[Tex/LaTex] Rotate a large image and its caption

floatsrotating

I rotated a figure with landscape but the caption did not rotate as the figure. I would like the caption to be oriented like the figure. Thank you. PS: I use PDFlatex to compile the document.

\documentclass[twoside,b5paper,12pt,fleqn]{psd_thesis}
\usepackage{amsmath,amssymb,amsfonts}           \usepackage[T1]{fontenc}
\usepackage{newtxmath,newtxtext}                
\usepackage{rotating}
\usepackage{pdflscape}
\usepackage{array}

\begin{document}

\begin{landscape}
\begin{sidewaysfigure}
\centering
\includegraphics[width=0.48\textwidth, width=200mm, angle=90]{IM_corr.jpg}
\caption{Intensity measure correlation}
\label{fig:IMs matrix correlation}
\end{sidewaysfigure}
\end{landscape}%}

\end{document}

The psd_thesis.cls is reported below:

Best Answer

You have mess of rotation ... you should simply do the following:

\documentclass[twoside,b5paper,12pt,fleqn]{book}
\usepackage[T1]{fontenc}
\usepackage{rotating}
\usepackage{graphicx} 

\usepackage{showframe}

\begin{document}

    \begin{sidewaysfigure}
\centering
\includegraphics[width=0.9\textheight,height=0.5\textwidth]{example-image}
\caption{Intensity measure correlation}
\label{fig:IMs matrix correlation}
    \end{sidewaysfigure}

\end{document}

Edit: Some remarks about your MWE:

  • please in preamble load only relevant packages, all others had to be omitted
  • for images use example-image from graphicx package. It is available to all who like to help you (we haven't your actual image)
  • function of landscape and sidevaysfigure are similar: both enable to how page content in portrait orientation, i.e. content encapsulate in it hadn't be rotated again.
  • if you prefer landscape (I newer use it, so I haven't experience with it) than don't use sidewaysfigure inside it.
  • to my experience use of sidewaysfigure is simple and robust, so my proposed solution use it :-)
