[Tex/LaTex] How to insert two logos in beamer poster

beamerposterstikz-pgf

I want to add two logo in my poster one at top left and one at top right.
here is an example, I have used tikz package. To compile this code, you have to upload "confposter" file

 \documentclass[final]{beamer}
\usepackage{tikz}
\usepackage[scale=1.15]{beamerposter} % Use the beamerposter package for laying out the poster

\usetheme{confposter} % Use the confposter theme supplied with this template

\setbeamercolor{block title}{fg=ngreen,bg=white} % Colors of the block titles
\setbeamercolor{block body}{fg=black,bg=white} % Colors of the body of blocks
\setbeamercolor{block alerted title}{fg=white,bg=dblue!70} % Colors of the highlighted block titles
\setbeamercolor{block alerted body}{fg=black,bg=dblue!10} % Colors of the body of highlighted blocks
% Many more colors are available for use in beamerthemeconfposter.sty

%-----------------------------------------------------------
% Define the column widths and overall poster size
% To set effective sepwid, onecolwid and twocolwid values, first choose how many columns you want and how much separation you want between columns
% In this template, the separation width chosen is 0.024 of the paper width and a 4-column layout
% onecolwid should therefore be (1-(# of columns+1)*sepwid)/# of columns e.g. (1-(4+1)*0.024)/4 = 0.22
% Set twocolwid to be (2*onecolwid)+sepwid = 0.464
% Set threecolwid to be (3*onecolwid)+2*sepwid = 0.708

\newlength{\sepwid}
\newlength{\onecolwid}
\newlength{\twocolwid}
\newlength{\threecolwid}
\setlength{\paperwidth}{48in} % A0 width: 46.8in
\setlength{\paperheight}{36in} % A0 height: 33.1in
\setlength{\sepwid}{0.024\paperwidth} % Separation width (white space) between columns
\setlength{\onecolwid}{0.22\paperwidth} % Width of one column
\setlength{\twocolwid}{0.464\paperwidth} % Width of two columns
\setlength{\threecolwid}{0.708\paperwidth} % Width of three columns
\setlength{\topmargin}{-0.5in} % Reduce the top margin size
%-----------------------------------------------------------

\usepackage{graphicx}  % Required for including images

\usepackage{booktabs} % Top and bottom rules for tables

%----------------------------------------------------------------------------------------
%   TITLE SECTION 
%----------------------------------------------------------------------------------------
\title{TitleTitleTitleTitleTitleTitleTitleTitleTitleTitleTitleTitleTitle} % Poster title

\author{xxxxx, xxxxx, xxx} % Author(s)

\institute{ Department of xxxxxxxxx,xxxxxxxxxxxxxxxx} % Institution(s)

%----------------------------------------------------------------------------------------

\begin{document}
 \addtobeamertemplate{headline}{} 
 {\begin{tikzpicture}[remember picture, overlay]
      \node [anchor=north east, inner sep=3cm, yshift=-2cm] at (current page.north east)
      {\includegraphics[width=9 cm, height=9cm]{logo1}};
   \end{tikzpicture}}
   {\begin{tikzpicture}[remember picture, overlay]
      \node [anchor=north west, inner sep=3cm, yshift=-4cm] at (current page.north west)
      {\includegraphics[width=10 cm, height=10cm]{example-image-b}};
   \end{tikzpicture}}
%\setbeamertemplate{headline} { \includegraphics[height=2cm]{images/logo} \hfill \includegraphics[height=2cm]{example-image-a}}
\addtobeamertemplate{block end}{}{\vspace*{2ex}} % White space under blocks
\addtobeamertemplate{block alerted end}{}{\vspace*{2ex}} % White space under highlighted (alert) blocks

\setlength{\belowcaptionskip}{2ex} % White space under figures
\setlength\belowdisplayshortskip{2ex} % White space under equations

\begin{frame}[t] % The whole poster is enclosed in one beamer frame
\end{frame}
\end{document}

You can also use following : Please add this in the preamble.

