How to convert the figures in ps/pdf obtained from tex to eps so that is mathematical symbols remains intact.
\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{decorations.markings}
\begin{document}
\begin{tikzpicture}[%x=2cm,y=2cm
dot/.style = {circle, fill,
inner sep=.3ex,
}
]
\draw[-latex, thick, draw=black] (0,0)--(1,0) node [right] {$x$};
\draw[-latex, thick, draw=black] (0,0)--(0,1) node [above] {$y$};
\draw[scale=1,red,fill=red] (0, 0) circle (.3ex);
\draw[scale=1] (0, 0) node[anchor=north east]{$O$} ;
\draw[<<-,line width=2,blue] (0,1) -- (1,1) node[right]{$(x_0,y_0)$};
%\draw[middlearrow={stealth reversed},line width=2,blue] (0,4) -- (3,4)
\draw[scale=1,red,fill=red] (1,1) circle (.3ex);
\end{tikzpicture}
\end{document}
Problem 1: Using some online converter (online-convert.com), the comma in $(x_0,y_0)$ is not coming properly. I have attached the jpg of the eps file (tex to ps by texniccenter then ps to eps online).
Problem 2: I want to make the mathematical symbols $(x_0,y_0)$ bigger in size. How it is possible?

pdftops -eps <PDF file>, which should generate a.epswithout problem. – Werner Jan 29 '20 at 06:23ps2epsshould be installed, which you can use from the Command Prompt. – Marijn Jan 29 '20 at 11:51\scalebox{<num>}{<coords>}, where<num>is the scaling factor. For example,\scalebox{2}{$(x_0,y_0)$}would double the size of the entire coordinate object. – Werner Jan 29 '20 at 17:55
