In a LaTeX document I have about 70 images which are scaled using the graphicx-package and \includegraphics[scale=0.8]{foo.pdf}

where the scaling factor varies. Now I would like to rescale them all with a common factor, like

\includegraphics[scale=\factor * 0.8]{foo.pdf}

except that is no LaTeX syntax. Can anyone provide a smart solution?

\includegraphics[scale=\factor , scale= 0.8]{foo.pdf}
  • Thanks a bunch! That was quite a bit more elementary to solve than I anticipated. – Holtor Aug 11 '14 at 16:11
  • I would have thought [scale=0.8, scale=\factor]! – Yiannis Lazarides Aug 11 '14 at 16:21
  • @YiannisLazarides in an ideal world (not this one, admittedly) multiplication is commutative. – David Carlisle Aug 11 '14 at 16:39

    I wonder if you could explain this a bit: it seems entirely non-intuitive to me (keys normally override each other, so I'd expect the scale here to be 0.8 not 0.8 times \factor). – Joseph Wright Aug 11 '14 at 16:48
  • @JosephWright includegraphics keys don't overight they are cumulative and read left to right, mainly so that [height=1cm,angle=90] makes something 1cm wide but [angle=90,height=1cm] makes something 1cm high the fact that you can use two scale is an artifact of the implementation (and not something I've done before this answer I suspect:-) – David Carlisle Aug 11 '14 at 21:00

Another solution with fp package.
