# 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}
\begin{document}
\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 Feb 24 '16 at 15:28
• @Clément That is the annoying part! ImageMagick definitely knows functional shading, but it behaves like it is unwilling to deal with it. – Symbol 1 Feb 24 '16 at 15:31
• 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 Feb 24 '16 at 15:34
• @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. – Symbol 1 Feb 24 '16 at 15:50
• I'm voting to close this question as off-topic because it is related to (problematic) optimization of external script (Ghostscript and ImageMagick) – Symbol 1 Mar 21 '17 at 20:18
