How can I export an animated image

Georges Sardin, retired
Posted 5 years ago

I have this:

Clear [r];
r[t_] := 5 + Sin[10 t];
curves = ParametricPlot[r[t] {Cos[t], Sin[t]}, {t, 0, 2 Pi}];
Animate[Show[curves, 
  Graphics[{PointSize[0.03], Point[r[t] {Cos[t], Sin[t]}]}]], {t, 0, 
  2 Pi}]

How can I export the resulting animated image? Thank you.

Thank you.

You can export Animate directly. If you want to keep controls:

Clear[r];
r[t_]:=5+Sin[10 t];
curves=ParametricPlot[r[t] {Cos[t],Sin[t]},{t,0,2 Pi}];

anim=Animate[Show[curves,
Graphics[{PointSize[0.03],Point[r[t] {Cos[t],Sin[t]}]}]],{t,0,2 Pi}];

Export["anim.gif",anim,AnimationRepetitions->Infinity]

Rohit,

If you don't mind could you tell me what to do for the point not to stop running on the gif picture. And also if it is possible to get the command bar also on the gif picture. I am 80 years old and I started learning mathematica.

Hi Georges,

For endless looping use the "AnimationRepetitions" option

Export["animation.gif", frames, "AnimationRepetitions" -> Infinity]

I don't know of a way to include the Animate controls in the export.

That is awesome! If you have not, I suggest reading Stephen Wolfram's An Elementary Introduction to the Wolfram Language. It is available free online.

Georges,

One way

frames = Table[
   Show[curves, 
    Graphics[{PointSize[0.03], Point[r[t] {Cos[t], Sin[t]}]}]], {t, 0,2 Pi, Pi/36}];

Export["animation.gif", frames]
