I-DiffPDF isetshenziselwa ukuqhathanisa amafayela amabili e-PDF.

Ngokuzenzakalelayo isiqhathaniso singokwamagama akupheya ngayinye yamakhasi, kodwa ukuqhathanisa uhlamvu ngohlamvu nakho kuyasekelwa (isb., ezilimini zelogographic). Futhi kukhona nokusekelwa kokuqhathanisa amakhasi ngokubukeka (isibonelo, uma umdwebo ushintshiwe noma uma isigaba sifomethwa kabusha, noma ifonti ishintshiwe). Kungenzeka futhi ukuqhathanisa amakhasi athile noma ububanzi bekhasi. Isibonelo, uma kunezinguqulo ezimbili zefayela le-PDF, enye inamakhasi 1-12 kanti enye inamakhasi 1-13 ngenxa yekhasi elengeziwe elengeziwe njengekhasi lesi-4, zingaqhathaniswa ngokucacisa ububanzi bamakhasi amabili, 1-12 elokuqala kanye no-1-3, 5-13 kwelesibili. Lokhu kuzokwenza i-DiffPDF iqhathanise amakhasi kumapheya (1, 1), (2, 2), (3, 3), (4, 5), (5, 6), njalonjalo, kuya ku-(12, 13).

Izibonelo ezimbalwa zamafayela e-PDF anikezwa ku-inthanethi ukuze ukwazi ukuwazama. Amafayela e-PDF angalayishwa asuka ku-GUI (ngokucindezela izinkinobho zeFayela #1 nethi File #2), noma ngokuwacacisa emugqeni womyalo. Ulwazi olwengeziwe luyatholakala kumathuluzi ohlelo kanye nebhokisi elithi Mayelana.
