Happy New Year to all of you,
I have a question I could not find an answer to in the forum. Is there a possibility to identify the orientation of a PDF file? I have about 2000 PDFs and a lot of them are scanned double pages (so landscape) PDFs. These I want to process further to split the double pages with Abby FineReader, as this OCR software is doing this automatically.
There is a way to do that with pictures – but this does not work with the PDFs I tried. So I thought I could determine if the width is greater than the hight sort of thing, but Hazel does not offer that (as far as I can see).
Maybe someone knows an apple script or shell script which can do that?
That would be wonderful!

The user Olivetti from MacUser.de https://www.macuser.de/threads/orientierung-eines-pdfs-identifizieren-applescript-bash-hazel.816701/#post-10019083 helped me, finding a way to identify landscape PDFs.

All you need are the Xpdf tools: http://www.xpdfreader.com/download.html

The File passes the Shellscript:

With consideration of the rotation:

Code: Select all

#!/bin/bash
ps=$(pdfinfo "$1" | grep 'Page size')
x=$(echo "${ps}" | awk {'print $3'})
y=$(echo "${ps}" | awk {'print $5'})
r=$(echo "${ps}" | grep -o 'rotated.*' | awk '{print $2}')

export LC_ALL=C
x=$(printf "%.0f" "${x}")
y=$(printf "%.0f" "${y}")

[[ "${r}" -eq "0" ]] && [[ "${x}" -lt "${y}" ]] && exit 1 || exit 0


Without consideration of PDF rotation:

Code: Select all

 
#!/bin/bash
ps=$(pdfinfo "$1" | grep 'Page size')
x=$(echo "${ps}" | awk {'print $3'})
y=$(echo "${ps}" | awk {'print $5'})

export LC_ALL=C
x=$(printf "%.0f" "${x}")
y=$(printf "%.0f" "${y}")

[[ "${x}" -lt "${y}" ]] && exit 1 || exit 0


Works great for me!
