I'm using the below Latex code to draw a tikzpicture
\documentclass[convert={density=300,size=1080x800,outext=.png},tikz, border=1cm]{standalone}
\usepackage{{xcolor}}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}
\draw node[draw, fill={{rgb:black,1;white,5}}, minimum size=4cm,line width=0.1cm,font=\fontsize{100}{100}\selectfont, label={[yshift=-6cm,style={font=\fontsize{100}{100} } ] {$x_9$} } ] at (25, 20) {1};
\draw [line width=0.1cm](25,22.0) -- (25,24.0);
\draw [line width=0.12cm] (25,25.0) circle (1);
\draw [line width=0.12cm](25,24.0) -- (25,26.0);
\draw [line width=0.12cm](24,25.0) -- (26,25.0);
\draw [arrows={-Triangle[angle=90:0.5cm,black,fill=black,line width=0.1cm]}](26,25.0) -- (25.9999,25.0);
\end{tikzpicture}
\end{document}
The file is compiled with pdflatex -shell-escape file.tex
and produces the below png.
Although it can't be seen here, the png has a transparent background ( you can see it with only viewing the image link). I want it to have a white background directly instead of converting with an additional external tool.
How can we have a white background or any color at once?
