pdf-to-images

Clojure wrapper for the PDFBox that converts a page range of a PDF document to images.

Installation

Add the following dependency to your project.clj file:

[pdf-to-images "0.1.2"]

Usage

Import namespace example:

(ns hello-world.core
  (:require [pdf-to-images.core :refer :all]))

Basic usage example:

(let [image-paths (pdf-to-images (clojure.java.io/file "path-to-pdf") image-to-file)]
  (prn (str "Images count: " (count image-paths)))
  (map prn image-paths))

;; "Images count: n"
;; "path-to-image-0"
;; "path-to-image-1"
;; ...
;; "path-to-image-n-1"

The same with key-value pair parameter - pathname will be used if pdf-file is not specified (= nil):

(let [image-paths (pdf-to-images nil image-to-file :pathname "path-to-pdf")]
  (prn (str "Images count: " (count image-paths)))
  (map prn image-paths))

;; "Images count: n"
;; "path-to-image-0"
;; "path-to-image-1"
;; ...
;; "path-to-image-n-1"

With-options usage example:

(let [image-paths (pdf-to-images (clojure.java.io/file "path-to-pdf")
                                  image-to-file
                                  :start-page 0
                                  :end-page 1
                                  :dpi 100
                                  :ext "jpg")]
  (prn (str "Images count: " (count image-paths)))
  (map prn image-paths))

;; "Images count: 1"
;; "path-to-image-0"
