Graphics, Figures & Tables ⇒ Inserted JPEG File not displayed in Output

[Rahul]

Hi,

I'm using a simple code.

Code: Select all

\documentclass[12pt,journal,compsoc]{IEEEtran}
\usepackage{alltt}
\usepackage{amssymb}
\usepackage{amsfonts}
\usepackage{mathtools}
\usepackage{array}
\usepackage{amsmath}

\begin{document}

\begin{figure}[ht]
  \centering
  \includegraphics[width=\linewidth]{image1}
  \caption{my comments}
  \label{referenceForText}
\end{figure}
\end{document}

There are some questions I have :

1. Should the image lie in the folder we are having the source file?
2. And when I am using I am getting this error.
   

   Code: Select all

   Overfull \hbox (19.95824pt too wide) in paragraph at lines 96--123
    [][] 
   
   Overfull \hbox (18.2944pt too wide) in paragraph at lines 129--150
    [][] 
   
   Underfull \hbox (badness 10000) in paragraph at lines 153--157
   
   [3]
   Overfull \hbox (181.7277pt too wide) detected at line 223
   \OML/cmm/m/it/12 R[] \OT1/cmr/m/n/12 = [] []
   ! Undefined control sequence.
   l.229   \includegraphics
                           
   ? 
   

Is the image too large? The source file divides the text in two columns.

The example you gave does not have over 100 lines of code, so i can't tell if pictures are too large. Have a look at those lines in your input file to check it out yourself. A wild guess tells me, that those might be equations.

To include graphics into your document, you need to load graphicx. The jpeg-files need to be in the same folder as your main tex-document. You can put them in a subfolder tough, but you have to tell LaTeX about it:

Code: Select all

\includegraphics{NameOfTheSubfolder/NameOfFileWithoutEnding}

I strongly advise you to read some introductory material. You can also check out the featured book at the right side of this page.


Please read the captions in the following example to learn something about the linewidth in twocolumn documents.

Code: Select all

\documentclass[12pt,journal,compsoc]{IEEEtran}
\usepackage{graphicx}
\usepackage{blindtext}

\begin{document}
\blindtext[3]

\begin{figure}
  \centering
  \includegraphics[width=\linewidth]{example-image-a}
  \caption{linewidth in a two column document refers 
  to the width of one column}
  \label{referenceForpicA}
\end{figure}

\begin{figure*}
  \centering
  \includegraphics[width=\linewidth]{example-image-b}
  \caption{The starred version puts your pic over both 
  columns, linewidth now refers to the width of both 
  columns and the little space between them.}
  \label{referenceForpicB}
\end{figure*}

\blindtext[3]
