Caption does not appear under a figure

Question

I need to put into my thesis (portrait format) a figure in landscape format. I tried using pdflscape environment but it didn't work for me. Now I am trying to use sidewaysfigure environment. The figure looks good but there is no caption under it. Where is my mistake? And is there any other way to put my figure in landscape format?

My code is:

\documentclass[11pt, a4paper, oneside]{Thesis}

\usepackage{wrapfig}
\usepackage{pdflscape}
\usepackage{rotating}
\usepackage{epstopdf}

\begin{sidewaysfigure}
\centering
   \includegraphics{d:/Thesis/Thesis_InLaTeX/thesis_1/Figures/Scheme1.pdf}
\caption{Scheme of Tengiz--Koargalzhyn depression.}
   \label{fig:scheme1}
\end{sidewaysfigure}

Update: new figure

Answer 1

Enclosing your graphics in \fbox shows that the image is surrounded by white space that is considered in the image size, so the caption is printed, but beyond the page limit.

You have to measure the padding and then do

\includegraphics[trim=4cm 8cm 4cm 2cm,clip]{imagefile}

where the dimensions are just a wild guess. They represent, in order, the amount of trimming at the left, bottom, right and top.
