# Why includegraphics within textpos does not appear on PDF

I have a poster in which I need to place several logos in pdf format. For this I use the textpos package together with includegraphics. Why do these logos disappear on the pdf file after the tex is pdflatexed?

\documentclass[11pt, oneside, A4paper,final,leqno]{article}
\usepackage{amsmath}

\newcommand\myrule{$\;$\rule{1.362cm}{.4pt}}
\newcommand{\qrule}{\gray~\rule{3.129362cm}{.4pt}}
\usepackage{enumerate}

\usepackage{tikz}

\newcommand*\ncircled[1]{\tikz[baseline=(char.base)]{
\node[shape=circle,draw,inner sep=1.93812pt, color=blue] (char) {#1};}}

\usepackage[left=1.48075cm,top=2.019012473cm,right=2.1919cm,bottom=2.185391469cm,bindingoffset=0.05cm]{geometry}

\usepackage[absolute,overlay]{textpos}

\begin{document}

\huge

\begin{center}
\scalebox{.672597892}{\bf Vietnam Mathematical Competition}
\end{center}

\begin{textblock}{20.5}(10.2, 1.)
\includegraphics[scale=1.2]{pdflogo}
\end{textblock}

\end{document}

• If I replace your pdflogo whith example-image the images appears in the output. Apart fom that: Are you sure that the article documentclass is a good choice for producing a poster? Why not use one of the documentclasses specially dedicated to produce posters that are listed here: How to create posters using LaTeX – leandriis Jan 11 at 9:57
• Also, it should be 'a4paper', not 'A4paper'. – Ian Thompson Jan 11 at 9:58
• Further to the comment by @leandriis, my guess would be that there is white space around the logo. You might need to crop it. – Ian Thompson Jan 11 at 9:59
• I can view all the logos in the internal viewer of Texstudio. But I can not view the logos when open the pdf file using external pdf adobe. – Thumbolt Jan 11 at 10:13

There are several issues with position and scale that seem to be pushing the image off the page

\documentclass[11pt,oneside,a4paper,final,leqno]{article}


I also substituted

\begin{textblock}{20.5}(10.2, 1.)
\includegraphics[scale=1.2]{pdflogo}


with the following, they may not be ideal values but they fit better

\begin{textblock}{10.5}(1.2, 1.)
\includegraphics[scale=1]{pdflogo}


This pulls the image left and into view,
I cant test in adobe but I can see the image mid page in other viewers
