Question

I would like to make a GIF animation out of a series of functional shadings. But it seems ImageMagick cannot even handle one shading. Did I miss any option of ImageMagick? Or are there any alternatives?

Story

The PGF manual proposed a beautiful shading

of which an MWE is as follows

\documentclass[tikz]{standalone}
\usetikzlibrary{shadings}
\begin{document}
\tikz\shade[shading=Mandelbrot set](0,0)rectangle(2,2);
\end{document}

Then I found that ImageMagick does not convert the resulting PDF properly. For instance with

convert -density 1440 in.pdf out.gif

it gives

    I like that "glitchy" effect.

    @Clément That is the annoying part! ImageMagick definitely knows functional shading, but it behaves like it is unwilling to deal with it.

  • Yes, I know! I tried other options with gs, with dvi outputs, and get the same (or even worst) results. What makes you think the problem comes from PGF and not from ImageMagick?

  • @Clément It would be nice if "it is PGF's fault and we can find other ways to generate functional shadings". In this manner, even TeX is not really necessary.

    I'm voting to close this question as off-topic because it is related to (problematic) optimization of external script (Ghostscript and ImageMagick)
