It’s easy to get individual pages from a PDF with PerlMagick.
I was playing around with PerlMagick and a PDF with two pages inside, when a question hit me: how do I figure out how many pages are there in the PDF and iterate through them?
Some searching was not useful to this regard, because either I found stuff applicable to PHP, or walls of text where searching for pages, multiple ecc. did not yield a clear result.
Then this example came in my vision cone:
Wait. A. Minute.
Are we saying that an
Image::Magick object is actually a blessed array
reference when reading multiple images (like a PDF)? It seems… so:
From this point, the path goes downwards with a gentle decline, through an
amazing country landscape. The array contains indeed one item for each page,
and each item in the array can itself be used as an
(this time it’s a blessed
SCALAR instead, but who cares?).
So there we go, to know how many pages are in the PDF we can do like this:
use v5.24; use Image::Magick; my $pm = Image::Magick->new; $pm->Read('myfile.pdf'); my $n_pages = $pm->@*;
Enjoy and stay safe!
