]];
fi1 = angleMult fi (#[[1]]^2 + #[[2]]^2)/2;
{(1/2 - Sin[fi1] #[[2]] - Cos[fi1]/2 +
Cos[fi1] #[[1]]), -Sin[fi1]/2 + Sin[fi1] #[[1]] +
Cos[fi1] #[[2]]}) &]
t = Table[f[b, x], {x, 0, .2, .02}];
t1 = Reverse@t;
Export["anim.gif", Join[t, t1], "DisplayDurations" -> .15];
Import["anim.gif", "Animation"]
