Converting TikZ / SVG into PNG

\documentclass[varwidth]{standalone}
\usepackage{graphicx, import ,xcolor, tikz}

\begin{document}
\begin{tikzpicture}
  \draw [step=0.5] (-1.4,-1.4) grid (1.4,1.4);
\end{tikzpicture}

\begin{figure}
    \centering
    \import{}{diagram.pdf_tex}  % SVG exported from Inkscape
\end{figure}
\end{document}

Convert into PDF :

pdflatex -output-dir=out content.tex && mv out/content.pdf content.pdf

Convert into PNG (using ImageMagik) :

convert -density 300 convert.pdf -quality 90 file.png

Issue : Non authorized

Solution : changing the policy.xml of ImageMagick (/etc/ImageMagick-6/policy.xml).
