I use the latex package ‘beamer’ (with lyx) to create presentations for various talks etc.
For a forthcoming conference I was asked by the organisers to create a 3-up pdf file similar to what Powerpoint users produce.
I struggled with pgfpages for a while, and even contemplated writing my own pgfpages layout. However, common sense prevailed and I found the pdfjam package.
So, once my presentation is ready,in the lyx preamble I add the ‘handout’ option to the class options in “Document/Settings/Document Class” so it reads: 12pt, handout
Then in the Latex Preamble I add:
and remove any ‘\setbeamertemplates’ which may conflict with a nice plain layout.
I then export this as a pdf file with File/Export/PDF (pdflatex)
Open this in acrobat and it *should* be 1 slide per page.
To convert this to 3 slides per page, with a frame around each slide, and the slides shifted to the left of the page (leaving the RHS of the page for people to write notes/comments) use this pdfjam command:
pdfnup presentation.pdf --nup 1x3 --delta "0.5cm 1.5cm" --frame true --offset "-4.0cm 0" --scale 0.80
