Aşağıdaki python betiği herhangi bir Mac üzerinde çalışacaktır (Snow Leopard ve üstü). Komut satırında art arda PDF dosyaları ile bağımsız değişken olarak kullanılabilir veya Automator'da Kabuk Betiğini Çalıştır eylemine girebilir ve bir Hizmet (Mojave'de Hızlı Eylem) yapabilirsiniz.
Koddaki çıktı görüntüsünün çözünürlüğünü ayarlayabilirsiniz.
Senaryo ve Hızlı Eylem github indirilebilir.
