I've just been asked to write a minimal working example (MWE), what is that?

Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem.

\usetikzlibrary{fadings} \begin{tikzfadingfrompicture}[name=myfading] \end{tikzfadingfrompicture}

path fading=myfading, fit fading=false, fading transform={shift=(myfadingnode.center)}
