6 slides on a page:
pdfjam --nup 2x3 --frame true --noautoscale false --delta "0.2cm 0.3cm" --scale 0.95 IN.pdf --outfile OUT.pdf
pdfcrop is nice and simple (but the pdf might grow to 7 times the original size...)
pdfcrop in.pdf out.pdf
To get a small margin use:
--margins '5'
Gui tool (manual framing, but with numbers):
pdfshuffler
pdfjoin -o DESTINATION.pdf 1.pdf 2.pdf 3.pdf ...
If it rotates pages, go directly to pdfjam:
pdfjam --fitpaper 'true' --suffix joined --outfile DESTINATION.pdf -- 1.pdf 2.pdf 3.pdf ...
Use ImageMagick?:
convert *jpg -page a4 out.pdf
Dumping real text in the pdf:
pdftotext in.pdf out.txt
Convert pdf to jpg:
convert -density 300 -trim IN.pdf -quality 100 OUT.jpg
Will create n jpgs (if there are n>1 page in the PDF), named OUT-0.jpg OUT-1.jpg etc.
