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.

begin{tikzpicture}

defmytext{$prodlimits_{j=1}^{9} overrightarrow{alpha} rho_1 mathbb{A} T_{3}H_0 dfrac{varrho}{2} eta' sumlimits_{jinmathbb{N}} exists iu int_{0}^{1}$}

tikzset{mynode/.style={anchor=south,inner sep=0}}

node[mynode]{mytext};

node[scope fading=south,opacity=0.4,yscale=-1,mynode]{Παρατηρήσεις};

end{tikzpicture}



begin{turn}{180}

begin{tikzpicture}[rotate=90]

defmytext{$prodlimits_{j=1}^{9} overrightarrow{alpha} rho_1 mathbb{A} T_{3}H_0 dfrac{varrho}{2} eta' sumlimits_{jinmathbb{N}} exists iu int_{0}^{1}$}

node[mynode]{mytext};

node[scope fading=south,opacity=0.4,yscale=-1,mynode]{Παρατηρήσεις};

end{tikzpicture}

end{turn}



end{document}

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

Is any solution?

Ευχαριστώ εκ των προτέρων!

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.

foreach X in {1,...,12}

xdeflstFit{lstFit(X)}

fi}

node[fit=lstFit](fit){};

foreach X [evaluate=X as Y using {int(X-1)}]in {1,...,12}

{pgfmathsetmacro{tmp}{lstMirrors[Y]}

node[scope fading=south,opacity=0.4,yscale=-1,anchor=south] at 

(X.south |- fit.south) {ensuremath{tmp}}; }

end{tikzpicture}

Can one rotate this? Yes, e.g. by packing it into a savebox. I hesitate to put too much effort in this preliminary answer because you may find it unacceptable to use an editor that cannot deal with Greek characters. However, if you are OK with that and give me further feedback on the features you want to have, I will be happy to expand this answer.
