(require '[pdfboxing.split :as pdf])List of PDDocument pages 1 through 8
(pdf/split-pdf :input "pdfs/clojure.pdf" :start 1 :end 8)Splits the PDF into single pages as a list of PDDocument
(pdf/split-pdf :input "pdfs/clojure.pdf")Splits the PDF in half and writes them to disk as clojure-1.pdf and clojure-2.pdf
(pdf/split-pdf-at :input "pdfs/clojure.pdf")Splits into two PDFs, the first having 5 pages and second has rest
