I have a presentation in pdf file with two slides per page.
I want a presentation in pdf file with one slide per page.
I tried using ImageMagick:
convert -crop 1x2@ orig.pdf t2.pdf
It divided the slides, but didn't crop them. In new file slides had whitespace on half of the page. I added
convert -crop 1x2@ orig.pdf +repage t6.pdf
It only worked on every second slide. Odd numbered slides still had the white space.
