Creating animated gif from latex src blocks |

Hello,
I would like to create an animated gif for a latex src block.
Here to fix ideas such a block :
<====================================================================================>
#+header: :file test4.gif
#+header: :exports results
#+header: :results output silent graphics file
#+header: :imagemagick yes :iminoptions -density 600 -delay 8 -loop 0
-background white -alpha remove
#+header: :fit yes :noweb yes :headers '("\\usepackage{tikz}")
#+begin_src latex
\foreach \angle in {0,10,...,360}
{
\begin{tikzpicture}
% fill circle and plot
\fill[blue!50] (-1,0) arc (0:\angle:1) -- (-2,0) -- cycle;
\fill[blue!50] plot[smooth,domain=0:\angle] (pi/180*\x,{sin(\x)}) |- (0,0);
% draw connection
\draw (-2,0) +(\angle:1) circle (2pt) -- (pi/180*\angle,{sin(\angle)})
circle (2pt);
% draw axes an ticks
\draw (-3.5,0) -- (7,0);
\foreach \deg in {90, 180, 270, 360}
\draw (pi/180*\deg,2pt) -- (pi/180*\deg,-2pt) node[below] {$\deg^\circ$};
\draw (0,-1.2) -- (0,1.2);
\foreach \y in {-1,-0.5,0.5,1}
\draw (2pt,\y) -- (-2pt,\y) node[left] {$\y$};
% draw plot and circle outline
\draw plot[smooth,domain=0:360] (pi/180*\x,{sin(\x)});
\draw (-2,0) circle (1);
\end{tikzpicture}
}
#+end_src
<====================================================================================>
grabbed here :
https://tex.stackexchange.com/questions/291627/draw-an-animated-gif-of-trigonometry-function
When hitting [C-c C-c], it does produce a gif, but which cannot be
animated.
I downloaded another animated gif on internet which works properly
within emacs, so the issue comes most probably from the latex to pdf
generation.
I noticed that the latex header used is
<==============================================================>
\documentclass{article}
\usepackage[usenames]{color}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage{longtable}
\usepackage{wrapfig}
\usepackage{rotating}
\usepackage[normalem]{ulem}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{capt-of}
\pagestyle{empty} % do not remove
% The settings below are copied from fullpage.sty
\setlength{\textwidth}{\paperwidth}
\addtolength{\textwidth}{-3cm}
\setlength{\oddsidemargin}{1.5cm}
\addtolength{\oddsidemargin}{-2.54cm}
\setlength{\evensidemargin}{\oddsidemargin}
\setlength{\textheight}{\paperheight}
\addtolength{\textheight}{-\headheight}
\addtolength{\textheight}{-\headsep}
\addtolength{\textheight}{-\footskip}
\addtolength{\textheight}{-3cm}
\setlength{\topmargin}{1.5cm}
\addtolength{\topmargin}{-2.54cm}
\usepackage[active, tightpage]{preview}
<==============================================================>
which is different from the latex header used in tex.stackexchange page
:
<========================================>
\documentclass[tikz]{standalone}
\usepackage{tikz}
<========================================>
I replaced the default header provided by emacs with this very one and
it worked. Is it possible to modify the latex header depending on the
export image format ?
Regards
