I want to use yhe adjustbox package to include graphics in beamer presentations. I prefer it over graphicx because it has max size option which only scales the figure when its size is larger than a certain size.

But I've found a problem when I need to select a page from a multipage figure (usually made with documentclass[tikz]{standalone}). When using includegraphics it's possible to use page=x (defined in pdftex.def) option to select which page to be included but this option is not available in adjustbox. Therefore the best command I could do to include certain page from a multipage pdf file with fixed maximum size in beamer is:

newcommand{mygraphic}[2]{%

     parcentering

     adjustbox{max size={textwidth}{.9textheight}}%

        {includegraphics[#1]{#2}}par}

where #1 is an optional parameter used to fix page selection when needed and #2 is the mandatory filename.

My questions are:

1. Is it possible to avoid using includegraphics inside adjustbox if I want to use page=x option?


2. Is it possible to fix max size with a general adjustboxset command? (I think it isn't with export class option but I'm not sure)

This works for me:

documentclass{article}

usepackage{graphicx}

usepackage[export]{adjustbox}

begin{document}



centering % just to avoid overfull box

includegraphics[page=2,max size={textwidth}{0.9textheight}]{l3fp}



end{document}

The adjustbox v1.1 from 2018/04/08 now correctly supports the page key. Instead of using the export option you can just use the macro adjustimage{<options>}{<filename>}. Instead of using centering just use the center key at the end.

usepackage{adjustbox}[2018/04/08]



newcommand{mygraphic}[2]{%

     parnoindent

     adjustimage{#1,max size={textwidth}{.9textheight},center}{#2}%

     par

}

After bouncing back between this and this other question, I decided I wanted to both set global keys for adjustbox (part 2 of your question) and sometimes also use page=… (part 1).¹ So I did this—note the use of capitalized Export:

documentclass{article}

makeatletter



% Load graphicx first and save its original includegraphics

usepackage{graphicx}

letorig@includegraphicsincludegraphics



% Using the capitalized 'Export' option replaces includegraphics with

% adjincludegraphics

usepackage[Export]{adjustbox}



% Set some global adjustbox keys

adjustboxset{trim=0.5in 0in}



% Define a new three-argument command:

%   includegraphicspage{adjbox args}{graphicx args}{filename}

newcommand{includegraphicspage}[3]{%

  adjustbox{#1}{orig@includegraphics[#2]{#3}par}}

makeatother

This allows me to do all of the following and have my adjustboxset options apply in every case:

begin{document}



% This is actually adjincludegraphics; 'page' won't work

includegraphics{singlepage.pdf}



% Pass an argument for graphicx

includegraphicspage{page=3}{multipage.pdf}



% Also pass arguments for adjustbox

includegraphicspage[width=textwidth]{page=3}{multipage.pdf}



end{document}

¹ Why? Mainly because I already had a long document with many includegraphics. It was easier to modify the few appearances of multi-page images.
