Combine each two pages to single from pdf book
I have such a pdf opened by Okular with Facing pages view mode (center first page).
I want to get all the two-pages view pictures, so manually crop them one by one.
How could extract them to pictures with combining two pages as single one?
You can use pdfjam from texlive-core to do this:
pdfjam --landscape --nup '2x1' --outfile output.pdf -- doc.pdf -;
