# \pdfimageresolution with Luatex 0.95 (TeXLive 2016)

I tried to compile some old .tex file which has an instance of \pdfimageresolution=72 in the preamble. The file compiles fine with pdftex but does not compile with luatex. I'm pretty sure this was working in TeXLive 2015.

Has something changed with Luatex 0.95? Do I have any alternative to \pdfimageresolution=72?

Here is a small example for testing purposes:

%compile with Lualatex
\documentclass{article}
\pdfimageresolution=72
\begin{document}
test
\end{document}

• A lot has changed in the recent luatex, most of the \pdf... macros have either been removed or renamed, see the luatex85 package ctan.org/pkg/luatex85?lang=en – daleif Aug 16 '16 at 14:24

Either use the new syntax or load the luatex85 package:

\documentclass{article}
%new:
\pdfvariable imageresolution 72

%old
\usepackage{luatex85}
\pdfimageresolution=72
\begin{document}
test
\end{document}
