[Tex/LaTex] newtxmath \hat{} problem in beamer

beamer

Using the newtxmath package with beamer produces wrong output for the \hat{} command. I don't see the problem in the article mode. Also, using alternative packages such as times cause no problems. I am using TeX Live with kile under Linux Mint 14KDE.

\documentclass[handout,utf8]{beamer}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{newtxtext}
\usepackage{newtxmath}

\begin{document}

\begin{frame}
$\hat{\theta}$
\end{frame}

\end{document}

Any suggestion on how to fix this?

You may use \usefonttheme{professionalfonts} or, equivalently, pass the option [professionalfonts] to beamer:

\documentclass[professionalfonts]{beamer}

so that the Beamer's internals do not rewrite the font schemes used.

You can test with the macro \IfFileExist{filename}{then-do-this}{else-do-this} whether a file filename exists or not and respond accordingly. If the file filename exists, the then-do-this branch is executed, otherwise the else-do-this branch. Replace then-do-this and else-do-this with your own code.

In your new given MWE I would delete thr part to copy the pdf file and change the part to build the thumbnail slide to (supposing you have 4 thumbnails to include):

\IfFileExists{\jobname-copy.pdf}{%
\begin{frame}
  \foreach \i in {1,...,4} {
    \fbox{\includegraphics[width=0.2\linewidth, page=\i] {\jobname-copy.pdf}}
  }
\end{frame}
}{\typeout{No Thumbnails included}}

Now you only need to do (you can put this into a batch file):

pdflatex myslides.tex
pdflatex myslides.tex
cp myslides.pdf myslides-copy.pdf
pdflatex myslides.tex

The thumbnail were only included if the file myslides-copy.pdf exists. If not file myslides.tex compiles without included thumbnails.

Update 2:

The reason for the error message you got

Error: PDF file is damaged - attempting to reconstruct xref table...

is simple: you want to copy the file myslides.pdf you have already opened to compile it. That's not possible. So you have to first compile the presentation to get the frames and to close this file myslides.pdf. Then copy the file myslides.pdf to myslides-copy.pdf to include the thumbnails from myslides-copy.pdf into a new compiled file myslides.pdf.

[Tex/LaTex] Numerical conditional within tikz keys

I am definitely unfamiliar with both beamer and tikz (do not quite get what the \only are supposed to do) but perhaps this could go in the direction you want:

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{chains}
\newcounter{count}

% helper macro:
\long\def\GobToSemiColon #1;{}

\newcommand\myPicture{
\begin{tikzpicture}
  \begin{scope}[start chain = going below]
  \ifnum\value{count}<1 \expandafter\GobToSemiColon\fi
  \ifnum\value{count}>3 \expandafter\GobToSemiColon\fi
  \node[draw, rectangle, on chain] {display only when counter is between
    1 and 3};

  \ifnum\value{count}>-1 \expandafter\GobToSemiColon\fi
  \node[draw, rectangle, on chain] {display only when counter is
    negative}; 

  \ifnum\value{count}<100 \expandafter\GobToSemiColon\fi
  \ifnum\value{count}>200 \expandafter\GobToSemiColon\fi  
  \node[draw, rectangle, on chain] {display only if counter is between
    100 and 200};

  \ifnum\value{count}<3 \expandafter\GobToSemiColon\fi
  \ifnum\value{count}>20 \expandafter\GobToSemiColon\fi
  \node[draw, circle, on chain] {only when counter is in the range 3 to 20};
  \end{scope}
\end{tikzpicture}
}

\begin{document}
\begin{frame}
\only{\setcounter{count}{-3}\myPicture}
\only{\setcounter{count}{105}\myPicture}
\only{\setcounter{count}{39}\myPicture}
\only{\setcounter{count}{2}\myPicture}
\only{\setcounter{count}{5}\myPicture}
\end{frame}
\end{document}
