# text with different reflection

Καλημέρα!

I 'm want to have a word (Παρατηρήσεις) like a reflection below of a math text. I want:

• each letter to be bellow of each symbol,
• all the math text in the same line,
• all the image could be rotated.

I tried this, but as you can see the reflections are not good.

\documentclass{article}

\usepackage[english,greek]{babel}
\usepackage[utf8]{inputenc}

\usepackage{tikz}
\usepackage{rotating}

\usepackage{amsmath, amsfonts}

\newcommand{\iu}{{i\mkern1mu}}

\begin{document}

\begin{tikzpicture}
\def\mytext{$\prod\limits_{j=1}^{9} \overrightarrow{\alpha} \rho_1 \mathbb{A} T_{3}H_0 \dfrac{\varrho}{2} \eta' \sum\limits_{j\in\mathbb{N}} \exists \iu \int_{0}^{1}$}
\tikzset{mynode/.style={anchor=south,inner sep=0}}
\node[mynode]{\mytext};
\end{tikzpicture}

\begin{turn}{180}
\begin{tikzpicture}[rotate=90]
\def\mytext{$\prod\limits_{j=1}^{9} \overrightarrow{\alpha} \rho_1 \mathbb{A} T_{3}H_0 \dfrac{\varrho}{2} \eta' \sum\limits_{j\in\mathbb{N}} \exists \iu \int_{0}^{1}$}
\tikzset{mynode/.style={anchor=south,inner sep=0}}
\node[mynode]{\mytext};
\end{tikzpicture}
\end{turn}

\end{document}

I also tried this, but the lines are not good.

\documentclass{article}

\usepackage[english,greek]{babel}
\usepackage[utf8]{inputenc}

\usepackage{tikz}
\usepackage{rotating}

\usepackage{amsmath, amsfonts}

\newcommand{\iu}{{i\mkern1mu}}

\begin{document}

\begin{tikzpicture}
\def\mytext{$\prod\limits_{j=1}^{9}$}
\tikzset{mynode/.style={anchor=south,inner sep=0}}
\node[mynode]{\mytext};
\end{tikzpicture}
%  no empty line here
\begin{tikzpicture}
\def\mytext{$\overrightarrow{\alpha}$}
\tikzset{mynode/.style={anchor=south,inner sep=0}}
\node[mynode]{\mytext};
\end{tikzpicture}
%  no empty line here
\begin{tikzpicture}
\def\mytext{$\rho_1$}
\tikzset{mynode/.style={anchor=south,inner sep=0}}
\node[mynode]{\mytext};
\end{tikzpicture}
%  no empty line here
\begin{tikzpicture}
\def\mytext{$\mathbb{A}$}
\tikzset{mynode/.style={anchor=south,inner sep=0}}
\node[mynode]{\mytext};
\end{tikzpicture}... ...

\end{document}

Is any solution?

Ευχαριστώ εκ των προτέρων!

• (I have studied so much math that I can read the greek in-betweens) Kalimera! Do you want to mirror the letters individually like bd/pq or rotate the whole text? – Huang_d Dec 10 '18 at 8:24
• When you are saying "each letter to be below of each symbol", what precisely is a symbol? Is \rho_1 one symbol or two? Likewise is \prod\limits_{j=1}^{9} one symbol or many? – user121799 Dec 10 '18 at 8:31
• \prod\limits_{j=1}^{9} = Π *** \overrightarrow{\alpha} = α *** \rho_1 = ρ *** \mathbb{A} = α *** T_{3} = Τ *** H_0 = η *** \dfrac{\varrho}{2} = ρ *** \eta' = ή *** \sum\limits_{j\in\mathbb{N}} = σ *** \exists = ε *** \iu =ι *** \int_{0}^{1} = ς – Kώστας Κούδας Dec 10 '18 at 10:47

This may not yet be the answer you are hoping for, but perhaps a first step towards such an answer. First of all, my editor does not deal with the Greek letters. So I produced them in the LaTeX way. (Of course, I could switch to another editor, but this would mean to exclude everyone whose editor has the same problem from being able to copy this answer, something I do not want to do.) Then I guess one has to decompose the formula into atoms. (I do not know if one can do that with decorations.text.) And then a loop over the atoms allows one to attach the mirrors.

\documentclass{article}
\usepackage{amsmath, amsfonts}
\newcommand{\iu}{{i\mkern1mu}}
\usepackage{tikz}
\def\lstMirrors{{"\Pi","\alpha","\rho","\alpha","\eta","\rho","\eta","\sigma","\varepsilon","\iota","\zeta","\zeta"}}

$\tikzmarknode{1}{\prod\limits_{j=1}^{9}} \tikzmarknode{2}{\overrightarrow{\alpha}} \tikzmarknode{3}{\rho_1} \tikzmarknode{4}{\mathbb{A}} \tikzmarknode{5}{T_{3}} \tikzmarknode{6}{H_0} \tikzmarknode{7}{\dfrac{\varrho}{2}} \tikzmarknode{8}{\eta'} \tikzmarknode{9}{\sum\limits_{j\in\mathbb{N}}} \tikzmarknode{10}{\exists} \tikzmarknode{11}{\iu} \tikzmarknode{12}{\int_{0}^{1}}$
\begin{tikzpicture}[overlay,remember picture]
\foreach \X in {1,...,12}
{\ifnum\X=1
\xdef\lstFit{(\X)}
\else
\xdef\lstFit{\lstFit(\X)}
\fi}
\node[fit=\lstFit](fit){};
\foreach \X [evaluate=\X as \Y using {int(\X-1)}]in {1,...,12}
{\pgfmathsetmacro{\tmp}{\lstMirrors[\Y]}
