\documentclass{article} \usepackage{graphicx} \usepackage{fitbox} \begin{document} We start from an image at maximal size: {\centering\fitbox{\includegraphics{vitruvian}}\par} Now it is resized. Here we allow down to 50\% of scale: {\centering\fitbox[minheight=0.5\fitboxnatheight, minwidth=0.5\fitboxnatwidth]{\includegraphics{vitruvian}}\par} Now we make the figure smaller: {\centering\fitbox[maxwidth=\fitboxnatwidth, maxheight=\fitboxnatwidth]{\includegraphics{vitruvian}}\par} {\centering\fitbox[maxwidth=\fitboxnatwidth, maxheight=\fitboxnatwidth]{\includegraphics{vitruvian}}\par} We leave some space, so the full size figure would not fit anymore: {\centering\fitbox{\includegraphics{vitruvian}}\par} The figure is now on the next page. Let us leave some space under the next figure: {\centering\fitbox[minheight=0.5\fitboxnatheight, minwidth=0.5\fitboxnatwidth, belowboxspace=\baselineskip]{\includegraphics{vitruvian}}\par} We left some space for a caption. \end{document}
