Latex includepdf how to pass offset from command

Question

my goal is not to hardcode the offset in the includepdf command

so instead of

\newcommand{\myscale}{0.90}
\includepdf[scale=\myscale,offset=0mm -5mm,angle=90,pagecommand=\subsection{my title}]{file.pdf}

it would be great to write something like this

\newcommand{\myscale}{0.90}
\newcommand{\offset}{0mm -5mm}
\includepdf[scale=\myscale,offset=\offset,angle=90,pagecommand=\subsection{my title}]{file.pdf}

in fact, it is working for the numerical scale value but not for the offset string.

Answer 1

As a workaround, you use two separate macros:

\documentclass{article}

\usepackage{pdfpages}


\begin{document}


\newcommand{\myscale}{0.90}
\newcommand{\xoffset}{0mm}
\newcommand{\yoffset}{-5mm}
\includepdf[scale=\myscale,offset=\xoffset{} \yoffset,angle=90,pagecommand=\subsection{my title}]{example-image-duck}


\end{document}