 \usepackage{tikz}

Then, in the body of your document (right after \begin{document}) add the following:

%-----------LOGO ADDED TO NORTH EAST----------------%
\addtobeamertemplate{headline}{} 
{\begin{tikzpicture}[remember picture, overlay]
     \node [anchor=north east, inner sep=6.5cm]  at (current page.north east)
     {\includegraphics[height=5cm]{NSERG.png}};
  \end{tikzpicture}}
%-------END LOGO ADDED TO NORTH EAST----------------%

%-----------LOGO ADDED TO NORTH WEST----------------%
\addtobeamertemplate{headline}{} 
{\begin{tikzpicture}[remember picture, overlay]
     \node [anchor=north west, inner sep=6.5cm]  at (current page.north west)
     {\includegraphics[height=5cm]{THALES_RT.jpg}};
  \end{tikzpicture}}
 %-------END LOGO ADDED TO NORTH WEST----------------%

Here inner sep specifies de diagonal distance to the top right corner.

Please see below example. Hope this would help.

[Tex/LaTex] Rotate a node but not its content: the case of the ellipse decoration

The source of the difficulty is that ellipses are constructed in a particular way in TikZ. They are paths that start from the x-axis and proceed counter-clockwise around their centre. The vast majority of the time, the exact parametrisation doesn't matter. You appear to have found the one situation where it does!

In the actual question, you only want to be able to mirror the ellipse, and so draw it starting from the negative x-axis (the title of the question suggests a more flexible approach). That's actually not too hard since we can exploit the symmetry of the ellipse. The key is to provide it with a negative x-radius, since then it will start from the negative x-axis (and proceed clockwise, but we could correct for that by negating the y-radius as well). To do this, we interrupt the call from the node shape to the drawing command and flip the sign of the x-radius. The simplest way to do this is to redefine the \pgfpathellipse macro to do the negation and then call the original macro. The following code does this.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations,shapes,decorations.markings}
\makeatletter
\let\origpgfpathellipse=\pgfpathellipse
\def\revpgfpathellipse#1#2#3{%
  #2%
  \pgf@xa=-\pgf@x
  \origpgfpathellipse{#1}{\pgfqpoint{\pgf@xa}{0pt}}{#3}}
\makeatother

\tikzset{
  reversed ellipse/.style={
    ellipse,
    reverse the ellipse%
  },
  reverse the ellipse/.code={
    \let\pgfpathellipse=\revpgfpathellipse
  }
}
\begin{document}
\begin{tikzpicture}
\node[ellipse,
  draw,
  postaction={
    decorate,
    decoration={
      markings,
      mark=at position 1 with {
        \arrow[line width=5pt,blue]{>}
      }
    }
  }
] at (0,0) {hello world};

\node[reversed ellipse,
  draw,
  postaction={
    decorate,
    decoration={
      markings,
      mark=at position 1 with {
        \arrow[line width=5pt,blue]{>}
      }
    }
  }
] at (0,-2) {hello world};
\end{tikzpicture}

\end{document}

Here's the result:

rotated ellipse

(the arrow got clipped, but you can see where it lies)

[Tex/LaTex] Two logos in beamer after certain frame

Let's reuse the code given in an answer to a similar question of yours.

Put the following into the document preamble:

\usepackage{ifthen}
\newboolean{cern}
\setboolean{cern}{false}
\logo{%
  \makebox[\paperwidth-5pt]{%
    \ifthenelse{\boolean{cern}}{%
      \includegraphics[width=1cm,keepaspectratio]{cern_logo_white.jpg}%
    }{}%
    \hfill\includegraphics[width=1cm,keepaspectratio]{ntua-logo.jpg}%
  }%
}

Before you start the first frame telling about your work done at both institutions, insert:

\setboolean{cern}{true}
